Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v1.7.0

  • Disambiguation4/5

    Most tools have distinct resource-action pairs, but there is potential confusion between `project_access_list_*` and legacy `project_whitelist_*` tools, as they serve similar purposes. Descriptions help differentiate them, but an agent might still pick the wrong one.

    Naming Consistency5/5

    All tools follow a consistent `resource_verb` naming pattern in snake_case (e.g., `cluster_create`, `atlas_search_get_all`). No mixed conventions or ambiguous verb styles, making the pattern predictable.

    Tool Count3/5

    76 tools is quite high, covering a broad API surface. While each tool has a specific purpose, the sheer number can overwhelm agents and may include redundant or overly granular operations (e.g., legacy whitelist vs. access list).

    Completeness4/5

    The tool set covers major CRUD operations for clusters, users, backups, search indexes, projects, and organizations. Minor gaps exist, such as no alert update/delete and limited team management, but core workflows are supported.

  • Average 2.9/5 across 76 of 76 tools scored. Lowest: 1.3/5.

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

  • Behavior1/5

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

    No annotations are provided, so the description must carry the burden. The description gives no information about side effects, required permissions, or what happens during the update (e.g., partial vs full replacement, idempotency).

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

    Conciseness2/5

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

    The description is only 4 words, which is too minimal. While concise, it omits essential information, sacrificing completeness for brevity. It does not follow the principle of every sentence earning its place.

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

    Completeness1/5

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

    The tool has 3 parameters (2 required, one with nested object) and no output schema. The description fails to explain what 'update' entails, what the body object should contain, or what the response looks like. Contextually incomplete.

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

    Parameters1/5

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

    Schema description coverage is only 33% (only 'options' has a description). The description does not explain 'dataLakeName' or the structure of 'body'. The agent has no hint about what fields to include in the body object.

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

    Purpose2/5

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

    The description 'Update a Data Lake' is a verb+noun but lacks specificity. It does not distinguish from siblings like datalake_create or datalake_get; the scope and effect of the update are unclear.

    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 (e.g., datalake_create for creation, datalake_delete for deletion). 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.

  • Behavior1/5

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

    No annotations are present, and the description does not disclose any behavioral traits such as whether the operation is destructive, idempotent, or requires specific permissions. The agent has no insight into 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.

    Conciseness2/5

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

    The description is extremely short, but lacks necessary detail. It is under-specified rather than appropriately concise, missing critical information for correct usage.

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

    Completeness1/5

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

    Given the complexity of the tool (required nested object parameter, no output schema, no annotations), the description is entirely inadequate. It does not explain the purpose of 'body', expected input structure, or return values.

    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 has two parameters: 'body' (object) and 'options' (object). Only 'options' has a description ('Optional parameters'), but the description adds no additional meaning. The 'body' parameter is completely undocumented, and the tool description does not clarify their roles.

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

    Purpose2/5

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

    The description 'Create a Data Lake' states the verb and resource, but lacks specificity. It does not distinguish from sibling tools like datalake_update or datalake_delete, and provides no context on what a Data Lake is in this API.

    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 usage guidelines are provided. The description gives no indication of when to use this tool versus alternatives, nor any prerequisites or exclusions.

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

  • Behavior1/5

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

    Without annotations, the description carries full responsibility for behavioral disclosure. It only states 'Acknowledge an alert' with no mention of side effects, idempotency, permissions, or what happens after acknowledgment. This is severely lacking.

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

    Conciseness2/5

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

    While very concise at three words, the description is underspecified and fails to provide necessary information. Conciseness is not valuable when it sacrifices completeness.

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

    Completeness1/5

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

    Given the lack of output schema, annotations, and detailed parameter info, the description is entirely too minimal. It does not explain the return value, effects, or any contextual details needed to use the tool correctly.

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

    Parameters1/5

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

    Schema description coverage is only 33% (options has a description). alertId and body are undocumented in both schema and description. The description adds no meaning to these parameters; it does not explain what body should contain or how alertId is used.

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

    Purpose3/5

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

    The description 'Acknowledge an alert' conveys a clear verb+resource combination, but it is minimal and does not differentiate from sibling tools like alert_get or alert_get_all. It lacks specificity about the type of alert or context.

    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, prerequisites, or when not to use it. The description does not clarify the conditions under which an alert should be acknowledged.

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

  • Behavior1/5

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

    No annotations provided, and the description fails to disclose behavioral traits such as side effects, required permissions, error handling, or idempotency. The agent has no insight into what happens during creation.

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

    Conciseness3/5

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

    The description is very short (one sentence), which is concise but at the cost of completeness. It is front-loaded with the core action, but every sentence should earn its place; this sentence is too sparse to be useful.

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

    Completeness1/5

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

    Given the complexity (required object parameter, no output schema, nested objects), the description is wholly inadequate. It does not explain the structure of the body, the possible options, or the return value, leaving the agent with insufficient information.

    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 description coverage is 50% (only 'options' has a description). The 'body' parameter, which is required, has no description, and the description does not add any meaning beyond the schema. The agent cannot determine what fields are needed in the body.

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

    Purpose3/5

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

    Description states 'Create an Atlas user', which is a specific verb and resource. However, it does not differentiate from the sibling tool 'user_create', which could cause confusion. The term 'Atlas user' is ambiguous without further context.

    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 'atlas_user_update' or 'user_create'. The description lacks any context about prerequisites or conditions for usage.

    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?

    With no annotations, the description must disclose behavioral traits. It only says 'Update', implying mutation, but no details on idempotency, side effects, permissions, or response behavior. This is insufficient for a mutation tool.

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

    Conciseness2/5

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

    The single-sentence description is under-specified for a tool with 3 parameters and nested objects. While it is brief, it does not provide enough information to justify its brevity—it lacks structure and detail.

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

    Completeness1/5

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

    Given the complexity (3 params, one nested object, no output schema, no annotations), the description is woefully incomplete. It does not explain the body structure, options semantics, or expected outcome.

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

    Parameters1/5

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

    Schema description coverage is only 33% (options described as 'Optional parameters'). The description adds no meaning to rolename or body. Given low coverage, the description should compensate but fails to do so.

    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 'Update a custom database role' clearly states the verb (update) and resource (custom database role), distinguishing it from sibling tools like create, delete, or get. However, it does not elaborate on scope or specifics.

    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., custom_db_role_create). The description lacks context on prerequisites or scenarios, leaving the agent to infer usage from the tool 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?

    Without annotations, the description must disclose behavioral traits. It only states the action but not side effects (e.g., whether existing team assignments are replaced or appended), authorization requirements, or rate limits. This is insufficient for safe usage.

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

    Conciseness2/5

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

    While the description is short (4 words), it sacrifices necessary detail. Conciseness should not come at the expense of clarity and completeness; this description is under-specified.

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

    Completeness1/5

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

    Given the complexity (3 params including a nested 'body' object, no output schema, no annotations), the description is severely incomplete. It fails to explain expected input format, response, or prerequisites, making it inadequate for effective tool use.

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

    Parameters1/5

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

    The input schema has 3 parameters with low description coverage (33% only for 'options'). The description adds no meaning to 'projectId' or 'body', leaving agents uncertain what the body should contain (e.g., team IDs, assignment rules). This is a critical gap.

