bluetooth_disconnect

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

With no annotations, the description carries full burden for behavioral disclosure. It reveals that an empty MAC disconnects all devices, but it does not disclose other behaviors like error handling, permissions required, or impact on connected devices. This is insufficient for a mutation tool.

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 with no wasted words. The '[ACTION]' prefix is a minor redundancy but does not harm conciseness. It is front-loaded with the core action and parameter behavior.

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 single-parameter tool with an output schema, the description covers the basic purpose and the notable empty-MAC behavior. However, it omits prerequisites (e.g., Bluetooth adapter on) and error conditions. It is adequate but not fully comprehensive.

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%, so the description must compensate. It explains that an empty MAC string means all devices will be disconnected, adding meaning beyond the schema's type and default. However, it does not specify the expected MAC format (e.g., colon-separated hex) or any constraints, leaving room for ambiguity.

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 'Disconnect' and the resource 'Bluetooth device'. It distinguishes from siblings like bluetooth_connect, bluetooth_pair, and bluetooth_scan by being the only disconnect tool. The additional note about empty MAC adds specificity.

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 is provided on when to use this tool versus alternatives such as bluetooth_connect or bluetooth_pair. The description does not mention when not to use it or provide context for choosing it over other Bluetooth tools.

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