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

The description discloses the credit cost on success and the release on failure, which are behavioral traits not captured in the annotations. This provides useful transparency about side effects and resource consumption.

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?

The description is concise, using only two sentences without unnecessary verbiage. However, the structure is somewhat disjointed, mixing payment details with the core function, but overall it is efficient.

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?

The description is incomplete for effective agent use. It lacks details on the validation logic, expected input format, possible outputs (no output schema), and error conditions. Critical context 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?

Neither the schema nor the description explains the meaning or expected format of 'raw_intake' or 'idempotency_key'. The description fails to compensate for the complete lack of parameter documentation, leaving the agent to guess.

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?

The description 'Paid bounded intake validation' is vague and does not clearly state what the tool actually does or what 'intake' refers to. It focuses more on the payment model than on the validation functionality.

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 provides no guidance on when to use this tool versus the listed sibling tools. It does not mention any specific use case or selection criteria, leaving the agent without direction for appropriate invocation.

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