    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 'Assign teams to a project' clearly indicates the action (assign) and resource (teams to a project), distinguishing it from sibling tools like project_get_teams (retrieval) and project_create (project creation). However, it could be more specific about whether it replaces or adds teams.

    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., project_get_teams for reading, project_remove_user for user removal). There is no mention of prerequisites or scenarios where this tool is appropriate.

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

  • Behavior1/5

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

    No annotations provided, yet the description gives no behavioral detail beyond the action. It does not disclose side effects on user roles, permissions, associated data, or required permissions. For a mutation operation, this is insufficient.

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

    Conciseness3/5

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

    Single sentence, no redundant text. However, it is too brief to be informative, sacrificing necessary detail for conciseness.

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

    Completeness1/5

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

    Given 3 parameters, no output schema, and no annotations, the description is severely incomplete. It does not explain return values, error scenarios, or the overall effect, leaving the agent with insufficient context.

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

    Parameters1/5

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

    Schema coverage is only 33% (only 'options' described). The description adds no meaning to 'projectId' and 'userId' parameters. With low coverage, the description should compensate but does not.

    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: 'Remove a user from a project'. It uses a specific verb and resource, making it distinct from sibling tools like user or project creation.

    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 (e.g., project_delete or user_delete). Lacks prerequisites, conditions, or contexts where removal is appropriate.

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

  • Behavior1/5

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

    No annotations provided and the description gives no behavioral details such as whether deletion is reversible, side effects, idempotency, or required permissions. It is severely lacking.

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

    Conciseness3/5

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

    The description is a single sentence, which is concise but lacks sufficient detail to be helpful. It is not verbose but also not sufficiently informative.

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

    Completeness1/5

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

    With no output schema, no annotations, and minimal parameter documentation, the description is completely inadequate for a deletion tool that requires proper context (e.g., return values, side effects, parameter relationships).

    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 description coverage is only 33% (only 'options' described). The tool description adds no extra meaning for parameters like clusterName or indexId, failing to compensate for the low 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 uses a specific verb 'Delete' and resource 'Atlas Search index', clearly distinguishing it from sibling tools like atlas_search_create, atlas_search_get, 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 on when to use this tool vs alternatives, no prerequisites or conditions mentioned. The description is purely functional 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?

    No annotations are provided, so the description carries full burden. It only states the action 'update', without disclosing side effects, permissions, or whether the operation is reversible. Minimal transparency.

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

    Conciseness3/5

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

    Single sentence is concise but lacks necessary detail. It is front-loaded with the action, but could benefit from additional context without being wordy.

    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 presence of a complex nested 'body' parameter and no output schema, the description is incomplete. It does not explain return values, error behavior, or how to construct the request.

    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 only 33% (only 'options' has a description). The description does not explain the required 'body' object or 'userId' format, failing to add value 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?

    Description clearly states the tool updates an Atlas user by ID. It distinguishes from sibling tools through the verb 'update' and resource 'Atlas user', but lacks specificity on what fields can be updated.

    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 atlas_user_create or user_update. No prerequisites or context provided, leaving the agent to infer usage.

    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?

    No annotations provided, so the description carries the full burden. It only says 'Create' without disclosing behavioral traits such as idempotency, return value, or authentication requirements.

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

    Conciseness3/5

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

    The description is a single sentence of six words, which is concise but may omit important context. It earns its place but does not enhance usability.

    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 nested objects in the schema, the description lacks explanation of what a cloud provider access role is, required fields, side effects, or output. No output schema provided.

    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 description coverage is 50%: 'body' has no description and 'options' only says 'Optional parameters'. The tool description adds no extra meaning to the 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 verb 'Create' and the resource 'cloud provider access role'. The tool name and siblings (delete, get_all, update) distinguish it as the creation action.

    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 cloud_provider_access_update or delete. The description does not mention prerequisites or 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?

    Without annotations, the description must disclose side effects. It only states 'Create,' implying mutation, but does not mention required permissions, idempotency, or any written data behavior.

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

    Conciseness3/5

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

    The description is a single short sentence, making it concise. However, this conciseness sacrifices necessary detail, resulting in under-specification rather than efficient communication.

    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 lack of output schema and nested parameters, the description should explain return values and parameter structure. It fails to do so, leaving the agent without critical information for correct invocation.

    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 description adds no meaning beyond the schema. The 'body' parameter is an object with no description, and the schema's description for 'options' is vague ('Optional parameters'). The description does not clarify required fields or structure.

    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 'Create a custom database role,' specifying the verb and resource. It distinguishes from sibling tools like custom_db_role_delete or custom_db_role_get by the action 'create.' However, it lacks additional context about what a custom database role is.

    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, prerequisites (e.g., existing database), or situations where it should not be used. The description is purely functional with no usage context.

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

  • Behavior1/5

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

    With no annotations, the description must disclose behavioral traits. It only says 'Delete' without indicating irreversibility, required permissions, or consequences, leaving agents with insufficient safety context.

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

    Conciseness3/5

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

    The description is very concise (4 words) but lacks structure or completeness. While brevity is appreciated, it sacrifices necessary detail for agent understanding.

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

    Completeness1/5

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

    For a tool with only one required parameter and no output schema, the description is critically incomplete. It fails to provide context about deletion behavior, error states, or what happens to related resources.

    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 50% (only 'options' gets a description). The description adds no meaning beyond the schema; it does not explain 'dataLakeName' format or constraints, nor does it clarify the purpose of 'options'.

    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 Data Lake' clearly states the action (delete) and resource (data lake), distinguishing it from sibling tools with distinct actions like create, get, or update.

    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 checking prerequisites or potential side effects. The description only states the action.

    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 does not disclose behavioral traits such as pagination behavior, result limits, ordering, or any side effects. With no annotations, this is a significant gap for a listing tool.

    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 front-loaded and efficient. However, it may be too minimal, lacking necessary 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 no output schema and a single parameter, the description fails to explain the return format, pagination details, or that it returns an array. The tool is under-specified 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?

    The schema provides 100% coverage with a description for the 'options' parameter, indicating pagination. The tool description adds no additional 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.

    Purpose3/5

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

    The description 'Get all projects' clearly indicates the tool lists projects, but it lacks specificity to distinguish it from siblings like project_get_by_id or project_get_by_name. It is adequate but does not differentiate the scope or context.

    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 alternative project retrieval tools. There is no mention of prerequisites, limitations, or scenarios where other tools would be more appropriate.

    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?

    No annotations exist, so the description must disclose behavior. It only says 'Update' which implies mutation, but no details on whether it overrides, merges, requires permissions, or has side effects. Very minimal transparency.

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

    Conciseness3/5

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

    The single-sentence description is concise but under-informative. It could be expanded slightly without losing 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?

    Given nested objects, no output schema, and no annotations, the description is insufficient. It omits the update behavior, return values, error handling, and permission requirements.

    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 50% (only options has a description). The description adds no extra meaning to parameters. For a parameter with nested objects, more guidance is needed.

    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 'project whitelist entries', and the '(legacy)' suffix distinguishes it from newer tools. However, the purpose is clear but lacks explicit differentiation from sibling update tools (none exist).

    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 or delete. No prerequisites, limitations, or use cases are provided.

