create_repository

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It adds some context by noting the repository is empty and pushable via git, but this is potentially misleading because the schema supports templateProject and readMeType, which would make the repository non-empty. It also omits side effects, permission requirements, duplicate handling, and response behavior.

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 short and front-loaded with the core purpose. The 'Use Cases' line is redundant and adds little value, but overall the description avoids unnecessary verbosity and is easy to scan.

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?

Despite having 9 parameters and no output schema or annotations, the description only covers the basic creation scenario. It fails to mention important behaviors like template-based creation, README auto-generation, visibility options, or what happens after creation. This leaves significant gaps for an agent deciding whether and how to invoke the 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?

Schema description coverage is 100%, so the schema already documents all 9 parameters. The description adds no additional parameter-level meaning beyond the schema, but it does not need to compensate for missing schema coverage. Baseline 3 is appropriate.

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'), the resource ('Codeup repository'), and the intended result ('empty code repository that can then be pushed to via git'). It distinguishes this tool from sibling tools like get_repository, list_repositories, and create_branch by focusing on repository creation.

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 'Use Cases' section is generic and tautological ('Create a new repository for a project'), providing no guidance on when to prefer this tool over alternatives or when not to use it. There is no mention of prerequisites, such as needing an organization or namespace, nor any contrast with related repository tools.

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