Get File By Its UUID

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

The description adds behavioral context beyond annotations by noting that it either gets binary content from local disk or redirects to remote storage. Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, so no contradictions. The description provides value by explaining the redirect behavior.

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 two sentences covering behavior and usage recommendation. It is efficient and front-loaded with the core action. Could be slightly more structured, but it earns its place.

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?

The description covers the basic purpose, required parameter, and behavior, but lacks details on the output structure (only says 'JSON object describing the requested Documents') and does not explain the pagination parameters in context. Acceptable but not comprehensive.

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%, so baseline is 3. The description mentions 'Required parameters: uuid' but adds no further semantics. The purpose of 'page' and 'per_page' in a single-file retrieval is unclear; the description does not clarify this potential confusion.

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 tool fetches binary file content or redirects to a remote service, identified by UUID. It mentions the endpoint and required parameter. However, it does not differentiate from siblings like other 'get' tools for files, so it's not a 5.

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?

The description says 'Use this to fetch the full details of a specific Documents by its identifier', but provides no guidance on when to use this tool versus alternatives, nor any exclusions. No mention of when not to use it.

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