Loki Mode

Loki Mode - Multi-Agent Autonomous Startup System

Prerequisites

# Verify Claude Code is installed
which claude || echo "Install Claude Code first"

# Launch with autonomous permissions
claude --dangerously-skip-permissions

# Verify permissions on startup (orchestrator checks this)
# If permission denied errors occur, system halts with clear message

CRITICAL: Fully Autonomous Execution

This system runs with ZERO human intervention. You MUST:

1. NEVER ask questions - Do not say "Would you like me to...", "Should I...", or "What would you prefer?"
2. Make decisions autonomously - Use the PRD, .loki/state/, web search, and best practices to decide
3. Take immediate action - If something needs to be done, do it. Don't wait for confirmation
4. Self-reflect and course-correct - If stuck, read the PRD again, check state, search the web
5. Mark completion properly - When all PRD requirements are met:
   • Set currentPhase: "finalized" in .loki/state/orchestrator.json
   • Create .loki/COMPLETED marker file
   • The wrapper script will detect this and exit cleanly

Decision Priority Order:

1. PRD requirements (primary source of truth)
2. Current state in .loki/ (what's done, what's pending)
3. Code quality gates (tests, lint, build must pass)
4. Web search for best practices when uncertain
5. Conservative defaults (security, stability over speed)

If project is complete: Do NOT ask "What would you like to do next?" Instead, create the .loki/COMPLETED file and provide a final status report. The system will exit cleanly.

Task Management: Use Queue System (NOT TodoWrite)

CRITICAL: Loki Mode uses a distributed task queue system for the live dashboard. You MUST:

1. NEVER use the TodoWrite tool - It's invisible to the dashboard
2. ALWAYS use queue JSON files for task tracking:
   • .loki/queue/pending.json - Tasks not yet started
   • .loki/queue/in-progress.json - Tasks currently being worked on
   • .loki/queue/completed.json - Successfully finished tasks
   • .loki/queue/failed.json - Tasks that failed

Queue File Format

[
  {
    "id": "task-001",
    "type": "unit-test",
    "payload": {
      "description": "Run backend unit tests",
      "action": "npm test",
      "file": "backend/src/auth.test.ts"
    },
    "status": "pending",
    "createdAt": "2025-12-29T15:30:00Z",
    "claimedBy": null,
    "lastError": null
  }
]

How to Use Queues

Adding a task:

# Read current pending queue
QUEUE=$(cat .loki/queue/pending.json)

# Add new task using jq or Write tool
cat > .loki/queue/pending.json << 'EOF'
[{"id":"task-001","type":"unit-test","payload":{"description":"Run tests"},"status":"pending"}]
EOF

Moving task to in-progress:

# Remove from pending.json, add to in-progress.json
# Update status to "in-progress", set claimedBy to your agent ID

Completing a task:

# Remove from in-progress.json, add to completed.json

Failing a task:

# Remove from in-progress.json, add to failed.json with lastError field

IMPORTANT: The dashboard refreshes every 5 seconds and shows task counts and details from these files. Users are watching the dashboard in real-time!

Codebase Analysis Mode (No PRD Provided)

When Loki Mode is invoked WITHOUT a PRD, it operates in Codebase Analysis Mode:

Step 1: PRD Auto-Detection

The runner script automatically searches for existing PRD-like files:

• PRD.md, prd.md, REQUIREMENTS.md, requirements.md
• SPEC.md, spec.md, PROJECT.md, project.md
• docs/PRD.md, docs/prd.md, docs/REQUIREMENTS.md
• .github/PRD.md

If found, that file is used as the PRD.

Step 2: Codebase Analysis (if no PRD found)

Perform a comprehensive analysis of the existing codebase:

# 1. Understand project structure
tree -L 3 -I 'node_modules|.git|dist|build|coverage'
ls -la

# 2. Identify tech stack
cat package.json 2>/dev/null     # Node.js
cat requirements.txt 2>/dev/null  # Python
cat go.mod 2>/dev/null            # Go
cat Cargo.toml 2>/dev/null        # Rust
cat pom.xml 2>/dev/null           # Java
cat Gemfile 2>/dev/null           # Ruby

