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

No annotations are provided, so the description carries full burden. It mentions 'post-quantum receipt' implying cryptographic behavior, but does not disclose whether the operation is destructive, what permissions are needed, or any side effects. The behavior is minimally transparent.

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 sentence, concise with no superfluous words. However, it is too brief for a tool with six parameters, leaving out critical parameter semantics.

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 presence of an output schema, return values need not be explained. However, with six parameters and zero schema coverage, the description fails to provide enough context for correct usage. Sibling differentiation is implicit but not elaborated.

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 the description adds no meaning to any of the six parameters. While agent_id, operation, and target are self-explanatory, parameters like inputs, policy, and decision have defaults but are not explained in the description.

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 the tool mints a post-quantum receipt for any consequential agent action. The verb 'mint' and resource 'post-quantum receipt for an arbitrary consequential agent action' are specific. Among siblings, it stands out as the general-purpose receipt minting tool vs. mint_receipt_for_record_change which is specific to record changes, and verify_receipt which is for verification.

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 implies usage for arbitrary consequential agent actions, but it does not explicitly state when to choose this over sibling tools like mint_receipt_for_record_change or verify_receipt. No contraindications or alternative guidance is provided.

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