accept_pairing

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

With no annotations, the description carries the full burden of behavioral disclosure. It mentions a backend requirement but does not explain side effects, success/failure outcomes, authorization needs, or what happens to the pairing state. The action 'accept' implies mutation, but no details are provided about its consequences.

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 extremely concise, consisting of a single sentence with two clauses. It front-loads the core action and includes the key differentiator (mobile-initiated) and a prerequisite. There is no wasted text, though it is so brief that it borders on under-specification.

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 is a state-changing action with no annotations and only one parameter, the description is inadequate. It omits error handling, return behavior (despite having an output schema), and any edge cases. An agent could not fully assess the impact of calling this tool.

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 does not elaborate on the meaning of 'device_id' beyond the schema's minimal 'Device Id'. It does not clarify that it identifies the device whose request is being accepted, nor any format or constraints. The description adds no value to the parameter understanding.

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 verb ('acepta') and the resource ('solicitud de emparejamiento entrante'), and explicitly notes it is initiated by the mobile, which distinguishes it from sibling tools like request_pair and reject_pairing. An agent can immediately understand what action this performs and when it applies.

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?

It specifies that the request is incoming (initiated by the mobile), which implies it should be used for accepting rather than initiating pairing. It also mentions a prerequisite ('Requiere backend kcd'), giving a concrete condition for use. However, it does not explicitly contrast with reject_pairing or state when not to use it.

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