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

Annotations cover the safety/idempotency profile (idempotentHint=true, destructiveHint=false, openWorldHint=false), and the description adds real behavioral context beyond them: possible outcomes (go/no-go/unsupported), produced artifacts (normalized source, warnings, evidence), and concrete limits (local evidence only, 3 verification qubits, 65536 source bytes). It does not mention that the call carries a price, which is a notable omission given max_total_price is required, but nothing contradicts 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 Problem/Input/Result/Limits framing is compact, front-loaded, and wastes almost no words; every clause carries information. It is slightly telegraphic for a tool with a 4-field required envelope, but density here is a virtue rather than padding.

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?

An output schema exists, so verdict/warning detail need not be re-explained, and the description covers purpose and limits adequately. What is missing is the calling contract: the required request envelope, idempotency key, and pricing field are undocumented in both schema and description, which leaves an agent under-informed for a paid, job-submitting tool with a nested object parameter.

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% across 4 required parameters, so the burden falls on the description, and it only partly delivers: 'JSON with source' gestures at the payload, but schema_version, idempotency_key, and max_total_price are never explained, and the nested 'request' envelope is opaque. A user cannot tell from the text where 'source' actually lives in the schema.

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 names specific verbs and resource: 'Parse, normalize, and assess OpenQASM 3 before downstream execution.' That is far more than a restatement of the title and tells the agent this is a validation/preflight step, not an executor. It does not, however, set itself apart from the very similar sibling quantum_openqasm3_repair_v1 / repair_openqasm3.

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?

'before downstream execution' implies when this belongs in a workflow, but there is no explicit when-not guidance and no routing to alternatives such as repair_openqasm3 or check_quantum_circuit in the sibling list. Usage is inferable rather than stated.

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