ScoutWyze FIPS: is this version FIPS 140-3 validated?

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

With no annotations, the description carries the full burden and does so: fail-closed behavior (UNVERIFIED rather than ACTIVE when data is stale), the rate limit and prepaid-credit model, the exact 402/x402 USDC-on-Base challenge and X-PAYMENT retry contract, the statement that the server itself cannot pay, and that 404s are free. It also discloses what the response includes (certificates, sunset dates, PQC algorithms, receipt links) and a legal-advice disclaimer.

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?

Front-loads the core purpose and return values, then layers on the payment and failure semantics. Dense but nearly every clause earns its place; the x402 paragraph is long but is genuinely load-bearing for an agent that hits a 402.

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?

No output schema exists, yet the description enumerates the possible status values and the fields returned, plus the failure modes (402, 404) and their remedies. Nothing an agent needs in order to call this correctly or interpret a non-200 is missing.

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% and both parameters carry examples, so the schema does the heavy lifting. The description adds only the notion of a single product-version pair and does not elaborate on alias matching or version-format tolerance beyond what the schema already shows.

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 and resource — 'Returns the FIPS 140-3 status of one product version from NIST CMVP data' — and enumerates the exact return statuses, so the agent knows what comes back. The 'one product version' scope implicitly separates it from fips_batch and fips_list_products, which operate over sets.

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?

Gives clear operational context: free lookups per day, API-key/credit path, 402 x402 payment retry flow, and that unmapped products return 404 with the known list (pointing toward fips_list_products). It never explicitly names fips_batch or fips_expiring as the alternative for multi-product or sunset-focused queries, so routing between siblings is left to inference.

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