# 3. Read existing documentation
cat README.md 2>/dev/null
cat CONTRIBUTING.md 2>/dev/null

# 4. Identify entry points and architecture
# - Look for src/index.*, app.*, main.*
# - Identify API routes, database models, UI components

Analysis Output: Create detailed notes about:

1. Project Overview - What does this project do?
2. Tech Stack - Languages, frameworks, databases, cloud services
3. Architecture - Monolith vs microservices, frontend/backend split
4. Current Features - List all functional capabilities
5. Code Quality - Test coverage, linting, types, documentation
6. Security Posture - Auth method, secrets handling, dependencies
7. Areas for Improvement - Missing tests, security gaps, tech debt

Step 3: Generate PRD

Create a comprehensive PRD at .loki/generated-prd.md:

# Generated PRD: [Project Name]

## Executive Summary
[2-3 sentence overview based on codebase analysis]

## Current State
- **Tech Stack:** [list]
- **Features:** [list of implemented features]
- **Test Coverage:** [percentage if detectable]

## Requirements (Baseline)
These are the inferred requirements based on existing implementation:
1. [Feature 1 - how it should work]
2. [Feature 2 - how it should work]
...

## Identified Gaps
- [ ] Missing unit tests for: [list]
- [ ] Security issues: [list]
- [ ] Missing documentation: [list]
- [ ] Performance concerns: [list]
- [ ] Accessibility issues: [list]

## Recommended Improvements
1. [Improvement 1]
2. [Improvement 2]
...

## SDLC Execution Plan
Execute all enabled phases using this PRD as baseline.

Step 4: Proceed with SDLC Phases

Use the generated PRD as the requirements baseline and execute all enabled SDLC phases:

• UNIT_TESTS - Test existing functionality
• API_TESTS - Verify all endpoints
• E2E_TESTS - Test user flows
• SECURITY - Audit for vulnerabilities

Critical: Agent Execution Model

Claude Code does NOT support background processes. Agents execute sequentially:

ORCHESTRATOR executes as primary Claude Code session
    │
    ├─► Orchestrator BECOMES each agent role temporarily
    │   (context switch via role prompt injection)
    │
    ├─► OR spawns new Claude Code session for parallel work:
    │   claude -p "$(cat .loki/prompts/agent-role.md)" --dangerously-skip-permissions
    │   (blocks until complete, captures output)
    │
    └─► For true parallelism: use tmux/screen sessions
        tmux new-session -d -s agent-001 'claude --dangerously-skip-permissions -p "..."'

Parallelism Strategy

# Option 1: Sequential (simple, reliable)
for agent in frontend backend database; do
  claude -p "Act as $agent agent..." --dangerously-skip-permissions
done

# Option 2: Parallel via tmux (complex, faster)
tmux new-session -d -s loki-pool
for i in {1..5}; do
  tmux new-window -t loki-pool -n "agent-$i" \
    "claude --dangerously-skip-permissions -p '$(cat .loki/prompts/agent-$i.md)'"
done

# Option 3: Role switching (recommended)
# Orchestrator maintains agent queue, switches roles per task

Agent Spawning via Task Tool

Primary Method: Claude Task Tool (Recommended)

Use the Task tool to dispatch subagents. Each task gets a fresh context (no pollution).

**Dispatch Implementation Subagent:**
[Task tool call]
- description: "Implement [task name] from plan"
- instructions: |
    1. Read task requirements from .loki/queue/in-progress.json
    2. Implement following TDD (test first, then code)
    3. Verify all tests pass
    4. Commit with conventional commit message
    5. Report: WHAT_WAS_IMPLEMENTED, FILES_CHANGED, TEST_RESULTS
- model: "sonnet" (fast implementation)
- working_directory: [project root]

Parallel Code Review (3 Reviewers Simultaneously)

CRITICAL: Dispatch all 3 reviewers in a SINGLE message with 3 Task tool calls.

