Server Quality Checklist

75%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v1.21.1

  • Disambiguation5/5

    Each tool targets a specific resource and action (e.g., create-monitor vs update-monitor, search-logs vs aggregate-logs). Even with many similar patterns, descriptions clearly differentiate them. The search-tools tool further aids navigation.

    Naming Consistency5/5

    All tool names use a consistent snake_case verb-noun pattern (e.g., create-downtime, list-hosts, get-monitor). Verbs like 'aggregate', 'search', 'analyze' are distinct and predictable.

    Tool Count2/5

    With 166 tools, the count is extremely high for a single MCP server. While Datadog's API surface is broad, this overwhelms agents and makes selection difficult despite the search-tools helper.

    Completeness3/5

    The server covers CRUD operations for many domains (monitors, SLOs, dashboards, synthetics, security, teams, status pages), but notable gaps exist, such as missing create/update for notebooks, network devices, and hosts beyond listing.

  • Average 3.6/5 across 166 of 166 tools scored. Lowest: 2.9/5.

    See the Tool Scores section below for per-tool breakdowns.

How to sync the server with GitHub?

Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description is consistent. However, the description adds no extra behavioral details beyond 'Get', such as output structure, potential errors, or whether it requires authentication. With annotations present, minimal extra context is needed, but none is provided.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 8 words, front-loaded with action. Zero wasted words. Every part is essential and immediately conveys the tool's purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description lacks details about return values ('detailed information' is vague). With no output schema, the agent needs hints about the response structure. No mention of expected outcomes or error handling. Incomplete for a tool with no output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 100% coverage with a clear description for the only parameter ('issueId'). The tool description does not add any additional meaning beyond the schema. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb and resource: 'Get detailed information about a specific error tracking issue.' It distinguishes from the sibling 'list-error-tracking-issues' by implying a single item retrieval, but does not explicitly contrast. Overall clear but could be more specific about what 'detailed information' includes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like 'list-error-tracking-issues'. There is no mention of prerequisites, typical workflows, or cases where this tool is preferred. The description provides no usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate write operation (readOnlyHint=false) and open world (openWorldHint=true), but description adds no further behavioral insights like idempotency, permissions, or side effects beyond 'Send'.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 12 words, no unnecessary text. Front-loaded with the key action and purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Minimal description given 7 parameters, no output schema, and many siblings. Lacks details on return values, impact, or how this event integrates with DORA tracking.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers 100% of parameter descriptions, so baseline 3 applies. Description adds no extra parameter meaning beyond what's already in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states sending a DORA incident event for tracking change failure rate and MTTR. However, fails to differentiate from similar sibling tool 'create-incident', which also likely creates incidents.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'create-incident' or 'send-dora-deployment'. Lacks context on prerequisites or scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate mutation (readOnlyHint=false) and openWorldHint=true. Description adds no behavioral traits like feedback on missing team, idempotency, or required permissions beyond stating the update action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 10 words, front-loaded with action. Efficient, but could mention the required teamId parameter for clarity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema and description does not explain response format, error cases, or prerequisites (e.g., team must exist). Minimal completeness for a mutation tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter descriptions. Tool description merely restates the parameter fields (name, handle, description) without adding new meaning like format constraints or behavior of handle uniqueness.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'Update' and resource 'Datadog team' with specific fields (name, handle, description), distinguishing it from siblings like create-team, delete-team, get-team.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like create-team or get-team. The description only states what it does without context on prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate a write operation (readOnlyHint=false) with possible side effects (openWorldHint=true), but the description adds no behavioral traits like authentication needs, resource limits, or what happens to existing schedules.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, front-loaded sentence of 10 words is concise, but it omits important information that could be added without becoming verbose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (5 parameters, nested object, no output schema), the description is too minimal. It fails to explain the return value or the purpose of key parameters like query and rule beyond the schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% with detailed parameter descriptions. The tool description adds no extra meaning beyond the schema, so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'create' and resource 'fleet schedule', specifying it is for automated upgrades with maintenance windows. This distinguishes it from sibling tools like create-fleet-deployment-upgrade.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives such as create-fleet-deployment-upgrade or trigger-fleet-schedule. No prerequisites or when-not-to-use information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate write operation (readOnlyHint: false) and open-world side effects. The description adds no extra behavioral details, such as permissions required, idempotency, or immediate application of the filter. It does not disclose any traits beyond the basic action.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence, front-loaded with the core purpose. It is efficient, but could include slightly more context without becoming verbose, such as mentioning the return value or the purpose of retention filters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having 6 parameters and no output schema, the description does not explain what the tool returns or how the creation affects the system. It lacks information about retention filter semantics, error conditions, or confirmation of success. More detail is needed for full contextual completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with each parameter described in the input schema. The tool description only mentions three parameters (event type, sample rate, query) and does not add meaning beyond the schema. It neither clarifies relationships nor constraints, so it meets the baseline for high coverage but does not exceed it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Create a RUM retention filter', specifying the verb (create) and the resource (RUM retention filter). It distinguishes itself from sibling tools like 'create-apm-retention-filter' and other create tools for different resources, making it unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as when to create vs. update a filter, or any prerequisites. There are no contextual hints for usage decisions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructiveHint=true, so description adds no new behavioral context. It doesn't mention irreversibility, cascading effects, or lack of return value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise single sentence. However, given the destructive nature, a brief warning or note on irreversibility would improve without sacrificing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a destructive operation with no output schema and simple input, the description is too minimal. It could mention the operation has no return value or confirm deletion, which is critical context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear parameter description. The description's 'by ID' repeats the schema. No additional meaning about ID format, source, or validation is provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (delete), resource (APM retention filter), and method (by ID). It distinguishes from sibling tools like delete-rum-retention-filter by specifying the resource type.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, no mention of prerequisites such as filter existence or permissions. The description provides no context for the agent to decide between this and other delete tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description adds only pagination detail. No contradiction, but lacks additional behavioral context such as default ordering or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no wasted words. Could be expanded slightly with more context, but remains concise and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, so the description should compensate by describing return values or structure. It only says 'List ...', which is insufficient for an agent to understand what fields or format to expect.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema covers 100% of parameters with descriptions. The description does not add extra meaning beyond the schema, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states verb (List) and resource (Datadog incidents), and mentions pagination. However, it does not differentiate from sibling tool 'search-incidents', which may also list incidents but with filtering capabilities.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like 'search-incidents' or 'get-incident'. Does not specify prerequisites or context for use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety and variability profile. The description adds no further behavioral details (e.g., pagination, rate limits), but does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with verb and resource. Efficient and to the point, though could benefit from minor elaboration.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite 6 parameters and no output schema, the description omits what a security signal is, the return format, or any context beyond 'searching'. Annotations help but additional behavioral details would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% (all 6 parameters have descriptions). The tool description adds no additional meaning beyond the schema, meeting the baseline for high coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'search' and resource 'Datadog security monitoring signals', indicating a query-based retrieval tool. It distinguishes from siblings like 'get-security-signal' (single) and 'list-security-rules' (different resource), but does not explicitly differentiate from other search tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as 'get-security-signal' or other search tools. The description implies usage but provides no explicit context or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate this is a write operation (readOnlyHint=false) and dynamic (openWorldHint=true). The description only repeats 'Update', adding no additional behavioral context such as side effects, permissions, or reversibility.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no extraneous words. It effectively communicates the core action and updatable fields, though it could be slightly more informative.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, and the description does not mention return values or confirm whether the update is successful. It also lacks constraints like requiring an existing filterId. For a mutation tool with 5 required parameters, more context is needed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all 5 parameters. The description lists the fields but does not add meaning beyond what the schema already provides, hence baseline score of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Update' and the resource 'APM retention filter', and lists the specific fields that can be updated (name, query, rate, enabled state). This differentiates it from sibling tools like create, delete, get, and list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool vs alternatives such as create or delete. There is no mention of prerequisites, context, or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description only says 'Update,' but does not clarify whether it replaces all fields or merges, nor does it mention side effects, error handling, or authentication needs. Annotations (readOnlyHint=false, openWorldHint=true) partially cover mutation but the description should add more behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise (5 words, one sentence), but it sacrifices meaningful detail. Still, it is efficiently short and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 7 parameters, 4 required, no output schema, and moderate complexity, the description is insufficient. It does not explain the update semantics (e.g., partial vs full replacement) or return value, leaving agents underinformed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents all parameters. The description adds no extra parameter-specific details, earning the baseline score of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (update) and resource (existing Datadog dashboard), distinguishing it from related tools like create-dashboard and delete-dashboard.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no prerequisites (like the dashboard must exist), and no exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=false and openWorldHint=true, but the description adds no additional behavioral context, such as whether it performs a partial update or full replacement, or any side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no wasted words, but it lacks structure that could be improved with bullet points or additional context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (9 parameters, no output schema), the description is too minimal. It fails to explain the return value or any impacts of updating a test, making it incomplete for an agent to use correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description does not add any meaning beyond what the schema already provides for each parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Update' and the resource 'existing Synthetics API test', distinguishing it from sibling tools like 'create-synthetics-test' and 'delete-synthetics-test'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as when to create vs update, or prerequisites like having the publicId.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate write operation (readOnlyHint=false) but description does not disclose potential side effects, idempotency, or concurrency behavior. No mention of authorization needs or resource limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence that is front-loaded with key information. No unnecessary words, though could be slightly more structured with line breaks.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Missing output schema, so description does not explain return values. While description covers aggregation types and filtering, it does not mention that 'path' is required for distribution metrics or detail groupBy structure. Adequate but not complete for a 6-parameter tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers all 6 parameters with descriptions. Description adds a high-level summary ('count or distribution, with filters and group-by') but does not provide additional meaning beyond the schema. Baseline score for high coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'create', resource 'metric based on log data', and specifies the type (count or distribution) with filters and group-by, distinguishing it from sibling tools like create-rum-metric.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like create-rum-metric or create-spans-metric. Does not mention prerequisites or when not to use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Description does not add behavioral details beyond annotations. Annotations already indicate destructiveHint=true, but no info on reversibility, permissions, or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with no wasted words. Could be improved by front-loading key info, but adequate.