fusion-plan

Produce a high-confidence, CONCISE implementation / architecture / strategy PLAN that follows the OMC plan system end to end. It first runs OMC's real requirements interview (auto-chains the omc-plan skill: one question at a time, explore-first, Analyst consult) to produce an initial plan in .omc/plans/, then DEEPENS that plan with a 3-round ITERATIVE fusion loop — each round an Opus 4.8 panelist (Agent subagent) and a GPT-5.5 panelist (via codex) critique/improve it IN PARALLEL and BLIND, then Opus 4.8 (the orchestrator) judges and synthesizes one tighter plan that seeds the next round, stopping early on convergence. Writes the final dense plan back to the same .omc/plans/<slug>.md, then offers the OMC handoff (/omc-plan --review → /team or /ralph). Use for high-stakes planning, architecture decisions, strategy calls, and hard debugging — especially when the user runs /plan or asks how to approach a non-trivial build. Reuses the fusion skill's run_codex.sh + judge rubric. NOT for trivial tasks (single pass is enough).
