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

With no annotations provided, the description fully carries the burden and does so thoroughly. It discloses the two-step validation flow, the consent text, the confirmation token, and the post-submission email with a click link before any provider sees the enquiry.

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 well-structured with explicit step labels and front-loaded 'NOT a purchase' disambiguation. Every sentence contributes necessary operational detail without wasted words.

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?

Given the complexity of a two-step consent-gated submission and the absence of an output schema, the description is complete. It explains the return values (summary, consent line, token), the required user agreement, and the post-submission email/link behavior, leaving no ambiguity for correct invocation.

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?

Although schema description coverage is 100%, the description adds meaning beyond the schema: answers must be keyed by field keys from enquiry_fields, consent must match the exact consent statement, and confirmation is the token returned in step 1. This clarifies the relationships between parameters and the workflow.

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 Club Grants', and immediately distinguishes itself from a purchase or guaranteed quote. It also references enquiry_fields, clarifying its role relative to a sibling tool that supplies the answer keys.

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 description gives explicit step-by-step instructions: Step 1 calls with answers and consent to get validation, summary and token; Step 2 calls again only if the person agrees, with the same answers, consent, and token. It also states what it is NOT (not a purchase, not a guaranteed quote), preventing misuse.

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