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a delete tool with one parameter, description is mostly adequate but missing details like whether response is empty or includes deleted object. No output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear description and example. Description adds no extra meaning; baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states verb 'Delete', resource 'Datadog dashboard', and method 'by ID'. Distinguishes from sibling delete-* tools for other resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like update-dashboard or get-dashboard. No prerequisites or when-not-to-use information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructiveHint: true and readOnlyHint: false, so the description adds minimal value. It does not disclose any additional behavioral traits like cascading effects, reversibility, or permissions required beyond what annotations imply.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence without extraneous words. It is appropriately front-loaded and concise, though marginally brief.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple deletion tool with one parameter, the description is adequate but could benefit from mentioning prerequisites or consequences. Given the annotations cover destructive nature, it is minimally complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with the parameter pageId described as 'The status page ID to delete'. The description adds no new meaning beyond 'by ID', so it meets the baseline but does not enhance understanding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'delete' and resource 'status page', and specifies deletion by ID. It effectively distinguishes from sibling tools like create-status-page, update-status-page, and get-status-page.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as other delete tools or conditions under which deletion is appropriate. No exclusions or prerequisites are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The annotations already declare readOnlyHint=true and openWorldHint=true. The description adds no additional behavioral context beyond stating the purpose. It does not mention pagination, ordering, or what constitutes an 'automated fleet upgrade schedule', so the agent has no extra insight into behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence that conveys the core purpose without any extraneous words. It is efficient and front-loaded, making it easy to scan.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description does not explain what the response contains (e.g., schedule IDs, details, statuses). While the tool is simple and annotations provide some context (read-only, open world), an agent would benefit from knowing what information is returned to use with sibling tools like get-fleet-schedule or trigger-fleet-schedule.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    There are zero parameters, so the baseline is 4. The description does not need to explain parameters because none exist. It correctly implies no inputs are required.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List automated fleet upgrade schedules' clearly states the action (list) and the resource (automated fleet upgrade schedules). It distinguishes from sibling list tools like list-fleet-agents and list-fleet-deployments by specifying 'upgrade schedules', but does not differentiate from get-fleet-schedule (single schedule) or trigger-fleet-schedule (action on schedule).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. There is no mention of when to list schedules versus create, update, delete, get, or trigger them. The description lacks context for the agent to decide between this and other fleet schedule tools or other list tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate a write operation (readOnlyHint=false) and potential side effects (openWorldHint=true). The description adds no additional behavioral context, such as permissions or idempotency, but doesn't contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with action and resource, no extraneous words. Efficient and clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 8 parameters and no output schema, the description is minimal. It doesn't explain partial update semantics, the effect on existing SLO corrections, or the role of the required sloCorrectionId. Missing details for safe usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so parameters are documented. The description adds meaning by grouping 'time range' as a conceptual field, but it doesn't map to the actual schema parameters (start, end, duration) precisely. Some parameters like rrule are not mentioned.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'update' and the resource 'SLO correction', and lists which fields can be updated (category, time range, description). This provides a specific purpose, though it could be more distinct from other update tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like create-slo-correction or delete-slo-correction. No prerequisites or context for when an update is appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description adds minimal behavioral context beyond 'statistical computations and grouping'. It does not contradict annotations, but fails to elaborate on behaviors like required time constraints or result format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no unnecessary words. It is front-loaded and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's moderate complexity (6 parameters, aggregation logic) and lack of output schema, the description feels incomplete. It does not explain what the aggregated result looks like or how groups are returned. However, schema descriptions for parameters are thorough, partially compensating.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage for all parameters, so the description adds no additional meaning beyond what is already documented in the schema. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool aggregates CI test data with statistical computations and grouping, which is specific and distinguishes it from other tools like search-ci-tests. However, it does not explicitly differentiate from sibling aggregate tools like aggregate-ci-pipelines, relying on the resource name 'CI test' for distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as search-ci-tests for non-aggregated data or aggregate-ci-pipelines for pipeline data. No when-not or context is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations are minimal (readOnlyHint=false, openWorldHint=true). The description adds no behavioral details beyond stating it creates the filter. It doesn't mention idempotency, immediate effect, limits, or dependencies, leaving the agent with insufficient info.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no redundancy, efficiently conveys the core purpose and key parameters. The entire description earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple creation tool, the description covers the basic purpose and parameters. However, it omits usage guidelines and behavioral nuances. Given the sibling tools and lack of output schema, it's minimally adequate but not comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has 100% coverage with descriptions for all 4 properties. The description merely paraphrases the parameters ('with query, sample rate, and enable/disable'), adding no new semantic value. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Create'), the resource ('APM retention filter'), and the key properties (query, sample rate, enable/disable). It effectively distinguishes from sibling tools like update and delete filters.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, no prerequisites, no when-not-to-use advice. Siblings like update-apm-retention-filter exist but no comparative context is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate write operation (readOnlyHint=false) and potential external effects (openWorldHint=true). The description adds no additional behavioral context beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, front-loaded with the key purpose, and contains no fluff. It could be slightly more detailed while remaining concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description fails to mention what the tool returns (e.g., case ID), and given the lack of output schema, this is a gap. It also doesn't provide additional context like prerequisites or side effects.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All parameters are described in the input schema, so the description adds no extra semantic meaning. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Create'), the resource ('new case'), and the domain ('Datadog Case Management'), distinguishing it from sibling tools that create other resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool vs alternatives like create-incident or create-downtime. There is a hint in the param description for typeId, but no overall usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate mutation (readOnlyHint=false) and open world (openWorldHint=true). The description confirms creation but adds no extra behavioral context such as idempotency, rate limits, or result. It is adequate but not enriched beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence with front-loaded purpose. The examples in parentheses provide efficient context. Could be slightly more structured but is appropriately concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite high schema coverage, the description lacks explanation of return values (no output schema), fails to address the complex 'options' nested object, and provides no behavioral context for a 7-parameter tool. Incomplete for effective use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description adds no additional meaning to parameters beyond the schema descriptions. It does not compensate for any gaps.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the verb 'Create' and resource 'Datadog monitor', and provides examples of monitor types (metric alert, log alert, etc.). This clearly differentiates it from sibling tools like update-monitor or delete-monitor.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like create-dashboard or create-slo. No prerequisites, exclusions, or context for selection are mentioned.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=false and openWorldHint=true. The description adds no additional behavioral context beyond the action itself, such as side effects, quota implications, or naming constraints. It does not contradict annotations but fails to leverage the openWorldHint to provide deeper insight.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, front-loading the purpose with no extraneous text. Every word earns its place, making it highly efficient for an agent to quickly understand the tool's function.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description does not indicate what the tool returns (e.g., the created application ID or metadata). The openWorldHint suggests side effects but none are described. For a simple creation tool, the description is minimal but lacks completeness for agents needing post-creation guidance.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with both parameters described. The description lists types in parentheses but this is redundant with the enum defined in the schema. No additional semantic meaning is provided beyond what the schema already offers, resulting in a baseline score.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states 'Create a new RUM application' followed by a list of supported types, clearly indicating the action and resource. This distinguishes it from related tools like update-rum-application, delete-rum-application, and list-rum-applications, providing specific verb+resource differentiation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate this is a write operation (readOnlyHint=false) and open world (openWorldHint=true). The description only restates the core purpose without revealing behavioral traits like idempotency, side effects, or what happens on duplicate names. Minimal value added beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no filler. It efficiently conveys the core purpose, though it could benefit from structured bullet points for complex use cases.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema is provided, and the description does not mention the return value or response format. For a tool with 4 required parameters, this leaves uncertainty about what happens after creation, making it less complete for decision-making.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents all parameters. The description adds no extra meaning beyond mentioning 'component or group', which aligns with the 'type' enum. Baseline score is appropriate.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Create') and the resource ('component or group on a status page'). It distinguishes from sibling tools like 'create-status-page' and 'create-status-page-degradation' by specifying the exact entity being created.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool vs alternatives. Usage is implied by the name and description, but there is no mention of prerequisites, context, or conditions that would help an agent decide.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with no redundancy, front-loaded with purpose and key parameters.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Adequate for a simple creation tool but lacks usage guidelines and behavioral details. With no output schema, the description does not explain return value, which is a minor gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers all 3 parameters with descriptions (100% coverage). The description merely lists them, adding no extra meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'create' and resource 'Datadog team', specifying required fields (name, handle, description). This distinguishes it from sibling tools like update-team or delete-team.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use create-team versus alternatives like update-team or delete-team. Does not mention prerequisites, context, or when not to use.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The annotations already declare destructiveHint=true, so the description's 'Delete' is consistent. However, it adds no additional behavioral context like irreversibility, permission requirements, or side effects. The description neither contradicts nor enriches the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single sentence that is front-loaded with the action and resource. No redundant words; every word is functional.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple deletion tool with one required parameter and no output schema, the description is minimally adequate. It could be improved with a note about permanence or confirmation, but given the destructiveHint annotation, the current state is acceptable.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the parameter description explains what metricId is. The tool description reinforces 'by name', but adds no new semantic detail beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the action 'Delete' and the resource 'log-based metric', and specifies the key parameter 'by name'. While it doesn't explicitly differentiate from other delete tools, the resource specificity is clear enough to avoid confusion with most sibling tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., update-logs-metric, get-logs-metric). It does not mention prerequisites, such as whether the metric must exist first, or any consequences.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint and openWorldHint, indicating a safe read operation. The description adds 'detailed information' but no additional behavioral traits beyond what annotations imply.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with clear verb and object, no unnecessary words, effectively front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Adequate for a simple read operation with one parameter and no output schema. Could mention the nature of 'detailed information' but not essential.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the description does not add further meaning to the single parameter 'id'. Baseline 3 applies as per the rubric.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves detailed information about a specific fleet schedule. The verb 'get' and resource are specific, and it distinguishes from siblings like list-fleet-schedules and trigger-fleet-schedule.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as list-fleet-schedules or trigger-fleet-schedule. No prerequisites or context provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description adds minimal behavioral context beyond annotations. Annotations already declare readOnlyHint=true and openWorldHint=true, so the description correctly implies read-only search but misses details like pagination, response format, or rate limits. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, front-loaded sentence with no wasted words. Every word contributes to the purpose, making it easy to parse quickly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema), the description is adequate for basic understanding. However, without an output schema, it would benefit from briefly describing the return value (e.g., list of metric names, metadata).