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

  • Behavior1/5

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

    No annotations provided. Description lacks behavioral details such as read-only nature, pagination, or rate limits. For a tool retrieving all items, this is a significant gap.

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

    Conciseness3/5

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

    The description is concise but lacks structure. It is a single sentence without sections, which is acceptable but minimal 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?

    Given no output schema and sparse description, the definition leaves out key information like return values, error handling, and expected behavior. Incomplete for effective tool selection.

    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?

    Only one parameter 'options' with a generic description 'Optional parameters'. The description adds no meaning beyond the schema, leaving the agent unclear on what options are available.

    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 all', the resource 'cloud provider access roles', and scope 'for the project'. It distinguishes from sibling tools which focus on create, delete, update.

    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. It does not mention any prerequisites, exclusions, 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.

  • Behavior2/5

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

    No annotations are provided, so the description must carry the full burden. It only states 'Create a new cluster' without disclosing behavioral traits like side effects, permissions required, or what happens if the cluster already exists. This leaves significant gaps in understanding the tool's behavior.

    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, 'Create a new cluster,' which is concise and front-loaded. While it wastes no words, it could benefit from slight expansion to improve completeness without sacrificing brevity.

    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 of nested objects in the input schema and the absence of an output schema, the description is severely incomplete. It fails to explain the structure of the body parameter, what providerSettings expects, or the return value, leaving agents unsupported for correct invocation.

    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 input schema has 100% description coverage for top-level parameters but nested properties (name, clusterType, providerSettings) lack descriptions. The tool description adds no parameter information beyond the schema, failing to clarify the meaning or format of nested fields.

    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 'Create a new cluster' uses a specific verb and resource, clearly indicating a creation operation. It distinguishes from sibling tools like cluster_get, cluster_update, and cluster_delete by focusing on creation, leaving no ambiguity about the action.

    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. There is no mention of prerequisites, conditions, or context that would help an agent decide to invoke this tool over others.

    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?

    No annotations are provided, so the description carries full burden. It mentions the output is base64-encoded gzip, but does not disclose whether the operation is read-only, any size limits, or authentication requirements. The behavioral disclosure is minimal.

    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 front-loaded and clear. It avoids redundancy but could be slightly expanded without losing 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?

    Given no output schema and no annotations, the description is incomplete. It does not explain the options object, the format of the returned data beyond gzip base64, or any error conditions. The tool's overall behavior is under-specified.

    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 description coverage is 50% (options has a vague description, dataLakeName has none). The description adds meaning for dataLakeName (the name of the Data Lake) but does not explain the options object's possible fields or their purpose. The parameter semantics are weak.

    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 query logs in gzip/base64 format for a Data Lake. It distinguishes from sibling datalake_get (which likely retrieves the Data Lake metadata) and datalake_get_all. However, it could be more specific about the stream aspect.

    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 datalake_get. No prerequisites or context provided. The description does not help the agent decide between this and other datalake-related tools.

    Conciseness3/5

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

    The description is a single concise sentence, but it is overly brief and lacks important details. It is concise but at the expense of completeness, making it minimally adequate.

    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 three parameters including a nested object and no output schema, the description is insufficient. It does not explain what fields are updatable in 'body', what the 'options' object may contain, or what the tool returns after update.

    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, so the baseline is 3. The description adds no additional meaning beyond the schema. The 'body' parameter is an object with a generic description ('Updated user details'), which could be clarified.

    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 resource (existing database user). However, it does not differentiate from the sibling tool 'atlas_user_update', which updates Atlas users. The tool name 'user_update' and sibling presence suggest this is for non-Atlas users, but the description lacks this context.

    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 'user_create' or 'atlas_user_update'. No prerequisites, conditions, 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.

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It fails to disclose whether this is read-only, response size limits, pagination, or authentication requirements beyond basic intent.

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

    Conciseness3/5

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

    The description is a single sentence with no fluff, but it is under-specified. Conciseness is acceptable but at the cost of completeness.

    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 no output schema, no annotations, and a complex nested parameter, the description should elaborate on expected output or option details. It is insufficient for an agent to use effectively.

    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 sole parameter 'options' is described only as 'Optional parameters' in the schema. The description adds no additional meaning about what options are available or how they affect the query.

    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 'all alerts' for the project, clearly distinguishing it from siblings like alert_get (single alert) and alert_acknowledge.

    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 alert_get for individual alerts. No mention of prerequisites, filtering, or pagination.

    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?

    With no annotations, the description should disclose behavioral traits. It only states 'Get details' without indicating read-only nature, authentication needs, or potential 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. It could slightly benefit from more detail, but it 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?

    No output schema is provided, and the description doesn't hint at the return structure. For a tool with a nested 'options' parameter, the description is adequate but lacks 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%, so baseline is 3. The description adds no extra meaning; the 'options' parameter is not elaborated beyond the schema's minimal description.

    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 details for a specific Atlas Search index, distinguishing it from listing or creation tools. However, it does not specify what 'details' include, which could be slightly ambiguous.

    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 like atlas_search_get_all, nor any prerequisites or context for invocation.

    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?

    No annotations are provided, so the description must fully disclose behavioral traits. It only states 'Create or update' without detailing what happens on update, whether it replaces or merges, required permissions, rate limits, or side effects. The description is insufficient for an agent to understand the tool's behavior.

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

    Conciseness3/5

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

    The description is a single concise sentence with no waste. However, it is too brief to be fully informative and could benefit from additional structured detail without losing 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?

    Given the complexity of an upsert operation with a nested parameter (body) and no output schema, the description is incomplete. It fails to explain the expected format of body, the effect of options, or return values, leaving significant gaps for an agent.

    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 description coverage is 67% (clusterName lacks description, body is 'Analyzer definition(s)', options is 'Optional parameters'). The description adds no extra meaning beyond the schema. The nested body parameter lacks details about its structure, and options remains vague.

    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 or update), the resource (Atlas Search analyzers), and the scope (for a cluster). It effectively distinguishes from sibling tools like atlas_search_create (which creates a search index) and atlas_search_get_all_analyzers (which lists analyzers).

    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 (e.g., atlas_search_create, atlas_search_update), nor any prerequisites or conditions. Missing context on behavior when an analyzer already exists or when to prefer upsert over separate create/update.

    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?

    With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states the basic action without mentioning permissions, rate limits, error handling (e.g., user not found), or any side effects. This is insufficient for safe invocation.

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

    Conciseness3/5

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

    The description is a single short sentence, which is concise but overly minimal. It lacks structured detail that would aid understanding without being overly verbose, but it does not waste 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?

    Given the tool has no output schema and no annotations, the description should explain return values and error conditions. It does not, leaving significant gaps in understanding what the tool returns or when it might fail.

    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 description coverage is 50% (userId has no description; options only says 'Optional parameters'). The description adds no additional meaning beyond the schema, so it fails to compensate for the lack of parameter documentation.

    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 'Get Atlas user by ID' clearly states the action (get) and resource (Atlas user) with a specific identifier (ID), distinguishing it from sibling tools like atlas_user_get_all or atlas_user_get_by_name that retrieve users differently.

    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 atlas_user_get_by_name or atlas_user_get_all. Missing context about scenarios where ID is available vs. name, leaving the agent without decision support.

