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

Annotations supply the safety profile (idempotentHint=true, destructiveHint=false, openWorldHint=false) and the description adds genuine operating limits: local software evidence only, 3 verification qubits, 65536 request bytes. However, it doesn't explain why readOnlyHint=false for what is framed as an audit, leaving a notable behavioral trait undisclosed.

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 scaffold is front-loaded and scannable, but the 'metric and....' fragment is truncated and incomplete, undercutting the structure. Otherwise reasonably compact.

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 return values need not be explained, and the stated limits add useful framing. Still, with zero parameter documentation and no routing guidance against many similar siblings, the definition leaves real gaps for an agent preparing a call.

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 must carry parameter meaning, yet it only hints at 'original circuit, candidate circuit' (nested inside request) and omits schema_version, idempotency_key, and max_total_price entirely. With four required parameters effectively undocumented, the description compensates only partially.

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?

States a specific verb and resource: audit candidate optimization equivalence and coupling preservation. It distinguishes itself somewhat from generic siblings like compare_quantum_circuits or audit_quantum_transformation by naming 'optimization equivalence' and 'qualitative coupling preservation', though it doesn't explicitly contrast them.

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?

No when-to-use guidance and no comparison to alternatives, despite a crowded sibling set (quantum_verified_circuit_optimization_v1, audit_quantum_transformation, compare_quantum_circuits) that an agent must disambiguate against. The description never states the conditions that select this tool.

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