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

Annotations already mark destructiveHint=true and idempotentHint=true, so the safety profile is partly known. However, the description adds no behavioral context beyond the word 'Complete'—it does not say what changes, whether the action is reversible, or what side effects occur.

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 short and front-loaded, with no filler words. However, it is arguably under-specified for a destructive operation with four parameters, so conciseness comes at the cost of necessary content.

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?

There is no output schema, no parameter descriptions, and the tool is marked destructive. The description does not explain return values, side effects, required parameters, or idempotency semantics, leaving an agent without enough context to invoke the tool confidently.

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 0%, and the description only hints at interviewer_user_id through 'explicit interviewer'. interview_session_id, request_id, and idempotency_key are left entirely unexplained, so the description fails to compensate for the missing schema documentation.

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 names a specific action ('Complete') and resource ('interview session'), with a reference to an explicit interviewer. This is reasonably distinct from sibling actions like start or cancel, though it does not clarify what 'complete' means as a state transition.

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 offers no guidance on when to use this tool versus siblings such as yardstick_interview_sessions_cancel, yardstick_interview_sessions_start, or yardstick_interview_sessions_scorecard_submit. It only implies a target interviewer, not a decision rule or prerequisites.

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