Delete device

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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered. The description adds one genuinely useful behavioral fact — reminders stop — but says nothing about auth requirements or whether removal is reversible. With annotations carrying the core disclosure, a 3 fits.

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?

One short sentence, front-loaded with the verb and resource, zero filler. It is efficient, though the very brevity is part of why parameter and usage detail are absent.

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 simple destructive delete whose annotations already cover safety, the description conveys the action and its effect, so an agent can proceed. The gap is the undocumented token parameter and absent guidance on alternatives; no output schema exists, so return values need not be explained.

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?

The single 'token' parameter has 0% schema description coverage, and the description never mentions how the device is identified or what form the token takes. For a 1-param tool where the schema does no explanatory work, the description should compensate but does not.

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 concrete verb and resource ('Remove a device') and adds the observable consequence ('stops receiving reminders'), which distinguishes it from add_device, list_devices, and the delete_session/delete_step siblings. It does not explicitly name a sibling, but the resource is unambiguous.

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?

No when-to-use, when-not-to-use, or alternatives are given. Nothing tells the agent that list_devices or add_device are complements, or under what conditions deleting (vs. disabling) a device is appropriate.

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