[Task tool call 1: code-reviewer]
- description: "Code quality review for [task]"
- instructions: Review for code quality, patterns, maintainability
- model: "opus" (deep analysis)
- context: WHAT_WAS_IMPLEMENTED, BASE_SHA, HEAD_SHA

[Task tool call 2: business-logic-reviewer]  
- description: "Business logic review for [task]"
- instructions: Review for correctness, edge cases, requirements alignment
- model: "opus"
- context: WHAT_WAS_IMPLEMENTED, REQUIREMENTS, BASE_SHA, HEAD_SHA

[Task tool call 3: security-reviewer]
- description: "Security review for [task]"
- instructions: Review for vulnerabilities, auth issues, data exposure
- model: "opus"
- context: WHAT_WAS_IMPLEMENTED, BASE_SHA, HEAD_SHA

Each reviewer returns:

{
  "strengths": ["list of good things"],
  "issues": [
    {"severity": "Critical|High|Medium|Low|Cosmetic", "description": "...", "location": "file:line"}
  ],
  "assessment": "PASS|FAIL"
}

Severity-Based Issue Handling

| Severity | Action | Tracking | |----------|--------|----------| | Critical | BLOCK. Dispatch fix subagent immediately. Re-run ALL 3 reviewers. | None (must fix) | | High | BLOCK. Dispatch fix subagent. Re-run ALL 3 reviewers. | None (must fix) | | Medium | BLOCK. Dispatch fix subagent. Re-run ALL 3 reviewers. | None (must fix) | | Low | PASS. Add TODO comment, commit, continue. | # TODO(review): [issue] - [reviewer], [date], Severity: Low | | Cosmetic | PASS. Add FIXME comment, commit, continue. | # FIXME(nitpick): [issue] - [reviewer], [date], Severity: Cosmetic |

Re-Review Loop

IMPLEMENT → REVIEW (3 parallel) → AGGREGATE
                                      │
              ┌───────────────────────┴───────────────────────┐

              │                                               │
              ▼                                               ▼
    Dispatch fix subagent                              Mark complete
              │                                        Add TODO/FIXME
              ▼                                        Next task
    Re-run ALL 3 reviewers ─────────────────────────────────┘
              │
              └──► Loop until all PASS

Context Pollution Prevention

Each subagent gets fresh context. NEVER:

• Try to fix in orchestrator context (dispatch fix subagent instead)
• Carry state between subagent invocations
• Mix implementation and review in same subagent

Alternative Spawn Methods

Method 2: Sequential Subprocess (for environments without Task tool)

claude --dangerously-skip-permissions \
  -p "$(cat .loki/prompts/eng-backend.md)" \
  --output-format json \
  > .loki/messages/outbox/eng-backend-01/result.json

Method 3: Parallel via tmux (Advanced, for true parallelism)

#!/bin/bash
# Spawn 3 reviewers in parallel
tmux new-session -d -s reviewers
tmux new-window -t reviewers -n code "claude -p '$(cat .loki/prompts/code-reviewer.md)' --dangerously-skip-permissions"
tmux new-window -t reviewers -n business "claude -p '$(cat .loki/prompts/business-reviewer.md)' --dangerously-skip-permissions"
tmux new-window -t reviewers -n security "claude -p '$(cat .loki/prompts/security-reviewer.md)' --dangerously-skip-permissions"
# Wait for all to complete

Model Selection by Task Type

| Task Type | Model | Rationale | |-----------|-------|-----------| | Implementation | sonnet | Fast, good enough for coding | | Code Review | opus | Deep analysis, catches subtle issues | | Security Review | opus | Critical, needs thoroughness | | Business Logic Review | opus | Needs to understand requirements deeply | | Documentation | sonnet | Straightforward writing | | Quick fixes | haiku | Fast iteration |

}

Queue Operations

Claim Task (with file locking):

# Pseudocode - actual implementation uses flock
def claim_task(agent_id, agent_capabilities):
    with file_lock(".loki/state/locks/queue.lock", timeout=10):
        pending = read_json(".loki/queue/pending.json")
        
        # Find eligible task
        for task in sorted(pending.tasks, key=lambda t: -t.priority):
            if task.type not in agent_capabilities:
                continue
            if task.claimedBy and not claim_expired(task):
                continue
            if not all_dependencies_completed(task.dependencies):
                continue
            if circuit_breaker_open(task.type):
                continue
                
            # Claim it
            task.claimedBy = agent_id
            task.claimedAt = now()
            move_task(task, "pending", "in-progress")
            return task
        
        return None

Complete Task:

def complete_task(task_id, result, success=True):
    with file_lock(".loki/state/locks/queue.lock"):
        task = find_task(task_id, "in-progress")
        task.completedAt = now()
        task.result = result
        
        if success:
            move_task(task, "in-progress", "completed")
            reset_circuit_breaker(task.type)
            trigger_dependents(task_id)
        else:
            handle_failure(task)

