delete_group_permission

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('Remove') but doesn't disclose critical traits: whether this is destructive (likely yes, but not confirmed), authentication requirements, error conditions (e.g., if permission doesn't exist), or side effects. The mention of 'Returns: Confirmation of removal' hints at output but lacks detail on format or success/failure indicators.

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 appropriately sized and front-loaded: the first sentence states the core purpose, followed by structured 'Args' and 'Returns' sections. Every sentence earns its place, though the 'Returns' line could be more informative (e.g., specifying response format). No redundant or verbose content is present.

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 tool's complexity (a destructive operation with 2 parameters), no annotations, and no output schema, the description is minimally adequate but has clear gaps. It covers the basic action and parameters but lacks behavioral context (e.g., permissions needed, idempotency) and detailed output information. For a deletion tool, this leaves the agent under-informed about risks and results.

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%, so the description must compensate. It adds semantic meaning by explaining that 'repo_slug' refers to a 'Repository slug' and 'group_slug' to a 'Group slug', clarifying these are identifiers rather than display names. However, it doesn't specify format constraints (e.g., alphanumeric) or provide examples, leaving some ambiguity.

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 specific action ('Remove') and target ('a group's explicit permission from a repository'), distinguishing it from sibling tools like 'delete_user_permission' (which removes user permissions) and 'update_group_permission' (which modifies rather than removes). It precisely defines the verb+resource combination without being tautological.

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?

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing admin access), when not to use it (e.g., for inherited permissions), or direct alternatives like 'update_group_permission' for modifying permissions instead of removing them. Usage is implied only by the action described.

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