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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds meaningful behavioral details: a bounded concurrency limit, result order preservation (MCP→GitHub→GitLab→HTTP), and that tags filter across all target kinds. This goes beyond the safety annotations and enriches the agent's understanding of execution behavior.

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

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

Two sentences, heavily packed with relevant details: scope, concurrency, ordering, and tag filtering. No redundancy or filler—every word earns its place.

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

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

The description covers the main aspects needed to invoke the tool: what it checks, ordering, concurrency, and tag filtering. It lacks an explicit statement about return format, but no output schema is present, and the description's mention of 'Results preserve... order' gives a hint. Given the simple parameter set and rich sibling context, it is nearly complete.

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

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

Schema coverage is 50% (only tags has a description). The tool description adds value by clarifying that tags filter all target kinds, going beyond the schema's 'Filter targets by registered server tags'. For timeout_ms, the schema provides default/min/max, so no additional semantics are needed. The description partially compensates for the coverage gap.

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

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

The description clearly states the action ('Check all registered MCP servers, GitHub Actions workflows, GitLab pipelines, and HTTP targets') with a specific verb and resource scope. It distinguishes from sibling tools by covering 'all' target kinds at once, as opposed to individual check tools.

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

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

The description implies use for bulk checking across all target types and notes a bounded concurrency limit as a key advantage. It does not explicitly name alternatives or state when not to use, but the 'all' scope and context from sibling names provide clear usage context without exclusions.

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

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

With annotations already declaring readOnlyHint=true and destructiveHint=false, the description adds useful context by specifying that it returns diagnostics for failed jobs and steps, which helps the agent anticipate the output. It does not contradict any annotations.

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

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

The description is a single sentence that is front-loaded with the action and resource, containing no redundant words. It is concise and well-structured.

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

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

For a read-only check tool with no output schema, the description adequately covers the purpose and return value (failed diagnostics). Combined with the safety annotations and the simple parameter set, this is sufficient context for an agent to use the tool correctly.

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

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

The schema provides a description for 'name' but not for 'timeout_ms' (50% coverage). The tool description does not explain either parameter or add meaning beyond the schema, failing to compensate for the undocumented timeout_ms parameter.

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

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

The description states a specific action ('Check the latest run'), a specific resource ('registered GitHub Actions workflow'), and the return value ('failed job and step diagnostics'). This clearly distinguishes it from sibling tools like check_gitlab_pipeline or check_http_target.

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

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

The description implies usage for GitHub Actions workflows but does not explicitly state when to use this tool vs alternatives like check_all or check_gitlab_pipeline. No exclusions or alternative tool mentions are provided, so usage context is only implicit.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, establishing a safe read-only operation. The description adds valuable context by specifying the return payload, including 'bounded trace diagnostics', which hints at a limit on trace length. It does not contradict any annotations.

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

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

The description is a single, well-structured sentence that front-loads the action and resource, then lists the specific output fields. It is concise with no wasted words, conveying all key information efficiently.

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

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

The description lists the return fields, which is helpful, but it omits explanation of the timeout_ms parameter and leaves 'bounded' vague. With no output schema and an additional undocumented parameter, the description is adequate but not fully complete for an agent to invoke correctly without guessing.

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

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

The schema describes 'name' but not 'timeout_ms', leaving 50% of parameter coverage. The tool description does not mention 'timeout_ms' at all, failing to explain its purpose or relationship to the 'bounded' diagnostics. Since schema coverage is only 50%, 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.

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

The description clearly states the tool's action ('Check') on a specific resource ('latest registered GitLab pipeline') and enumerates the specific returned diagnostics (failed job, stage, ref, commit, URL, bounded trace diagnostics). This distinguishes it from sibling tools like list_gitlab_pipelines and unregister_gitlab_pipeline.

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

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

The context for using this tool is clear: to retrieve failure details of the latest registered GitLab pipeline. It does not explicitly name alternatives or exclusions, but the sibling tools' names indicate different purposes (listing, unregistering), so an agent can infer when to use this one.