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

  • Behavior1/5

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

    No annotations are provided, so the description carries the full burden. However, it only states the action without disclosing side effects, permissions, or behavior beyond creation. For a write operation, this is insufficient.

    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 concise and front-loaded. While very brief, it effectively communicates the core function without unnecessary 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?

    No output schema and no description of return values. The body parameter is complex (nested object) but not explained in the description. Given the complexity, the description is 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 description coverage is 100% with adequate descriptions for each parameter. The tool description adds no extra meaning beyond what the schema provides, 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 'Create a snapshot restore job for a cluster' clearly states the verb (create) and resource (snapshot restore job). It distinguishes from sibling tools like cloud_backup_get_restore_job (read) and cloud_backup_get_snapshot (get snapshot).

    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 given on when to use this tool versus alternatives. With many sibling tools, the lack of context for when to choose create_restore_job over other backup operations reduces usability.

    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?

    No annotations are present, so the description must fully disclose behavior. It only states the action but does not mention that deletion is destructive, irreversible, or requires specific permissions. Critical details for a delete operation are absent.

    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 (3 words) and front-loaded. While efficient, it could include a bit more context without losing brevity, such as indicating the parameter 'clustername' identifies the target.

    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 action like cluster deletion, the description is overly minimal. It lacks information about irreversible consequences, cascading effects, or post-deletion state. An output schema is absent, so 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 both parameters described. The description adds no value beyond the schema, so baseline score of 3 applies. It does not explain the 'options' object or provide additional context.

    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 'Delete a cluster' clearly states the action and resource, distinguishing it from sibling tools like cluster_create or cluster_get. However, it could be improved by noting the permanence of the deletion.

    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 cluster_update or cluster_get. Missing context like prerequisites (e.g., cluster must exist, not in use) or when deletion is appropriate.

    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?

    With no annotations provided, the description carries full burden for behavioral disclosure. It only says 'test primary failover', implying it is non-destructive, but does not explicitly state whether it is reversible, requires permissions, or impacts production. This is insufficient for a potentially impactful operation.

    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 action. However, it is very brief and could be slightly more structured to include 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?

    The tool performs a complex operation (primary failover test) with no output schema, yet the description does not explain what the outcome is, how to interpret results, or how it integrates with other cluster tools. This leaves significant 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% with descriptions for both parameters (clustername and options). The description adds no extra meaning beyond what the schema provides, 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?

    The description clearly states the action (initiate) and the resource (test primary failover on the cluster). It distinguishes this tool from sibling cluster tools as none of them mention failover, but it could be more specific about what the test entails.

    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 like cluster_update or other cluster operations. There is no mention of prerequisites, context, 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.

  • Behavior2/5

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

    No annotations provided. The description does not disclose any behavioral traits such as pagination, sorting, authentication requirements, or response structure. It is too minimal for a read operation with no output 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?

    Single sentence, zero waste. Every word is necessary. Highly 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?

    Given no output schema and a single parameter, the description should at least clarify what the returned data contains (e.g., list of role objects). It also lacks details on filtering or pagination via 'options'. Incomplete for practical 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% (one optional object parameter). The description adds no value beyond the schema's 'Optional parameters' description. Baseline 3 applies as schema does the work, but schema description is also minimal.

    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 uses a clear verb ('Get') and specific resource ('all custom database roles'). It distinguishes from sibling 'custom_db_role_get' by implying a list, but could be more explicit about returning multiple items.

    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 siblings like 'custom_db_role_get'. No context about prerequisites, filters, or common use cases.

    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?

    With no annotations, the description carries full burden. It does not disclose read-only nature (implied by 'get' but not explicit), side effects, pagination, rate limits, or authentication needs. Minimal behavioral context beyond the function name.

    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, effective sentence that conveys the core purpose. It is appropriately front-loaded and concise, though it could benefit from additional structure without losing efficiency.

    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 lack of output schema and many sibling tools, the description does not provide enough context about return values, pagination, or filtering. It is insufficient for a complete understanding of the tool's usage.

    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 input schema defines only an 'options' object with a generic description 'Optional parameters'. The description adds no detail about what options are available or how to use them, leaving the agent without meaningful guidance despite 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 clearly states 'Get all Data Lakes for the project', specifying the verb (Get), resource (Data Lakes), and scope (all). It distinguishes from siblings like 'datalake_get' (likely single) and 'datalake_create' (mutation).

    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 'datalake_get' for a specific lake. The description only states what it does, not when it's appropriate or when to avoid 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?

    No annotations provided, so description must fully disclose behavior. It states a read operation but omits details like pagination, rate limits, permissions, or whether all events are returned at once. The behavioral disclosure is minimal.

    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 6-word sentence, very concise and front-loaded. However, it may be too terse, omitting useful context like return type or pagination, so not perfect.

    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 clarify what is returned (e.g., a list of event objects with fields). The tool has moderate complexity (2 params, one nested) but the description provides no information on return values, making it 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 coverage is 100% with both parameters described. The description adds no additional meaning beyond the schema; 'for a specific organization' matches the 'organizationId' parameter. Baseline 3 is appropriate as schema already documents the 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 'Get all events for a specific organization' clearly states the action and resource, distinguishing it from siblings like 'events_get' (single event) and 'events_get_all' (all events without org filter). However, it could be more precise about scope (e.g., 'all events in the organization' versus 'events for the organization').

    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 siblings. Sibling tools like 'events_get_all' (no org filter) and 'events_get_by_org' (similar name) are present, but the description does not contrast them or provide when-not-to-use advice.

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

  • Behavior1/5

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

    No annotations are provided, so the description is solely responsible for disclosing behavioral traits. The description merely states 'get organization details' without mentioning that this is a read-only operation, any required permissions, rate limits, or the nature of the response. This is a significant gap.

    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. It is front-loaded with the main action and resource. However, it could include slightly more detail (e.g., what 'details' means) without losing 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?

    Given no output schema and no annotations, the description is insufficient. It does not explain what 'details' are returned, any pagination or filtering, or error conditions. For a simple retrieval tool, more context is expected.

    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 ('organizationId' and 'options'). The description adds no additional meaning beyond what the schema already provides. Baseline score of 3 applies since schema does the heavy lifting.

    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') and the resource ('organization details') with a specific parameter ('by ID'). It distinguishes from sibling tools like organization_get_all, organization_delete, and organization_get_projects by specifying retrieval of a single organization by its identifier.

    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 organization_get_all for listing or organization_get_projects for related entities. There is no mention of prerequisites, limitations, or exclusion criteria.

    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?

    No annotations are provided, and the description does not disclose behavioral traits like idempotency, rate limits, permissions required, or pagination behavior. The agent gains no insight 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, direct sentence with no extraneous words. It is efficiently front-loaded, though it may be too terse to fully convey all necessary information.

    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 no annotations, the description is insufficient for an agent to fully understand the tool's behavior. It lacks information on response format, error handling, and how it differs from sibling 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 coverage is 100% (both parameters are described), but the description adds no extra meaning beyond the schema. It mentions 'users' but does not explain the options parameter or how organizationId is used. 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 action (Get) and resource (all users for an organization), which distinguishes it from sibling tools like organization_get_projects or organization_delete. However, it could be more specific about the scope (e.g., does it return all users globally or within the organization?). The purpose is clear but not highly detailed.

