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

There are no annotations, so the description must carry the full burden of behavioral disclosure. It mentions 'FREE' and lists the verification checks, but it does not state whether the operation is read-only, what the success/failure response looks like, whether it performs any writes, or if authentication is required.

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 exceptionally concise: two short sentences with no filler. 'FREE.' adds a practical cost signal, and the main sentence front-loads the tool's core purpose and verification scope. Every word earns its place.

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 tool with two required nested-object parameters, no output schema, and no annotations, this description leaves significant gaps. An agent can tell what the tool does, but not how to construct valid inputs, what the response format is, or how verification results are reported.

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 both parameters are opaque nested objects. The description names verification-related concepts like signature, payload hash, ledger anchor, and issuer key, but it does not explain how these map to the 'receipt' and 'proof' parameters or what structure those objects should have.

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 states a specific verb and resource: 'Verify a KHOTEM Ed25519 receipt'. It further clarifies what verification covers—signature, payload hash, ledger anchor, issuer key—which goes well beyond the tool name and distinguishes it from receipt creation or attestation tools.

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 the tool should be used when a KHOTEM receipt and proof need verification, but it does not explicitly state when to use it versus siblings like khotem_receipt or khotem_seal. No exclusions, prerequisites, or alternative tool references are provided.

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