github_checks_set_suites_preferences

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

With no annotations, the description must fully disclose behavioral traits. It only says 'update' implying mutation, but lacks details on side effects, permissions, rate limits, or any safety implications.

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 extremely concise (6 words), but this brevity sacrifices necessary detail. It starts with the verb 'Update', but could be improved with more context in the same space.

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?

The description is severely incomplete: no output schema, no annotations, and the input schema's body parameter is opaque. It fails to explain what 'preferences' are, what the response looks like, or any constraints.

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 descriptions for owner and repo are just the parameter names, adding no value. The body parameter is an untyped object with no property descriptions. The description does not explain what properties the body should contain beyond the schema's minimal info.

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 it updates repository preferences for check suites, but it does not distinguish this from sibling tools like github_checks_create_suite or github_checks_rerequest_suite. The name and description are consistent, but the specific preferences are not explained.

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 tool versus alternatives. No context on prerequisites or scenarios. Simply states the action without any usage direction.

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