oauth_callback

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

No annotations are provided, and the description discloses zero behavioral traits. It does not mention side effects (e.g., creating a session), required auth state, or what happens on success/failure. This is a critical gap for a tool likely involved in authentication.

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 (two lines), but at the cost of missing essential information. It earns its place in terms of brevity but fails to convey meaning, so it is not appropriately sized for the information needed.

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 simplicity of the input schema and no output schema, the description still lacks completeness. It does not explain the purpose, expected behavior, or context of use. A two-line description is insufficient for a tool involved in OAuth flow.

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 no parameters, and schema description coverage is 100% (since there are no params). The description adds no parameter information, which is acceptable given no params exist. However, it could explain that the callback receives query parameters from the OAuth provider, but the agent need not pass them. Baseline for 0 params is 4.

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 'Oauth Callback [GET /api/auth/oauth/callback]' is vague and does not clearly state the tool's purpose. It only provides a title and HTTP method/route, lacking an explicit action like 'Handles the OAuth callback from an external provider to complete authentication.' This is insufficient for an agent to understand its role.

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. The sibling 'oauth_login' exists, so context on when to invoke the callback versus initiating login is critical, but entirely absent.

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