    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 user_get_all, organization_get_all, or other user-related tools. The description does not mention prerequisites, limitations, or context for appropriate 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?

    With no annotations, the description must disclose all behavioral traits. It only states the action ('Add') but does not explain whether adding is idempotent, replaces existing entries, or requires any conditions. No side effects or authorization hints are given.

    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, direct sentence with no extraneous words. It efficiently conveys the tool's action and target.

    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 nested parameter structure and the presence of many sibling tools for access list operations, the description is too sparse. It omits important context such as whether entries are cumulative, how the array is processed, and the effect of the optional options parameter.

    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 covers all parameters with descriptions for body and options, but nested properties (ipAddress, cidrBlock, comment) lack schema descriptions. The tool description does not add parameter-level clarity beyond what the schema provides. Baseline 3 is appropriate given the schema 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 uses the verb 'Add' and specifies 'IP addresses to the access list', clearly indicating the tool's function. It distinguishes from sibling tools like delete, get, and update, but could be more explicit about the project-level scope suggested by the tool name.

    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 like project_access_list_delete or project_access_list_update. The description lacks context for when to add versus modify or remove entries.

    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?

    No annotations provided, and the description does not disclose behavioral traits such as irreversibility, permission requirements, or side effects. The word 'Delete' implies mutation, but no further details.

    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 front-loaded and efficient, though it could be slightly expanded to include usage context without losing 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?

    For a simple delete tool, the description is adequate but lacks differentiation from the similar 'project_whitelist_delete' tool. No output schema, so no need to explain return values, but context about alternatives 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?

    Schema coverage is 100% with descriptions for both parameters, so the description adds no extra meaning beyond the schema. Baseline 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?

    Description clearly states 'Delete an IP access list entry from the project', which specifies verb and resource. However, it does not differentiate from the sibling tool 'project_whitelist_delete' which likely serves a similar purpose.

    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 over alternatives like 'project_whitelist_delete'. No context about prerequisites or typical use cases.

    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?

    With no annotations, the description bears full responsibility for behavioral disclosure. It only states 'delete', which implies destruction, but omits details about reversibility, permissions, side effects on related resources, or error handling.

    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 with one short sentence. It is front-loaded but could benefit from brevity without sacrificing informativeness. No wasted words, but slightly under-specified.

    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 lack of output schema, annotations, and detailed parameter info, the description is incomplete. It does not cover return values, error states, or side effects, leaving the agent with insufficient context for reliable invocation.

    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 description coverage is 50% (options has a description, projectId does not). The tool description adds no meaning beyond the schema. It fails to clarify the format of projectId or the contents of options, leaving ambiguity.

    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 project by ID' clearly states the action (delete), the resource (project), and the identifier (by ID). It effectively distinguishes from sibling tools like project_create, project_get, 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 usage guidance is provided. The description does not specify when to use this tool (e.g., prerequisites like project existence) or when not to use it. No alternatives 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?

    No annotations are provided, so the description must cover behavioral traits. It only states it retrieves teams but does not mention side effects, error handling (e.g., if projectId does not exist), rate limits, or read-only nature. This is insufficient for an agent to understand consequences.

    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 with no unnecessary words, achieving high conciseness. However, it is too minimal and could benefit from a slightly longer structure that includes key behavioral information 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 no output schema and moderate complexity (nested object parameter), the description does not explain what the returned teams represent, whether pagination is used, or any other context. Sibling tools like project_get_all provide more detail, making this description feel incomplete.

    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 has 50% coverage (options parameter has a description, but projectId does not). The description adds no additional meaning beyond the schema; it only restates that teams are retrieved by project ID. The 'options' parameter, which is a nested object, is left entirely unexplained, so the agent cannot know what optional parameters it accepts.

    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 'teams', and specifies the key parameter 'project ID'. This distinguishes it from sibling tools like project_get_all (gets all projects) and project_get_by_id (gets project details).

    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, and no exclusion criteria. It is a simple read operation, but without context, the agent cannot know if it's appropriate to call this in a given scenario.

    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?

    No annotations provided, and the description only states 'Add IP addresses to the whitelist (legacy)'. It does not disclose mutability, permission requirements, rate limits, or consequences of the operation.

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

    Conciseness3/5

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

    The description is a single sentence, which is concise and front-loaded. However, it is under-specified, missing critical details needed for correct usage.

    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, nested objects in the body parameter, and low schema coverage, the description is incomplete. It does not explain what the tool returns, how the body should be structured, or any side effects.

    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 description coverage is 50% (only the options parameter has a description). The description does not explain the format or constraints of the body parameter, which is an array of objects with ipAddress, cidrBlock, and comment.

    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 'Add' and the resource 'IP addresses to the whitelist', and marks it as legacy. This distinguishes it from sibling tools like delete, get, update.

    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 update or delete. No context on prerequisites 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.

  • Behavior2/5

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

    No annotations are provided, so the description must disclose behavioral traits. It implies a read-only operation but does not confirm idempotency, authorization requirements, error scenarios, or the implications of being legacy (e.g., deprecation warnings).

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

    Conciseness3/5

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

    The description is a single sentence, which is concise, but lacks necessary detail. It is front-loaded but does not fully earn its place due to missing guidance and parameter info.

    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, the description should explain return values (e.g., list of entries, fields). It does not mention pagination, rate limits, or legacy migration steps. For a list tool, this is incomplete.

    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 input schema has 100% coverage with one parameter 'options' described as 'Optional parameters' with a default of {}. The description adds no further meaning about what options can be passed (e.g., filtering, pagination, format), leaving the agent with insufficient detail.

    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 'IP whitelist entries', and the scope 'for the project', and distinguishes itself from siblings like 'project_whitelist_get' by indicating it returns all entries. The '(legacy)' label also differentiates it from modern alternatives.

    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 guidance on when to use this tool vs. alternatives. It marks the tool as legacy but fails to specify what newer tool should be used instead (e.g., 'project_access_list_get_all' from siblings). No exclusions 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.

  • Behavior2/5

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

    With no annotations provided, the description should disclose behavioral traits like idempotency, permissions, or error handling. It only states 'Get details' without mentioning if it is read-only, what happens on invalid IDs, or any rate limiting.

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

    Conciseness3/5

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

    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 explain what 'details' are returned. It also fails to elaborate on the 'options' parameter, leaving the agent guessing about its purpose or 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 description coverage is 100%, and both parameters have descriptions in the schema. The description adds no new meaning beyond the existing schema definitions.

    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 'Get details of a specific event' clearly specifies the action (Get) and resource (event), distinguishing it from sibling tools like events_get_all (which retrieves all events) and events_get_by_org (retrieves events by organization).

    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 events_get_all or events_get_by_org. It does not mention that it requires an eventId or that it is for a single, known event.

    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?

    Without annotations, the description must disclose behavior. It only states 'Create a new Atlas Search index' with no mention of side effects, idempotency, permissions, or whether the index must not already exist.

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

    Schema coverage is 100% with basic parameter descriptions. The description adds no additional meaning beyond the schema (e.g., specifying the 'body' structure or valid options). 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 'Rename an organization' uses a specific verb and resource, clearly indicating the action. Among sibling tools, no other tool performs a rename, so it is well-distinguished.

