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

With no annotations provided, the description carries the full behavioral burden, and it delivers: it explains validation, the returned summary/confirmation token, the condition for step 2, the email link requirement, and the exact consent wording. It also clearly states that this is not a purchase or guaranteed quote, which prevents misuse.

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?

The description is dense but efficiently structured: the non-purchase warning comes first, then Step 1 and Step 2 are clearly separated, and the consent text is included because it is essential. No sentence is padding, and the title adds useful context rather than repeating the description.

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?

There is no output schema, but the description explains what step 1 returns (summary, consent line, confirmation token), what to show the person, what step 2 returns (submission plus an email link), and the condition for proceeding. For a two-step tool with consent requirements, this is complete enough for an agent to call it 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%, so the baseline is 3. The description adds value by explaining the step-dependent role of the confirmation token, requiring the same answers in step 2, and tying answers to enquiry_fields. The consent parameter's meaning is largely already in the schema, so this is strong but not a 5.

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 names the specific operation, 'submits an enquiry to Payroll Software Compare,' and immediately disambiguates it from a purchase or a guaranteed quote. The title's 'two steps; not a purchase' further reinforces what this tool is for, making it clearly distinct from comparison-focused siblings.

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 two-step workflow is precisely specified: call once for validation and a confirmation token, then call again with that token only after the person agrees. It also references enquiry_fields for answer keys. It does not explicitly contrast this tool with the compare_* siblings, but the submit-vs-compare distinction is clear enough that this is a minor gap.

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