Get group merge requests

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds real value beyond that by naming the return shape ('wrapper containing the original response and a list of MergeRequest models') and the error types raised. It stops short of mentioning pagination behavior or result limits, which matter for a list tool.

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 purpose sentence is front-loaded and useful, but the docstring scaffolding costs space: an 'Args' section whose only entry is the catch-all '**kwargs' conveys nothing about the 46 schema parameters. The Returns and Raises sections earn their place; the Args block does not.

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 lister with no output schema, the description covers purpose, error conditions, and the shape of the return value. What's missing is guidance on the large, confusing parameter surface (pagination, the 'argument' filter, the evidently copy-pasted group settings fields), which is the main way an agent could call this incorrectly. Otherwise it's complete for a filtered-list operation.

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 46 parameters, so the description carries the full burden and largely fails. It only gestures at group_id ('Additional parameters for the request (e.g., group_id)') and never explains the meaningfully named params an agent would actually need: 'argument' defaulting to 'state=opened', page/per_page/max_pages pagination, or why dozens of unrelated group-setting fields appear in the schema. It also claims group_id is required (MissingParameterError) while the schema marks it nullable with zero required params.

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?

States a specific verb and resource ('Get merge requests associated with a specific group'), which distinguishes it in substance from gitlab_get_project_merge_requests and gitlab_get_merge_requests. However, it never names those siblings, so the agent must infer the group-vs-project scope distinction.

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 on when to use this versus the many sibling alternatives (project-level, commit-level, or generic merge request listing). The only conditional info is a Raises clause about missing group_id, which is an error case, not usage guidance.

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