    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. The description lacks context about prerequisites, scenarios, 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.

  • Behavior2/5

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

    With no annotations, the description must disclose behavioral traits. It mentions 'POST semantics' but does not explain implications like idempotency, required permissions, or side effects. The agent is left guessing about updates vs. creations and error conditions.

    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 without unnecessary words. It is appropriately front-loaded with the verb and resource. Could be slightly more informative, but it is 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?

    Given the tool has a nested array parameter and no output schema, the description lacks details on return values, error handling, or behavior when an entry exists. It does not cover prerequisites or effects, leaving 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 description coverage is 100%, so the baseline is 3. The description adds '(POST semantics)' but no further meaning beyond the schema's 'upsert' hint. The items' fields (ipAddress, cidrBlock, comment) are self-explanatory from 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') and the resource ('IP access list entries for the project'), and adds context with '(POST semantics)' to indicate upsert behavior. This distinguishes it from sibling tools like project_access_list_create and project_access_list_delete.

    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 explain that this is for upserting entries, nor does it compare to project_access_list_create or project_access_list_delete.

    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?

    No annotations provided. Description only says 'Create a new project' without disclosing behavioral traits such as permissions required, side effects, or idempotency.

    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 with no waste. Slightly too minimal but still 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?

    No output schema and no annotations. The description fails to explain return values, error conditions, or any additional context needed for a creation 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 coverage is 100% but description adds no meaning beyond what the schema already provides. Baseline 3 is appropriate as schema does the heavy lifting.

    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 states 'Create a new project' with a specific verb and resource. Among siblings like project_delete, project_get_all, this clearly distinguishes as a creation tool.

    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., project_assign_teams). 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.

  • Behavior2/5

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

    No annotations are provided, so the description carries full burden. It does not disclose behavioral traits such as read-only nature, authentication requirements, or any side effects. A simple 'Get' implies read-only, but it is not stated, leaving ambiguity.

    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, concise and to the point. It could be slightly expanded without becoming verbose, but meets efficiency standards.

    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 many sibling tools, the description lacks completeness. It does not specify what project details are returned, how the options parameter affects output, or any edge cases. More context is needed 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% with basic descriptions for both parameters. The tool description adds no additional 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.

    Purpose4/5

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

    The description clearly states the action (Get) and the resource (project details by ID). It distinguishes from sibling tools like project_get_all and project_get_by_name by implying a single lookup by ID, but does not explicitly differentiate.

    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 like project_get_by_name or project_get_all. The usage is implied through the parameter, but an agent would benefit from contextual cues.

    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?

    No annotations provided. The description does not disclose important behavioral traits such as pagination limits, authentication requirements, or potential performance impact of fetching all users.

    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 concise with a single sentence. It lacks structure but is efficient; 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?

    Given no annotations, no output schema, and a nested parameter, the description is insufficient. It does not clarify pagination behavior or what 'all users' means in a potentially large dataset.

    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 'options' parameter described as 'Optional parameters for pagination and filtering'. However, the tool description adds no additional 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 'Get all database users' clearly states the action (get) and the target (all database users). It distinguishes from sibling tools like user_get (single user) and user_create.

    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 user_get. No mention of filtering or pagination context despite the options parameter.

    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?

    No annotations are provided, and the description does not disclose any behavioral traits beyond the action. It does not state whether the operation is read-only, requires authentication, or has side effects. For a listing tool, this is insufficient.

    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 states the purpose. No extraneous words or structure issues.

    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 simplicity of the tool (2 parameters, no output schema), the description is minimally adequate but lacks context such as return format, pagination, or permission requirements. It is complete enough for basic use but not rich.

    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 description adds no parameter information beyond the schema. The required clusterName is not explained, and the options object is only described as 'Optional parameters' in the schema. With 50% schema coverage, the description should compensate but does not.

    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 all Atlas Search analyzers for a cluster', using specific verb+resource+scope. It distinguishes from siblings like atlas_search_get_all (which likely gets all search indexes) and atlas_search_upsert_analyzer (which creates/updates a specific analyzer).

    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 usage guidance is provided. The description does not specify when to use this tool versus alternatives such as atlas_search_get (for a specific analyzer) or atlas_search_upsert_analyzer (for modifications).

    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?

    No annotations are provided, and the description does not disclose any behavioral traits such as pagination, filtering, sorting, or performance implications. The optional 'options' parameter is unexplained.

    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, concise and front-loaded with key information, with no unnecessary 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?

    Given the lack of output schema, no annotations, and an undocumented nested options parameter, the description is insufficient for an AI agent to correctly invoke the tool without additional knowledge.

    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, but the description only says 'Optional parameters', adding no meaning beyond the schema. The baseline is 3, but no additional value 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 'Get all Atlas users for the project' clearly states the verb (Get), resource (all Atlas users), and scope (for the project), distinguishing it from siblings like atlas_user_get_by_id and atlas_user_get_by_name.

    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 atlas_user_get_by_id or user_get_all. The description lacks any when-to-use 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?

    No annotations are provided, and the description only states 'Get', implying a read operation. It does not disclose any behavioral traits such as authentication requirements, error handling (e.g., if user not found), or rate limits. The description adds minimal transparency beyond the action itself.

    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 extremely concise at four words, with no extraneous information. It is front-loaded and directly 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?

    Given the tool has two parameters (one required), no output schema, and no annotations, the description is too minimal. It does not explain the return value, potential errors, or the behavior of the 'options' parameter. This leaves the agent with insufficient information to fully understand the tool's 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?

    The input schema shows two parameters: 'username' (required) and 'options' (object with description 'Optional parameters'). The description adds meaning by specifying 'by username' for the first parameter, but the 'options' parameter is not elaborated. Schema description coverage is 50%, and the description partially compensates with the verb 'get' implying retrieval.

    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 'Get Atlas user by username' clearly states the action (Get) and the target resource (Atlas user) with a specific identifier method (by username). It distinguishes from siblings like 'atlas_user_get_by_id' and 'atlas_user_get_all'.

    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 like 'atlas_user_get_by_id' or 'atlas_user_get_all'. The description does not mention any context for choosing this tool over others.

    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?

    No annotations are provided, and the description only implies a read operation ('get details') without confirming safety, required permissions, or any side effects. For a tool with zero annotation coverage, this is insufficient behavioral disclosure.

    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 with no unnecessary words. It is efficient, though it could be expanded slightly to improve completeness without losing 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?

    For a simple read tool with two parameters and no output schema, the description is minimally adequate. However, it lacks usage guidelines and behavioral context, which would improve completeness given the large set of sibling 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 coverage is 100%, so the schema already documents both parameters. The description adds no additional meaning beyond what the schema provides. The baseline of 3 is appropriate as the description does not hinder 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 'Get details of a specific cluster' clearly states the verb 'get' and the resource 'details of a specific cluster', which distinguishes it from sibling tools like cluster_get_all (list all) and cluster_create/delete/update (mutations).

    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. It does not mention that cluster_get_all should be used for listing clusters, or that this tool requires a clustername. The description is too brief to aid in tool selection.

    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?

    With no annotations, the description carries the full burden of behavioral disclosure. It fails to state whether the update is partial or full, what happens to unspecified fields, required permissions, or side effects. The term 'processArgs' is not explained.

