approve_device_pairing

Idempotent

Approve a pending device enrollment after the account owner independently confirms the 8-digit pairing code shown by the local device. code is the displayed one-time code. Changes trusted device registration; the backend validates account and quota. Do not guess codes.

A4/5.0

Behavior4/5

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

Annotations already convey mutation (readOnlyHint=false), non-destructive, idempotent behavior. The description adds real value beyond them: it states that trusted device registration is changed and that the backend validates account and quota, which the annotations do not disclose.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the action and its precondition, then adds the side effect and a short safety warning. Every sentence carries information; no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter mutation with no output schema, the description covers precondition, side effect, validation, and misuse warning. Return format is unspecified but largely inferable for a confirmation-style call.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must carry the parameter, and it does: 'code is the displayed one-time code' tied to an 8-digit value shown by the local device. This adds origin and format meaning the bare 'Code' schema title does not.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Approve a pending device enrollment') with the input it consumes (an 8-digit pairing code). It is clearly distinct from read-oriented siblings like list_devices or setup_* tools, though it never names a sibling explicitly.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives a concrete precondition ('after the account owner independently confirms the 8-digit pairing code shown by the local device') and an explicit caution ('Do not guess codes'). It lacks an explicit when-not/alternative clause, but the prerequisite is strong enough to guide invocation.

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