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

With no annotations provided, the description fully carries the behavioral disclosure burden. It discloses that the tool is deterministic/rules-engine, costs $0.25 USDC on Base, returns an x402 URL rather than final data, and requires a GET → payment-signature → delivery flow. It also clarifies the call itself is free.

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?

Each sentence earns its place: scope, deterministic behavior, cost, URL/payment flow, and the free-to-call distinction. It is front-loaded with the core purpose and contains no redundant prose.

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?

Despite having no output schema, the description explains the return mechanism (x402 URL, 402 → payment-signature → delivery), the cost, and the substance of what will be delivered (CE hours, classroom/ethics, renewal fees). Both required parameters are well documented in the schema, and no critical invocation information 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?

The schema already fully describes both parameter (license_line and years_licensed) with constraints and examples. The description adds that outputs vary 'by license line and years licensed' but does not add new format or constraint details, so the 100% schema-coverage baseline of 3 is appropriate.

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 the exact domain and action: a Texas insurance license CE & renewal check using TDI. It further specifies the substantive outputs (CE hours, classroom/ethics requirements, renewal fees) and inputs (license line, years licensed), which distinguishes it from sibling tools like the Texas real estate CE check.

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 clear context: this is for Texas insurance license compliance and renewal checks using deterministic TDI rules. It does not explicitly name sibling tools or state exclusions, so an agent has to infer when alternatives like check_broker_authority or check_tx_realestate_CE are better fits.

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