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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true, so the description's additional statement that it returns a deterministic order or blockers and the $0.002 cost adds value without contradiction. However, it does not describe failure modes, authentication, or other behavioral details, so it only marginally exceeds 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 brief and front-loaded with the core purpose. It efficiently includes price and exclusions in a few sentences, though the phrase 'Intended for execution safety / quality unknown' is vague and could be clearer. No filler words, but the vague phrase lowers it from 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?

With 4 parameters, no output schema, and many closely-related siblings, the description is incomplete. It does not explain node/edge semantics, constraint behavior, or how to interpret the returned order/blocks, nor does it position itself relative to other orchestration tools. The cost note is helpful but cannot compensate for these 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. It only vaguely mentions 'workflow dependencies and execution constraints,' hinting at nodes/edges and max_total_cost/latency, but does not explain the meaning of individual parameters like cost, latency, or enabled. This is insufficient for a 0% coverage situation, earning a low score.

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 clearly states the tool validates caller-supplied workflow dependencies and execution constraints and returns a deterministic execution order or concrete blockers, giving a specific verb and resource. However, it does not differentiate from the many other execution_safety_orchestration_* siblings, so it earns a 4 rather than 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 gives explicit exclusions (do not use for legal, identity, sanctions, fraud, contractual, or regulatory adjudication) and notes the paid nature, but it does not state when this tool should be used over alternatives or name any sibling tools. The intent is implied but not explicit, leaving the agent without clear selection guidance.

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