List Deployment Merge Requests

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered without the description. The description adds only the deployment-scoped result semantics; it says nothing about what the response looks like, whether the list can be empty, or how pagination behaves.

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 short sentences with the scope stated first and supporting capabilities second. There is 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 read-only list tool with no output schema, the description covers intent but leaves the caller guessing about the return shape and pagination mechanics. Given 7 parameters at 0% schema coverage, it is borderline adequate rather than 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 description coverage is 0% across 7 parameters, so the description must carry the meaning. It only gestures at state, ordering and pagination; it never explains deployment_id (the sole required param), project_id, the direction vs. field distinction between sort and order_by, or the 'all' state value.

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 names a specific verb ('List') and a scoped resource ('merge requests shipped with a deployment'), which visibly separates it from the general gitlab_list_merge_requests or group/milestone variants. It stops short of explicitly naming the sibling it differs from, so it is clear but not fully differentiated.

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?

It gives one concrete use case ('for release notes and change tracking'), which implies when to reach for it, but offers no when-not guidance, no mention of the general list_merge_requests alternative, and no prerequisites such as required permissions or the deployment_id being mandatory.

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