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

Annotations flag it as a non-read-only, non-idempotent write, and the description usefully clarifies that no charge occurs ('does not charge the buyer') and that the qualification is 'sealed before payment'. It also discloses the concrete return artifacts (payment endpoint, order token, terms, status URL), adding context annotations cannot convey.

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?

Three sentences, front-loaded with the core action and consequence, with each sentence adding a distinct fact (sealing, no charge, return payload). No redundant filler, though it is slightly dense.

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?

Annotations cover the safety profile and there is no output schema, so the description correctly describes what is returned. However, given 0% parameter coverage and nested required objects, an agent still lacks guidance on how to populate the inputs, leaving a real completeness gap.

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 description coverage is 0% across 5 parameters, including nested objects (opportunity, company_profile) and an enum (pursuit_role), and the description explains none of them. With the schema carrying no parameter documentation, the description needed to compensate and does not.

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?

Strong verb+resource: 'create ... order for a machine-readable federal opportunity qualification,' and the '$5 unpaid' framing distinguishes it from the sibling 'qualify_federal_opportunity_free'. It stops short of explicitly naming that free sibling as the alternative, but an agent can still tell the two apart from the text.

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 line 'so an authorized buyer agent can decide whether to pay' implies the intended caller and context, but there is no explicit when-to-use-vs-'qualify_federal_opportunity_free' guidance or stated preconditions. Usage is inferable, not spelled out.

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