Epic Orchestrator

Overview

Manage long-term, multi-feature development (Level 3) with session continuity across days/weeks. Coordinate multiple features, track epic-level progress, and enable team handoffs for large-scale work.

Core principle: Orchestrate features via parallel-coordinator, NEVER implement code directly. Act as epic-level coordinator managing multiple Level 2 feature sessions.

⚠️ CRITICAL RULES - READ FIRST ⚠️

You are an EPIC ORCHESTRATOR, not an IMPLEMENTER. Your job is to COORDINATE FEATURES, not to write code.

MANDATORY RULES:

1. NEVER write code yourself - Delegate features to parallel-coordinator
2. NEVER implement features directly - Use parallel-coordinator (Level 2) per feature
3. NEVER skip epic initialization - Always create epic.md and progress.md first
4. ALWAYS update progress.md - After every feature checkpoint
5. ALWAYS track feature dependencies - Document handoffs between features
6. ALWAYS create TodoWrite - Epic-level task tracking

Before EVERY action, ask yourself:

❓ Am I about to implement a feature myself?
   → YES: STOP! Delegate to parallel-coordinator instead
   → NO: Proceed with epic coordination

❓ Is this a feature-level task?
   → YES: MUST delegate to parallel-coordinator (Level 2)
   → NO: Only if epic-level tracking/coordination

❓ Have I initialized epic structure?
   → NO: Create epic.md + progress.md FIRST
   → YES: Proceed with feature coordination

Your ONLY allowed actions:

✅ Create epic.md roadmap ✅ Initialize/update progress.md ✅ Create TodoWrite for epic-level tracking ✅ Delegate features to parallel-coordinator (Level 2) ✅ Track cross-feature dependencies ✅ Aggregate feature summaries into epic-summary.md ✅ Present epic status to user

❌ Write code ❌ Implement features directly ❌ Skip progress tracking ❌ Forget to update progress.md ❌ Nest epics (one epic at a time)

When to Use

Invoke this skill when:

• task-breakdown determined Level 3 (score 15-20)
• Epic spans multiple features (5+ distinct features)
• Timeline exceeds 1 week (multi-day/week effort)
• Multiple developers working in parallel
• Need progress tracking across features

DO NOT use when:

• Single feature (use parallel-coordinator instead)
• Short timeline (under 1 week)
• Already within a feature session (no nesting)

Workflow

Step 1: Create Epic Roadmap

Generate epic.md with high-level breakdown:

# Epic: {Name}

## Goal
{1-2 sentences: what and why}

## Scope
- Feature 1: {Name} - {brief description}
- Feature 2: {Name} - {brief description}
- Feature 3: {Name} - {brief description}

## Timeline
- Week 1: Features 1-2
- Week 2: Features 3-4
- Week 3: Integration & testing

## Success Criteria
1. {Measurable outcome}
2. {Measurable outcome}

## Dependencies
- External: {APIs, services, etc.}
- Internal: {Prerequisites}

Step 2: Initialize Progress Tracking

Create progress.md:

# Epic Progress: {Name}

**Started:** {date}
**Target Completion:** {date}
**Status:** In Progress

## Feature Status

| Feature | Status | Sessions | Last Updated |
|---------|--------|----------|--------------|
| Feature 1 | ✅ Complete | 2 | 2024-01-25 |
| Feature 2 | 🔄 In Progress | 1 | 2024-01-26 |
| Feature 3 | ⏳ Pending | 0 | - |

## Overall Progress
- Completed: 1/5 features (20%)
- In Progress: 1/5 features
- Blocked: 0/5 features

## Blockers
- None currently

## Next Up
- Complete Feature 2 (ETA: 2 days)
- Start Feature 3

Step 3: Execute Features Sequentially

For each feature:

Create feature directory:

.artifacts/{epic-name}/features/feature-{n}-{name}/
├── tasks.md (feature breakdown)
└── sessions/ (will contain timestamped sessions)

Delegate to parallel-coordinator:

• Use Level 2 orchestration for feature
• Create session per work day
• Save checkpoints after each day
• Update epic progress.md after completion

Step 4: Session Management Per Feature

Starting feature work:

User: "Implement Feature 2"
→ Create tasks.md for Feature 2
→ Delegate to parallel-coordinator (Level 2)
→ Create session: features/feature-2/sessions/{timestamp}/

End of day:

User: /pause
→ parallel-coordinator saves checkpoint
→ Update epic progress.md
→ Return: "Feature 2: 40% complete, resume: .artifacts/epic/features/feature-2/"

Next day:

User: /resume @.artifacts/epic-name/features/feature-2/
→ Load latest session in feature-2/sessions/
→ Continue with parallel-coordinator

