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

No annotations are provided, so the description carries the full burden, and it does: it states no transaction is needed, enumerates exactly what is returned (leaves, live-recomputed root, Solana-stamped root, match flag, anchoring transaction, signing treasury wallet), and explains where the real trust guarantee lives (on-chain memo format, signed by a fixed treasury wallet, landed after the day ended). This is unusually complete behavioral disclosure.

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?

Front-loaded with the core purpose and scoping constraint before the alternative and the verification recipe, and every sentence carries information. The final sentence is dense and long, packing the memo format, signer, and timing constraint into one clause chain, but it is not padded.

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?

There is no output schema, so the description must (and does) enumerate the return payload, and it additionally supplies the independent verification procedure an agent would otherwise lack. For a one-parameter verification tool this is 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?

Schema coverage is 100% and the schema already documents the period format and omission behavior, so the baseline is 3. The description adds genuine meaning to the omission ('audit the most recent stamped day, which makes it suitable for continuous monitoring'), going beyond the schema's terse 'Omit for the latest stamped day.'

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 states a specific verb and resource ('Verify a whole day of the claim ledger against its stamped Merkle root') and immediately distinguishes itself from the sibling: 'verify_claim answers whether one payout is in the ledger; this answers whether the ledger itself is intact.' An agent can pick correctly without opening either schema.

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?

Explicit when-to-use is given ('Omit the period to audit the most recent stamped day'), including a rationale ('suitable for continuous monitoring'), and the alternative verify_claim is named with the condition that selects it. Nothing is left to inference.

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