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

With no annotations provided, the description carries the full burden. It discloses the paid execution model ($5.00 USDC via x402 on Base), which is a critical behavioral side effect, and it promises deterministic outcomes with hash-bound proof. It does not discuss failure modes, refunds, or what happens if evidence is invalid, but the paid-execution warning and deterministic-state contract go well beyond what the schema could convey.

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 compact: two sentences, with the core return contract front-loaded and the payment warning placed second. It wastes no words and uses a scannable CAPS list for return states. A slight deduction because the payment detail could arguably be more prominent, but overall it is tight and purposeful.

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 tool has 7 parameters, nested objects, and an output schema; the description covers the core purpose, return categories, and the payment side effect. It does not describe the shape of the output beyond the three labels, but the presence of an output schema reduces that burden. What remains missing is a brief when-to-use sentence, which would make this fully complete.

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 bar is lower. The description itself adds no per-parameter meaning beyond 'missing requirements, normalized packet, and hash-bound proof' in the return value. The input schema already explains subject, evidence, completion_claim, and the optional fields, so the description need not repeat them; 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 ('reconciles'), a resource (operational handoffs), and names the three deterministic return states (COMPLETE, INCOMPLETE, NEEDS_REVIEW). It also conveys the evidence-based, hash-bound nature of the result, which clearly distinguishes it from a generic status or approval tool.

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 this tool is relevant—when an operational handoff needs deterministic reconciliation evidenced by receipts/logs/hashes—but it offers no explicit when-not-to-use guidance or alternative tools. Since there are no sibling tools listed, the absence of alternatives is less damaging, but explicit usage context such as 'use for post-handoff verification' is still missing.

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