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

Annotations already provide readOnlyHint=false, destructiveHint=false, idempotentHint=true, and openWorldHint=true. The description adds that it returns a deterministic execution order or concrete blockers, and states the x402 price. It does not disclose any side effects despite readOnlyHint=false, nor does it elaborate on the 'trust unknown' phrase. The added cost and return behavior are useful, but the description doesn't go beyond that, so it's adequate but not rich.

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 efficient and front-loaded: the primary purpose is stated in the first sentence, followed by usage exclusions and pricing. There is no fluff. It could be slightly more structured (e.g., separating usage notes), but it is appropriately concise for the information it conveys.

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 tool is a graph-based orchestrator with constraints, but the description provides no details on input format, output structure (beyond 'execution order or blockers'), error conditions, or the meaning of 'concrete blockers'. It also omits the maxItems/minItems constraints. Given the complexity and lack of an output schema, the description is incomplete for an agent to call it correctly without additional inference.

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?

The schema has 0% description coverage, and the description does not explain any of the four parameters (nodes, edges, max_total_cost, max_total_latency_ms). It only vaguely refers to 'caller-supplied workflow dependencies and execution constraints', which does not help an agent understand parameter semantics, types, or constraints. With no schema descriptions, the description fails to compensate, leaving agents to infer from 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 description clearly states the tool validates workflow dependencies and execution constraints, returning a deterministic execution order or concrete blockers. It names a specific verb and resource, and adds exclusions (not for legal, identity, etc.) that help scope it. However, it does not explicitly differentiate from the many execution_safety_* sibling tools, so it lacks direct sibling contrast.

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 context: 'Intended for execution safety / trust unknown' and lists domains where it should NOT be used (legal, identity, sanctions, fraud, contractual, regulatory). This provides some usage boundaries but no explicit alternatives or when-to-use guidance relative to sibling tools. It also mentions it's a paid resource, which may affect decision-making, but the 'when not to use' is the strongest part.

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