What problem does it solve? Greenfield projects need a buildable skeleton before any domain code can compile, and a test gate that silently skips modules produces vacuously green builds. This Skill realizes the wave-0 scaffold — build files, module structure, plugins, and config — and proves the gate actually discriminates red-green before owner blocks begin. ## Core Features & Use Cases - Skeleton generation: Creates the build entry (wrapper, build descriptor), module structure from the architecture map, and pinned plugins/dev-deps required by the stack ADR, with zero domain logic. - Gate discrimination proof: Plants a failing probe test in each guarded module, verifies the gate goes red then green, and records the evidence in a gate-proof/<side>.md file for the worker-composer's Phase 1. - Contract and UI wiring: Honors the profile's run binding for UI sides, creates event-schema contract locations, and wires dependency-lint config (Konsist/ArchUnit, dependency-cruiser) so checks execute from wave 0. - Use Case: In a mismAgent build, the worker-composer dispatches this block first so that every later aggregate, port, or UI block compiles against a skeleton whose gate is proven to catch failures. ## Quick Start Ask the worker to realize the scaffold block for the current feature side so the gate runs green on the empty skeleton with a recorded red-green proof.
