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

The annotations already mark the tool as read-only, non-destructive, and closed-world. The description adds substantial behavioral context beyond those annotations, including that it reads only call material, makes no external writes or network requests, costs USDC via x402, requires a wallet proof header, and returns an Ed25519 signed receipt.

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 and information-dense, with all major operational details stated early. It is longer than average, but most sentences carry relevant context for a paid, signed readiness check; the contract and human-page URLs are slightly extra but still useful.

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?

This is a complex paid tool with nested inputs and no output schema, so the description must carry the return-value burden. It explains the report structure, verdict values, receipt signing, safety behavior, payment model, and authentication requirement, which is complete enough for correct invocation.

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 100%, so the schema already documents the parameters in detail. The description reinforces the five rule areas and says rules can be supplied as fields or as words, but it does not add parameter-level syntax, constraints, or meaning beyond what the schema provides.

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 action: submit an agent rule set for an adoption readiness check and receive a signed report. It clearly distinguishes the tool from the sibling spending-policy check, so an agent can identify the resource and scope without opening the 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?

It gives a clear context for use: an operator planning to hand a rule set to an agent and wanting readiness by area. It also names the alternative for spending policy controls, though it does not give explicit when-not conditions beyond that.

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