Review a freee monthly attendance application

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

Annotations already supply the read-only, idempotent, non-destructive profile. The description adds genuine behavioral context: the payment-month-to-work-month mapping and the early stop when mapping is ambiguous. That is useful beyond annotations, though it leaves unclear whether stopping means an error or an empty result.

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?

Two focused sentences with no filler. The opening sentence immediately establishes the operation and resource, and the second sentence compactly explains the mapping caveat that governs behavior.

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?

For a single-parameter read-only review tool, the description covers the essential workflow: what is read, what is verified, and when it stops. It doesn't describe the output shape, but with no output schema and a simple review-oriented tool, this is a minor gap rather than a blocking one.

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 single id parameter has 100% schema coverage with a clear description ('numeric No. shown in the freee application list'). The tool description adds no parameter detail, but the schema already carries the semantics, so baseline 3 is appropriate.

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 concrete verb and resource: it reads one exact monthly attendance closure application and enumerates what gets verified (summary, daily attendance, alerts, automatic checks). This clearly distinguishes it from list/status/action siblings even without naming alternatives.

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 gives no explicit when-to-use guidance. It never tells the agent to invoke this before an approval action, nor does it contrast with freee_approval_detail or the monthly prepare/commit tools. The mapping-stop clause is a behavioral condition, not a usage rule.

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