Trace Merge Request To Pipeline Failures

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

Annotations already indicate the tool is read-only, idempotent, and non-destructive. The description adds the behavioral detail of including trace tails for failed jobs, but does not elaborate on other behaviors like handling of pagination, limits, or empty results.

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, concise sentence that is front-loaded with the key verb and resource. However, it is slightly too terse to cover all necessary context for effective use.

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 tool has moderate complexity (tracing MR to pipelines to jobs), but the description omits details about the return structure and how parameters influence it. With no output schema, more completeness is required.

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?

With 0% schema description coverage, the description should explain the parameters. It only implies that project_id and merge_request_iid are needed, but does not describe pipeline_limit or trace_tail_lines, nor their significance in controlling 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 clearly states the action (trace) and the resource (merge request to pipelines and failed jobs), distinguishing it from sibling tools that focus on individual aspects like listing pipelines or explaining a single 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?

No explicit guidance on when to use this tool vs alternatives such as gitlab_get_merge_request_pipelines combined with gitlab_get_job_trace. The description does not mention prerequisites or scenarios where this composite tool is preferred.

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