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

With no annotations, the description carries the full burden, and it does disclose meaningful behavior: neutral third-party execution, a RELEASE/REFUND verdict, that OMENZ never holds funds and the payer must act, a signed attestation, and that the playzone differs from the paid production endpoint ($0.005 via x402). It omits, however, whether the call mutates state, whether it is idempotent, and what happens on test failure or timeout.

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?

Front-loaded with the core action and outcome, then supporting details. Some bytes go to branding and the AYNE playzone preamble, but the price and endpoint note is genuinely useful for invocation context, so the density is acceptable.

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 explains return concepts well (PASS/FAIL, escrow_verdict, attestation) despite no output schema. But for a two-parameter, no-annotation, state-changing escrow tool, it leaves the parameter contract, auth expectations, and failure behavior unaddressed.

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 0% and 'delivered' is fully untyped with no constraint, but the description never says what either parameter should contain, what form a token takes, or what artifact 'delivered' refers to. Two required, entirely undocumented parameters is a serious gap the description does not compensate for.

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?

States a specific action and outcome chain: a neutral party runs the contract's tests against what was delivered and emits PASS/FAIL, an escrow_verdict, and a signed attestation. That is far more than a restatement of 'contract_accept'. It does not explicitly contrast itself with the sibling contract_build, so it stops short of a 5.

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 phrase 'runs the contract's tests on what was delivered' implies the tool is used after delivery exists, which gives usable context. But there is no explicit when-to-use/when-not, no statement that contract_build must precede it, and no guidance on how it relates to reputation or finance_refund_request siblings.

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