TDQS

C2.7/5.0
Behavior2/5

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

Annotations already tell the agent this is a non-read-only, non-idempotent, open-world mutation. The description adds only 'Needs key', which is a useful auth hint, but says nothing about what accepting actually does (e.g., mutual identity/contact reveal), whether declining is reversible, whether a 'proof' is required for yes, or what happens on repeated calls despite idempotentHint=false.

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?

Two short sentences with the action front-loaded and no filler. It is tight, but the brevity is partly under-specification rather than disciplined editing, so it doesn't quite reach 5.

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

Completeness2/5

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

A 4-parameter mutation tool with no output schema and 0% schema coverage needs considerably more: the description never explains what a yes/no response produces, whether 'proof' gates success, or what the 'key' credential is. The sparse annotation set covers safety hints but not the interaction contract.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must carry the load, but it only alludes to 'key' — and even that conflicts mildly with the schema, which lists 'key' as optional while 'id' and 'yes' are required. The meaning of 'id' (which intro request) and especially 'proof' (what it is, when required) receives no explanation at all.

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: responding yes/no to an introduction request made by another agent. It is clearly distinguishable from sibling 'intros' (which presumably lists requests) and 'introduce_me' (which initiates one), though the description never names those siblings to reinforce the distinction.

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

Usage Guidelines2/5

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

There is no explicit guidance about when to call this versus 'intros' (to find pending requests) or what to do if the request is stale. 'An introduction another agent asked of you' implies the situation but leaves all routing and prerequisite decisions to inference.

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