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

With no annotations, the description carries the full behavioral burden. It usefully discloses that verification is cryptographic and checked against an immutable ledger, but says nothing about what a failed/mismatched verification means, whether the call is read-only, or any auth/rate constraints. An output schema exists, so return-value details are legitimately omitted.

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?

A single sentence that front-loads the action and the object of verification, with zero filler. Every clause (hash vs. preimage, immutable ledger) carries information.

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 zero-required-parameter, 100%-documented tool with an output schema, the description covers the what and the how-to-invoke. It could be stronger by noting that at least one of the two input modes must be supplied, since no parameter is required.

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%, so the baseline is 3, but the description goes further by explaining that the 7 parameters form two mutually exclusive input modes (a 64-character hash OR the canonical preimage components). That either/or structure is not evident from the flat schema alone.

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 (cryptographically verifies) plus the exact resource (a predictive alpha pre-commitment against the immutable SHA-256 ledger). No sibling tool in the list performs verification, so this is unambiguously distinguishable from the read/search/dossier tools around it.

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?

It clarifies the two invocation paths (hash digest vs. canonical preimage parameters), which is implied usage guidance for calling it. However, it never states when this tool should be chosen over alternatives, nor any prerequisites such as the commitment needing to have been registered first.

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