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

With no annotations provided, the description carries full responsibility and meets it. It discloses that the operation is not a purchase, requires consent, validates input, returns a summary and consent line, sends an email with a clickable link, and explains the two-step nature. It also quotes the exact consent wording.

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 detailed but every sentence serves a purpose. It is front-loaded with the core purpose and exclusions, then walks through the steps in a logical order. No redundancy or filler.

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-step tool with consent and confirmation requirements, the description covers all necessary information: validation, summary display, consent line, token usage, email notification, and the condition for proceeding. No output schema is needed because the description explains what to expect.

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 baseline is 3. The description adds context beyond the schema: answers must be keyed by field key, consent must be true only when the person agrees to the quoted consent line, and confirmation is the token from step 1. This clarifies the relationship between parameters and the two-step flow.

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 and resource ('Submits an enquiry to HACCP Software Compare') and immediately clarifies what it is not ('NOT a purchase, NOT a guaranteed quote'), distinguishing it from sibling comparison tools. The two-step process is also outlined clearly.

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?

Provides explicit step-by-step usage: first call without confirmation, then second call only if the person agrees. It specifies the consent condition and the need for a confirmation token. No alternative tools are mentioned, but the context is unambiguous and the tool's role is fully specified.

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