github_codespaces_get_repo_public_key

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

With no annotations, the description must carry the full burden of behavioral disclosure. It only states 'Get a repository public key', which implies a read operation, but does not explain whether it is idempotent, what the response contains (e.g., key_id, key), or any authentication or rate-limit considerations. This is insufficient for an agent to understand the tool's impact.

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, concise and to the point. It contains no redundancy or unnecessary words. However, it could be slightly expanded to include behavioral context without losing conciseness.

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 absence of an output schema, the description should explain what the public key is (e.g., used for encrypting secrets) and what the expected return value looks like. The tool is simple but lacks critical context about its purpose and output, making it incomplete for an agent that might need to use the key subsequently.

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 input schema has 100% coverage with minimal descriptions ('owner', 'repo'), but the tool description adds no additional meaning beyond those field names. It does not explain the expected format or any constraints (e.g., owner must be a GitHub username or org name). The description fails to add value beyond what the schema already provides.

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 'Get a repository public key' clearly states the action (get) and resource (repository public key), but it does not differentiate from similar sibling tools like 'github_actions_get_repo_public_key' or 'github_codespaces_get_org_public_key'. The scope is limited to 'repository', which is helpful, but lacks specificity about the key's purpose (e.g., for encrypting codespaces secrets).

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 versus alternatives such as 'github_actions_get_repo_public_key' or 'github_codespaces_get_org_public_key'. There is also no mention of prerequisites or typical use cases, leaving the agent to infer context from the name alone.

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