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

No annotations are provided, so the description must carry the full burden. It discloses the technical reference (Polygon ZK attestation + XRPL report anchoring) but does not state whether it is read-only, what the output format is, or any side effects. Lack of detail about return behavior is a gap for a status tool.

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 core purpose. It is efficient but could include a bit more context (e.g., output type) without becoming verbose.

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?

With no output schema and no annotations, the description is insufficiently complete. It doesn't explain what the status means, what values are reported, or how the anchoring mechanism relates to usage. Given the tool's simplicity, a short output description would significantly improve completeness.

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 the schema is trivially covered. Per the rubric, 0 params gets a baseline of 4. The description does not need to explain parameters that don't exist.

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 tool's subject: on-chain anchor status specific to Polygon ZK attestation and XRPL report anchoring. While the verb is implicit (get/check), the phrasing conveys a status-checking action. It distinguishes from sibling proof/verification tools by focusing on anchor status rather than proofs.

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 explicit guidance on when to use this tool versus alternatives. The description implies it's for checking anchoring status, but does not mention conditions, prerequisites, or contrast with sibling tools such as verify_commitment or audit_proof.

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