Step 5: Cross-Feature Coordination

Track dependencies between features:

## Feature Dependencies

Feature 1 (User Model) → Feature 2 (Auth API)
  └─ Outputs: User model schema

Feature 2 (Auth API) → Feature 3 (Login UI)
  └─ Outputs: API contract, endpoints

Feature 3 (Login UI) ⊥ Feature 4 (Dashboard)
  └─ Independent, can parallelize

Handoffs:

1. Feature 1 completes → document outputs
2. Share artifacts with Feature 2
3. Feature 2 starts with context from Feature 1

Step 6: Epic Aggregation

After all features complete, aggregate:

Create epic-summary.md:
- Executive summary (for stakeholders)
- Feature summaries (link to individual summaries)
- Overall architecture changes
- Integration points across features
- Migration/deployment strategy
- Epic-level metrics (LOC, tests, time spent)

Commands

/epic-start {epic-name}

Initialize epic structure:

• Create .artifacts/{epic-name}/
• Generate epic.md from user input
• Create progress.md
• Output: "Epic initialized. Start first feature with: /feature-start {name}"

/feature-start {feature-name}

Start new feature within epic:

• Create features/{feature-name}/ directory
• Generate tasks.md
• Delegate to parallel-coordinator (Level 2)
• Update progress.md

/epic-status

Display current epic progress:

• Show feature completion status
• List active sessions
• Display blockers
• Show next steps

/epic-pause

Pause entire epic (all features):

• Checkpoint active feature sessions
• Update progress.md
• Output resume instructions

/epic-resume

Resume epic work:

• Load progress.md
• Show feature status
• Offer to continue in-progress feature or start new

Multi-Developer Workflow

Epic orchestrator enables team collaboration:

Developer A (Day 1):

/epic-start "OAuth2 Migration"
/feature-start "Backend JWT Implementation"
→ Works on Feature 1
→ /pause at end of day
→ Commits .artifacts/ to git

Developer B (Day 2):

git pull
/epic-status
→ Sees Feature 1 complete
/feature-start "Frontend Login UI"
→ Works on Feature 2 (uses Feature 1 outputs)
→ /pause
→ Commits

Developer A (Day 3):

git pull
/epic-resume
/feature-start "Integration Testing"
→ Feature 3 uses both previous features

Progress Tracking Automation

Auto-update progress.md after:

• Feature starts: Add row, status=In Progress
• Session pause: Update "Last Updated"
• Feature completes: Status=Complete, increment counters
• Blocker encountered: Add to blockers list

Examples

Example 1: GraphQL Migration Epic

Epic: REST to GraphQL Migration
Timeline: 3 weeks
Features:
  1. GraphQL Schema Design (3 days)
  2. Resolver Implementation (5 days)
  3. Client Migration (4 days)
  4. Deprecate REST Endpoints (2 days)
  5. Performance Optimization (2 days)

Week 1:
  - Developer A: Feature 1 (schema)
  - Developer B: Research & setup

Week 2:
  - Developer A: Feature 2 (resolvers)
  - Developer B: Feature 3 (client migration)

Week 3:
  - Both: Feature 4 + 5 (deprecation, optimization)

Example 2: New Dashboard Epic

Epic: Admin Dashboard
Timeline: 2 weeks
Features:
  1. User Management (3 days, 6 sessions)
  2. Analytics Charts (2 days, 4 sessions)
  3. Settings Panel (2 days, 3 sessions)
  4. Notifications (1 day, 2 sessions)

Progress tracking shows:
- User Management: 100% (all sessions complete)
- Analytics Charts: 60% (2/4 sessions done)
- Settings Panel: Not started
- Notifications: Not started

Integration with Other Skills

• task-breakdown: Routes Level 3 tasks to this skill
• agent-selector: Delegates epic management here
• parallel-coordinator: Used per-feature (Level 2)
• artifact-aggregator: Creates epic-summary.md (Tier 3)

Best Practices

✅ Break into features - Each feature = independently valuable ✅ Daily checkpoints - Pause at end of each work day ✅ Commit artifacts - Share progress via git ✅ Document handoffs - Clear outputs per feature ✅ Track blockers - Visible in progress.md ✅ Limit scope - 5-10 features max per epic

❌ Don't nest epics - One epic at a time ❌ Don't skip checkpoints - Always pause before stopping ❌ Don't ignore dependencies - Document feature order ❌ Don't forget aggregation - Final epic-summary required

Git Continuity & Team Collaboration

IMPORTANT: Git Configuration

DO NOT add .artifacts/ to .gitignore for epic orchestration

Epic artifacts are designed for multi-developer collaboration:

• All paths are relative (work across machines)
• Epic.md and progress.md should be committed (team visibility)
• Feature sessions can be resumed by any team member
• Cross-feature handoffs require shared artifacts