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 100% schema description coverage, the baseline is 3. The description provides an example ('e.g. system.cpu') which adds practical guidance beyond the schema. However, it does not elaborate on formatting, wildcards, or query syntax.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'Datadog metrics' with the qualifier 'by name pattern'. This effectively distinguishes it from generic 'get-metrics' and from siblings like 'list-active-metrics' or 'query-metrics', though it doesn't explicitly contrast them.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus other metric-related tools such as 'list-active-metrics' or 'query-metrics'. There are no prerequisites, exclusions, or alternative recommendations mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description only needs to add behavioral context. It correctly notes the listing nature and optional filtering, but fails to mention pagination behavior (page, pageSize) or that the result may be large. It does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence that front-loads the action and resource. No unnecessary words or repetition. Every part earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and a parameter count of 7, the description is somewhat brief. It does not specify what the returned list contains (e.g., monitor IDs, names, statuses) or any sorting/ordering. However, the tool name and filtering hints provide enough context for an AI agent to infer common behavior. More detail on pagination would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description adds minimal value beyond the schema by summarizing filters as 'name, tags, or state', but does not elaborate on 'extractFields', 'pageSize', or 'page'. It does not enhance understanding of the more complex parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('List') and resource ('Datadog monitors') with optional filtering. It distinguishes from the sibling 'get-monitor' (which retrieves a single monitor) by implying a list operation. However, it only mentions three filtering dimensions (name, tags, state) while the schema includes seven parameters, including pagination and field extraction, so the purpose is clear but slightly under-specified.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance is given on when to use this tool versus alternatives. While the sibling list tools (e.g., 'list-hosts') differ by resource, there is no mention of when listing monitors is appropriate, what prerequisites exist, or when to prefer 'get-monitor' instead. The description relies entirely on implicit understanding.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, covering safety and scope. The description adds no further behavioral insights (e.g., side effects, rate limits) beyond restating 'by name'. Given annotation coverage, the description meets minimum transparency but does not enhance it.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single 8-word sentence, front-loaded with the verb and resource. No extraneous information; every word is necessary.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, the description could provide more context about what a 'definition' includes (e.g., properties, metadata). However, given the tool's simplicity (1 param, read-only), the description is minimally sufficient but leaves the agent guessing about the response structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with a clear description and example for the 'metricId' parameter. The description merely restates 'by name', adding no semantic value beyond the schema. Baseline score of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'rum-based metric definition', specifying retrieval by name. It differentiates from sibling tools like 'list-rum-metrics' (which returns multiple) and 'get-metrics' (more general), though it does not explicitly distinguish from 'get-metric-metadata'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives like 'list-rum-metrics' or 'get-metrics'. The description implies use when the metric name is known, but provides no context about prerequisites or scenarios where other tools are preferable.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, so the description does not need to state read-only behavior. The description adds 'detailed' but does not specify what details are included (e.g., status, times, components). No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence (10 words) that conveys the tool's purpose without any superfluous content.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read operation with two well-described parameters and read-only annotations, the description is mostly adequate. However, it lacks details about response structure or error behavior, which would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage with descriptions for both parameters. The description adds no additional parameter meaning beyond what the schema provides, so baseline score of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets detailed information about a specific maintenance window, distinguishing it from list operations. However, it does not explicitly differentiate from sibling tools like get-status-page or get-status-page-degradation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., list-status-page-maintenances). There is no mention of prerequisites or context for usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations provide readOnlyHint and openWorldHint. The description adds that it lists metrics from a given time with optional filters but does not disclose additional behavioral traits like pagination, definition of 'active', or rate limits. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 15 words, front-loaded with action and resource. Every part is relevant and concise with no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Adequate for a simple read tool with three parameters and no nested objects, but lacks details on what 'active' means, return format, or pagination. Without an output schema, the description could provide more context about the response structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with descriptions for 'from', 'host', and 'tagFilter' already present. The description merely restates these parameters ('from a given time, optionally filtered by host or tag') without adding new meaning or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'List active metrics' with a specific verb and resource. It specifies the temporal scope ('from a given time') and optional filters. While distinct from siblings like 'list-metric-tags' and 'get-metrics', it could more explicitly differentiate the concept of 'active' metrics from listing all metrics.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use or not use this tool versus alternatives. Sibling tools include 'list-metric-tags', 'list-hosts', 'query-metrics', etc., but the description does not indicate when this tool is preferred or any prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to repeat that. However, it adds no additional behavioral context (e.g., rate limits, cost, or data volume implications) that would help the agent assess risk.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that efficiently conveys the tool's purpose. It could include more detail without becoming verbose, but it is already clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema and the complexity of query tools that may return large datasets, the description lacks information on pagination, response format, timeouts, or data limits, making it incomplete for a realistic use case.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear descriptions for all parameters. The description adds an example query string but no other semantics beyond the schema, so it meets the baseline without exceeding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Query time-series metric data from Datadog' and specifies it supports any Datadog metric query syntax with an example, distinguishing it from sibling tools like get-metrics that likely list available metrics.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide any guidance on when to use this tool versus alternatives like get-metrics or get-metric-metadata, nor does it mention prerequisites or limitations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, indicating safe read behavior. The description adds minimal extra context (e.g., query fields) but does not contradict annotations. For a read-only search tool, the description is adequate but does not elaborate on pagination behavior or result limits beyond schema.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, front-loaded sentence that directly conveys the tool's purpose. No unnecessary words or fluff. Maximally concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a search tool with 4 parameters and no output schema, the description is minimal. It does not explain return format (e.g., list of incident objects) or how to combine query terms. However, annotations and schema cover safety and pagination, so it is minimally adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the description adds little value beyond the schema. It mentions query fields (state, severity, title keywords) which align with the schema's query description. No additional parameter semantics are provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Search' and the resource 'Datadog incidents', and specifies searchable fields (state, severity, title keywords). However, it does not explicitly differentiate from sibling tools like 'get-incidents' which may also list incidents, but the intent is clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool vs. alternatives such as 'get-incident' or 'get-incidents'. It lacks any 'when to use' or 'when not to use' context, leaving the agent to infer usage from the name alone.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate readOnlyHint=false (write operation) but description adds no additional behavioral traits (e.g., idempotency, persistence, response). Does not disclose what the event includes or if there are side effects beyond 'send'.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single, concise sentence front-loading the action and purpose. No unnecessary words; every part contributes to understanding.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Adequate for a straightforward event sender with well-documented schema, but lacks information about return behavior or acknowledgment. openWorldHint suggests potential effects beyond described, which could be elaborated.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers all 5 parameters with descriptions and examples (100% coverage). Description provides context that the event is for tracking deployment frequency and lead time, but does not add per-parameter semantics beyond what schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb ('Send a DORA deployment event') and the resource/purpose ('for tracking deployment frequency and lead time'). It distinguishes from sibling 'send-dora-incident' by specifying 'deployment'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No when-to-use or when-not-to-use guidance. Sibling 'send-dora-incident' exists but description does not differentiate usage contexts, nor does it mention prerequisites or alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate a write operation (readOnlyHint=false) and open world hint. Description adds no extra behavioral context (e.g., error handling, rate limits, idempotency).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no extraneous text. Highly concise and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema and no description of return values or error states. For a simple send operation, this is somewhat acceptable but could be more helpful.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers 100% of parameter descriptions; description adds no additional semantic value beyond what's in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the action 'send' and resource 'log entries', distinguishing it from read/aggregate tools like search-logs and aggregate-logs.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., search-logs, aggregate-logs). The description is purely functional.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description confirms a write operation (consistent with readOnlyHint=false) but does not disclose side effects (e.g., notifications, state transitions) beyond what annotations imply (openWorldHint=true). No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no unnecessary words, immediately conveys the tool's purpose. Ideal conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Simple tool with complete schema and annotations; the description is minimally sufficient. However, it lacks usage context and behavioral details, making it adequate but not exceptional.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with adequate descriptions for both parameters (caseId and status). The description reiterates the enum values already in the schema, adding no new semantics beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Update'), the resource ('status of a Datadog case'), and the allowed values ('OPEN, IN_PROGRESS, CLOSED'). This distinguishes it from sibling tools like create-case or get-case.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., update-incident, create-case). No mention of prerequisites or context such as whether the case must already exist.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description only states 'Update', which implies mutation, consistent with annotations (readOnlyHint false). However, it does not disclose any additional behavioral traits (e.g., whether the update is atomic, if there are side effects, permission requirements, or how partial updates work).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, well-formed sentence that immediately communicates the tool's purpose. Every word is necessary; no fluff or redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the complexity (6 parameters, nested object) and the presence of siblings, the description is minimally adequate. It lists updatable fields but does not clarify if the update is partial or full, or mention that the 'id' is required. No output schema is expected, but the behavioral context is thin.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so parameter descriptions already exist. The description adds a summary of updatable fields but does not explain the 'rule' nested object or the 'versionToLatest' parameter beyond what the schema provides. No meaningful extra semantics.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb (update) and resource (fleet schedule), listing the exact fields that can be modified (name, query, recurrence rule, or status). This clearly distinguishes the tool from sibling tools like create-fleet-schedule, delete-fleet-schedule, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., create, delete, trigger). It does not mention prerequisites, such as the schedule must exist, nor does it indicate whether the update is partial or requires all fields.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate write operation (readOnlyHint=false) and potential side effects (openWorldHint=true). The description confirms 'update' but adds no additional behavioral traits, such as whether changes are incremental or full replacement, or what happens if the metric doesn't exist.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with key information. No unnecessary words or repetition. Efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Minimally adequate for a simple mutation tool with full schema coverage, but lacks details about response, partial updates, or validation. No output schema increases need for behavioral context, which is missing.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All parameters have descriptions in the schema (100% coverage), so the description's mention of 'filter, group-by, or percentile settings' adds no new meaning. It serves as a summary but not extra semantics.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'update', the resource 'log-based metric', and specifies the settings to update: 'filter, group-by, or percentile settings'. This distinguishes it from sibling tools like create- or delete- variants.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or scenarios to avoid. It simply describes the action without context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate readOnlyHint=false (write operation) and openWorldHint=true (possible side effects), but the description adds minimal behavioral context. It does not disclose reversibility, notification behavior, or constraints on status transitions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that conveys the core purpose efficiently. Minor room for improvement by including key constraints, but no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 10 parameters, no output schema, and rich sibling tools, the description overlooks important behavioral details such as return value, status transition rules, and whether updates trigger notifications. More context is needed for full understanding.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents each parameter. The description enumerates some parameter groups (status, schedule, components) but adds no new meaning beyond what the schema provides. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (update), the resource (maintenance window), and the updatable aspects (status, schedule, affected components). It effectively distinguishes from sibling tools like create-, get-, and delete-status-page-maintenance.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when updating a maintenance window but provides no explicit guidance on when to use alternatives, prerequisites, or limitations. It lacks when-not-to-use or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations show readOnlyHint=false (mutation) and openWorldHint=true. The description does not add behavioral details beyond creation; no mention of side effects, permissions, or lifecycle.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with front-loaded verb and resource. No unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a 7-parameter tool with full schema descriptions and no output schema, the description adequately captures the core function. Could expand on subtle distinctions between query fields, but not required.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so parameter meanings are already explicit. The description adds no additional context beyond what the schema provides, earning a baseline of 3.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Create' and the resource 'security monitoring suppression rule', with the specific purpose 'to suppress signals matching a query'. This distinguishes it from sibling tools like delete-security-suppression and list-security-suppressions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., other create tools). It does not specify prerequisites, when not to use, or trade-offs.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Description adds 'Write-gated' which reinforces readOnlyHint=false annotation. However, it lacks details on permissions, side effects, or error behavior. Annotations already cover write nature, so description adds marginal value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with key action and types. 'Write-gated' adds relevant behavioral note. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Tool has 9 parameters with nested objects, no output schema. Description does not mention return value (e.g., created SLO ID) or common prerequisites/errors. Incomplete for a create operation with high complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with detailed parameter descriptions. The description does not add any parameter information beyond what the schema provides. Baseline 3 is appropriate.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'Create a new Service Level Objective' with explicit types (monitor-based, metric-based, time-slice). Distinguishes from siblings like update-slo and create-slo-correction. Verb+resource+scope is specific.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., update-slo for modifications). Only mentions 'Write-gated' which is behavioral, not usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate a write operation (readOnlyHint=false) but the description lacks details on side effects, required permissions, or state changes. The openWorldHint=true is not explained. Minimal behavioral context beyond the basic purpose.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence front-loads purpose and examples, with no unnecessary words. Could possibly include a usage hint, but remains efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For an 8-parameter tool with no output schema, the description and schema together cover the essential information. Missing guidance on recurrence handling, duration vs end relationship, and potential error cases, but sufficient for basic use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so each parameter has a documented description. The description adds no additional meaning beyond what the schema already provides, meeting the baseline for high coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb ('Create'), resource ('SLO correction'), and purpose ('to exclude a time period from SLO calculations') with specific examples (maintenance, deployments). It distinguishes from sibling tools like 'create-slo' and 'delete-slo-correction'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that conveys the purpose and key filtering capabilities without redundancy. It is front-loaded with the main action and domain, making it efficient for agent scanning.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a search tool with good parameter documentation, the description covers the essential purpose and filter dimensions. However, it lacks information about return values, pagination (limit parameter exists but no explanation of result format), or any behavioral details like sorting default. With no output schema, more context on result structure would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds value by listing example filter fields (service, resource, status, duration) that likely correspond to the query syntax, providing practical guidance beyond the schema. This helps agents construct effective queries.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool searches APM spans/traces for performance analysis, specifying the domain (APM) and the action (search). It differentiates from sibling search tools like search-logs or search-ci-pipelines by focusing on spans/traces. However, it could be more explicit about the resource type (spans/traces) to avoid ambiguity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for APM performance analysis and filtering by common fields, but it does not explicitly state when to use this tool versus alternatives (e.g., search-logs for logs, list-services for services).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate this is a mutation (readOnlyHint=false). The description confirms the update behavior but adds no additional context about side effects, partial updates, or response format. It is adequate but not enriched beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence of 14 words. It is maximally concise with no wasted words, directly communicating the tool's purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite high schema coverage, the description lacks completeness: it does not mention the expected response, error conditions, or that the update is partial. With no output schema, agents have insufficient context for proper invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the baseline is 3. The description adds a concise summary of updatable fields, but omits 'enabled' which is in the schema. It does not provide deeper semantics or constraints beyond what the schema already offers.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Update' and the resource 'RUM retention filter', listing specific fields (name, event type, sample rate, query) that can be updated. This distinguishes it well from sibling tools like create-rum-retention-filter or delete-rum-retention-filter.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusions. Agents must infer usage from the tool name and sibling context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate the tool is not read-only (readOnlyHint=false) and may have side effects (openWorldHint=true). The description adds no further behavioral context, such as authorization requirements or impact on subscribers.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, well-structured sentence of 12 words, front-loaded with the verb 'Update' and no extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the core purpose but lacks context on partial update behavior (e.g., whether omitted fields remain unchanged) and the return value. Given the annotations and schema, it is adequate but not comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema provides clear descriptions for all parameters (100% coverage). The description merely echoes the fields without adding constraints, formats, or examples.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool updates a status page and lists the specific fields (name, domain prefix, subscription settings). It differentiates from sibling tools like update-status-page-component by specifying the top-level resource.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use the tool (when needing to update those fields) but does not explicitly state when not to use it or provide alternatives, such as using update-status-page-component for component-specific changes.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=false and openWorldHint=true. The description adds no further behavioral context beyond stating it updates, such as authorization needs, idempotency, or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that is front-loaded with the key information. It contains no fluff, though it could benefit from slightly more structure (e.g., listing parameters).

