TDQS

A4.1/5.0

Behavior4/5

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

Annotations declare a non-read-only, non-idempotent, non-destructive mutation but say nothing about effects. The description adds substantive scope limits: it does not reserve funds and does not launch processing, which tells the agent the mutation is limited to quote/status refresh. It stops short of describing behavior on a non-expired or already-started project.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, front-loaded with the purpose, followed by workflow guidance and scope limits. Nothing is redundant or padded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need no explanation, and the description covers purpose, eligibility, workflow sequencing, and mutation limits. It leaves out error/precondition-failure behavior, the only real remaining gap for a single-parameter mutation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and the only parameter, project_id, is undocumented in both places. The description partially compensates by constraining the valid domain to expired, unstarted projects, which meaningfully narrows which project_id is acceptable, though it adds nothing about the identifier's format or lookup.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Refresh an expired, unstarted project's quote and status') with a clear eligibility precondition. It implicitly separates itself from start_karaoke/prepare_karaoke by declaring it does not launch processing, though no sibling is named.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives concrete when-to-use conditions ('expired, unstarted project') and a workflow instruction ('Show the returned terms before starting'), which implies the hand-off to start_karaoke. It does not explicitly state when not to use it or name alternatives like retry_karaoke or prepare_karaoke.

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