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

Annotations already declare readOnly, idempotent, openWorld, and non-destructive. The description adds behavioral value by stating it returns a deterministic execution order or concrete blockers, and it discloses the x402 price per call. No contradiction with annotations; the additional cost and return behavior go beyond what annotations provide.

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 three sentences, each earning its place: one for core behavior, one for scope exclusions, one for cost. The main action is front-loaded. The 'cannot select' phrase is awkward but not redundant or bloated.

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 covers core behavior, exclusions, and cost, making it minimally viable. However, with 4 parametersashing, no output schema, and 0% schema description coverage, it lacks output format details, parameter examples, and blocker/error representation. The schema names are moderately self-explanatory, but an agent would still need to infer too much to call this reliably in all edge cases.

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%, so the description must compensate. It only gives high-level hints like 'workflow dependencies' (likely edges) and 'execution constraints' (likely cost/latency), but never explains the node schema, required vs optional constraints, or property semantics. This is insufficient for correctly constructing a call with four parameters.

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 ('Validates') and resource ('caller-supplied workflow dependencies and execution constraints'), plus a concrete return type ('deterministic execution order or concrete blockers'). The phrase 'Intended for trust identity permission / cannot select' is confusing and slightly muddies the scope, but the core purpose is clear and distinguishes this from adjudication tools.

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 explicitly provides a when-not-to-use list: 'Do not use for legal, identity, sanctions, fraud, contractual, or regulatory adjudication.' It also implies intended use for trust identity permission. However, it does not explicitly name sibling alternatives or conditions for preferring one control plane over another.

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