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple update tool with 4 parameters and no output schema, the description is adequate but lacks details on return values, error conditions, or what happens if the component does not exist.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the description repeats 'name' and 'position' from the schema. It adds no additional semantic meaning or format details beyond what the schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Update') and resource ('status page component'), and lists the updatable fields ('name or position'). It clearly distinguishes from sibling tools like create-status-page-component and delete-status-page-component.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for updating name or position of a component but provides no explicit guidance on when to use this tool versus alternatives, nor any prerequisites or conditions for use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructiveHint=true and readOnlyHint=false, signaling a mutating operation. The description confirms cancellation but adds no further behavioral context, such as what happens to associated resources or permission requirements. For a destructive tool, this is adequate but not enhanced beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 6 words, front-loaded with the action 'Cancel', and contains zero superfluous information. Every word is necessary, achieving maximum conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema, clear annotations), the description is mostly complete. However, it omits what happens upon success or failure (e.g., confirmation, errors for non-active downtimes), which could be important for the agent. Since no output schema exists, the description should at least hint at the outcome.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a single parameter 'downtimeId' fully described in the schema (type, required, example). The description simply says 'by ID', adding no extra semantic value beyond what the schema provides. Baseline 3 is appropriate for high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Cancel an active downtime by ID' uses a specific verb 'cancel' and clearly identifies the resource 'active downtime' and the identifier 'ID'. It effectively distinguishes this tool from sibling tools like 'create-downtime' and 'list-downtimes', which perform different operations.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus other cancel tools (e.g., cancel-fleet-deployment) or what prerequisites are needed (e.g., obtaining the downtime ID via list-downtimes). It lacks any when-not-to-use or alternative suggestions, leaving the agent without contextual usage cues.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate mutation (readOnlyHint=false). The description confirms creation but adds no extra behavioral details such as permissions or side effects beyond what annotations suggest.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence that is concise and front-loaded, containing no unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Lacks information about return values or confirmation, which would be helpful given no output schema. Adequate for a simple creation tool but incomplete for full context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so parameters are well-documented. The description adds no additional meaning or examples beyond the schema's property descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Create a new Datadog dashboard with widgets' uses a specific verb and resource, clearly distinguishing it from sibling tools like update-dashboard and other create tools for different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance provided on when to use this tool versus alternatives like update-dashboard. Missing context for prerequisites or conditions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate this is a write operation (readOnlyHint=false). The description does not add behavioral traits beyond creating, such as permissions required, side effects, or reversibility. For a mutation tool, more transparency would be helpful.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that effectively front-loads the action and key parameters. Every word is purposeful, with no unnecessary information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the main purpose of creating a status page but does not mention the optional parameter (subscriptionsEnabled) or provide details on the response or post-creation behavior. Given the tool has 5 parameters and no output schema, slightly more context would be beneficial.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%. The description merely repeats 'name, domain prefix, and type' which are already documented in the schema. It adds no new semantic meaning beyond what the schema provides, so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies the action 'Create' and the resource 'status page', and mentions key attributes (name, domain prefix, type). It clearly distinguishes from sibling tools like 'create-status-page-component' or 'update-status-page'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide explicit guidance on when to use this tool versus alternatives, such as when to choose between public/internal type or prerequisites. It is implied for creating a new status page but lacks contextual instructions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate this is a write operation (readOnlyHint=false) with potential side effects (openWorldHint=true). The description mentions scheduling but doesn't elaborate on impacts like display changes or subscriber notifications. It doesn't contradict annotations, but provides only basic behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence that conveys the core function. While concise, it could benefit from a brief note on when to use it. Still, it avoids unnecessary verbosity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 8 parameters and no output schema, the description is too minimal. It doesn't mention what the tool returns (e.g., the created maintenance object ID) or provide behavioral context like notification behavior. This leaves gaps for the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 8 parameters are fully described in the input schema (100% coverage), so the description need not repeat them. The description adds no new information beyond the schema; it only notes 'affected components' which is already covered. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's action ('schedule a maintenance window on a status page') and specifies it involves affected components. This distinguishes it from sibling tools like create-status-page-degradation (for incidents) and update-status-page-maintenance (for updates).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide explicit guidance on when to use this tool versus alternatives. For instance, it doesn't clarify that this is for planned maintenance as opposed to unplanned incidents handled by create-status-page-degradation. Usage is implied but not clearly differentiated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate readOnlyHint=false (write operation) and openWorldHint=true (may create resources beyond input). The description says 'create', which aligns with write, but does not add context about side effects, permissions, or state changes. Since annotations already cover the basic behavioral profile, the description adds minimal value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is concise and front-loaded with the key information. However, it could be slightly expanded to include usage context without becoming verbose. It is efficient but borderline too brief for a complex tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a creation tool with 10 parameters, 4 required, and no output schema, the description is incomplete. It does not mention what happens after creation (e.g., return value like test ID), how to reference the created test, or any follow-up steps. The sibling tools include delete and update, so users would benefit from knowing about the returned identifier.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description mentions subtypes (HTTP, SSL, etc.) but does not add meaning beyond what the schema provides. Each parameter already has descriptive examples in the schema, so the description adds no additional semantic value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (create), the resource (Synthetics API test), and includes examples of subtypes like HTTP, SSL, TCP, etc. This distinguishes it from sibling tools like create-monitor or create-dashboard.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when creating a synthetics test, but it does not provide explicit guidance on when to use this tool over alternatives like create-monitor, nor does it mention any prerequisites or exclusions. The sibling list includes many creation tools, but no differentiation is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already include destructiveHint=true and readOnlyHint=false. The description adds value by specifying that the deletion is 'permanent', reinforcing the destructive nature. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no clutter or repetition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple deletion tool with one parameter and no output schema, the description is adequate. However, it lacks usage guidelines and does not explain return values or side effects beyond what annotations already indicate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a single parameter 'id' documented. The description does not add any extra meaning beyond the schema, so baseline score applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Delete' and the resource 'fleet upgrade schedule', distinguishing it from sibling tools like 'cancel-fleet-deployment' and 'update-fleet-schedule'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines1/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, prerequisites, or when not to use it. Sibling tools include other delete operations, but no differentiation is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructiveHint=true, so the agent knows it's a destructive action. The description adds 'by ID' but does not disclose if deletion is permanent, cascading effects, or error conditions. Minimal added value beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise: one sentence, front-loaded with key action. No wasted words, exactly as needed for a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple delete tool with no output schema, the description could mention expected outcome (e.g., success response, no content) or missing ID behavior. It lacks these details, making it slightly incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers 100% of parameters (incidentId) with description. The tool description merely restates 'by ID', adding no new semantics beyond the schema's field description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'Delete', resource 'Datadog incident', and method 'by ID'. It is specific and distinguishes from sibling tools like update-incident or get-incident.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives, such as the related incident tools (e.g., update-incident, incident-triage-snapshot). No preconditions or when-not-to-use information provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The annotations already indicate destructiveHint=true, so the description's 'Delete' is consistent but adds no further behavioral details such as irreversibility, permissions needed, or side effects. The description does not go beyond what the annotations provide.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that immediately conveys the tool's purpose. There is no redundant or extraneous text.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple delete tool with one parameter, annotations covering destructiveness, and no output schema, the description is sufficiently complete. No additional information is needed.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 100% schema description coverage, the schema already documents the metricId parameter. The description's mention of 'by name' adds minimal additional meaning beyond what the parameter description provides, so a baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (delete), the resource (span-based metric), and the identifier method (by name). It effectively distinguishes this tool from siblings like delete-logs-metric or delete-rum-metric.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives, nor any prerequisites or contexts that would make it appropriate or inappropriate. The description only states what it does.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already label this tool as destructive (destructiveHint=true). The description adds no further behavioral context (e.g., irreversibility, authorization needs, or effects on related data).

