create_repository

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

With no annotations provided, the description carries the full behavioral disclosure burden. It clearly communicates that this is a mutating create operation scoped to the user's namespace, but it does not disclose potential side effects, permissions needed, default visibility/README behavior, or error cases like name conflicts.

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, front-loaded sentence with no filler or redundant phrasing. Every word contributes to stating what the tool does.

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 tool is simple and the schema fully documents parameters, but there is no output schema and no annotations. The description does not mention what the tool returns, how conflicts are handled, or any prerequisites, so an agent is left with some uncertainty about expected outcomes.

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 all four parameters are already documented in the schema. The description adds minimal extra meaning beyond 'your namespace' slightly clarifying where the project is created, but it does not elaborate on defaults or parameter interdependencies.

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 states a specific action, 'Create', and a specific resource, 'a new GitLab project in your namespace'. This clearly distinguishes it from sibling tools like create_merge_request, create_branch, and fork_repository, which target different resources.

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 implies the tool is for creating a new project, but it does not provide explicit guidance on when to choose this over related tools such as fork_repository or search_repositories. No exclusions or alternative routing are mentioned, so the agent must infer usage from the name and context.

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