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

With no annotations provided, the description carries the full behavioral burden. It usefully discloses that no request body is retained, no payment occurs, and the result is non-binding, but it omits validation failure behavior, authentication or rate-limit requirements, and whether the request is stored or logged beyond the retention statement.

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 with the key framing ('Free public procurement preflight') front-loaded. The sentences are efficient and none is redundant, though the final privacy sentence could be considered secondary detail rather than essential invocation guidance.

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 validation tool with no output schema and an undocumented nested request object, the description is incomplete. It states the return type broadly and notes privacy constraints, but it does not explain what constitutes a valid request, what errors or validation failures look like, or what 'candidate bounded services' means in practice.

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?

The schema has 0% description coverage for a single required nested 'request' object, so the description must compensate. It adds that the request is 'buyer-authored' and 'authority-verification' and must match a 'public request schema,' but it does not describe the object's expected fields or structure, leaving the agent unable to construct a valid request from this definition 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 ('Validate') and resource ('procurement request'), plus the outcome ('return a non-binding scope-review handoff with candidate bounded services'). It does not explicitly differentiate from sibling tools such as procurement_catalog, but the procurement-specific wording makes the purpose clear.

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?

Describes the tool as a 'free public procurement preflight,' implying it should be used before a procurement request proceeds. However, it gives no explicit when-to-use rules, no exclusions, and no comparison to alternatives like procurement_catalog.

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