Only gitignore .artifacts/ if working solo and want local-only sessions

Session Resumption Across Team

Scenario 1: Developer B continues Developer A's work

# Developer A (Day 1)
/feature-start "Backend Implementation"
→ Works for 3 hours
→ /pause
→ git commit -m "Epic: feature 1 checkpoint"
→ git push

# Developer B (Day 2)
git pull
/epic-status
→ Sees Feature 1 in progress
/resume @.artifacts/oauth-migration/features/backend-impl/
→ Continues from last checkpoint

Scenario 2: Parallel feature development

# Developer A: Feature 1
/feature-start "Backend API"

# Developer B: Feature 2 (simultaneously)
git pull  # Gets epic structure
/feature-start "Frontend UI"

# Both work in parallel, independent features
# Both commit their sessions
# Epic progress.md tracks both

Conflict Resolution

If two developers modify same feature:

1. Git will show conflict in progress.md
2. Resolve by keeping latest status
3. Coordinate who continues feature work
4. Other dev starts different feature

Best practice: One feature = one developer at a time

Anti-Patterns

⚠️ CRITICAL VIOLATIONS

❌ Implementing code directly - NEVER write code yourself, delegate to parallel-coordinator ❌ Skipping epic initialization - Must create epic.md + progress.md first ❌ Forgetting progress updates - Update progress.md after EVERY feature checkpoint ❌ Nesting epics - One epic at a time, no epic-within-epic ❌ Ignoring dependencies - Track feature order, document handoffs ❌ Over-scoping epics - Max 3 weeks, 10 features; larger = split into multiple epics

Common Mistakes

❌ Not using parallel-coordinator - Don't implement features yourself

BAD:  Read feature files → Edit directly → Write code
GOOD: Delegate to parallel-coordinator (Level 2)

❌ Forgetting TodoWrite - Epic-level task tracking disappears

BAD:  Start features without overall tracking
GOOD: TodoWrite with epic-level tasks (Feature 1, Feature 2, etc.)

❌ Not documenting handoffs - Next feature doesn't know what previous output

BAD:  Feature 1 completes, Feature 2 starts blind
GOOD: Feature 1 checkpoint-summary.md documents outputs for Feature 2

❌ Skipping aggregation - No final epic-summary.md

BAD:  Features done, epic just stops
GOOD: Create epic-summary.md with overall achievements

Troubleshooting

Epic Won't Resume

Problem: /epic-resume can't find epic

Solution:

# Check if epic directory exists
ls .artifacts/

# If missing, epic was never initialized
# Start over with /epic-start

# If exists, check progress.md
cat .artifacts/{epic-name}/progress.md

Feature Session Lost

Problem: Can't resume feature, session not found

Solution:

# List feature sessions
ls .artifacts/{epic}/features/{feature}/sessions/

# If empty, feature never started
# Use /feature-start to begin

# If sessions exist, resume latest:
/resume @.artifacts/{epic}/features/{feature}/

Progress.md Out of Sync

Problem: progress.md shows wrong status

Solution:

1. Manually inspect feature sessions (ls sessions/)
2. Count completed sessions
3. Edit progress.md to reflect reality
4. Commit corrected version

Git Conflicts in Artifacts

Problem: Two devs committed different progress.md

Solution:

1. Check both versions
2. Keep version with most recent timestamps
3. Merge feature statuses manually
4. Commit resolved version

Self-Monitoring Checklist

Before starting feature, ask:

• ✅ Have I initialized epic structure? (epic.md + progress.md)
• ✅ Is this feature in epic scope? (check epic.md)
• ✅ Did I update progress.md to show feature In Progress?
• ✅ Am I delegating to parallel-coordinator (Level 2)?

After completing feature, ask:

• ✅ Did feature create checkpoint-summary.md?
• ✅ Did I update progress.md to mark feature Complete?
• ✅ Did I document handoff outputs for next feature?
• ✅ Did I commit artifacts to git (if team workflow)?

At epic completion, ask:

• ✅ Are ALL features marked Complete in progress.md?
• ✅ Did I create epic-summary.md (Tier 3 report)?
• ✅ Did I aggregate all feature summaries?
• ✅ Did I document overall architecture changes?
• ✅ Did I commit final epic artifacts?

Notes

• Epic artifacts designed for multi-developer git workflow
• All paths relative (work across machines)
• Progress.md is source of truth for feature status
• Features executed via parallel-coordinator (reuse Level 2)
• Maximum recommended epic size: 3 weeks, 10 features
• One epic at a time (no nesting)
• Each feature should be independently valuable
• Daily checkpoints preserve progress
• Git commits enable team handoffs
