Manage merge requests

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

Annotations indicate readOnlyHint=false and destructiveHint=false, but the description adds little behavioral context beyond listing actions. It does not disclose permission requirements, side effects of actions like merge or close, or any rate limits. The description lacks detail that would help an agent understand behavior 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 very short (one sentence) and front-loads the actions, but it is merely a list without any structuring or explanation. It could be improved by grouping actions or mentioning typical workflows, but it is not overly verbose.

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 18 parameters, no output schema, and a wide range of actions, the description is incomplete. It does not explain return values, error conditions, or action-specific parameter requirements. The agent would need to consult the schema heavily.

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 89%, so most parameters already have descriptions in the schema. The description does not add any parameter-level semantics; it only lists the available actions. Baseline of 3 is appropriate since schema handles the burden.

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 manages merge requests with a list of specific actions (list, create, update, approve, merge, close, etc.), which distinguishes it from sibling tools that are more narrowly focused (e.g., gitlab_get_merge_request). However, it could be more precise about the exact resource (GitLab merge requests).

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 on when to use this tool versus alternatives. There are siblings like gitlab_get_merge_request for reading a single MR, but the description does not mention trade-offs or exclusions. The agent must infer usage from the action list.

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