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

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

The description adds meaningful behavioral context beyond the annotations, such as DNS-pinned SSRF protection, bounded redirects/body reads, response assertions, and TLS-expiry diagnostics. These details inform the agent about safety measures and diagnostic capabilities, which is valuable. The annotations already declare read-only and non-destructive, so the bar is lower, but the description still provides additional useful context.

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

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

The description is a single, focused sentence that conveys the core action and key features. It is front-loaded with the main purpose, though the technical jargon (e.g., 'DNS-pinned SSRF') might be dense. Every phrase adds value, so it earns a high score.

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

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

Given no output schema, the description sufficiently explains what the tool does and what behaviors to expect (assertions, TLS diagnostics). It lacks explicit return format details, but for a read-only check tool with strong annotations, this is not a critical gap. The two-parameter schema is simple, and the description covers the core semantics.

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

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

Schema description coverage is 50% (only 'name' is described). The description does not mention or explain the 'timeout_ms' parameter, leaving its semantics undocumented in both schema and description. The description's mention of 'bounded redirects/body reads' only indirectly relates to timeout behavior, but it does not clarify how the parameter affects the check.

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

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

The description clearly states 'Check a registered HTTP target' with a specific verb and resource, and enumerates distinct capabilities like SSRF protection and response assertions. This distinguishes it from sibling tools like check_server or check_github_actions, which target different resource types.

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

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

The description implies the tool is for checking registered HTTP targets, but it does not explicitly state when to use it over alternatives or when not to use it. It lacks explicit exclusions or alternative tool references, relying on the name and context to convey usage.

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

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, covering the safety profile. The description adds that it lists tools and measures response time, which are behavioral details beyond annotations. However, it does not disclose error conditions or what 'health' entails.

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

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

The description is a single sentence that is direct and front-loaded. Every word contributes value: 'Check the health', 'registered MCP server', 'list tools', 'measure response time'. No filler or repetition.

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

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

For a simple read-only tool with good annotations and no output schema, the description covers the main actions. It could include details about return format or behavior when the server is not registered, but these are not critical given the tool's simplicity and safe annotation profile.

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

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

The schema describes 'name' but not 'timeout_ms'. The description does not explain the timeout parameter or its relation to response time measurement. With schema coverage at 50%, the description should compensate for the missing parameter semantics, but it doesn't.

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

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

The description uses a specific verb 'check' with resource 'registered MCP server', and explicitly lists what it does: list tools and measure response time. This clearly distinguishes it from sibling check_* tools for HTTP, GitHub Actions, and GitLab Pipelines.

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

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

The description states it checks a 'registered MCP server', giving clear context that this tool is for MCP servers specifically. It implies usage for MCP health checks but does not explicitly exclude alternatives like check_http_target or provide when-not-to-use conditions.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, and the description adds valuable context about the aggregated scope (servers, workflows, pipelines, HTTP targets) and the performance/uptime stats. It does not describe return format or potential heaviness, but for a read-only dashboard with annotations, the added context is meaningful. No contradiction with annotations.

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

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

The description is a single, compact sentence of 19 words that front-loads the verb and key content. Every word adds value, listing the covered resources and the type of statistics, with no filler or redundancy.

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

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

For a tool with two optional parameters and no output schema, the description gives a solid high-level picture of what the dashboard includes. The main gap is the complete absence of parameter semantics (e.g., how to adjust the time window), which prevents full operational understanding, but the core purpose is well covered.

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

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

Schema description coverage is 0% and the description does not mention the parameters 'hours' or 'include_tool_stats' at all. The schema only provides types/defaults, leaving their semantics entirely unstated. The agent cannot infer whether 'hours' is a time range or how 'include_tool_stats' alters the output.

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

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

The description uses a specific verb ('Get') and clearly states the resource ('dashboard overview') plus the exact coverage ('registered MCP servers, GitHub Actions workflows, GitLab pipelines, and HTTP targets') and the kind of data included ('uptime and performance stats'). This distinguishes it from the sibling tools that target individual resources or actions.

