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

Annotations already establish the safety profile (readOnlyHint, idempotentHint, destructiveHint=false), so the description is free to add value elsewhere — and it does, by disclosing the full shape of the returned record and pointing to the `say` field for a readable summary. This meaningfully compensates for the absent output schema, though it says nothing about error behavior for an unknown id.

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?

Front-loaded with the core statement ('One application in full') followed by a compact inventory of contents. Three sentences with little waste, though the enumeration is a touch list-like rather than prose.

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?

With no output schema, the description carries the return-value burden well by naming the fields an agent will receive, and the `say` pointer closes the 'where is the summary' gap. Missing only edge-case behavior (invalid/missing application_id) for full 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?

Single parameter with 100% schema description coverage, including the hint that the id comes from prepare_application or list_applications. The description adds no further parameter detail, so the baseline of 3 for schema-does-the-work applies.

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?

States a clear verb+resource and goes further by enumerating the payload (tailored CV, cover letter, answers, revision number, download links), so an agent knows exactly what a full application record contains. It distinguishes itself implicitly from list_applications by scoping to 'one' application, but never names the sibling tools it should be preferred over.

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?

There is no explicit when-to-use or when-not-to-use guidance, and no named alternatives among siblings such as list_applications, application_progress, or edit_application. The phrase 'what the person reviews before applying' describes the artifact's role, not a condition that selects this tool.

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