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

With no annotations, the description carries the transparency burden. It discloses that the tool verifies the fee mint on-chain, clears the obligation, and notes that unconfirmed obligations block future mints. This provides meaningful behavioral context beyond the basic action, though it does not cover edge cases like failure modes or idempotency.

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?

Three concise sentences, each adding value: action, verification effect, and consequence. Front-loaded with the verb 'Confirm.' No redundant or filler text; appropriately sized for the tool's complexity.

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?

The description covers the action, its effect, and its importance. With no output schema, it doesn't explain return values, but that is not mandatory. It could mention required permissions or failure behavior, but overall it gives sufficient context for an agent to understand when and why to invoke it.

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. The description does not add parameter-level detail beyond what the schema already provides; it reinforces the meaning of obligation_id as returned by mint_loyalty_tokens or earn_points, but that is already in the schema. No additional semantic enrichment is present.

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 specifies the action: confirming that a protocol fee transaction was broadcast on Base. It distinguishes itself from mint/earn tools by focusing on the verification and obligation-clearing side, and adds context that unconfirmed obligations block future mints, making the purpose unambiguous.

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 when to use this tool: after a previous mint/earn, to verify the fee mint and clear the obligation. It also explains the consequence of not using it (future mints blocked), which guides usage. However, it does not explicitly name alternative tools or state when not to use it, so it falls short of a 5.

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