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

Annotations already declare readOnly, idempotent, and non-destructive behavior. The description adds useful context on top: deterministic analysis, the specific classes of findings produced, and the $0.002 per-call cost. No contradiction with annotations exists, though exact response format is not disclosed.

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?

Three sentences front-load the core function, then add a clear use case, exclusions, and cost. Every sentence earns its place, and there is no repetition of schema or annotation details.

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 gives solid high-level context: what it analyzes, when to use it, what to avoid, and cost. With no output schema and an opaque `steps` array, however, an agent still lacks enough detail about input element structure and the exact return contract to invoke it confidently.

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?

The sole parameter `steps` has no element schema and 0% schema description coverage, but the description supplies domain meaning by framing it as the steps of a partially completed multi-step transaction and referencing irreversible successful steps and compensating actions. However, it does not specify the exact object shape, status fields, or compensation linkage required inside each step.

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 first sentence states a precise behavior: deterministic coverage analysis for multi-step agent transactions, specifically identifying irreversible successful steps lacking compensating actions and unsafe compensation order. This goes beyond the title and clearly separates it from broader sibling tools like execution_safety_preflight or outcome_assurance_verification.

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 explicitly says to use the tool when deciding whether a partially completed multi-step transaction can be safely unwound, and instructs not to use it for unrelated general knowledge or unsupported legal/identity/sanctions/fraud/contractual/regulatory adjudication. It stops short of naming a specific sibling alternative, so it does not reach the top of the scale.

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