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

readOnlyHint=true already establishes the safe-read profile, so the description's additional disclosure that the response includes every question and answer plus the linked appointment is genuinely useful. However, nothing is said about permissions, error behavior when the id is invalid, or pagination/size limits.

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 tight sentences with the payload contents front-loaded. The trailing 'IntakeQ: GET /notes/{id}' is slightly redundant with the tool name but cheap and mildly useful for endpoint mapping.

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?

A single-parameter read tool with an annotation and no output schema, where the description covers both the input (via schema) and the returned payload shape. Only the absence of failure/auth behavior keeps it short of a 5.

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 one parameter and schema coverage is 100% with its own description ('The note's id (a GUID)'), so the schema fully documents it. The description adds no format or sourcing detail beyond the schema, which matches the baseline 3 for fully covered parameters.

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 verb (Fetch) and resource (one treatment note) and explicitly scopes it to a single record with its Q&A and linked appointment, which clearly separates it from intakeq_list_notes.

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 word 'one' implies the single-record counterpart to list_notes, but the description never names the alternative or states when to prefer this over listing or get_intake. Usage is only implied.

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