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

Annotations already indicate readOnlyHint=false, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is partially covered. The description adds that it returns a bounded go/no-go/unsupported decision with evidence, which is useful context. However, it doesn't explain cost implications despite required max_total_price and payment_rail parameters, nor does it describe what 'sending downstream' entails.

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 a single efficient sentence that front-loads the purpose and outcome. It is concise with no wasted words, though it could be slightly more informative.

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 schema with nested objects, required parameters, and an output schema. The description covers the high-level purpose but omits critical details such as parameter semantics, cost handling, and how the decision is determined. Given the complexity, it is only minimally complete.

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%, but the description does not compensate by explaining any parameters. The parameters (idempotency_key, max_total_price, request.circuit, payment_rail) are entirely undocumented in both schema and description. Baseline 3 is assigned because with low coverage, the description should do more but does not. No credit for parameters.

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?

Tautological: description restates name/title.

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 implies usage ('safe to send downstream') but doesn't explicitly state when to use this tool versus alternatives like quantum_openqasm3_preflight_v1 or quantum_provider_readiness_check_v1. No exclusions or prerequisites are provided.

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