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no redundancy, front-loaded with the essential action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple deletion tool, the description is adequate but omits important context like permanence, prerequisites (e.g., pageId must exist), or error conditions. Annotations partially compensate but don't cover all completeness needs.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the description adds no additional meaning beyond what is already in the schema parameter descriptions.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructiveHint=true, so the description doesn't need to repeat that. However, it adds minimal behavioral context (e.g., that it deletes an incident). It does not mention irreversibility, cascading effects, or required permissions. Given annotations, this is adequate but not exceptional.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no unnecessary words. It conveys the core purpose efficiently.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple deletion tool with two parameters and no output schema, the description is minimally adequate. However, it omits details like whether the deletion is permanent or reversible, and any side effects (e.g., cascading to related entities).

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Delete a degradation incident from a status page' uses a specific verb (Delete) and resource (degradation incident), clearly distinguishing it from sibling tools like create-status-page-degradation, get-status-page-degradation, and other delete tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., update-status-page-degradation for modifications) or any prerequisites like ensuring the degradation exists. A simple one-liner does not help an agent decide when to invoke it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already provide readOnlyHint=true and openWorldHint=true. The description adds no extra behavioral context beyond 'get detailed information', such as rate limits, authentication requirements, or what 'detailed' entails. With annotations present, the description should still add value but fails to do so.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 10 words, extremely concise and front-loaded with the core purpose. Every word earns its place with no redundancy or filler.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read tool with 2 parameters (one required) and no output schema, the description is adequate but minimal. It does not explain what information is returned (e.g., full incident object) or that extractFields can reduce response size. With sibling tools like get-incidents and search-incidents, the context is sufficient but could be more complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with detailed descriptions for both parameters (incidentId and extractFields). The tool description only mentions 'by ID', adding minimal value beyond the schema. Baseline is 3 due to high coverage, and the description does not improve parameter understanding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the specific verb 'Get' and resource 'detailed information about a specific Datadog incident by ID'. It clearly differentiates from sibling tools like get-incidents (which lists incidents) and search-incidents (which searches), as it focuses on a single incident retrieved by ID.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies that this tool should be used when you have an incident ID and need detailed information, but it does not explicitly state when to avoid using it or mention alternatives like search-incidents for finding incidents by other criteria. The guidance is adequate but minimal.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description adds minimal behavioral context beyond stating 'detailed information'. No contradictions, but no additional transparency about response structure or edge cases.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with no wasted words, front-loaded with the action and target. Efficient for a simple retrieval tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, the description does not elaborate on what 'detailed information' includes or any error handling. Partially complete but sufficient for a straightforward get-by-ID operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter description 'The device ID'. The description only restates 'by ID', adding no new meaning. Baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves detailed information for a specific network device by ID, distinguishing it from sibling tools like list-network-devices which list devices.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives (e.g., list-network-devices) or exclusion criteria. The agent must infer usage from the name and schema.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description adds little beyond stating it's a get operation. It does not contradict annotations, but it does not enrich behavioral understanding.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no unnecessary words. It efficiently conveys the tool's purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is adequate for a simple read tool with annotations, but it does not explain what a service definition contains or provide guidance on obtaining the entity ID, which could be helpful.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and already includes a description for 'entityId'. The description merely references 'by entity ID' without adding new meaning, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'service definition', and the lookup method 'by entity ID'. It is specific and distinguishes this tool from other get tools in the sibling list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, context, or exclusions, which is a significant gap.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already provide readOnlyHint=true and openWorldHint=true, so the safety profile is clear. The description adds no further behavioral context beyond stating it gets 'detailed information'. With annotations covering the core behavioral traits, the description is adequate but not enriched.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with 8 words. It is front-loaded, contains no filler, and every word contributes to understanding the tool's purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    While the tool is simple (get by two IDs), the description does not explain what 'detailed information' entails, and there is no output schema. For a read tool, lack of return structure hints reduces completeness. It is minimally complete but could be improved by describing the output fields or format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already describes both parameters fully (pageId: 'The status page ID', degradationId: 'The degradation ID') with 100% coverage. The description adds no additional meaning beyond the schema, meeting the baseline for coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's function: 'Get detailed information about a specific degradation incident'. It uses a specific verb ('get') and resource ('degradation incident'), which distinguishes it from sibling tools like 'list-status-page-degradations' (list vs. specific) and 'get-status-page' (different resource).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites, limitations, or when not to use it. It simply states what the tool does without contextualizing its use case among siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Description adds clarification 'monitor mute periods' but does not elaborate on behavioral traits beyond annotations (readOnlyHint, openWorldHint). No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single concise sentence with front-loaded key information. No superfluous content.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema and description lacks details about return format, pagination, or example usage. Adequate but minimal for a simple list tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers all 4 parameters with descriptions (100% coverage). Tool description adds no extra information about parameters; baseline score applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'List scheduled downtimes (monitor mute periods)' with specific verb and resource, distinguishing from sibling tools like create-downtime or cancel-downtime.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance provided on when to use this tool vs alternatives (e.g., get-monitor, list-slos). Missing context for selection among many list tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=false and openWorldHint=true. Description adds context about accessibility scope (public internet or internal org), which is useful. However, it does not disclose other traits like idempotency, required permissions, or side effects beyond what annotations imply.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no superfluous words. Every part earns its place, conveying the core action and scope efficiently.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple one-parameter tool with no output schema, the description covers the basic purpose and accessibility scope. However, it lacks context on prerequisites (e.g., page must exist) and expected behavior after publishing. Minimal but adequate given low complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% with a clear description for pageId. The tool description does not add any additional meaning beyond what the schema already provides, so baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'Publish' and resource 'status page', and specifies the outcome: make it accessible to public internet or internal org. This distinguishes it from sibling tools like 'unpublish-status-page' or 'update-status-page'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., page must exist), nor does it indicate that it should be used after creation or to make a page live. Lack of when-to-use and when-not-to-use information.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint and openWorldHint, which cover key behavioral aspects. The description adds minimal context (mobile/web app source) but does not disclose additional traits like query syntax details, pagination, or rate limits. With annotations present, the description contributes moderately.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence that efficiently conveys the purpose and scope. Every word is necessary, and there is no redundancy or filler.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 6 well-documented parameters and annotations, the description is adequate but not fully complete. It lacks details on result format, pagination, or query syntax, and does not situate itself among similar search tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The tool description does not add any parameter-specific information beyond what is in the schema. The schema already provides detailed examples and constraints for each parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the verb 'Search', the resource 'Real User Monitoring events', and specifies event types (sessions, views, errors, actions) and source (mobile/web apps). This clearly differentiates from sibling tools like search-logs or list-rum-applications.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention when not to use it or point to sibling tools for related tasks like searching logs or aggregating RUM data.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate readOnlyHint=false and openWorldHint=true, but the description does not elaborate on side effects, partial updates, or required permissions. It adds basic context beyond annotations but is not thorough.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations correctly indicate a non-read-only operation, and the description's 'update' aligns. The term 'existing' implies the application must exist, but no details on side effects, permissions, or idempotency are provided. Beyond the schema, no additional behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single 8-word sentence that is perfectly front-loaded with the action and resource. No redundant or extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description sufficiently covers the action and inputs (with schema support), but lacks any mention of return values or error behavior. Given no output schema, the agent is left to infer typical update response patterns.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with adequate per-parameter descriptions. The description's mention of 'name or type' summarizes the optional fields but adds no new semantic meaning beyond what the schema already provides.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Update'), the resource ('existing RUM application'), and the specific fields that can be modified ('name or type'). It directly distinguishes from sibling tools like create-rum-application and delete-rum-application.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., create vs update). No mention of prerequisites or context where this should not be used. The description is purely functional.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate write operation (readOnlyHint=false) and open world (openWorldHint=true). The description adds the specific fields that can be updated, offering some behavioral context, but does not disclose error handling, idempotency, or side effects implied by openWorldHint.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no wasted words, front-loading the verb and resource. It efficiently conveys the core action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 4 parameters, no output schema, and annotations provided, the description adequately states the action. However, it does not address the openWorldHint implications or mention that percentile updates are only for distribution metrics (though covered in the parameter description). It is sufficient but not enhanced.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with informative parameter descriptions. The tool description summarizes the parameter categories (filter, group-by, percentile) but adds no new meaning beyond what the schema already provides. Baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Update' and the resource 'span-based metric', and lists the specific updatable settings (filter, group-by, percentile). This distinguishes it from sibling tools like create-spans-metric, delete-spans-metric, and get-spans-metric.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate a write operation (readOnlyHint=false), consistent with description. However, description adds no behavioral details beyond creating a downtime, such as side effects, idempotency, or rate limits. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence, front-loaded with action, no wasted words. Could be slightly more structured to include usage context, but highly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Lacks mention of scheduling (start/end), indefinite downtimes, and return behavior (no output schema). Adequate for basic understanding but incomplete for nuanced use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter descriptions. The tool description summarizes the three mute approaches (scope, ID, tags) but adds no new meaning beyond what the schema provides. Baseline 3 is appropriate.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (create a downtime), the resource (downtime), and mechanism (mute monitors by scope, monitor ID, or tags). It distinguishes from siblings like cancel-downtime, list-downtimes, and mute-monitor.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Implied usage from description but no explicit when-to-use, when-not-to-use, or comparisons with alternatives (e.g., mute-monitor). No exclusions or prerequisites mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate this is a write operation (readOnlyHint=false) and partially open (openWorldHint=true). The description adds no further behavioral traits such as required permissions, rate limits, or what happens on failure. For a mutation tool without output schema, more disclosure is expected.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no wasted words. It efficiently conveys the core purpose and key inputs.