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

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

The description provides clear context by positioning this as a broad overview tool, which implicitly contrasts with the more specific sibling tools (e.g., check_server, list_http_targets). However, it does not explicitly state when to use this versus alternatives or mention exclusions, so it falls short of a 5.

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

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

Annotations already declare readOnlyHint true and destructiveHint false, so the safety profile is covered. The description adds minor context about the contents (database activity) but does not disclose any additional behaviors such as pagination or return shape.

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

The description adds context about output format (Markdown) and intended use beyond the readOnly and destructive annotations. However, it does not disclose the effect of the 'hours' parameter on the report's time window, nor any underlying behavior like network calls or caching.

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

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

The description is a single, front-loaded sentence that conveys the core action, scope, output format, and intended use without any redundant words. Every phrase earns its place.

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

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

For a simple tool with one optional parameter and no output schema, the description covers the output format and target resources, but omits the time-range parameter completely. This is a notable gap, though the overall tool is fairly simple.

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

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

The sole parameter 'hours' is not mentioned in the description, and schema description coverage is 0%. The description adds no meaning beyond the schema's type/default/min/max, leaving the agent to infer how the parameter affects the report.

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

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

The description clearly states the tool retrieves a human-readable Markdown health report covering MCP servers, GitHub Actions workflows, GitLab pipelines, and HTTP targets. The verb 'Get' and specific resource scope distinguish it from sibling check/report tools, and 'Markdown' adds further differentiation.

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

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

The description implies usage for obtaining an aggregate, human-readable report across multiple monitored resource types, and notes it can be pasted into chat or docs. It doesn't explicitly name alternatives or exclusions, but the context is clear enough for selection among granular check tools.

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is clear.

The description uses the specific verb 'Register' with the resource 'GitHub Actions workflow' and lists the key identifying parameters (owner, repository, workflow file or ID). This clearly distinguishes it from siblings like register_gitlab_pipeline or check_github_actions.

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

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

The description makes clear this tool is for registering GitHub Actions workflows, which implies usage context. However, it does not explicitly state when to prefer this over alternatives or provide exclusions, though sibling names fill some of that gap.

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

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

Annotations already declare this as a write (readOnlyHint=false) and non-destructive (destructiveHint=false) operation. The description adds valuable context: token values are not persisted (only the environment-variable name is stored) and self-hosted origins require HEALTH_MONITOR_GITLAB_BASE_URL_ALLOWLIST. This goes beyond the annotations to explain security-relevant behavior.

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

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

The description is two short sentences: the first states the primary action, the second conveys constraints. It is front-loaded and contains no redundant words.

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

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

Given the 7 parameters, high schema coverage, and absence of an output schema, the description is sufficiently complete. It covers the core purpose and key constraints, though it could briefly mention what registration implies (e.g., enabling monitoring), but the sibling check_gitlab_pipeline tool provides that context.

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

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

Schema description coverage is 86%, so the schema already documents most parameters clearly. The description's mention that 'only the token environment-variable name is stored' reinforces token_env semantics but is also present in the schema. No additional parameter-level meaning is added, so the baseline score of 3 applies.

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

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

The description clearly states the tool's function with a specific verb ('Register') and resource ('GitLab CI/CD project pipeline'), distinguishing it from sibling registration tools (e.g., register_github_actions, register_http_target). It also notes the default GitLab.com behavior, adding scope.

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

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

The description gives clear context for when to use this tool: to register a GitLab pipeline for monitoring. It also provides important usage constraints (GitLab.com allowed by default; self-hosted origins require allowlist). It does not explicitly name alternatives, but the specificity makes the intended use obvious.

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

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

Annotations indicate a write operation (readOnlyHint=false) and no destructive behavior. The description adds meaningful context beyond annotations: GET-only restriction, supported assertion types, and allowlist requirements for private origins. There is no contradiction with annotations.

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

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

The description is a single, well-structured sentence that front-loads the verb and resource type. Every phrase provides useful information without redundancy.

