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

With no annotations, the description carries the full burden and does reasonably well: it discloses the state change (marks the order fulfilled), a side effect on another party (awards reputation credit), a credential requirement (party), cost, and source. It omits reversibility and behavior when the other party has not actually complied.

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?

Short and mostly front-loaded, with the operative effect stated before the credential/cost/source metadata. The first narrative sentence is a bit loose but not wasteful.

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 mutation tool with a side effect on a third party, no annotations, no output schema, and an undocumented parameter, the description should clarify what happens on failure or how compliance is verified. It covers credential, cost, and source, but leaves meaningful gaps.

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 0% for the single required parameter complianceId, and the description never explains what it is or how to obtain it — only the oblique phrase 'the order'. The schema does the bare minimum and the description does not compensate.

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+resource: confirming an order was fulfilled and awarding the other agent reputation credit. This distinguishes it from check_compliance (read-only) and dispute_compliance (challenge). The opening narrative sentence is quirky but the operative clause is precise.

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 an implicit precondition for use — 'the other agent has done what it required' — which tells the agent when this applies. However, it never names alternatives such as check_compliance, attest_compliance, or dispute_compliance, so the agent must infer the routing from the sibling list alone.

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