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

Beyond the annotations, it discloses the server holds no keys and no funds, the call is free, and the response returns the recorded intake id and derived Regen account. The caveat 'It is recorded, not accepted' clarifies the postcondition and distinguishes acceptance from recording, which annotations don't convey.

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?

Four sentences front-load the essential instruction (pass unchanged body and signature) before giving endpoint/trust, return value, and the follow-up caveat. Every sentence contributes either an action, a prerequisite, or a behavioral postcondition.

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?

With only two fully documented parameters, an output schema, and safety annotations, the description covers the full sequence: source (prepare_place), signing prerequisite, HTTP endpoint, server trust, returned data, and post-submission monitoring via place_status. No critical gap for invoking the tool correctly.

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 100% and both parameter descriptions already specify 'exact BODY_JSON from prepare_place, unchanged' and the 0x personal_sign output over MESSAGE_TO_SIGN. The prose adds workflow framing but no substantive parameter details beyond the schema.

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 verb+resource: complete the signed place intake by passing BODY_JSON and signature to POST /labor/place/intake. It explicitly positions itself as 'step 2 of 2' relative to prepare_place and is distinguished from the sibling place_status by saying the intake is recorded, not accepted.

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 says to use this only after prepare_place has produced BODY_JSON and MESSAGE_TO_SIGN, and after the wallet signs MESSAGE_TO_SIGN. It directs the agent to monitor the result with place_status, implicitly separating submission from acceptance. It does not, however, spell out an explicit 'do not use before signing' exclusion.

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