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

The description adds real context beyond annotations: on the hosted server the document is retained 30 days so short links work and anyone with a link can open it, while elsewhere the payload travels in the URL fragment and is stored nowhere. That explains the privacy/persistence trade-off and implicitly why readOnlyHint is false; it does not mention auth requirements or rate limits, keeping it from a 5.

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 output is front-loaded ('Links to a document:') and every clause carries information about link types or hosting behavior. The nested parenthetical listing editor capabilities is slightly dense but not wasteful.

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 an output schema present, return values need not be explained, and the single parameter is covered by the schema. The description fills the remaining gap that matters — where the document lives and who can open it. Only failure behavior for a malformed document is unaddressed.

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 'document' parameter is fully documented in the schema, including accepted forms and the producing tools. The description only says 'a document', so it adds nothing beyond the schema; baseline 3 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?

The description states a concrete output: a viewer_url that opens the document in the uniwire web editor and a pdf_url for the drawn PDF. The resource (a document / electrical installation) is specific enough to distinguish it from siblings like render or validate, though it never explicitly names a sibling for contrast.

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?

Usage is only implied: the reader infers this is the tool to call when they need a shareable link or a PDF rather than a rendered image. There is no explicit when-to-use statement, no exclusion naming render or normalize as alternatives, and no prerequisites stated.

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