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

No annotations are provided, so the description carries the full burden and does so: it discloses that step 1 validates and returns a summary/consent line/token, that the enquiry is only submitted on the second call, that the person must click an emailed link before any provider sees the data, and it spells out the exact consent text. This is unusually rich disclosure for a mutation tool.

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 distinction (not a purchase) and then sequenced in call order, so every sentence does work. It is on the long side because it embeds the full verbatim consent text, which is justified but makes the block dense; a slight trim of the embedded quote would help readability without losing information.

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-call write tool with no output schema, the description covers the whole lifecycle: validation, what is returned at each step, the consent gate, the email-confirmation step, and the downstream disclosure to up to three providers. Nothing an agent needs in order to call it correctly at either step 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%, so the baseline is 3, but the description adds real semantics beyond the schema: 'answers' is keyed by the field key from enquiry_fields, 'consent' must be true only after the person agreed to the quoted text, and 'confirmation' is the token returned by step 1 and only used after the person approves the summary. The flow-level meaning of each parameter is not derivable from the schema alone.

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 NEBOSH Course Cost') and immediately negates the two most likely misreadings ('NOT a purchase, NOT a guaranteed quote'). An agent can distinguish it from enquiry_describe/enquiry_fields, which are clearly read-side discovery tools.

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 an explicit two-step protocol with the exact conditions for each call: step 1 with answers + consent=true, step 2 only if the person agrees, with the same answers plus the confirmation token. When-not-to-proceed is stated ('only if the person agrees') and the human-approval gate is unambiguous.

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