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (3 params, no output schema, no nested objects), the description is mostly complete. It covers the creation action and required inputs, though it does not mention return value or side effects. Still, it is sufficient for basic guidance.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema already documents all parameters with descriptions. The description's mention of 'title and customer impact info' adds no new meaning beyond what the schema provides. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Create a new Datadog incident' specifying the verb and resource. It also mentions key inputs (title, customer impact info), which differentiates it from sibling tools like update-incident or delete-incident.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for creating incidents but does not provide explicit guidance on when to use this tool versus alternatives like search-incidents or incident-triage-snapshot. No exclusions or context for selection given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate readOnlyHint=false (mutates) and openWorldHint=true. The description adds operational context (filters, group-by) but does not detail side effects, permissions, or lifecycle. Consistent with annotations, no contradiction.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single concise sentence that is front-loaded with key action and resource. No wasted words, appropriate length.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema, and the description does not explain what the created metric does, where it appears, or how to use it later. Lacks completeness for a creation tool, especially with 8 parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the description adds little beyond summarizing parameter options (e.g., 'count or distribution'). It does not provide additional semantics not already in the schema. Baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'create', the resource 'metric based on RUM data', and specifies the capabilities (count or distribution, with filters and group-by). This distinguishes it from siblings like 'create-logs-metric'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for creating RUM metrics but lacks explicit guidance on when to use this tool versus other metric creation tools or when to choose count vs distribution. No when-not-to-use or alternative suggestions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description matches the annotations (destructiveHint=true, readOnlyHint=false) by stating 'Delete'. However, it adds no additional behavioral details such as whether deletion is irreversible, requires special permissions, or triggers side effects. With annotations already providing the destructive nature, a score of 3 is appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 6 words, perfectly front-loaded with the action and resource. Every word serves a purpose with no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple destructive action with one parameter and no output schema, the description is nearly complete. It could optionally note that deletion is irreversible, but the destructiveHint annotation already conveys that. The description does not repeat what's in structured fields, making it efficiently complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'id' is fully described in the schema as 'RUM application ID to delete'. The description's phrase 'by ID' adds no new meaning beyond the schema, which already achieves 100% coverage. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb (delete), resource (RUM application), and identifier method (by ID). It effectively distinguishes from sibling tools like create-rum-application, update-rum-application, and get-rum-application, as well as other delete tools for different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives no guidance on when to use this tool versus alternatives, nor does it warn about destructive consequences or prerequisites beyond the schema. Despite the destructiveHint annotation, the description does not explicitly state 'only use if you are sure' or compare with update-rum-application.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The annotations already indicate destructiveHint=true and readOnlyHint=false. The description adds no additional behavioral context beyond the identifier method. It does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 6 words, conveying the essential information without any fluff. It is perfectly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the annotations (destructiveHint=true) and simple param schema, the description is nearly complete. However, adding a note about irreversibility or required permissions would strengthen it.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, and both parameters have clear descriptions in the schema. The description 'by ID' adds no extra meaning beyond what the schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Delete a RUM retention filter by ID', specifying the action (delete), resource (RUM retention filter), and identifier (ID). This distinguishes it from sibling tools like create, update, get, and list.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as prerequisites, irreversibility, or when not to use it. It fails to aid the agent in decision-making.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructiveHint=true and readOnlyHint=false. The description adds 'delete' which aligns with the destructive nature, but does not provide additional behavioral context like irreversibility or required permissions beyond what annotations offer.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is concise and front-loaded. No extraneous information or fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity of the tool (one parameter, no nested schemas, destructive annotations), the description adequately covers the action. However, it could mention effects or success/failure behavior for completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'suppressionId' is fully described in the schema (100% coverage). The description only repeats 'by ID' without adding new meaning or usage details beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Delete a security monitoring suppression rule by ID' uses a specific verb ('Delete') and a specific resource ('security monitoring suppression rule'), and clearly distinguishes it from sibling tools like create, get, and list security suppressions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as conditions for deletion or prerequisites. It only states the action, missing context for proper usage.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description only restates the read nature of the tool, which is already indicated by the readOnlyHint annotation. It adds no additional behavioral context beyond what annotations provide.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no unnecessary information. It is well-structured and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is brief but sufficient for a simple get operation. It does not specify what 'detailed information' includes, but the output schema is not required, and the annotations provide safety context. Slightly incomplete but adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already describes the filterId parameter. The description does not add any additional meaning or context about the parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'Get detailed information about a specific APM retention filter', using a specific verb and resource. It distinguishes from sibling tools like create, delete, update, and list variants.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No when-to-use or when-not-to-use guidance is provided. The description does not mention alternatives such as 'list-apm-retention-filters' for retrieving all filters.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=true and openWorldHint=true, so the description does not need to restate safety. It adds limited context by saying 'detailed information', but does not specify what fields are returned or any other behavioral traits beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no unnecessary words. It is appropriately sized and front-loaded with the key action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, read-only, annotations present), the description is mostly adequate. However, it does not mention that the response is a full case object, which would be helpful since there is no output schema. Sibling tools provide context, so the gap is minor.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already describes caseId as a UUID with 100% coverage. The description adds no new meaning beyond 'by ID', so it meets the baseline of 3 for a fully documented schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves detailed information for a specific case by ID. It uses a specific verb ('Get'), resource ('case'), and identifier ('by ID'), distinguishing it from siblings like list-cases (which returns multiple cases) and create-case (which creates).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as list-cases or update-case-status. The agent must infer usage from the tool name and context, which may lead to incorrect selection.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to restate safety. It adds no behavioral context beyond the schema, but does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description consists of a single, essential sentence that conveys the core purpose without any redundant information. It is optimally concise and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with no output schema, the description and parameter schema together are largely complete. Pagination is handled by parameters, and the description implies all dashboards are returned. Minor gap: no mention of default ordering or what happens with large result sets.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, with each parameter already described in the input schema. The tool description adds no additional meaning beyond what the schema provides, meriting a baseline score of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all Datadog dashboards' uses a specific verb ('List') and resource ('Datadog dashboards'), clearly distinguishing it from sibling tools like 'get-dashboard' (singular) which retrieves a specific dashboard.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as 'get-dashboard' for a single dashboard or 'search-audit-logs' for historical access. No prerequisites or exclusions are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, so the description's statement 'Get' aligns with read-only behavior. The description adds context about filtering but does not disclose additional behavioral traits such as pagination (though a page parameter exists) or rate limits. With annotations covering the core behavior, the description adds minor value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that front-loads the main purpose and optional filters. Every word is necessary, and there is no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has 7 parameters, no output schema, and annotations present, the description covers the main retrieval purpose. However, it does not mention pagination behavior, return format, or limits, which would improve completeness for an agent. It is adequate but not thorough.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description highlights filters (priority, source, tags) that map to parameters, but does not add meaning beyond what the schema already provides for each parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'Datadog events', and the scope 'within a time range', with optional filters. Among sibling tools, there is no competing event retrieval tool, and it distinguishes from 'post-event' which creates events.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for retrieving events within a time range with optional filters, but it does not explicitly state when to use this tool versus alternatives like 'post-event' for creation or other search tools. The context is clear enough for an AI agent to infer, but lacks explicit guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint and openWorldHint. The description adds that it returns totals and can be filtered by 'from' time. However, it does not disclose output format, behavior with no hosts, or error conditions. Some behavioral context is added but not in depth.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence, nine words, no redundancy. Information is front-loaded. Could be slightly more structured but is appropriately concise for a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one optional parameter and no output schema, the description is adequate but incomplete. It does not specify the return format (e.g., single number or object), which the agent would need to interpret results. With no output schema, the description should clarify output structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with the 'from' parameter described. The description mentions time-based totals but does not add meaning beyond the schema's parameter description. Baseline of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the function: 'Get total number of active and up hosts'. It uses a specific verb and resource, distinguishing it from sibling tools like 'list-hosts' which likely return detailed host lists.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Usage context is implied (aggregate vs. list), but no explicit when-to-use or when-not-to-use guidance is provided. The description does not contrast with sibling tools like 'list-hosts' or 'get-metrics'.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, covering safety and result variability. The description adds that it returns type, unit, and description, providing context about the output. However, it does not disclose potential issues like missing metadata for some metrics or authentication requirements. With annotations handling basic traits, the description adds moderate value beyond structured fields.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, 10 words, front-loaded with verb and resource. No filler words. Perfectly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Simple tool with one parameter and no output schema. Description lists the three key metadata fields, which is sufficient for most use cases. Could optionally mention that the metadata might be empty or contain additional fields, but not necessary for typical usage. Completeness is high for this complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 100% coverage: metricName is described as 'Full metric name. Example: system.cpu.user'. The description does not add new semantic meaning beyond the schema. Baseline 3 per guidelines for high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states verb 'get', resource 'metadata for a specific Datadog metric', and specifies what metadata is included (type, unit, description). It distinguishes from sibling tools like get-metrics which list metrics, and list-active-metrics.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool vs alternatives like get-metrics or list-active-metrics. The description does not mention prerequisites (e.g., knowing the metric name) or scenarios where this tool is preferred. Sibling tools provide similar functionality but no comparative advice is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, so the description does not need to restate safety. However, it adds no behavioral context beyond stating 'detailed information', such as what fields are included, potential rate limits, or any side effects (openWorldHint suggests external influences). The description adds limited value over annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that efficiently conveys the tool's primary function without unnecessary words or repetition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a straightforward fetch-by-ID tool with fully described parameters, the description is fairly complete. It could mention expected response structure or error codes, but given no output schema, it is sufficient to guide the agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with each parameter having a description. The tool description adds no additional meaning beyond the schema. