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

Annotations already declare idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds real value beyond that: 'Local software evidence only' (no hardware execution), a 4096-operation cap and a 65536-byte request cap, plus the shape of the returned evidence. It omits the pricing implication of the required max_total_price parameter, which is the one significant gap.

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?

A tight four-label Problem/Input/Result/Limits structure, front-loaded with purpose and ending with hard numeric limits. Every clause carries information; nothing is redundant with the title or name.

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 the description need not enumerate return values, and it still summarizes them helpfully. However, for a 4-required-parameter tool with 0% schema coverage and a payment-flavored max_total_price const, the definition leaves the required-parameter contract and the idempotency/price semantics unexplained.

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 full burden. It names three fields (qubit count, operations, target) that live inside the nested 'request' object, but it never explains the two other required top-level parameters, idempotency_key and max_total_price, nor the required schema_version const. Half the required input surface is undocumented in both places.

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+resource ('Compile this bounded circuit to the supplied pinned provider target') and the returned evidence type, which is enough to separate it from siblings like quantum_provider_readiness_check_v1 or quantum_execution_plan_select_v1. It stops short of naming any sibling, so differentiation is inferred rather than stated.

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?

There is no when-to-use/when-not guidance and no mention of the alternatives in this crowded family of ~14 quantum_* tools. The phrase 'bounded circuit' hints at a precondition but never states what qualifies or which sibling to use instead when the circuit is not bounded.

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