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

The annotations already declare readOnlyHint=true, and the description is consistent by describing a pure list/read. It adds the HTTP endpoint as extra context, but says nothing about pagination, filtering, ordering, or the shape of the returned documents, so it stays at 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?

Two short sentences, front-loaded with the action and resource. The trailing endpoint sentence is mildly extraneous but compact and mildly useful for API-level callers.

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 one-parameter read with no output schema, the essentials are present, but nothing is said about how documents are returned (list contents, ordering, limits), which an agent may need. Adequate but with a clear gap.

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?

There is a single parameter documented at 100% schema coverage, so the schema already carries semantics. The description adds nothing beyond restating that documents are scoped to a patient, which is the schema baseline.

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 uses a specific verb+resource ("List the documents uploaded / available for a patient") and names the endpoint, so an agent knows exactly what it retrieves. It is reasonably distinguishable from siblings dealing with FHIR/CCDA/query resources, though it never explicitly contrasts itself with them.

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 particle_get_fhir or particle_get_flat, nor any prerequisites or exclusions. Usage is only implied by the tool name and resource.

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