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

Annotations already establish readOnly, openWorld, and idempotent behavior; the description adds useful context: paid resource with exact x402 price, deterministic output, and a 'result unverifiable' caveat. No contradiction with annotations.

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 are front-loaded with the core behavior, followed by domain restrictions and pricing with minimal waste. The 'trust identity permission / result unverifiable' phrasing is oddly compressed, preventing a 5.

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?

Purpose, exclusions, and cost are covered, and annotations cover the safety profile. But with no output schema, the return format of 'deterministic execution order or concrete blockers' is underspecified, and optional constraint parameters are not explained. This is adequate for a first call but leaves meaningful gaps.

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, but it only references 'workflow dependencies and execution constraints' without mapping them to nodes, edges, max_total_cost, or max_total_latency_ms. The generic framing leaves the agent to infer parameter roles from property names alone.

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 specific action ('Validates caller-supplied workflow dependencies and execution constraints') and a clear result ('deterministic execution order or concrete blockers'). It does not explicitly differentiate itself from sibling trust_identity_permission control planes or workflow_dependency_validator, 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?

It names an intended use ('trust identity permission / result unverifiable') and an explicit exclusion list ('Do not use for legal, identity, sanctions, fraud, contractual, or regulatory adjudication'). It provides when and when-not but does not name specific alternative tools, so not a 5.

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