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

No annotations are supplied, so the description carries the full behavioral burden and does so thoroughly: validation happens first, step 1 is non-submitting and returns a summary plus consent line and token, submission only occurs on step 2, and the person must click an emailed link before any provider sees the enquiry. The exact consent text and its scope (up to three engineers, each name emailed, ability to stop) is disclosed.

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?

Front-loaded with the key negative framing and the two steps, and every sentence carries operational weight. It is a dense single block, though, and the long verbatim consent quotation plus repeated consent references could be broken into clearer steps or bullets.

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?

For a two-phase, nested-object mutation with no output schema, the description still tells the agent what step 1 returns (summary, consent line, confirmation token) and what happens after step 2 (email, link click, provider visibility). Nothing essential for calling it correctly in either phase is missing.

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 the schema already documents answers as keyed by field key, consent as the agreement flag, and confirmation as the step-1 token. The description restates these relationships and adds the useful ordering constraint that the token comes only after approval, but it introduces little meaning the schema does not already carry.

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 ('submits an enquiry to Cold Room Installation Cost') and immediately negates two common misreadings ('NOT a purchase, NOT a guaranteed quote'). It ties itself to the sibling it depends on by naming enquiry_fields as the source of the field keys, so the agent can distinguish it from enquiry_describe and enquiry_fields without opening a schema.

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?

Gives exact when-to-call instructions for both phases: step 1 with answers plus consent=true, step 2 only after the person has approved the summary and with the returned token. It also states what this tool is not, which steers the agent away from treating it as a checkout or quote-issuing action.

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