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

annotations already declare readOnlyHint=true, so the safe-read profile is covered. The description usefully adds the pagination cap ('Max 100 per page') and the underlying endpoint, which is context beyond the annotations, but it says nothing about default sort order or what happens when no filters are supplied.

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?

Three short sentences, filter capabilities front-loaded, pagination constraint second, endpoint reference last. No filler and nothing buried.

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 read-only list tool with full schema coverage and no output schema, the description covers filters, pagination and identity. It could note whether results are sorted or what an unfiltered call returns, but nothing essential to correct invocation is missing.

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 every parameter is already documented with type, pattern and enum. The description's filter list largely restates what the schema provides, so it adds no syntax or default-value information 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?

States a specific verb (Query) and resource (appointments) and enumerates the filterable dimensions, which distinguishes it from intakeq_get_appointment or intakeq_create_appointment. It stops short of naming any sibling explicitly, so it is clear but not sibling-routing.

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 implied by the filter list – you call it to search/filter appointments rather than fetch one. There is no explicit when-to-use, no when-not-to, and no pointer to intakeq_get_appointment for a single record, so the agent must infer the choice.

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