Emergency Incident Response

Date: 2025-10-26 Issue: Self-hosted Windows runner file lock Duration: ~2 hours (detection to resolution)

Timeline

  1. Detection (2025-10-26 afternoon): PR #160 CI failures with AccessDeniedException on Android SDK jar
  2. Initial Response: Multiple cleanup attempts (Gradle daemons, Java processes, file ownership)
  3. Escalation: Discovered conflicting runner configurations, removed problematic runner
  4. Pause: All 3 agents notified with clear pause messages
  5. Emergency Agent Deployed: Comprehensive mission document created
  6. Root Cause Identified: local.properties with hardcoded SDK path + orphaned Java processes
  7. Resolution: Agent 1 removed local.properties, emergency agent created fresh isolated runners
  8. Verification: PR #160 merged successfully after fix

Root Cause

Primary Issues:

  1. local.properties committed to git with hardcoded SDK path (C:\Users\chris_3zal3ta\AppData\Local\Android\Sdk)
  2. Orphaned Java/Gradle processes holding file locks on core-lambda-stubs.jar
  3. Misconfigured runner names (“SOLACE” instead of proper naming)
  4. No workspace isolation between runner jobs

Contributing Factors:

  • Windows file locks persisting across process terminations
  • Self-hosted runner reusing same SDK directories
  • No monitoring for orphaned processes

Resolution

Phase 1: Clear File Locks

  • Killed all orphaned Java/Gradle processes
  • Restarted runner services

Phase 2: Remove Misconfigured Runners

  • Removed old runners (IDs 21, 22) from GitHub
  • Cleared runner directories

Phase 3: Create Fresh Isolated Runners

  • Used setup-self-hosted-runners.ps1 script
  • Created 3 isolated runners (2 for main repo, 1 for docs repo)
  • Separate _work directories per runner
  • Unique Gradle caches per runner

Phase 4: Install as Services

  • Windows services for auto-start
  • Proper naming convention (win-runner-01, win-runner-02, docs-runner-01)

Phase 5: Documentation

  • Incident report: docs/SELF_HOSTED_RUNNER_INCIDENT_2025-10-26.md
  • Setup guide: docs/SELF_HOSTED_RUNNER_SETUP.md
  • Emergency protocol: docs/AGENT_MESSAGES/WEEK_9/EMERGENCY_RUNNER_FIX.md
  • Updated CLAUDE.md with troubleshooting section

Prevention Measures

  1. Added to .gitignore: local.properties (prevent future commits)
  2. Runner Setup Script: Automated provisioning with isolation
  3. Monitoring: Documented cleanup procedures for orphaned processes
  4. Documentation: Comprehensive incident report for future reference

Process Improvements

1. PR Title Convention

Format: [AGENT-ID] Descriptive Title

  • [AAP] = Agent 1 (Platform)
  • [AAM] = Agent 2 (Modules)
  • [AAA] = Agent 3 (Analysis)
  • [Agent-O] = Orchestrator

Benefits:

  • Quick identification of agent ownership
  • Easy PR filtering in GitHub (is:pr [AAM])
  • Clear review assignment
  • Better retrospectives

Implementation: PR #161 (merged 2025-10-26T23:41:22Z)

2. Multi-Agent Communication Protocol

Hybrid System:

  • File-based messages (>30 lines): Stored in docs/AGENT_MESSAGES/WEEK_N/agent-X/
  • Inline delimiters (<30 lines): Direct prompts with ----StartPrompt(AGENT)---- markers
  • Status tracking: In file headers (READY, SENT, CANCELLED, COMPLETED)
  • Lifecycle management: Update message status after execution

Benefits:

  • Better organization and searchability
  • Clear message ownership and timeline
  • Easier context resumption
  • Version control for agent communications

Implementation: PR #163 (merged 2025-10-27T01:54:30Z)

3. End-of-Day Documentation Protocol

New Workflow:

  • Each agent updates their context document at end of day
  • Creates Obsidian vault entry summarizing work
  • Updates message file with execution summary for Agent O
  • Creates 2 PRs (context update + vault entry)

Benefits:

  • Clear session boundaries
  • Better handoff between sessions
  • Preserved context for resumption
  • Automatic vault documentation

Agent O reads summaries at start: Added to AGENT_O_ORCHESTRATOR.md session resume protocol

4. Obsidian Vault Workflow Clarified

Correct Process:

  1. Create PR in archery-apprentice-docs repo
  2. User reviews and merges
  3. GitHub Actions auto-deploys to vault
  4. Never run deploy.ps1 manually

Benefits:

  • PR review before deployment
  • Automatic deployment (no manual steps)
  • Clear workflow documented

What Could Be Better 🔧

  1. Runner Stability:

    • Need monitoring for orphaned Java processes
    • Consider periodic runner health checks
    • Automate cleanup procedures
    • Better error detection (catch issues faster)

  2. local.properties:

    • Should have been in .gitignore from start
    • Add to agent onboarding checklist
    • Prevent accidental commits of machine-specific config

  3. Emergency Detection:

    • Could detect CI failures faster (alert after 2-3 failures)
    • Consider automated notifications
    • Better visibility into runner health

  4. Agent Communication:

    • Agent 3 initially misunderstood end-of-day cleanup task
    • Could make instructions even clearer
    • Consider templates for common responses

Key Learnings 📚

  1. Agent Collaboration Multiplies Value:

    • Agent 3’s prep work directly enabled Agent 2’s efficiency
    • Cross-agent coordination saved 3-4 hours
    • Proactive analysis prevents wasted effort
    • Lesson: Always look for opportunities to prepare ahead

  2. Infrastructure Matters:

    • Self-hosted runners need isolated workspaces
    • Windows file locks can persist across processes
    • Fresh runner creation often faster than debugging
    • Lesson: Don’t hesitate to rebuild infrastructure when troubleshooting stalls

  3. Documentation Pays Off:

    • Obsidian vault workflow now clear (no more confusion)
    • Context documents critical for session resumption
    • Incident reports prevent repeating mistakes
    • End-of-day summaries improve handoff
    • Lesson: Invest in documentation during incidents, not just after

  4. Clear Ownership Works:

    • PR title convention ([AGENT-ID]) improved visibility
    • Easy to see who owns what
    • Faster coordination decisions
    • Lesson: Simple conventions have outsized impact

  5. Emergency Protocols:

    • Pause notifications preserved agent context
    • File-based messages worked well for complex instructions
    • Emergency agent mission document provided clear guidance
    • Lesson: Pre-planned emergency procedures reduce stress and confusion
