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

With no annotations, the description carries the full burden and discloses meaningful behavior: no authentication required, the check is authoritative/on-chain, and any supplied content is re-hashed server-side and never stored or logged. It does not describe error cases, result shape, or rate limits, but the privacy and auth disclosures are substantive.

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?

Three compact sentences, front-loaded with purpose followed by auth and privacy details. Every sentence adds useful information with no repetition or filler.

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 three-parameter verification tool with no annotations and no output schema, the description covers purpose, auth, and content-privacy handling well. But it never explains what a verification result looks like or how failure is reported, leaving an important gap for an agent deciding what to expect from the call.

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%, so the description must compensate, and it does: tx_hash is presented as the primary lookup key, content_hash as a comparison target, and content as optional input that is locally re-hashed. It still omits format requirements and what happens if all optional parameters are omitted.

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?

States a specific verb and resource: an authoritative on-chain check keyed by tx_hash and/or content_hash. It is clear what the tool does, but it does not explicitly differentiate itself from siblings like verify_decision_chain or check_anchor_status.

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 explains how to invoke it (by tx_hash and/or content_hash, optionally with content for local re-hashing) and notes that no auth is needed. However, it gives no explicit when-not-to-use guidance or named alternatives among the sibling verification tools.

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