create_receipt

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

The description mentions 'privacy-first' but gives no concrete behavioral details such as data handling, side effects, or security requirements. No annotations exist to supplement this.

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 a single concise sentence that front-loads the action and object. It is appropriately short, though it sacrifices detail for brevity.

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 fails to explain how the parameters fit the receipt creation process, what the receipt contains, or what the output looks like. It is incomplete given the tool's complexity.

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 lists five parameters but none have descriptions. The tool description does not explain any of them, leaving their purpose and relationships completely unspecified.

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 clearly states the action (create) and the resource (a signed receipt) for an MCP tool call. It is specific enough to understand the core purpose, though it could elaborate on what the receipt includes.

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?

No usage context is provided. It does not mention when to use this tool versus the sibling 'verify_receipt', nor any conditions or alternatives.

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