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

Annotations already declare readOnlyHint=true, so the safety profile is covered externally. The description adds one genuinely useful behavioral note — 'The form content is included' — which warns the agent about heavier payloads, and it enumerates the possible status values. It says nothing about ordering, pagination, or result size, so it adds only modest value beyond the 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?

Two short sentences plus an endpoint reference — front-loaded with the resource and the returned fields, with zero filler. Slightly terse rather than padded, which is the right failure mode here.

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 carries the return-shape burden and does so by listing the key fields and noting that form content is included. Combined with a fully documented 7-parameter schema and a readOnly annotation, an agent has enough to call it correctly; only ordering/default-result-set details are 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 all 7 filter parameters are documented in the schema with precise semantics (id_gt/id_lt paging, patientId, templateId, update date bounds, include_archived default false). The description adds no parameter-level meaning, so the 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?

States a specific resource ('Forms sent to patients') and enumerates the fields returned (title, status, patient, appointment, template, submission time), plus the underlying endpoint GET /patient-forms, which makes the read scope unmistakable. It does not need to differentiate from siblings since no other listed tool returns patient forms, but it also doesn't say so explicitly.

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, no mention of prerequisites or auth, and no exclusions. The only implied usage comes from the schema's filter parameters (patientId, templateId, update dates), which the description never references.

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