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

Annotations already cover idempotency, destructiveness, and open-world behavior; the description adds the concrete $0.002 per-call price and the promise of deterministic output. It does not explain side effects, required auth, or how blockers are represented, but it does not contradict the 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 with the function first, then exclusions, then pricing; no boilerplate or redundant fluff. The phrase 'cannot select' is cryptic, but it does not inflate the length. The structure is easy to scan.

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?

There is no output schema, so the return description should be more precise than 'deterministic execution order or concrete blockers'. It also omits error behavior for invalid graphs or cycles and does not explain how the optional constraint parameters relate to the blockers. For a graph-based orchestration tool with four undocumented parameters, this is incomplete.

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 0% schema-description coverage, the description must carry parameter meaning. It broadly labels 'workflow dependencies' (nodes/edges) and 'execution constraints' (max_total_cost/max_total_latency_ms), but never explains individual fields, units, optionality, or how enabled/cost/latency affect ordering. Most semantic weight remains on the field 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?

Clearly identifies the action ('Validates') and resource ('workflow dependencies and execution constraints') and says what it returns ('deterministic execution order or concrete blockers'). The 'Intended for execution safety / cannot select' line plus explicit exclusions separates it from legal/identity/selection siblings, but it does not differentiate this hashed orchestration variant from the other execution_safety_orchestration_* 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?

Gives positive scope ('execution safety / cannot select') and explicit negative scope (legal, identity, sanctions, fraud, contractual, regulatory adjudication), so an agent knows when not to invoke it. It does not name a fallback sibling tool for those excluded domains, so the guidance stops short of a full decision tree. The paid-resource note adds a practical cost consideration.

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