Remove tag from devices

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and idempotentHint=true, covering the safety profile. The description adds the endpoint URL and clarifies that the action removes the tag from provided devices, implying the tag itself is not deleted. However, it does not elaborate on side effects or authorization requirements, which would be useful beyond the annotations.

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 description is short but repetitive. The first sentence ('Remove tag from devices') essentially repeats the title, and the second sentence adds minimal new information. The endpoint line is useful but could be integrated more concisely. Overall, it is structured clearly but not exceptionally efficient.

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 the tool's simplicity (2 parameters, no output schema) and the presence of annotations covering idempotency and destructiveness, the description is mostly adequate. However, it could be more complete by explicitly stating that the tag itself is not deleted and possibly mentioning that repeated calls are idempotent, though the latter is covered by the idempotentHint annotation.

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%: both parameters ('id' and 'device_ids') have clear descriptions. The tool description adds no extra parameter-level semantics beyond what the schema already provides, so the baseline score of 3 is appropriate.

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 tool's function: removing a tag from specific devices. It effectively conveys the action on a resource ('tag from devices'), and the scope is distinct from sibling operations like 'deleteTag' (which deletes the entire tag) and 'tagDevices' (which adds tags). However, it does not explicitly name these alternatives to differentiate itself.

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 this tool—when you want to remove a tag from certain devices—but it does not provide explicit guidance on alternatives, such as 'deleteTag' for deleting the tag entirely or 'tagDevices' for the inverse operation. No exclusions or when-not-to-use guidance is given.

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