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

Annotations already declare this as read-only, idempotent, and non-destructive. The description adds useful context about the content returned, including third-party receipt types, but no additional behavioral details such as response shape or independent verification mechanics.

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 that front-loads the main resource and then lists the key supporting artifacts. It is compact and contains no filler, though the technical detail is somewhat dense.

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 parameterless read-only tool, the description sufficiently conveys what will be returned and the verification purpose. It does not specify exact output structure, but with no output schema and strong annotations, the definition is largely complete.

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 parameters, and schema coverage is effectively complete, so there are no parameter semantics for the description to clarify. This matches the baseline for a parameterless tool.

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 identifies the resource: the latest public ledger fingerprint, its RFC 3161 and OpenTimestamps receipts, and verification instructions. It is specific enough to be distinguished from siblings like get_public_record, though it does not explicitly name sibling distinctions.

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 phrase 'how to verify the record independently' implies the tool is for verification-related lookups, giving some usage context. However, it does not explicitly state when to prefer this tool over siblings such as get_current_state or get_public_record.

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