Imported from davepoon/buildwithclaude (plugins/gsd/skills/complete-milestone/SKILL.md). Install upstream with npx skills add davepoon/buildwithclaude --skill complete-milestone. Copyright stays with the author.

Purpose: Create historical record of shipped version, archive milestone artifacts (roadmap + requirements), and prepare for next milestone. Output: Milestone archived (roadmap + requirements), PROJECT.md evolved, git tagged.

<execution_context> Load these files NOW (before proceeding):

• @${CLAUDE_PLUGIN_ROOT}/workflows/complete-milestone.md (main workflow)
• @${CLAUDE_PLUGIN_ROOT}/templates/milestone-archive.md (archive template) </execution_context>

User input:

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

Follow complete-milestone.md workflow:

0. Check for audit:

   • Look for .planning/v{{version}}-MILESTONE-AUDIT.md
   • If missing or stale: recommend /gsd:audit-milestone first
   • If audit status is gaps_found: recommend /gsd:plan-milestone-gaps first
   • If audit status is passed: proceed to step 1

   ## Pre-flight Check
   
   {If no v{{version}}-MILESTONE-AUDIT.md:}
   ⚠ No milestone audit found. Run `/gsd:audit-milestone` first to verify
   requirements coverage, cross-phase integration, and E2E flows.
   
   {If audit has gaps:}
   ⚠ Milestone audit found gaps. Run `/gsd:plan-milestone-gaps` to create
   phases that close the gaps, or proceed anyway to accept as tech debt.
   
   {If audit passed:}
   ✓ Milestone audit passed. Proceeding with completion.

1. Verify readiness:

   • Check all phases in milestone have completed plans (SUMMARY.md exists)
   • Present milestone scope and stats
   • Wait for confirmation

2. Gather stats:

   • Count phases, plans, tasks
   • Calculate git range, file changes, LOC
   • Extract timeline from git log
   • Present summary, confirm

3. Extract accomplishments:

   • Read all phase SUMMARY.md files in milestone range
   • Extract 4-6 key accomplishments
   • Present for approval

4. Archive milestone:

   • Create .planning/milestones/v{{version}}-ROADMAP.md
   • Extract full phase details from ROADMAP.md
   • Fill milestone-archive.md template
   • Update ROADMAP.md to one-line summary with link

5. Archive requirements:

   • Create .planning/milestones/v{{version}}-REQUIREMENTS.md
   • Mark all v1 requirements as complete (checkboxes checked)
   • Note requirement outcomes (validated, adjusted, dropped)
   • Delete .planning/REQUIREMENTS.md (fresh one created for next milestone)

6. Update PROJECT.md:

   • Add "Current State" section with shipped version
   • Add "Next Milestone Goals" section
   • Archive previous content in <details> (if v1.1+)

7. Commit and tag:

   • Stage: MILESTONES.md, PROJECT.md, ROADMAP.md, STATE.md, archive files
   • Commit: chore: archive v{{version}} milestone
   • Tag: git tag -a v{{version}} -m "[milestone summary]"
   • Ask about pushing tag

8. Offer next steps:

   • /gsd:new-milestone — start next milestone (questioning → research → requirements → roadmap)

<output_format> After the milestone is archived and tagged, emit a Milestone Complete continuation block following the pattern in references/continuation-format.md (§ Milestone Complete variant):

• ## 🎉 Milestone v{{version}} Complete with phase/plan/task summary
• Brief one-paragraph "what shipped" recap
• ## ▶ Next Up heading
• Use `/clear` then: before /gsd:new-milestone
• Parenthetical: (/clear is safe — /gsd:resume-work restores position from HANDOFF.json if you change your mind)
• Optional "Also available:" with /gsd:audit-milestone (retrospective audit) or /gsd:review-backlog (deferred items review)

Milestone close is the single biggest context-shed point in the workflow. The just-shipped milestone's plan/execute conversation is finished; the next milestone wants a clean slate. Always suggest /clear. </output_format>

<success_criteria>

• Milestone archived to .planning/milestones/v{{version}}-ROADMAP.md
• Requirements archived to .planning/milestones/v{{version}}-REQUIREMENTS.md
• .planning/REQUIREMENTS.md deleted (fresh for next milestone)
• ROADMAP.md collapsed to one-line entry
• PROJECT.md updated with current state
• Git tag v{{version}} created
• Commit successful
• User knows next steps (including need for fresh requirements) </success_criteria>

<critical_rules>

• Load workflow first: Read complete-milestone.md before executing
• Verify completion: All phases must have SUMMARY.md files
• User confirmation: Wait for approval at verification gates
• Archive before deleting: Always create archive files before updating/deleting originals
• One-line summary: Collapsed milestone in ROADMAP.md should be single line with link
• Context efficiency: Archive keeps ROADMAP.md and REQUIREMENTS.md constant size per milestone
• Fresh requirements: Next milestone starts with /gsd:new-milestone which includes requirements definition </critical_rules>
