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

Despite readOnlyHint=true, the description adds substantial behavioral detail beyond annotations: pre-settlement versus post-settlement responses, server-side SHA-256 recomputation, matches=true/false, result, and verify_url. It also discloses responsible-use constraints, which is unusually complete for a read-only verification 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 front-loaded with the core verification behavior and then explains settlement-dependent returns. The legal disclaimer is relevant but slightly long; overall it remains purposeful and readable.

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 explain return values, and it does: sealed_at and kickoff_at before settlement, plus preimage, match status, result, and verify_url after settlement. An agent has enough information to call and interpret the tool.

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 single hash parameter is already documented as 64 hex characters or a unique prefix of at least 16. The description repeats the same format details rather than adding new parameter semantics, so baseline 3 is appropriate.

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 sealed BetsBeats pick from its SHA-256 commitment hash. It also clarifies accepted hash formats, which is more specific than the tool name alone and distinguishes it from sibling analysis 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?

It clearly describes the two usage contexts: before settlement it only confirms the hash exists, and after settlement it returns the revealed preimage and verification result. It does not explicitly compare against sibling tools or state when not to use it, but the context is strong enough for correct selection.

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