github_repos_set_user_access_restrictions

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

No annotations are present, so the description carries full burden. It only says 'Set user access restrictions' without explaining whether it replaces or merges existing restrictions, what permissions are required, or any 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?

The description is a single sentence but is under-specified. Conciseness should not sacrifice informativeness; here it provides no additional context beyond the name.

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 existence of sibling tools and the complexity of setting branch restrictions, the description is severely incomplete. It should explain that it replaces all user access restrictions on a branch and describe the expected body format.

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 coverage is 100%, but parameter descriptions are minimal (just parameter names). Description adds no meaning beyond the schema. Baseline 3 is appropriate as it doesn't improve understanding of the body structure or required fields.

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?

Description 'Set user access restrictions' is vague and essentially restates the tool name. It doesn't specify the resource (branch) or clarify that it sets restrictions on a protected branch, leaving ambiguity.

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 is provided on when to use this tool versus its siblings (add, remove, get user access restrictions). The agent has no way to distinguish the intended use case.

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