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

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

The description covers the core behavior, supported assertion types, and network constraints. It lacks explicit return-value or setup details, but no output schema exists and the tool is reasonably scoped. Sufficient for a registration tool.

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

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

The input schema has zero parameters, so baseline is 4. The description mentions endpoint and assertion types, but there are no parameters to document. This is acceptable given the empty schema.

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

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

The description clearly states the action ('Register'), the resource ('GET-only HTTP or HTTPS endpoint'), and the specific features (status, header, body, JSON, TLS-expiry assertions). This distinguishes it from sibling register tools for GitHub Actions, GitLab pipelines, and servers.

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

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

The description implies use for HTTP/HTTPS monitoring targets and provides context on network restrictions and prerequisites for private origins. It does not explicitly name alternatives, but sibling tools make the differentiation clear enough.

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

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

Annotations already declare non-read and non-destructive mutation. The description adds context about transport constraints and runtime policy restrictions, but it does not disclose side effects (e.g., persistence, overwriting, validation) or return behavior. The policy note provides some value beyond annotations.

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

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

Two sentences, front-loaded with the main action ('Register an MCP server'), followed by a compact list of transport rules. No redundant information with schema or annotations.

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

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

Despite annotations, the description lacks critical operational detail: how the server is identified, what input the tool accepts (schema is empty), what happens on success/failure, and whether registration persists. The transport guidance is useful but does not cover the overall registration workflow, leaving the tool ambiguous for an agent.

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

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

The schema has zero parameters with 100% schema coverage, so the baseline is 4. The description enriches the empty schema by explaining the three transport modes (http, sse, stdio) and their appropriate use, which is not evident from the schema itself.

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

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

The description uses the specific verb 'Register' with the resource 'MCP server', clearly distinguishing it from sibling tools like register_http_target, register_github_actions, etc. It also adds protocol specificity (http, sse, stdio), making the scope concrete.

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

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

The description explicitly instructs when to use http, sse, or stdio based on server type, including exclusions (sse only for legacy, stdio only if policy-allowed). However, it does not explicitly name alternative tools like register_http_target, so differentiation relies on the tool name.

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

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

Annotations already indicate a write operation (readOnlyHint=false), so the description's 'Configure' is consistent. However, it does not disclose behavioral traits like whether setting thresholds overwrites existing ones, applies per-server, or has side effects. Some extra context is added by naming the metrics, but there is room for more.

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

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

One concise sentence that is front-loaded with the verb and object, and it names the key metrics. No filler or redundant information.

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

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 simple annotations, the description covers the core purpose but omits important context about side effects (e.g., existing thresholds being replaced) and the requirement for a valid server name. It is adequate for a basic config tool but not fully complete.

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

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

Schema coverage is 75% (3 of 4 params have descriptions). The description names the threshold types, which aligns with the schema and helps clarify consecutive_failures_before_alert (which lacks a schema description). It does not add much beyond what the schema already specifies for the other parameters.

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

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

The description uses a specific verb ('Configure') and resource ('alert thresholds') and lists the key metrics involved. It clearly distinguishes this tool from sibling tools like check_server, get_uptime, and register_* which serve different purposes.

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

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

The description implies usage (when you need to set alert thresholds) but provides no explicit when-to-use vs alternatives or exclusions. It doesn't mention when not to use this tool, such as when only viewing thresholds is needed.

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

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

Annotations already flag the tool as destructive, and the description adds that it also removes stored check history, providing useful scope beyond the annotations. It does not mention reversibility or prerequisites, but the destructiveHint annotation covers the primary safety signal.

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

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

The description is a single sentence that is front-loaded with the action verb and contains no superfluous words. Every word contributes to understanding the tool's behavior.

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

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

For a simple one-parameter destructive tool, the description covers the core purpose and extra behavior (check history removal), but it omits parameter semantics and any note about expected outcomes or error behavior. With no output schema, some return-value context would improve completeness.

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

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

The input schema has one required parameter 'name' with 0% description coverage, and the description does not explain what 'name' refers to or provide any parameter guidance. The agent must infer from context, which is a significant gap for a tool with a single required parameter.

