Gsd Complete Milestone

User input:

• Version: {{milestone-version}} (e.g., "1.0", "1.1", "2.0")

Check if milestone is complete by counting phases with SUMMARY.md files:

# Count completed plans
ls .planning/phases/*/SUMMARY.md 2>/dev/null | wc -l

# Check ROADMAP for milestone scope
cat .planning/ROADMAP.md

Present milestone scope and stats to user.

Use AskUserQuestion to get combined readiness + archive confirmation:

Tool: AskUserQuestion

• header: "Ready to Complete Milestone?"
• question: "Complete v{{milestone-version}}? This will archive all files to history/v{{milestone-version}}/"
• details: Show milestone stats:
  • Number of phases completed
  • Number of plans completed
  • Key accomplishments (extracted from SUMMARYs)
• options:
  • "Complete and archive" — Archive to history/ and mark complete
  • "Cancel" — Exit without changes

If "Cancel": Exit with message "Milestone completion cancelled."

If "Complete and archive": Continue to next step.

Archive all milestone files directly to history/v{{milestone-version}}/ using bash commands:

# Source git helpers
if ! type commit_as_user >/dev/null 2>&1; then
    source .github/get-shit-done/workflows/git-identity-helpers.sh
fi

# Create destination with mirrored structure
mkdir -p .planning/history/v{{milestone-version}}/

# Move required files atomically
mv .planning/ROADMAP.md .planning/history/v{{milestone-version}}/
mv .planning/STATE.md .planning/history/v{{milestone-version}}/
mv .planning/PROJECT.md .planning/history/v{{milestone-version}}/

# Move optional files (don't fail if missing)
mv .planning/REQUIREMENTS.md .planning/history/v{{milestone-version}}/ 2>/dev/null || true

# Move directories (preserves structure)
mv .planning/phases .planning/history/v{{milestone-version}}/ 2>/dev/null || true
mv .planning/research .planning/history/v{{milestone-version}}/ 2>/dev/null || true
mv .planning/todos .planning/history/v{{milestone-version}}/ 2>/dev/null || true

# Stage all changes
git add .planning/history/v{{milestone-version}}/
git add -u .planning/  # Stages deletions

# Commit with user identity
commit_as_user "milestone: archive v{{milestone-version}} to history

Moved to .planning/history/v{{milestone-version}}/:
- ROADMAP.md, STATE.md, PROJECT.md
- REQUIREMENTS.md
- phases/, research/, todos/

Workspace ready for next milestone."

Note: All operations are atomic at filesystem level (mv appears instantly or not at all).

Update .planning/MILESTONES.md with new entry (create if doesn't exist):

# Extract milestone name from ROADMAP.md (now in history/)
MILESTONE_NAME=$(grep "^# " .planning/history/v{{milestone-version}}/ROADMAP.md | head -1 | sed 's/^# //')

# Count phases and plans
PHASE_COUNT=$(find .planning/history/v{{milestone-version}}/phases -name "SUMMARY.md" 2>/dev/null | cut -d/ -f5 | cut -d- -f1 | sort -u | wc -l)
PLAN_COUNT=$(find .planning/history/v{{milestone-version}}/phases -name "SUMMARY.md" 2>/dev/null | wc -l)

# Extract key accomplishments from SUMMARYs
# (AI: Read 3-5 SUMMARY files and extract major accomplishments)

# Append to registry
cat >> .planning/MILESTONES.md << EOF

## v{{milestone-version}} — ${MILESTONE_NAME}

**Completed:** $(date +%Y-%m-%d)
**Phases:** ${PHASE_COUNT}
**Plans:** ${PLAN_COUNT}

**Key Accomplishments:**
- [ACCOMPLISHMENT_1]
- [ACCOMPLISHMENT_2]

**Location:** .planning/history/v{{milestone-version}}/

git add .planning/MILESTONES.md
commit_as_user "milestone: register v{{milestone-version}} completion"

Use AskUserQuestion to offer optional git tag:

Tool: AskUserQuestion

• header: "Git Tag"
• question: "Create git tag v{{milestone-version}}?"
• options:
  • "Create tag v{{milestone-version}}" — Tag this version
  • "Skip tag" — No git tag

If "Create tag v{{milestone-version}}":

git tag v{{milestone-version}}
echo "Tag v{{milestone-version}} created locally."
echo "To push: git push origin v{{milestone-version}}"

If "Skip tag": Continue to next step.
