List my appointments

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

With no annotations, the description provides transparency on the behavioral constraint of listing only upcoming, non-cancelled appointments. It also implies the need for authentication ('signed-in client'). No mention of pagination or error cases, but given simplicity, it's adequate.

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?

Single sentence, no filler. Every word adds value.

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?

Given zero parameters and no output schema, the description is mostly complete. It doesn't define 'upcoming' time range, but the simple nature and sibling tools provide enough context.

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?

Tool has zero parameters with 100% schema coverage. Baseline for 0 params is 4. Description adds no parameter details but none are needed.

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 clearly states the verb 'list' and the resource 'appointments', with specific constraints: 'signed-in client's upcoming (non-cancelled)'. This distinguishes it from sibling tools like 'find_availability' and 'list_providers'.

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 when to use (to see one's own appointments) but lacks explicit guidance on when not to use or alternatives. For example, no mention that cancelled appointments are excluded, which is a key differentiator.

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