clear_key

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

Annotations cover the safety profile (destructiveHint=false, readOnlyHint=false, idempotentHint=false). 'Staged only' adds genuinely useful context beyond those flags — the removal is not applied until a later apply step — but it does not say what happens to an already-staged change or what the response reports.

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?

Two short sentences, front-loaded with the action and immediately followed by the key behavioral constraint. Nothing is wasted.

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?

An output schema and full-annotations set mean the description does not need to explain return values, and it is adequate for a 3-param tool. The one gap is the staging workflow dependency, which is stated but not explained (which tool applies it).

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 slot/device/profile are fully documented in the schema. The description's 'key or dial' phrase loosely reinforces the slot vocabulary but adds no format or defaulting information beyond it; baseline 3 applies.

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: removing an action from a key or dial. Relative to siblings like set_key and update_key, it is understandable that this clears rather than writes an action, but the description never explicitly contrasts itself with those siblings, so it falls short of a 5.

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?

'Staged only' hints at a workflow but does not say when to use this over set_key/update_key, nor does it name apply_changes or discard_changes as the follow-up. No explicit when/when-not guidance is given.

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