refine-plan

# Refine Plan Loop the review pipeline over a planning artifact until no new findings are accepted. Writes back to the artifact file(s) in place. Supports plans, shells, and specs. ## Task Tracking At the start of every invocation (including re-runs from Step 5), use `TaskCreate` to create a task for each step: 1. Resolve the artifact 2. Run `/review-plan` skill 3. Run `/evaluate-findings` skill 4. Run `/apply-findings` skill 5. Re-run `/refine-plan` skill if changed ## Step 1: Resolve the Artifact ### Determine Artifact Type 1. **Explicit argument** — If the user specified a type (e.g., "refine plan", "refine shells", "refine spec"), use it 2. **Conversation context** — Infer from conversation (e.g., if `/draft-plan` just ran, type is plan) 3. **Auto-detect** — Check `.turbo/` for existing artifacts. If multiple types exist, use `AskUserQuestion` ### Resolve the Artifact File(s) #### Plan 1. **Explicit path** — use it 2. **Explicit slug** — resolve to `.turbo/plans/<slug>.md` 3. **Single file** — Glob `.turbo/plans/*.md`. If exactly one file exists, use it 4. **Most recent** — most recently modified file 5. **Legacy fallback** — `.turbo/plan.md` if `.turbo/plans/` does not exist 6. **Nothing found** — tell the user to run `/turboplan` (for a new task) or `/pick-next-shell` (for existing shells) and stop #### Shells 1. **Explicit spec slug** — Glob `.turbo/shells/<slug>-*.md` 2. **Explicit spec path** — derive slug from filename, glob as above 3. **Single spec** —...