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

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

The description clearly states a specific verb ('Remove') and resource ('GitHub Actions workflow target'), and also notes the removal of stored check history. This distinguishes it from sibling unregister tools like unregister_gitlab_pipeline and unregister_http_target, making the purpose unambiguous.

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

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

The description implies usage (when you want to remove a GitHub Actions workflow) but does not explicitly provide when-to-use vs alternatives or exclusions. The sibling list shows similar tools for other target types, but no alternative is referenced in the description.

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

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

Annotations already indicate destructiveHint=true, but the description adds a concrete behavioral trait: 'and its stored check history' is removed. This provides useful side-effect context beyond the annotations.

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

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

The description is a single compact sentence that directly states the action and its key side effect. Every word earns its place with no redundancy.

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

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

For a simple single-parameter destructive tool, the description adequately covers the purpose and the important side effect. It does not need to explain return values, but it would benefit from explicitly connecting the 'name' parameter to the target being removed.

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

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

Schema description coverage is 0% for the only parameter 'name', and the description does not explicitly explain that 'name' refers to the registered GitLab pipeline target name. The meaning is only indirectly inferred from the tool name and description.

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

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

The description uses a specific verb 'Remove' with a clear resource 'GitLab pipeline target' and additionally states that stored check history is removed. This clearly distinguishes the tool from siblings like unregister_github_actions and unregister_http_target.

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

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

Usage is implied by the purpose: use when you need to remove a GitLab pipeline target. However, there is no explicit guidance about when not to use this tool or how it compares to alternatives such as unregister_http_target or checking a pipeline.

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

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

Annotations declare destructiveHint=true and readOnlyHint=false, and the description enhances transparency by disclosing that the operation also removes stored check history, a behavioral detail not present in the annotations. This adds useful context without contradiction.

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

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

The description is a single sentence 'Remove an HTTP target and its stored check history.' It is perfectly concise, front-loaded with the action verb, and contains no filler or redundant information.

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

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

For a simple one-parameter destructive operation with a clear annotation (destructiveHint=true) and no output schema, the description plus annotation covers the essential context. It could mention error behavior (e.g., if target not found) but this is not critical for a straightforward unregister action.

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

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

The input schema has one parameter 'name' with no description (0% schema description coverage). The tool description does not mention the parameter or explain that 'name' identifies the HTTP target to remove, leaving the agent to infer this from context. Given the 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.

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

The description clearly states 'Remove an HTTP target' with the specific verb 'Remove' and resource 'HTTP target', and adds 'stored check history' to distinguish from other unregister tools. This precisely differentiates it from siblings like unregister_server or unregister_gitlab_pipeline.

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

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

The context is clear: this tool is for unregistering HTTP targets. However, it does not explicitly mention when not to use it or suggest alternatives, relying on the resource name to guide the agent. No exclusions are stated, so this fits a 4.

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

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

While annotations already flag this as destructive, the description adds no extra behavioral context—it does not mention irreversibility, impact on historical data, or any side effects. It merely echoes the tool's name and purpose.

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

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

The description is a single, focused sentence that communicates the core action without fluff. It is optimally concise for the simple operation, though it sacrifices necessary detail in other dimensions.

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

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

For a destructive tool with one parameter, the description is underwhelming: it omits parameter semantics, consequences of removal, and any usage context. Even with annotations covering safety, the description fails to provide a complete picture of the operation.

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

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

The schema has one required 'name' parameter with zero description coverage, and the tool description does not clarify what 'name' refers to (e.g., hostname, display name, or ID). The description only implies that a server is being removed, leaving the parameter's exact format ambiguous.

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

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

The description clearly states the action ('Remove') and the resource ('a server from monitoring'), distinguishing it from sibling unregister tools that target different resource types (e.g., GitLab pipelines, HTTP targets). It is specific and unambiguous.

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

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

No guidance is provided about when to use this tool over alternatives, nor any prerequisite or context such as 'use when you need to stop monitoring a registered server'. The description simply restates the tool's function without offering decision-making support.

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