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

No annotations are provided, so the description carries the full burden. It discloses that Insight collects the on-chain fill, signs a receipt, and returns one of four verdicts (FAITHFUL / DEVIATED / NOT_EXECUTED / UNDETERMINED), which is useful behavioral context. It does not explain signing requirements, failure modes, rate limits, or how the receipt is secured, leaving gaps for a signing operation.

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 four sentences and front-loads the core action and required inputs before describing the verdict and scope limitation. It is efficient, though the long list of fields in the first sentence is somewhat dense.

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 an 18-parameter signing tool with no output schema, the description covers purpose, required inputs, verdict output, scope boundaries, and related tools. It lacks details on signing requirements or error handling, but is otherwise complete enough for an agent to invoke 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 100% and all 18 parameters are documented in the schema. The description groups the required pre-trade fields and settlement txHash, adding grouping context but no syntax or format details beyond the schema. Baseline 3 is appropriate when the schema does the heavy lifting.

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 and resource: it issues signed execution-price evidence comparing an observed fill to the oracle-assessed quote and signed slippage band, and returns a verdict. It distinguishes itself from siblings by explaining it pairs with pre_trade_safety_check and oracle_watch and produces a fidelity receipt rather than a safety or price query.

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 gives a clear context: provide the pre-trade fields plus settlement txHash after execution, and it names pre_trade_safety_check and oracle_watch as companion tools. It states what it does not do (principal authorization or overall transaction safety), which helps avoid misuse, though it doesn't explicitly state when not to call it versus verify_execution_pair.

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