Trace Job To Commit And Merge Request

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is clear. The description adds only 'debugging context', which adds minimal behavioral insight beyond annotations. No contradiction.

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

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

A single, front-loaded sentence with zero waste. Every word contributes to understanding the tool's core function.

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 tracing task but omits details about the output (e.g., the difference between 'structured' and 'markdown' formats) and does not mention that multiple merge requests may be returned. Given no output schema, more completeness would be beneficial.

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%, yet the description does not explain any of the three parameters (job_id, project_id, output_format). While parameter names are somewhat self-explanatory, the agent gets no help on formatting or constraints beyond what the schema provides.

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

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

The description uses specific verb 'Trace' and clearly identifies resources: 'CI job to its commit, pipeline, and associated merge requests'. It distinctly differentiates from sibling tracing tools like gitlab_trace_issue_to_merge_requests or gitlab_trace_merge_request_to_pipeline_failures.

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 mentions 'for debugging context' which implies usage scenario, but it does not provide explicit guidance on when to use this tool versus alternatives (e.g., gitlab_get_job_trace, gitlab_get_merge_request), nor does it state prerequisites or limitations.

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