complete_pairing

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It frames completion of a pairing mutation but says nothing about required permissions, whether an existing pairing is replaced, what happens on an invalid code, or whether the operation is reversible. This is a notable gap for a mutation-style action.

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 front-loaded sentence that communicates the action, target, and required input context with no filler. It is properly sized and prioritized.

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 has only two required parameters, no output schema, and no annotations, the description provides the core invocation context but misses important surrounding context like postconditions, failure modes, or how this step relates to an ongoing pairing workflow.

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 schema has zero description coverage, so the description must compensate. It does add meaning by saying the device is 'a discovered device' (mapping to deviceId) and that code comes 'shown by the appliance' (mapping to code). It does not explicitly restate the parameter names or formats, but for two simple required parameters this is adequate.

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 states a specific action ('Complete'), a specific resource ('consumer pairing'), and a specific scenario ('for a discovered device', 'using the code shown by the appliance'). This clearly distinguishes it from siblings like pair_device, remove_pairing, or discover_devices.

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 the tool: after a device has been discovered and after the appliance displays a code. It doesn't explicitly exclude uses or name alternatives, but the context is clear enough for an agent to select it over discovery or device-listing tools.

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