    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 7 words with no wasted text. It efficiently communicates the core action and resource.

    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 (nested objects, no output schema), the description is incomplete. It does not explain how the update works (merge vs overwrite), what the response looks like, or any prerequisites. Users would need additional documentation.

    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 mentions 'processArgs' which corresponds to the 'body' parameter, but adds minimal meaning beyond the schema's 'Partial advanced configuration document'. No additional semantic enrichment.

    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 identifies the resource as 'advanced configuration (processArgs) for a cluster'. It clearly distinguishes itself from sibling tools like cluster_get_advanced_configuration (retrieval) and cluster_update (general update).

    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 cluster_get_advanced_configuration to view current config before updating or cluster_update for other settings. The description lacks explicit when-to-use and when-not-to-use 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?

    No annotations provided, and the description does not disclose behavioral traits such as reversibility, permission requirements, cascading effects, or error scenarios. For a destructive operation, this is a significant gap.

    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 very short and front-loaded. While concise, it could include more context without becoming verbose. It earns a 4 for being efficient but slightly under-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?

    Given no output schema, no annotations, and a destructive operation, the description is incomplete. It does not explain return values, error handling, or any special behavior, leaving the agent without essential context.

    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 description adds no meaning beyond the schema. The 'rolename' parameter lacks a description, and 'options' is minimally described as 'Optional parameters'. With only 50% schema coverage, the description should compensate but does not.

    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 custom database role' clearly states the verb (delete) and resource (custom database role), distinguishing it from sibling tools like create, get, update, and get_all.

    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 simplicity of a delete operation implies its usage, but there are no exclusion criteria 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?

    No annotations are provided, so the description must disclose behavioral traits. It only states the basic read operation, lacking details on idempotency, authorization needs, rate limits, or response structure.

    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 redundant information. It is appropriately front-loaded and efficient.

    Completeness2/5

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

    Given the complexity (no output schema, nested objects parameter), the description fails to explain the response format or any additional context required for correct use, making it 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 description coverage is 100% (the only parameter 'options' has a description 'Optional parameters'), but the description adds no extra meaning beyond the schema. The parameter remains vague, meeting the baseline 3 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 'Get all IP access list entries for the project', using a specific verb ('Get') and resource ('IP access list entries'), which distinguishes it from sibling tools like 'project_access_list_get' (singular) and CRUD 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?

    No guidance is provided on when to use this tool vs alternatives (e.g., project_access_list_get for a single entry). It does not mention context like pagination or filtering, nor 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.

  • Behavior2/5

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

    No annotations provided, so description bears full burden. Only states 'Get project details' without disclosing read-only nature, permissions, or any behavioral traits beyond the obvious.

    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 extraneous words. Could be more informative without losing 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?

    For a simple get-by-name tool with no output schema, the description is minimally adequate but lacks return format details or error conditions.

    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. Description adds no additional 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?

    Description clearly states verb 'Get', resource 'project details', and means 'by name'. Differentiates from siblings like project_get_by_id and project_get_all.

    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., project_get_by_id or project_get_all). 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?

    No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether the operation is read-only, idempotent, or has side effects. For a get operation, it is likely safe, but this is not communicated, leaving the agent uninformed.

    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 at one sentence, which is appropriate for a simple tool. It is front-loaded and every word serves a purpose. However, the brevity sacrifices some completeness, so it is not a perfect 5.

    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 (get by ID) and the lack of an output schema, the description is functional but incomplete. It does not explain what the returned alert contains or how errors are handled. The 'options' parameter is left unexplained, and no context is provided for edge cases.

    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 50%: 'alertId' lacks a description in the schema, and the description does not clarify its format or purpose. 'options' has a vague description ('Optional parameters') that the description does not improve upon. The tool's description adds no additional meaning to the parameters 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 'Get an alert by ID' clearly states the action (get), the resource (alert), and the identification method (by ID). It distinguishes from sibling tools like alert_get_all (which gets all alerts) and alert_acknowledge (which modifies state), making its purpose unambiguous.

    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 have a specific alert ID, but it provides no explicit guidance on when to choose this tool over alternatives like alert_get_all or alert_acknowledge. The context is clear, but no exclusions or recommendations are 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?

    With no annotations provided, the description must carry the full burden of behavioral disclosure. It only states 'Get', omitting any details about read-only nature, auth requirements, error behavior, 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?

    The description is a single concise sentence with no wasted words, but lacks structure or additional details that could aid readability.

    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?

    Without an output schema, the description should hint at the return value or job status fields, but it does not. The tool is simple, but the description is 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?

    All parameters are described in the input schema (100% coverage), so the description adds no extra meaning beyond what the schema already provides, leaving the baseline at 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 specifies the verb 'Get', the resource 'snapshot restore job', and the scope 'for a cluster', distinguishing it from sibling tools like cloud_backup_create_restore_job or cloud_backup_get_snapshot.

    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 specific restore job by ID, but provides no explicit guidance on when to use it versus alternatives, nor any prerequisites or exclusion criteria.

    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?

    No annotations are provided, and the description does not disclose behavioral traits such as read-only nature, idempotency, or potential side effects. The name 'get' suggests a read operation, but without explicit confirmation, the agent lacks important 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, concise sentence with no unnecessary words. However, it could be structured to include more information without adding 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 exists, and the description does not explain what 'details' entails. For a retrieval tool, information about the response structure is important. The description is insufficient on its own for an agent to fully understand the tool's output.

    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 parameters have descriptions), so the tool description does not need to add extra parameter meaning. The description adds no parameter context, but baseline 3 is appropriate given 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 'Get details of a specific snapshot' clearly states the action (get details) and the resource (specific snapshot). It effectively distinguishes from the sibling tool 'cloud_backup_get_snapshots' which lists snapshots.

    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 snapshot's details but provides no explicit guidance on when to use this versus other tools like 'cloud_backup_get_snapshots' or 'cloud_backup_create_restore_job'.

    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?

    No annotations provided; description implies read-only but does not explicitly state safety, error handling, or side effects. Minimal behavioral disclosure.

    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-loaded with key information; no wasted 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?

    Adequate for a simple get operation but lacks details about return structure or behavior for invalid cluster names.

    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 description adds no extra meaning beyond schema; 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?

    Clearly states the verb 'Get' and the resource 'advanced configuration (processArgs) for a cluster', distinguishing it from sibling tools like cluster_get and cluster_update_advanced_configuration.

    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 cluster_get; no mention of prerequisites or 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?

    No annotations provided, and description gives no behavioral details beyond the basic action. Does not disclose error handling, permissions, or response format. Minimal transparency.

    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 words, front-loaded with verb and resource. Efficient and clear.

    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 retrieval tool but lacks details on error behavior and return format, especially without an output schema. Somewhat 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?

    Description adds meaning by specifying retrieval 'by name', but does not explain 'options' parameter. Schema description coverage is 50%, and description partially compensates with context for rolename.

    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 action ('Get'), resource ('custom database role'), and retrieval method ('by name'), distinguishing it from sibling tools like create, delete, get_all, and update.

    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 usage guidance provided. Does not specify when to use this tool vs alternatives like custom_db_role_get_all or when to use create/update. Lacks context for proper selection.

