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

The readOnlyHint annotation already establishes this is a safe read. The description adds the useful cap of 'Max 100 per page', but that same limit is already stated in the page parameter's schema description, and nothing is said about auth, sort order, or how multiple filters combine.

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, front-loaded with the capability and filters. The trailing 'IntakeQ: GET /appointments' endpoint reference is marginally useful and slightly redundant with the tool name, keeping it just under a perfect score.

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 an 8-parameter, zero-required list tool with only readOnlyHint as annotation coverage, the description covers the filter surface and pagination limit adequately. It omits how filters combine and default ordering, and with no output schema the return shape is left undocumented, but nothing critical to invoking it 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 all eight parameters (including the status enum and date patterns) are already documented in the schema. The description merely restates the filter categories without adding format/syntax detail, 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?

The description gives a specific verb (Query) plus resource (appointments) and enumerates the five filter axes, so an agent immediately knows this is a filtered list operation. It does not name a sibling such as intakeq_get_appointment to draw the boundary explicitly, so it falls short of 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?

Usage is only implied: the filter list suggests the tool is for browsing/filtering many appointments, which contrasts with the single-record get_appointment sibling. There is no explicit when-to-use, when-not-to-use, or named alternative, so it lands at minimum-viable.

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