Coordination Patterns

Daily Standup Pattern

Morning Check-In (9 AM):

  • Status: What did you complete yesterday?
  • Today: What will you work on today?
  • Blockers: Do you need help with anything?

Evening Wrap-Up (5 PM):

  • Completed: What did you finish today?
  • Next: What’s your next task?
  • PRs: Any PRs ready for review?

PR Review Pattern

Reviewers:

  • Agent 2 reviews architecture and patterns
  • Agent 3 reviews test coverage
  • Agent O reviews orchestration impact
  • User final approval and merge

Review Checklist:

  • Interface design clear
  • Implementation follows best practices
  • Test coverage ≥ 90%
  • Documentation complete
  • Build passes
  • No regressions

Session Wrap-Up Pattern

Process (tonight’s implementation):

  1. Each agent updates context file (Session Resume Point)
  2. Each agent creates Obsidian PR (work summary)
  3. Result: 8 PRs (4 context + 4 Obsidian)
  4. Tomorrow: Merge all 8 PRs, resume fresh session

Benefits:

  • Clean session end/resume
  • Clear audit trail (8 separate PRs)
  • Easy session resumption (Session Resume Points)

Quality Metrics

PR Merge Success

  • 7 PRs merged: #144, #149, #150, #151, #152, #153, #154 (pending)
  • 1 merge conflict (PR #150, resolved)
  • 0 PRs rejected or reverted
  • 100% merge success rate

Test Suite Health

  • All tests passing (2051+ tests)
  • Coverage: 81% → 84-85% (+3-4%)
  • 0 regressions introduced
  • Test execution: stable (~90s)

Agent Task Completion

  • Agent 1: 100% (Week 7-8 goals met)
  • Agent 2: 100% (Week 6-7 goals met)
  • Agent 3: 100% (Week 7-8 goals met)
  • Overall: 100% completion rate

Velocity Metrics

  • Week 5: 1 PR merged
  • Week 6: 2 PRs merged
  • Week 7: 2 PRs merged
  • Week 8: 2 PRs merged
  • Average: 2 PRs/week (consistent)

Lessons Learned

What Worked Well

  1. Session Resume Points

    • Clean session end/resume pattern
    • Easy to pick up where we left off
    • No context loss between sessions
  2. Parallel Work

    • 3 agents working simultaneously
    • No conflicts (separate work streams)
    • Faster overall progress
  3. Cross-Agent Reviews

    • Agents reviewing each other
    • High quality (multiple perspectives)
    • Shared knowledge across agents
  4. Documentation First

    • Planning before implementation
    • No rework needed
    • Clear roadmap (Week 9-10)

What Could Improve

  1. PR Merge Timing

    • Some PRs sat for 24+ hours
    • Could merge faster (same day)
    • Faster feedback loop
  2. Dependency Tracking

    • Manual tracking of cross-agent dependencies
    • Could use better tools (dependency matrix)
    • Prevent blocking scenarios
  3. Automation

    • Session wrap-up is manual (8 PRs)
    • Could automate (script for PR creation)
    • Save time on repetitive tasks

Week 9 Adjustments

  1. Daily Merges: Merge PRs same day (faster feedback)
  2. Dependency Matrix: Track Agent 1 ↔ Agent 2 ↔ Agent 3 dependencies explicitly
  3. Automated Wrap-Up: Consider script for session wrap-up PRs
