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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description adds genuine value by enumerating the record fields returned (scheduled date, duration, status, reason, patient, physician, service location) and mapping to the upstream API (GET /appointments/), but says nothing about pagination defaults, rate limits, or auth.

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, front-loaded with the core capability followed by the returned fields and endpoint note. Every sentence carries information, though the trailing 'Elation: GET /appointments/.' is only marginally useful to an agent choosing a tool.

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 compensates well by listing the fields each record carries, and the 100%-covered input schema handles parameter details. It is nearly complete for a read-only list tool; only pagination behavior expectations (cursor vs offset default) are left entirely to the schema.

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 the schema already documents all nine parameters with types, ranges and formats. The description restates four filter dimensions (date range, patient, physician, practice) but adds no format or interaction guidance beyond the schema, so it sits at the 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?

States a specific verb and resource ('List appointments and calendar time slots') and enumerates the filter dimensions and returned fields, so the scope is unambiguous. It does not explicitly differentiate itself from siblings like elationhealth_get_appointment or elationhealth_list_appointment_types, but the list-vs-single distinction is inferable.

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 description implies usage through 'filterable by date range, patient, physician and practice,' which tells an agent how to narrow results, but never states when to prefer this tool over elationhealth_get_appointment or when a filter is required. No exclusions or prerequisites are given.

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