What problem does it solve? Committing engineering time to a half-baked design is expensive. This Skill runs only the design half of the Harness 7-agent pipeline — Requirement Analyst, Solution Architect, and Gate Reviewer — and stops with a verdict before any code is written, so you can validate an architecture before building it. ## Core Features & Use Cases - Design-only pipeline: Dispatches stages 1-3 (RA, SA, GR) and produces 01_REQUIREMENT_ANALYSIS.md, 02_SOLUTION_DESIGN.md, and 03_GATE_REVIEW.md with an APPROVED / CHANGES REQUIRED / REJECTED verdict. - Resumable output: Running the full /harness pipeline later on the same task slug detects the existing 01-03 documents and skips directly to Development. - Task decomposition discipline: Splits designs into tracer-bullet vertical slices sized to fit one model reasoning window, with real consumption dependencies only. - Use Case: You have a feature idea and want an architecture review before a sprint. Run the plan mode to get a gate-reviewed design document set, then hand approved designs to the full pipeline when ready. ## Quick Start Ask the AI to run harness-plan on your feature idea to produce a requirement analysis, solution design, and gate review verdict without writing any code.