    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 lacks behavioral details beyond a simple read operation. With no annotations, the description should disclose potential pagination, ordering, or limits, but it does not. The behavior is implied but not explicit.

    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, precise sentence that conveys the tool's purpose without any unnecessary words. It is well-structured and appropriately sized.

    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 list-all tool, the description is adequate but minimal. It does not mention that the tool returns a list of organization objects or any potential pagination. However, given the simplicity, it is marginally 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 input schema has 100% description coverage for the single 'options' parameter. The description adds no additional meaning beyond what the schema already 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 ('Get') and the resource ('all organizations'). It effectively distinguishes from sibling tools like organization_get_by_id (single org) and organization_get_projects (projects within an org).

    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 organization_get_by_id for a specific organization. There is no mention of context, prerequisites, or typical use cases.

    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?

    No annotations are present, so the description carries full responsibility for behavioral disclosure. It does not mention authorization requirements, pagination, rate limits, or whether the result set is scoped to the caller's permissions. This is insufficient for a tool that likely lists multiple resources.

    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 superfluous words. It is front-loaded with the verb and resource, 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?

    While the tool's purpose is clear, the description lacks important context such as output format, pagination behavior, or required permissions. Given the absence of an output schema and annotations, the description should provide more detail to be fully reliable 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%, so the schema already documents both parameters. The description adds no additional meaning beyond what the schema provides (e.g., the 'options' parameter remains vague). The baseline of 3 is appropriate as the schema is clear.

    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 ('projects'), and the scope ('for an organization'). It effectively distinguishes this tool from sibling project tools that operate on individual projects or lists without organizational context.

    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 like project_get_all or project_get_by_id. The description does not mention prerequisites, limitations, or exclusions, 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?

    With no annotations provided, the description carries the full burden of disclosing behavioral traits. However, it only states 'Get' without indicating whether the operation is read-only, requires specific permissions, has rate limits, or handles errors (e.g., entry not found). This lack of detail leaves the agent uncertain about side effects and constraints.

    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 front-loads the action and resource. Every word serves a purpose, with no redundant information. This is appropriately brief 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?

    Given the tool's simplicity (get a single entry) and complete parameter schema, the description is minimally adequate. However, it lacks details about the return format, error scenarios (e.g., missing entry), and does not hint at the output despite the lack of an output schema. Compared to sibling tools with richer descriptions, this one is 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?

    The input schema has 100% description coverage, with each parameter described adequately (e.g., accesslistentry is 'IP address or CIDR block entry'). The tool description adds no additional meaning beyond the schema, so the baseline score of 3 applies. No extra value is provided for the optional 'options' 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 'Get a specific access list entry for the project' clearly states the action (get), the resource (specific access list entry), and scope (project). It distinguishes this tool from siblings like project_access_list_get_all (list all) and project_access_list_create/update/delete (mutations), making it easy to select the correct tool.

    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, what prerequisites exist, or contrast it with siblings like project_access_list_get_all for retrieving multiple entries. The agent must infer usage solely from the name and brief description.

    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?

    No annotations are provided, so the description must suffice. It implies a read operation but doesn't explicitly state permissions, pagination, or non-destructive nature. The name hints at retrieval, but more behavioral details would improve transparency.

    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 filler. It is front-loaded and immediately communicates 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?

    Given the absence of an output schema, the description should hint at the return format (e.g., array of index definitions) or usage context. It does not, leaving agents unsure about what to expect. Sibling tools indicate CRUD operations, but no cross-references are provided.

    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 adds no additional meaning to the parameters; it only restates what the schema provides. The 'options' parameter remains undefined in the 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 'Get all', the resource 'Atlas Search indexes', and the scope 'for a cluster'. This distinguishes it from sibling tools like atlas_search_get (single index) and atlas_search_create.

    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 atlas_search_get or how to filter results. The description lacks context about 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?

    With no annotations, the description must disclose behavioral traits. It only states the purpose, omitting details on whether the operation is read-only, required permissions, pagination behavior, or potential performance implications.

    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 with no extraneous information, efficiently conveying 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?

    Given the lack of output schema and the tool's nature (listing all clusters), the description should include return format or pagination details. It does not address these, leaving the agent 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 coverage is 100%, so the input schema already documents the 'options' parameter. The description does not add additional meaning beyond what the schema 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?

    The description clearly states 'Get all clusters in the project', specifying the verb ('get') and resource ('all clusters'), and differentiates it from the sibling 'cluster_get' which retrieves a single cluster.

    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 use for retrieving all clusters, but provides no explicit guidance on when to use this tool versus alternatives like 'cluster_get' or 'cluster_get_advanced_configuration', nor mentions pagination behavior.

    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?

    With no annotations, the description must disclose behavioral traits. It only notes the tool is 'legacy', but does not mention authentication requirements, error handling, or what happens if the entry is not found. Minimal 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 very short (one sentence) and front-loaded with the key action. It is appropriately concise and wastes no 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?

    Given no output schema, the description should hint at return values (e.g., the entry details). It does not. However, sibling tool names and the parameter schema provide partial context. Adequate but 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 parameters 100%, with descriptions for whitelistentry ('IP or CIDR') and options ('Optional parameters'). The description adds no additional meaning beyond the schema, so baseline 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 'Get' and the resource 'specific IP whitelist entry for the project (legacy)'. It distinguishes from siblings like project_whitelist_get_all which retrieves all entries.

    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 entry by identifier, but provides no explicit guidance on when to use versus alternatives (e.g., when to use this vs project_whitelist_get_all). No exclusions or context are 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?

    No annotations are present, so the description must carry the full disclosure burden. It only states the action and legacy status, without revealing behavioral traits like irreversibility, required permissions, or side effects. This is insufficient for a mutation tool.

    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, focused sentence with no unnecessary words. It efficiently conveys the action and legacy note, making it optimally 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?

    The description is adequate for a simple delete operation but lacks specification of which project the entry belongs to (likely implicit, but not stated). The legacy status is noted but no alternative is suggested, leaving a minor gap in 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 does not add extra meaning beyond what the schema provides (e.g., 'IP or CIDR' for whitelistentry, 'Optional parameters' for options). Thus, it meets but does not exceed 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 clearly states the verb 'Delete' and the resource 'IP whitelist entry from the project', distinguishing it from sibling tools like create, get, and update. The '(legacy)' flag further clarifies its status.

    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 have both event ID and organization ID, but provides no explicit when-to-use, prerequisites, or 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?

    No annotations are provided, so the description must disclose behavioral traits. It states it's a read operation (get), but does not mention error handling, response format, or any side effects. Adequate but minimal.

    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 superfluous words. Clearly states purpose without unnecessary details.

    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-username tool with no output schema, the description covers the essential purpose. Could mention expected response or behavior on missing user, but not strictly necessary.

    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 adds 'by username', which aligns with the required parameter but does not provide additional meaning beyond the schema (e.g., what 'options' can contain).

    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 'Get a specific database user by username' clearly states the action (get), the resource (database user), and the method (by username). This distinguishes it from siblings like 'user_get_all' or 'atlas_user_get_by_name'.

    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., 'user_get_all' for listing, 'atlas_user_get_by_name' for Atlas users). The agent must infer from the tool name and siblings.

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