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

Annotations already mark the call destructive and idempotent, and the description enriches this with concrete effects: the slot is released ('Termin wird freigegeben'), Claimondo is notified, responses are PII-free, and repeated calls are harmless because an already-cancelled appointment is not changed again. It also states the authorization requirement via the token.

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?

The action is front-loaded in the first sentence, and each subsequent block earns its place: trigger condition, token authorization, effect, reschedule flow, parameter recap, safety notes. Despite length, there is no filler.

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 destructive, authorization-gated tool, the description covers everything needed to call it correctly: who must supply the token, what happens on cancellation, idempotency, PII behavior, and the follow-up route for rescheduling. An output schema exists, so return-value details are not required here.

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 coverage is 100% and both parameter descriptions are already detailed, so the description adds little beyond the schema. It does frame the token as 'die Autorisierung' and repeats the no-guessing rule, but this is reinforcement rather than substantial new meaning.

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 opening sentence states the exact operation: 'Sagt einen bereits gebuchten Kfz-Gutachter-Termin bei Claimondo ab'. It also resolves the title's 'oder verschieben' by explaining that moving an appointment is done by cancelling here first and booking elsewhere.

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?

It gives an explicit trigger condition: 'Nutze dieses Tool, wenn ein Kunde sagt, dass er seinen Termin nicht wahrnehmen kann...' and directs to alternatives for the follow-up booking: the Claimondo link or 'claimondo_finde_gutachter_termine'. This tells the agent when and when not to use it.

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