complete_auth

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

Annotations are sparse (only readOnlyHint=false, idempotentHint=false), so the description carries the burden. It correctly indicates a write operation completing OAuth, but does not disclose additional behavioral details such as success/failure outcomes, side effects (e.g., storing credentials), or whether the flow can be repeated.

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, well-structured sentence with no unnecessary words. It conveys the essential information efficiently.

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 low complexity (one parameter, no output schema), the description covers the core purpose and input. However, it omits mention of prerequisites (e.g., that 'start_auth' must have been called) and does not describe what happens on completion or error, which would enhance completeness.

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% with the single parameter 'verifier' already described clearly. The description repeats the same information without adding extra meaning (e.g., format, length constraints, or source expectations).

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 'Complete' and the resource 'OAuth 1.0 flow', and includes the specific input (verifier code). It distinguishes this tool from siblings like 'start_auth' and 'check_auth_status' by indicating it is the final step of the authentication process.

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 usage after obtaining the verifier code from an authorization page, but does not explicitly specify when not to use it, mention prerequisites (e.g., 'start_auth' must be called first), or list alternative tools that might be used instead (e.g., 'check_auth_status' for verification).

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