trmnl_unbind_room_booking_collection_device

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

Annotations already declare destructiveHint=true, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description adds the useful nuance that this only stops display (an unbinding, not a deletion), but 'Changes remote state or starts work' is boilerplate that restates the annotations, and it says nothing about what the device shows afterwards or what permissions are needed.

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 purpose is correctly front-loaded in the first sentence and the endpoint follows as supporting evidence. But the trailing 'Changes remote state or starts work. Run only within the user-authorized scope.' is generic filler that could apply to any mutating tool and does not earn its place.

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?

Annotations carry the destructive/idempotent/open-world profile and there is no output schema, so the main obligation is met. Still, for a destructive unbinding operation with a nested path object, the description omits the device's post-unbind state and the profile parameter, leaving real gaps.

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?

With 50% schema description coverage, the description partly compensates by giving the URL template, which disambiguates the three nested path fields (installation_id, id, device_id) by their position and role. However, it says nothing about the optional 'profile' parameter or the special 'url' value accepted for device_id.

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 — 'Stop showing a collection on a device' — plus the exact DELETE endpoint, so the agent knows this removes a collection-to-device association rather than deleting the collection. It does not explicitly name the inverse sibling trmnl_bind_room_booking_collection_device, so differentiation is inferred from the verb rather than stated.

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?

There is no statement of when to use this versus trmnl_delete_room_booking_collection, trmnl_unbind_room_booking_calendar_device, or the corresponding bind tool. The only guidance is a generic safety caution ('Run only within the user-authorized scope'), which is a constraint, not a selection criterion.

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