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

With no annotations the description carries the full load, and it does disclose the key side effects: a job is created, a pay link is conditionally returned based on whether the shop requested a deposit, and other shops are notified the job went elsewhere. It stops short of stating reversibility (can the pick be undone?), idempotency, or what happens on an expired/already-picked reply.

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?

Three short sentences, front-loaded with the action, then the committed outcome, then the side effect on other shops. No filler and no repetition.

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?

An output schema exists so return values need no explanation, and the description does flag the conditional pay link. But for an unannotated, irreversible-looking award action, it omits preconditions, failure modes (reply already used, request withdrawn), and whether other replies must exist first.

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?

Three parameters at 0% schema description coverage, and the description names none of them. 'One shop's reply' loosely implies reply_id, and 'the job' implies request_id, but the phone parameter is entirely unaccounted for and no format, constraint, or selection rule is given.

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?

States a specific verb and resource ('Book one shop's reply') plus the concrete outcome: a job is created with that shop, a deposit pay link may be returned, and competing shops are notified. This is clearly distinguishable from homeowner_getRequest, homeowner_listRequests, network_reply and network_decline.

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 context of use is implied — an agent can infer this is the selection step after shops have replied — but there is no explicit 'use when', no preconditions (must the request still be open? must the reply be live?), and no named alternative for declining or withdrawing.

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