create_repository

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the action and scope, without mentioning side effects, permission requirements, error behavior, idempotency, or what happens on conflicts. It implies authentication via 'authenticated user' but does not disclose any consequences of the mutation. This is minimal disclosure for a create operation.

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 concise and front-loaded, stating the purpose in the first sentence and then listing parameters in a clear, structured format. It wastes no words and is easy to parse, making it efficient for an agent.

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 tool's simplicity (3 parameters, no enums, no nested objects) and the presence of an output schema, the description covers the basic intent but omits details like conflict behavior, rate limits, or authentication prerequisites beyond the phrase 'authenticated user'. It is adequate but not comprehensive 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?

The schema has 0% description coverage, so the description must compensate. It lists all three parameters with brief descriptions and, crucially, enumerates the allowed values for visibility (public, internal, private), which is not present in the schema. This adds significant value beyond the schema. The other parameters are only lightly described but are straightforward.

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 explicitly states the verb 'create' and the resource 'repository', with the scope 'for the authenticated user'. This clearly distinguishes it from sibling operations like update_repository, delete_repository, and _get_repository. The purpose is unambiguous and specific.

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?

The description clearly implies its use for creating a new repository, which is self-evident given the action. It does not explicitly contrast with alternatives like update_repository or delete_repository, but the intent is clear. There is no explicit guidance on when not to use it, but the context makes it obvious.

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