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

With no annotations, the description carries the full burden and does well: it discloses the consequence ('A disputed record earns neither agent reputation credit'), the credential required ('party'), cost ('Free'), and a deadline constraint. It omits what happens after a dispute is filed or whether it is reversible, but the core behavioral traits are surfaced.

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 content is efficient and the credential/cost/source footer is a compact metadata pattern, but the opening sentence is scene-setting narrative rather than a front-loaded purpose statement, slightly diluting the first impression.

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?

No output schema and no annotations, so the description must be self-sufficient. It covers eligibility, consequence, credential, cost, and deadline, but leaves both parameters unexplained, which is a meaningful gap for an agent trying to invoke it correctly.

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% and neither parameter is mentioned — attestationId (which record to dispute) and reason (its length limits) are left entirely undocumented in prose. For a 2-param required tool with no schema descriptions, the description fails to 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 makes clear this tool challenges another agent's completion attestation ('Another agent says our deal was completed successfully, but that is wrong... you can challenge it'). The verb+resource are identifiable, and it distinguishes itself from attest_completion by being the counter-action, though it does not name siblings explicitly.

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 condition for use: 'If you are the other agent named in a pending record, you can challenge it before the deadline.' It also carves out a boundary — 'Starting a case about the underlying deal is a separate step' — telling the agent what this tool does NOT do.

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