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the specific verb 'Get' and resource 'detailed information about a specific Datadog monitor by ID', clearly indicating that this tool retrieves details for a single monitor. It is distinct from sibling tools like get-monitors (list) and other get-* tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as get-monitors for listing, update-monitor for modifications, or delete-monitor for removal. No when-not-to-use or explicit context is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to repeat read-only behavior. However, it adds limited behavioral context beyond annotations, only mentioning that results include layers and team information. No disclosure of auth requirements, rate limits, or handling of invalid IDs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no unnecessary words. It efficiently conveys the core purpose and scope.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read operation with two parameters and comprehensive annotations, the description is fairly complete. It mentions key return elements (layers and team info). However, it lacks details on error states or the structure of the returned object, which is partially mitigated by the lack of output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for both parameters. The description hints at what 'include' may do ('with layers and team information') but does not add significant meaning beyond what the schema provides (e.g., comma-separated relationships and example). Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Get), the resource (on-call schedule by ID), and the included details (layers and team information). It differentiates from sibling tools like get-team-oncall which gets on-call for a team rather than by schedule ID.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., get-team-oncall or other schedule-related tools). The description does not specify prerequisites, when not to use it, or provide examples of appropriate context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint and openWorldHint, so the description's 'Get detailed information' is consistent but adds no behavioral insight beyond what is already provided.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, efficient sentence with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    There is no output schema, and the description does not specify what 'detailed information' includes, leaving the agent uncertain about the tool's return structure.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for the single parameter 'ruleId', which the schema already documents. The description does not add any additional meaning or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'specific security monitoring detection rule', distinguishing it from sibling tools like 'list-security-rules' which lists all rules.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for retrieving a single rule but does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds no further behavioral context (e.g., error handling, permissions). No contradiction, but minimal added value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with key action. No unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple get-by-ID tool with one required parameter and no output schema, the description is adequate. It covers the core purpose but lacks hints about return format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description simply says 'by ID' without adding meaning beyond the schema's parameter description.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'aggregate' and the resource 'CI/CD pipeline data', specifying 'statistical computations and grouping'. This distinguishes it from sibling tools like aggregate-ci-tests or aggregate-logs, which target different data types.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not explicitly state when to use this tool versus alternatives. The context of sibling names implies it's for pipeline aggregations, but no when-not or alternative guidance is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description aligns with the readOnlyHint and openWorldHint annotations by describing aggregation, which is a read operation. However, it does not disclose any behavioral traits beyond what the annotations already provide, such as query limits or data freshness.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, well-structured sentence that front-loads the key verb and resource. Every word contributes to conveying the tool's purpose without unnecessary detail.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the aggregation types and grouping, but lacks any mention of the return format (e.g., time series or table) or pagination behavior. Given the absence of an output schema, this information would be valuable for agent understanding.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% description coverage for all parameters. The description's mention of 'count, avg, sum, percentiles and grouping' provides a high-level summary of the aggregation enum and groupBy parameter but does not add substantial new meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the verb 'Aggregate', the resource 'Datadog logs', and the types of computations ('count, avg, sum, percentiles') and grouping. It clearly distinguishes from sibling tools like 'search-logs' and 'aggregate-ci-pipelines'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for aggregated statistical queries via the words 'statistical computations' and 'grouping', but it does not explicitly state when to use this tool over alternatives like 'search-logs' or when not to use it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare destructiveHint: true, indicating the destructive nature. The description adds 'by name' but does not elaborate on behavioral traits beyond what annotations provide. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity, the description is adequate but lacks details on return values or result structure (no output schema). With pagination parameters, some guidance on result ordering or empty results would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for the two parameters (pageSize, pageNumber), and their descriptions are already in the schema. The description adds no further meaning beyond the schema, so a baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List' and the resource 'all Synthetics monitoring tests' with specific types (API, Browser, Mobile), distinguishing it from sibling tools like get-synthetics-result or list-slos.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for listing synthetics tests but does not explicitly state when to use this tool versus alternatives or provide exclusions. No guidance on pagination or default ordering is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=false (write operation), which the description aligns with by stating 'mute'. No additional behavioral context is provided, such as side effects, reversibility, or required permissions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence (12 words) with no fluff. Front-loaded with key action and resource. Efficiently communicates the core functionality.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema and minimal annotations, the description does not explain the return value, side effects (e.g., notifications suppressed), or how to unmute. Useful but leaves gaps for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and each parameter has a description. The description adds minimal value beyond summarizing that scope is for filtering and end is optional, but does not add new semantic meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'mute', the resource 'Datadog monitor', and adds clarifying context 'silence notifications for a scope and optional duration'. This distinguishes it from sibling tools like create-downtime or cancel-downtime.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for silencing monitor notifications with scope/duration, but does not explicitly state when to use this tool vs alternatives like create-downtime or how to revert. No when-not-to-use guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description mentions 'query filtering' but does not add significant behavioral details beyond what annotations (readOnlyHint, openWorldHint) already provide. It does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All four parameters have schema descriptions, resulting in 100% schema coverage. The description lists the same fields (filter, group-by, percentile) without adding new meaning or context beyond what the schema provides, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'update', the resource 'rum-based metric', and the specific settings that can be changed: filter, group-by, or percentile. This distinguishes it from sibling tools like create-rum-metric or delete-rum-metric.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for modifying an existing metric's configuration, but does not explicitly state when to use this tool versus alternatives, nor does it provide prerequisites or conditions for use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate a write operation (readOnlyHint: false). The description confirms this by stating 'Update'. However, it does not disclose additional behavioral traits such as side effects, required permissions, or rate limits. With annotations present, the bar is lower, but the description adds no extra context beyond the schema fields.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a mutation tool with no output schema and 100% schema coverage, the description is mostly complete. However, it could be improved by briefly mentioning the expected output or any asynchronous behavior, but it adequately conveys the core functionality.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, meaning all parameters are already described in the schema. The description does not add any extra meaning or context beyond what the schema provides, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Create a deployment' and specifies the resource 'fleet deployment' and the purpose 'to apply configuration changes to hosts matching a filter'. It distinguishes this tool from its sibling 'create-fleet-deployment-upgrade' by focusing on configuration changes rather than upgrades.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is for applying configuration changes to filtered hosts, but does not explicitly state when to use it versus alternatives like 'create-fleet-deployment-upgrade'. No when-not or exclusion criteria are provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description adds context that this is a write operation creating a deployment for upgrades, which aligns with the 'readOnlyHint' of false. However, it does not elaborate on side effects (e.g., whether it triggers immediately, if it can be rolled back, or if it affects existing deployments). The 'openWorldHint' is true, but the description provides no additional behavioral insight beyond the tool's purpose.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Given that the tool has only two parameters, no output schema, and annotations are provided, the description covers the essential purpose and scope. It lacks details about return values or asynchronous behavior, but for a create action, the context is largely sufficient for an agent to understand when and how to use it.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already describes both parameters (filterQuery and targetPackages) thoroughly, achieving 100% coverage. The tool-level description does not add any new meaning or constraints beyond summarizing that the deployment targets 'matching hosts', which is already captured in the schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the verb 'Create', the resource 'deployment', and the specific intent 'to upgrade Datadog Agent packages on matching hosts'. This clearly distinguishes it from the sibling tool 'create-fleet-deployment-configure', which presumably handles configuration changes rather than upgrades.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool should be used when upgrading agent packages on specific hosts, but it does not explicitly state when to use it versus alternatives like 'create-fleet-deployment-configure'. There is no mention of prerequisites, when not to use it, or how it differs from other create tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations provide basic safety profile (non-read-only, open world). The description adds no further behavioral details such as side effects, permissions, or whether the metric persists. With openWorldHint=true, more context would be helpful.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the description does not need to repeat that. It adds 'with their roles' as return context but does not describe pagination, rate limits, or potential empty results. The description provides some additional context beyond annotations but is not rich.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that conveys the tool's purpose without any wasted words. It is front-loaded and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (get members with pagination) and the schema covering parameters fully, the description is nearly complete. It could mention pagination behavior or response format, but for a straightforward retrieval operation, it suffices.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all three parameters. The tool description does not add any extra meaning beyond what the schema provides, meeting the baseline of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves members of a Datadog team and includes their roles. It uses a specific verb ('Get') and resource ('members of a team'), distinguishing it from sibling tools like 'get-team' (which gets team info) and 'list-teams' (which lists all teams).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for fetching team members, but it does not explicitly state when to use this tool versus alternatives, nor does it mention any prerequisites or when not to use it. The context is clear but lacks explicit guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already provide readOnlyHint=true, indicating no state modification. The description adds no further behavioral details (e.g., returns all filters, no pagination). It does not contradict annotations, but misses an opportunity to disclose traits like list format or ordering.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no fluff. Every word adds value. Front-loaded with action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with no parameters and no output schema, the description is mostly complete. It could mention that the output is a list of filter objects, but the purpose is clear enough.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has zero parameters, so schema coverage is 100%. Baseline for 0 params is 4. Description adds no parameter info, but none is needed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'List' and the resource 'APM retention filters', and explains their purpose ('control which traces are retained for search'). This distinguishes it from sibling tools like create/get/delete/update variants.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Description clearly states 'Get a specific component by ID from a status page', specifying the verb (Get), resource (component), and identifier (by ID). It distinguishes from sibling tools like list-status-page-components (list all) and get-status-page (get page).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool vs alternatives (e.g., list-status-page-components). Usage is implied (when you have a component ID), but no when-not-to-use or comparison provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already state readOnlyHint=true and openWorldHint=true, covering safety and result volatility. The description adds that each metric includes its definition, which is useful behavior context. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 8 words, directly stating the purpose. No unnecessary information, front-loaded verb and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with no parameters and no output schema, the description is complete: it specifies the resource type (log-based metrics) and what is returned (definitions). Annotations handle safety and open-world behavior.