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

The readOnlyHint and destructiveHint annotations already establish this as a safe read operation, lowering the disclosure burden. The description adds useful content context by saying the result includes signed receipts and receipt-chain re-verification, but it does not describe pagination, authorization expectations, or the shape of the returned verification result.

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 definition is a single front-loaded sentence with no filler. The "+" construction and compound phrase "receipt-chain re-verification result" are slightly dense, but the sentence remains 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?

For a zero-parameter, read-only list tool with no output schema, the description is reasonably complete: it identifies the operator scope and signals that re-verification results are included. More detail on return structure or result semantics would help, but the essential purpose is covered.

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 tool has zero input parameters, so there is no parameter semantics burden on the description. The baseline score for a zero-parameter tool is appropriate here.

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 uses a specific verb, "List," and a specific resource, "this operator's signed verdict receipts + receipt-chain re-verification result." It clearly states scope via "this operator's," but it does not explicitly distinguish itself from sibling tools such as last_verified_success or verify_now.

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 no explicit guidance on when to use this tool, when not to use it, or which sibling tools are alternatives. The listing purpose is implied, but an agent must infer the appropriate context from the name and siblings.

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