Get Project Approval Rules

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds no additional behavioral context (e.g., pagination behavior, default page size). With rich annotations, a score of 3 is appropriate as it does not add but also does not contradict.

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, clear sentence with no wasted words. It is appropriately front-loaded and easy to parse. However, it could include more information (e.g., parameter hints) without sacrificing conciseness.

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?

Given the lack of output schema, 0% schema coverage, and the presence of sibling tools, the description is incomplete. It does not describe the returned data (list of rule objects), pagination behavior, or how approval rules differ from configuration. More detail is needed for an agent to use this tool effectively.

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%, meaning no parameter descriptions exist in the schema. The description does not explain the parameters (project_id, page, per_page), other than implying project_id identifies the project via the phrase 'project-level'. This is inadequate for agent usage.

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 'List project-level merge request approval rules' uses a specific verb and resource, clearly indicating the tool's purpose. However, it does not differentiate from sibling tools like gitlab_get_project_approval_configuration or gitlab_get_merge_request_approval_rules, which could cause confusion.

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 usage guidelines are provided. The description does not specify when to use this tool versus alternatives, nor does it mention any prerequisites or exclusions. Given the presence of sibling tools like gitlab_get_project_approval_configuration, this is a significant gap.

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