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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds value beyond those by stating deterministic output, concrete blockers, and that this is a paid resource at a specific x402 price. There is no contradiction with 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?

The description is three sentences with no filler. The first sentence front-loads the action and output, the second defines scope and exclusions, and the third adds cost information. Every sentence earns its place.

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 has a complex graph-shaped input, no output schema, and zero parameter descriptions, yet the description provides only high-level purpose and constraints. It conveys what the tool returns and when it applies, but an agent would still be uncertain about how to construct valid nodes/edges and interpret cost/latency constraints. This is adequate but has clear 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 carries the burden of explaining parameters, but it never mentions nodes, edges, max_total_cost, or max_total_latency_ms directly. The phrases 'workflow dependencies' and 'execution constraints' only vaguely gesture at the schema, leaving the agent without units, semantics, or guidance on how enabled/cost/latency fields interact.

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 states a clear verb and resource: it 'validates caller-supplied workflow dependencies and execution constraints' and returns 'a deterministic execution order or concrete blockers.' It also narrows the intended domain to 'trust identity permission / availability failure.' However, it does not distinguish this tool from the many sibling trust_identity_permission_control_plane_* variants.

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 an explicit intended-use context ('Intended for trust identity permission / availability failure') and an explicit when-not list ('Do not use for legal, identity, sanctions, fraud, contractual, or regulatory adjudication'). It does not name alternative sibling tools to use instead, so the guidance is clear but not complete.

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