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 states it creates a repository but lacks behavioral details: no mention of authentication requirements, rate limits, what happens on failure (e.g., if name exists), or the response format. 'Create' implies mutation, but without annotations, more context is needed for safe use.

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, efficient sentence with zero waste. It's front-loaded with the core action and resource, making it easy to parse. Every word contributes to understanding the tool's purpose without redundancy.

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 annotations and no output schema, the description is incomplete for a mutation tool. It lacks details on authentication, error handling, rate limits, and what the tool returns. For creating a repository with 4 parameters, more context is needed to ensure reliable use by an agent.

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 100%, so the schema fully documents all parameters. The description adds no parameter-specific information beyond implying the tool creates repositories. Baseline is 3 since the schema does the heavy lifting, but the description doesn't enhance understanding of parameters like 'autoInit' or 'private'.

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 action ('Create') and resource ('GitHub repository'), specifying it's for 'your account'. It distinguishes from siblings like 'fork_repository' (which creates a copy) and 'search_repositories' (which finds existing ones), but doesn't explicitly contrast with all siblings. The purpose is specific but could be more precise about scope.

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 is provided. It doesn't mention prerequisites (e.g., authentication, permissions), when not to use it (e.g., for existing repositories), or direct alternatives like 'fork_repository'. The agent must infer usage from context alone.

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