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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false, so the safety profile is partly covered. The description adds useful behavior beyond annotations: it preserves the original format and returns URLs (plus a ZIP for multiple forms), and it explains that submission happens outside the tool. It does not explain why the operation is not read-only or any auth/size caveats.

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 sentences, front-loaded with the action and output, followed by the user-facing workflow note. No filler, though the second sentence is a bit tangential to selecting/invoking the tool.

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?

An output schema exists, so return-value explanation is not strictly required, and the safety profile is covered by annotations. The description adequately frames the export workflow but leaves both parameters entirely undocumented, which is the main completeness gap for a 2-param tool.

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 there are two parameters (case_id required, form_ids optional array) that the description never mentions. With no schema text and a purely non-compensating description, an agent gets no meaning for either parameter.

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 states a specific verb (出力/export) and resource (記入済みの様式, the completed forms) and even describes the output (download URL, ZIP when multiple). An agent can tell it produces downloadable artifacts. It stops short of differentiating itself from the close sibling validate_and_export_application.

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?

It gives post-invocation workflow guidance (show the URL, tell the user to verify formatting/missing entries/attachments before submitting, submission is the user's job), which implies the tool is a final-step export. However, it never states when to choose this over validate_and_export_application or validate_application, so the alternative-routing guidance is absent.

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