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

No annotations are provided, so description must fully disclose behavior. It mentions 'deterministic' and 'without charging', but lacks details on side effects, idempotency, authentication needs, or rate limits.

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?

Single sentence is concise and front-loaded with key action, but could be slightly longer to include critical details without being wasteful.

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 tool has 4 parameters, no output schema, and no annotations, the description is insufficient. It lacks parameter explanations, return value format, and behavioral context needed for reliable use.

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% and description does not explain any of the 4 parameters (product_url, target_marketplace, product_description, current_payment_flow), providing no added meaning beyond bare field names.

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?

Description clearly states it creates a deterministic quote and recommended buying path without charging, distinguishing it from sibling tools like hilt_get_pricing or hilt_get_offer that likely only retrieve data.

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?

Description states the action but provides no guidance on when to use this tool versus alternatives, such as when to create a quote vs. get pricing or offers.

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