logical-coupler-design skillA

logical-coupler-design is agent-read markdown (skill) from qutone/lightstim: Design a new LogicalCouplerProtocol in LightStim to implement inter-patch joint measurements (lattice surgery). Use this skill when the user wants to: implement a new logical coupler for a code that doesn't have one yet, understand how the Unrotated Surface Code coupler works internally, design a coupler for a new code family (e.g. BB code logical measurement), or extend an existing coupler with a new boundary configuration. This skill is the key to replicating papers that describe custom "logic.
