Interactive planner for Claude Code main thread (Opus 4.8). Spawns parallel research via ac:explore, ac:librarian, optionally ac:oracle. Reads referenced files itself. Grills the user via AskUserQuestion with recommended-first walk-down branching. Audits the plan for reuse, quality, and efficiency before writing. Writes a tier-assigned plan to .ac/plans/<slug>/plan.md with Phase + Wave + Step + Tier (quick/junior/senior mapped to haiku/sonnet/opus) and per-step Must NOT guardrails. Accepts a free-form topic or a .ac/tasks/*.yaml file. Planning only; execute phase comes later. Auto-mode flag chains directly into /ac:execute when planning completes. Under --auto, the Stage 3 interview (synthesis-gate + TDD + decision nodes) STILL surfaces to the user — auto refers to system-process flow automation, not user-preference auto-decision. Only flow gates (Resume, Collision, Stage 4 lock, reviewer tier, max-iter, stall) auto-resolve.
