/new-milestone | get-shit-done

<objective> Create a new milestone for an existing project with defined phases.

Purpose: After completing a milestone (or when ready to define next chunk of work), creates the milestone structure in ROADMAP.md with phases, updates STATE.md, and creates phase directories. Output: New milestone in ROADMAP.md, updated STATE.md, phase directories created </objective>

<execution_context> @~~/.claude/get-shit-done/workflows/create-milestone.md @~~/.claude/get-shit-done/templates/roadmap.md </execution_context>

<context> Milestone name: $ARGUMENTS (optional - will prompt if not provided)

Load project state first: @.planning/STATE.md

Load roadmap: @.planning/ROADMAP.md

Load milestones (if exists): @.planning/MILESTONES.md </context>

<process> 1. Load project context (STATE.md, ROADMAP.md, MILESTONES.md) 2. Calculate next milestone version and starting phase number 3. If milestone name provided in arguments, use it; otherwise prompt 4. Gather phases (per depth setting: quick 3-5, standard 5-8, comprehensive 8-12): - If called from /gsd:discuss-milestone, use provided context - Otherwise, prompt for phase breakdown 5. Detect research needs for each phase 6. Confirm phases (respect config.json gate settings) 7. Follow create-milestone.md workflow: - Update ROADMAP.md with new milestone section - Create phase directories - Update STATE.md for new milestone - Git commit milestone creation 8. Offer next steps (discuss first phase, plan first phase, review) </process>
