bluetooth_pair

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

No annotations are provided, and the description does not disclose side effects (e.g., modifying system state, requiring permissions). It states 'Pair' without explaining consequences like storing pairing keys.

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 a single sentence, but the '[ACTION]' prefix is unnecessary and adds noise. It could be trimmed to 'Pair (and optionally trust) a Bluetooth device.'

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?

Despite having an output schema, the description does not mention return values or error conditions. For a tool that likely has side effects, more context (e.g., pairing result, timeout) is expected.

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 0%, and the description adds no parameter-level details. 'mac' is not explained (e.g., format), and 'trust' default is true but meaning unclear. The description only says 'optionally trust' without elaboration.

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 action (Pair) and resource (Bluetooth device), and mentions optional trust. It differentiates from siblings like bluetooth_connect by focusing on pairing, not connecting. However, it starts with '[ACTION]' which is extraneous.

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 guidance on when to use this tool versus alternatives like bluetooth_connect or bluetooth_devices. The description does not specify prerequisites (e.g., device must be discoverable) or situations where trust is needed.

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