create_repository

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

No annotations are provided, so the description carries full burden. It indicates a write operation (creation), but does not disclose authentication requirements, rate limits, idempotency (whether duplicate names error), or side effects like initializing with a README. More context needed.

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 single sentence is concise and front-loaded, but it lacks any structure for the parameters. It is not verbose, but fails to include essential details. Every sentence should add value; here, the sentence is minimal but incomplete.

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 complexity (10 parameters, no output schema, no annotations), the description is far from complete. It does not explain return values, error scenarios, or parameter dependencies. The agent would be left with little context beyond the schema itself.

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 0% (no descriptions for any of the 10 parameters). The description adds no parameter details, leaving the agent to guess the meaning of fields like 'private', 'auto_init', 'gitignore_template', etc. This is a critical gap for a tool with many parameters.

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 verb 'create' and resource 'repository' for the authenticated user. It is not a tautology and distinguishes from siblings like 'create_issue' or 'create_pull_request', though it could be more specific (e.g., 'GitHub repository').

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. Given the many sibling tools (e.g., 'create_issue', 'create_pull_request'), the description should indicate when creating a repository is appropriate and what prerequisites exist.

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