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

Beyond the annotations, the description discloses that the result is deterministic, that the tool returns either an order or blockers, and that it is a paid resource with a concrete per-call price. None of this contradicts readOnlyHint=false, openWorldHint=true, idempotentHint=true, or destructiveHint=false.

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 short sentences cover purpose, intended domain, prohibited domains, and pricing with little waste. The only slightly cryptic phrase is 'result unverifiable,' but it does not undermine overall conciseness.

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 inputs, output shape, and cost, which is useful given there is no output schema. However, it does not define what 'execution constraints' means beyond the schema names, clarify the 'result unverifiable' context, or describe what a concrete blocker looks like, leaving some behavior for the agent to infer.

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?

With schema description coverage at 0%, the description was expected to compensate, but it only maps broadly to nodes/edges as 'workflow dependencies' and max_total_cost/max_total_latency_ms as 'execution constraints.' It does not explain node fields like enabled/cost/latency_ms, edge direction semantics, or how constraints are applied, leaving most parameter meaning to be inferred from names.

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 names a specific verb ('Validates'), a concrete resource ('caller-supplied workflow dependencies and execution constraints'), and a defined output ('deterministic execution order or concrete blockers'). It is not a tautology, but it does not explicitly distinguish itself from sibling tools like workflow_dependency_validator or the other reliability_quality_orchestration_* variants, 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 description states an intended domain ('reliability quality / result unverifiable') and gives explicit when-not-to-use exclusions for legal, identity, sanctions, fraud, contractual, or regulatory adjudication. It does not name alternative tools, so the guidance is clear context without a direct routing recommendation.

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