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has no parameters, so schema description coverage is trivially 100%. The description correctly adds no parameter info, as none exist. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists all configured log-based metrics with their definitions. It uses a specific verb 'list' and resource 'log-based metrics', distinguishing it from sibling tools like 'get-logs-metric' (single) and 'list-active-metrics' (all metrics).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the tool is used to retrieve log-based metrics but provides no explicit guidance on when to use it vs alternatives like 'list-metric-tags' or 'get-logs-metric'. No when-not-to-use or prerequisite information is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint and openWorldHint, so the description need not repeat. It adds the behavioral trait of search/tag filtering, but does not detail pagination or data scope, which is acceptable given annotation coverage.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that efficiently conveys the core function and key features without extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without an output schema, the description does not clarify what the response contains (e.g., process details). It covers input parameters but omits output structure, which is needed for a complete understanding.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so description adds minimal value beyond the schema. It references search and tags but does not elaborate on other parameters like from, to, pageSize, or pageCursor.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists running processes across infrastructure with search and tag filtering, differentiating from sibling tools like list-hosts or list-containers.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives. The description implies usage for listing processes with filters, but does not mention when not to use it or compare to other list tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, indicating safe, read-only behavior with potentially dynamic results. The description adds no additional behavioral context beyond restating the purpose, which is acceptable but not enhancing.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, directly stating the tool's purpose without any extraneous information. It is perfectly concise and front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has no parameters and no output schema, the description fully explains its functionality. The context (listing all configured span-based metrics with definitions) is complete for an agent to understand what the tool does.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has zero parameters, and schema description coverage is 100% (trivially). With no parameters, the description does not need to explain parameter semantics; baseline 4 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all configured span-based metrics with their definitions' clearly states a specific verb ('List') and resource ('span-based metrics'), and it distinguishes from sibling tools like 'get-spans-metric' (which retrieves a single metric) and 'create-spans-metric' (which creates a metric).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives (e.g., get-spans-metric for a specific metric). It only states what the tool does, not the context for its use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true. The description confirms read-only listing but adds no further behavioral context (e.g., rate limits, output format). With annotations present, the description provides minimal added value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, front-loaded sentence with no unnecessary words. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description does not explain the response structure (e.g., an array of status pages). This is a minor gap for an agent needing to parse results. However, many list tools follow a consistent pattern.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear parameter descriptions. The tool description does not add any semantic information beyond what the schema already provides, meeting the baseline.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description specifies the verb 'List' and the resource 'all Datadog status pages for the organization', clearly distinguishing it from sibling tools like 'get-status-page' (single retrieval) or create/delete variants.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage is for fetching the full list of status pages, but lacks explicit guidance on when to use this vs alternatives such as 'get-status-page' or pagination handling. Still, the context is clear given sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate non-read-only and open-world, so description consistency is fine. Adds that it creates a deployment, but doesn't mention side effects, authorization needs, or error conditions. Adequate with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One sentence of 10 words, front-loaded with action and resource, no wasted text. Exceptionally concise for the information provided.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (1 param, no output schema, annotations present), the description fully covers purpose and outcome, making it complete for its complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Single parameter 'id' with schema description 'The schedule ID to trigger manually'. Schema coverage is 100%, and description doesn't add extra meaning beyond the schema, resulting in baseline score.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'trigger', the resource 'fleet schedule', and the outcome 'immediately create a deployment'. It distinguishes from siblings like 'create-fleet-schedule' (creates a schedule) and 'get-fleet-schedule' (retrieves).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Implies usage when you want to manually trigger a schedule to create a deployment, but no explicit when-not or alternatives mentioned. Context from siblings helps somewhat, but lacks direct guidance.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already mark this as destructive (destructiveHint=true). The description adds behavioral context by stating the specific outcome: removing public/internal access. It does not contradict annotations and provides useful beyond-annotation detail about what gets affected.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence with no unnecessary words. It is front-loaded with the key action and resource. Every word earned its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple one-parameter tool with annotations, the description is adequate but could be more complete by clarifying the state after unpublishing (e.g., page remains but inaccessible) or mentioning reversibility (it can be republished). Lacks these details.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for the single parameter 'pageId'. The tool description adds no additional parameter information beyond what the schema already provides, so baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action 'Unpublish', the resource 'status page', and the effect 'to remove public/internal access'. It distinguishes from sibling tools like 'publish-status-page' (opposite) and 'delete-status-page' (permanent deletion).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage (when you want to remove access), but lacks explicit guidance on when to use vs alternatives (e.g., 'delete-status-page' for permanent deletion) or prerequisites (page must be published). It does not mention when not to use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description adds behavioral context beyond annotations by specifying that it cancels an 'active' deployment and 'stop[s] pending operations', which is useful for understanding side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint and openWorldHint, so the description only adds 'for deployment' context. It does not disclose pagination, filtering, or result set behavior beyond what annotations imply.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single front-loaded sentence with no unnecessary words. Perfectly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple zero-parameter list tool with annotations covering safety, the description is mostly adequate. However, it lacks any hint about the output structure (e.g., returns a list of version strings) which would be helpful since no output schema exists.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    There are zero parameters, so schema coverage is 100%. Baseline for no parameters is 4, and the description adds no parameter-related value, but none is needed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'List all available Datadog Agent versions for deployment' clearly states the verb (list), resource (Datadog Agent versions), and context (for deployment). It distinguishes from sibling tools like list-fleet-agents (lists agents) and list-fleet-deployments (lists deployments).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for deployment planning but does not explicitly state when to use this tool versus alternatives like list-fleet-agents or list-fleet-deployments. No exclusions or prerequisites are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is clear. The description adds context about the content (exclusions from SLO calculations) but does not elaborate on pagination, ordering, or potential side effects. It adds some value beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, front-loaded sentence with a parenthetical explanation. Every word serves a purpose; no redundant information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with pagination parameters and annotations covering safety, the description is mostly adequate. It could be improved by mentioning what fields are in each correction object, but the absence of an output schema and the tool's simplicity make it sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage for both parameters (offset and limit) with clear descriptions. The tool description adds no additional meaning or constraints beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists SLO status corrections and explains what those are (maintenance windows, deployments excluded from SLO calculations). It distinguishes from siblings like list-slos (SLOs, not corrections) and get-slo-correction (single item).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use when you need a list of SLO corrections rather than a single correction (get-slo-correction) or a list of SLOs (list-slos). However, it does not explicitly state when to use or when to avoid using this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity and the comprehensive schema descriptions, the description is mostly complete. However, it does not mention the return value or response format, which could be helpful as there is no output schema. Other than that, the context for using the tool is sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with all 8 parameters having descriptions in the input schema. The description adds no additional semantic information beyond what is already in the schema, which is adequate but not exceptional. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Post a custom event to Datadog', specifying the verb 'post' and the resource 'custom event'. It further distinguishes the tool's capability by noting support for markdown and @mentions. This clarity sets it apart from sibling tools like get-events or other creation tools for different resources.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide explicit guidance on when to use this tool versus alternatives. While the context of 'custom event' implies it's for arbitrary event creation, there is no mention of when not to use it or what alternatives exist (e.g., for system events). The guidance is only implicit.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Explicitly states 'Fetches current SLO first to merge unspecified fields' and 'Write-gated', which are not in annotations. Annotations show readOnlyHint=false (consistent). Adds significant behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with parameter descriptions. The description adds no extra semantic value beyond the schema, such as elaborating on extractFields usage or historyDays default. Baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool aggregates SLO health data, including config, history, corrections, and linked monitor states, computing errorBudgetRemainingPct and status. It distinguishes from siblings like get-slo, get-slo-history, and list-slo-corrections by noting it replaces 3-5 round-trips.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly compares to individual tools, stating it replaces multiple round-trips and uses Promise.allSettled for partial failures. It implies when to use (for a comprehensive snapshot) but does not explicitly state when not to use or provide alternative tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=true and openWorldHint=true. The description adds that it returns tool names and descriptions covering all 158+ tools, which is useful behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences: first states purpose and output, second gives usage guidance. No wasted words, front-loaded with action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Without an output schema, the description adequately explains return value (matching tool names + descriptions). Given low complexity and annotations covering safety, this is complete for agent decision-making.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so all parameters already have descriptions. The description does not add extra parameter-level details beyond what is in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it discovers available tools via natural language query and returns tool names and descriptions. It distinguishes itself from sibling tools by being the tool to find the right tool before calling specific ones.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly advises 'Use this first to navigate the surface efficiently — call this, then call the specific tool you need.' This provides clear when-to-use guidance and implies not to use when already knowing the target tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description goes beyond annotations by disclosing use of Promise.allSettled and caveats[] array for per-fetcher failures. Annotations (readOnlyHint=true, openWorldHint=true) are consistent with read-only aggregate behavior, and the description adds valuable implementation detail.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single paragraph but packs all essential information without redundancy. It is front-loaded with purpose and lists components. Could benefit from slight structuring (e.g., bullet points), but it is concise and every sentence earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity and no output schema, the description provides adequate information: response structure includes incident metadata, related events, similar incidents, log-spike heuristic, and summary block with severity/duration/spike flag. It also explains fallback behavior. Slightly more detail on exact fields would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 6 parameters have schema descriptions, but the tool description adds critical context: derivation of service from incident fields, default values for booleans, max for lookback, and suggestion for finding incidentId. This adds significant meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool aggregates multiple operations into one call, listing specific components (incident metadata, related events, similar incidents, log spike) and naming the underlying operations. It distinguishes from siblings like get-incident or search-incidents by being a composite.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly states it replaces the 5-step `triage-incident` orchestration, giving clear context for when to use it. However, it does not provide explicit when-not-to-use scenarios or alternative sibling tools for specific needs.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
