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

No annotations provided, so the description carries full burden. It discloses synchronous behavior, qubit limit, cost ($0.05 USDC), seeded determinism, and simulation methods. Missing details on error handling or rate limits, but sufficient for basic awareness.

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 dense paragraph of about 50 words. It front-loads purpose and packs useful details. Could benefit from slight structuring (e.g., bullet points) but remains efficient.

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?

No output schema exists, yet the description does not explicitly state what the tool returns (e.g., statevector, expectation values). It hints at outputs ('shots, expectation values') but does not clarify structure or examples. Also missing seed parameter usage, leaving some ambiguity.

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 input schema has 100% coverage but vague descriptions ('The structured problem for this operation'). The description adds concrete meaning: operation='simulate', spec includes qubits, gates, shots, method. This greatly enhances parameter understanding beyond 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?

Description clearly states the tool simulates quantum circuits, lists supported methods (statevector, density-matrix, etc.), and specifies constraints (≤24 qubits, sync tier). This strongly identifies the tool's action and resource, distinguishing it from siblings like chemistry or numerical.

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 provides explicit usage instructions: 'Pass operation='simulate', spec={qubits, gates:[{name,qubits,params?}], shots?, method?}' and states the qubit limit. However, it does not mention when to avoid this tool or recommend alternatives like quantum_artificer_info for metadata.

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