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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered; the description adds the non-obvious behavior that the returned link is temporary and expires (pointing at linkExpiration) and that no file bytes are transferred. That is real behavioral context beyond the annotations, though it doesn't mention auth scope or whether the link is single-use.

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?

Three short clauses, front-loaded with the purpose, then the call-site guidance, then the critical caveat ('not downloaded here') before the endpoint. Every sentence carries information an agent would otherwise have to guess.

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 usefully enumerates the returned fields (type, created date, link, linkExpiration), which is exactly what an agent needs to chain into a download. It is close to complete for a one-parameter read tool; only the expiry duration or link lifetime is left unstated.

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 100% and the single file_id parameter is fully documented as a GUID, so the schema carries the burden. The trailing 'GET /v2/files/{id}' confirms the id is a path segment, which is marginal added value; 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?

States a specific verb and resource ('Get a file summary') and immediately enumerates what the summary contains (type, created date, temporary link). The line 'The file itself is not downloaded here' distinguishes it from an actual download/export operation, so an agent knows exactly what this returns.

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?

Names the concrete use cases ('an exported PDF or a form image/signature'), which gives an agent clear trigger conditions and implicitly links to the pdf-export siblings. It stops short of explicitly saying 'use goformz_get_pdf_export for the export record itself', so the routing is inferred rather than spelled out.

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