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

Beyond the readOnlyHint and idempotentHint annotations, the description adds non-obvious behavior: the download endpoint re-checks access and revision gates, and the tool does not approve, send, or submit. These side-effect disclosures are genuinely useful and do not contradict any annotation.

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 sentences with no filler: the core purpose comes first, followed by the review-copy caveat and the explicit non-behaviors. Every sentence contributes a distinct, useful fact.

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 one-parameter tool with strong annotations and no output schema, the description explains what is returned (an authenticated link), the precondition, the access/revision re-check, and what the tool does not do. Failure cases and link expiration are not covered, but nothing essential for invoking it correctly is missing.

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 only parameter, jobId, is never explicitly explained in the description; 'existing generated file' implies it references a prior generation job but does not directly connect the term. With 0% schema description coverage, the description should have compensated more explicitly. The parameter's self-evident name keeps this from being lower.

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 the exact deliverable — an authenticated link — and the resource, an existing generated file. It explicitly negates approve/send/submit behavior, which helps separate this tool from export/produce siblings. The review-copies-only clause further narrows scope.

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 clearly says this tool is for obtaining download links for already-generated files and explicitly warns against using it to approve, send, or submit. It also flags historical dossiers and presentations as review copies only. However, it names no alternative sibling tool, so routing guidance stops just short of explicit.

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