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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds that it returns file metadata and download URLs, which is useful context beyond the annotations. However, it does not mention pagination, error behavior, or any edge cases, so it adds moderate value relative to the annotation baseline.

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 a single, front-loaded sentence with no filler. It efficiently communicates the verb, resource, and output contents, making it easy to parse quickly.

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 simple list tool with one parameter and no output schema, the description is mostly complete: it states what is returned (metadata and download URLs). However, it omits details like whether the list is paginated or if all attachments are returned at once. Given the annotations cover safety, this is adequate but not thorough.

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%, so the description must explain the 'id' parameter. It only implies that 'id' is the application identifier through the phrase 'an application's attachments', but does not explicitly state that the 'id' is the application ID, nor does it give any additional format or constraints. This is insufficient to fully compensate for the lack of 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 clearly states the verb 'List', the resource 'an application's attachments', and specific output content ('with file metadata and download URLs'). This distinguishes it from other list tools like 'hires_list_candidate_files' which focus on candidate files rather than application attachments.

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 guidance on when to use this tool versus alternatives such as 'hires_download_attachment' or 'hires_upload_application_attachment'. No mention of prerequisites, exclusions, or contextual conditions. The description is purely functional with no routing help.

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