merge_merge_request

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

No annotations are provided, so the description carries full responsibility for disclosing behavioral traits. 'Merge a merge request' implies a mutating operation but does not disclose side effects, required permissions, failure conditions, conflicts, or what happens after a successful merge. This is a significant transparency gap for a destructive/persistent action.

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 extremely concise and contains no filler, but it is under-specified rather than efficiently detailed. The single sentence states the core action yet omits the behavioral and contextual information an agent would need, so it errs on the side of being too sparse.

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?

There is no output schema and no annotations, so the description is the only source of context. A merge operation involves mergeability checks, permissions, side effects, and result expectations, none of which are mentioned. The description is not complete enough for an agent to use this tool correctly in real-world scenarios.

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 description coverage is 100%, so parameters such as owner, repo, mergeRequestIid, and commitMessage are already documented. The description itself adds no parameter-specific meaning, but the schema carries the burden well enough to meet the baseline.

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 clear verb and resource: 'Merge a merge request'. It also differentiates itself from siblings because no other sibling tool performs the actual merge, so an agent can select it among create/get/list/update merge-request tools. However, it is very close to a paraphrase of the tool name and adds no scope or outcome context.

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?

There is no guidance about when to use this tool versus alternatives, nor any mention of prerequisites such as mergeability, approved reviews, or pipeline status. The description only states the action and gives the agent no decision guidance about when merging is appropriate.

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