set_team_repo_permission

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

With no annotations, the description discloses the write nature and a blocking condition. However, it does not explain how existing permissions are handled, confirmation or side effects.

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?

Two short sentences and a list of permission values. Every sentence is relevant and no wasted words.

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 no output schema and incomplete parameter explanations, the description lacks behavior details like return value, error handling, or effect on existing permissions. Missing info for a mutation tool.

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%. Description only elaborates on the 'permission' parameter with allowed values. Other 4 parameters (org, team_slug, owner, repo) remain unexplained, failing to compensate for low coverage.

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?

Clearly states verb 'grant or update' and resource 'team's permission on a repo'. Additionally labels it as 'WRITE OPERATION', distinguishing it from read-only tools like get_repo_permission.

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?

Mentions a prerequisite regarding the READ_ONLY flag but does not specify when to use this tool vs alternatives like set_repo_collaborator_permission or when not to use it.

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