github_codespaces_create_with_repo_for_authenticated_user

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

With no annotations, the description must disclose behavioral traits but only says 'Create a codespace'. It omits side effects (e.g., resource consumption), permission requirements, or the fact that the nested 'body' parameter controls codespace configuration. The name hints at 'authenticated_user', but this is not explicitly stated.

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 sentence, achieving conciseness. However, it is arguably too terse, sacrificing informativeness. It is front-loaded but lacks structure for clarity.

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 complexity (3 params, nested body, no output schema), the description is incomplete. It fails to explain the purpose of the 'body' parameter, the absence of output schema, or the authentication context, leaving significant gaps for the 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 coverage is 100%, so baseline is 3, but the description adds no meaning beyond parameter names. The 'body' parameter is described as 'Request body (JSON object)' in the schema, but the description does not clarify expected fields or structure, reducing its value.

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 'Create a codespace in a repository' clearly states the verb (create) and resource (codespace in a repo), distinguishing it from siblings like create_for_authenticated_user (no repo) and create_with_pr_for_authenticated_user (linked to PR). However, it lacks specificity about repo ownership or prerequisites.

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 is provided on when to use this tool vs alternatives like create_for_authenticated_user or create_with_pr_for_authenticated_user. The agent must infer from the tool name alone, which is insufficient for correct selection.

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