Failure Handling with Exponential Backoff:

def handle_failure(task):
    task.retries += 1
    task.lastError = get_last_error()
    
    if task.retries >= task.maxRetries:
        # Move to dead letter queue
        move_task(task, "in-progress", "dead-letter")
        increment_circuit_breaker(task.type)
        alert_orchestrator(f"Task {task.id} moved to dead letter queue")
    else:
        # Exponential backoff: 60s, 120s, 240s, ...
        task.backoffSeconds = task.backoffSeconds * (2 ** (task.retries - 1))
        task.availableAt = now() + task.backoffSeconds
        move_task(task, "in-progress", "pending")
        log(f"Task {task.id} retry {task.retries}, backoff {task.backoffSeconds}s")

Dead Letter Queue Handling

Tasks in dead letter queue require manual review:

## Dead Letter Queue Review Process

1. Read `.loki/queue/dead-letter.json`
2. For each task:
   - Analyze `lastError` and failure pattern
   - Determine if:
     a) Task is invalid → delete
     b) Bug in agent → fix agent, retry
     c) External dependency down → wait, retry
     d) Requires human decision → escalate
3. To retry: move task back to pending with reset retries
4. Log decision in `.loki/logs/decisions/dlq-review-{date}.md`

Idempotency

def enqueue_task(task):
    # Generate idempotency key from content
    task.idempotencyKey = hash(json.dumps(task.payload, sort_keys=True))
    
    # Check if already exists
    for queue in ["pending", "in-progress", "completed"]:
        existing = find_by_idempotency_key(task.idempotencyKey, queue)
        if existing:
            log(f"Duplicate task detected: {task.idempotencyKey}")
            return existing.id  # Return existing, don't create duplicate
    
    # Safe to create
    save_task(task, "pending")
    return task.id

Task Cancellation

def cancel_task(task_id, reason):
    with file_lock(".loki/state/locks/queue.lock"):
        for queue in ["pending", "in-progress"]:
            task = find_task(task_id, queue)
            if task:
                task.cancelledAt = now()
                task.cancelReason = reason
                move_task(task, queue, "cancelled")
                
                # Cancel dependent tasks too
                for dep_task in find_tasks_depending_on(task_id):
                    cancel_task(dep_task.id, f"Parent {task_id} cancelled")
                
                return True
        return False

Execution Phases

Phase 0: Bootstrap

1. Create .loki/ directory structure
2. Initialize orchestrator state
3. Validate PRD exists and is readable
4. Spawn initial agent pool (3-5 agents)

Phase 1: Discovery

1. Parse PRD, extract requirements
2. Spawn biz-analytics agent for competitive research
3. Web search competitors, extract features, reviews
4. Identify market gaps and opportunities
5. Generate task backlog with priorities and dependencies

Phase 2: Architecture

1. Spawn eng-backend + eng-frontend architects
2. Select tech stack via consensus (both agents must agree)
3. Self-reflection checkpoint with evidence
4. Generate infrastructure requirements
5. Create project scaffolding

Phase 3: Infrastructure

1. Spawn ops-devops agent
2. Provision cloud resources (see references/deployment.md)
3. Set up CI/CD pipelines

5. Create staging and production environments

Phase 4: Development

1. Decompose into parallelizable tasks
2. For each task:

   a. Dispatch implementation subagent (Task tool, model: sonnet)
   b. Subagent implements with TDD, commits, reports back
   c. Dispatch 3 reviewers IN PARALLEL (single message, 3 Task calls):
      - code-reviewer (opus)
      - business-logic-reviewer (opus)
      - security-reviewer (opus)
   d. Aggregate findings by severity
   e. IF Critical/High/Medium found:
      - Dispatch fix subagent
      - Re-run ALL 3 reviewers
      - Loop until all PASS
   f. Add TODO comments for Low issues
   g. Add FIXME comments for Cosmetic issues
   h. Mark task complete
   

3. Orchestrator monitors progress, scales agents
4. Continuous integration on every commit

Phase 5: Quality Assurance

1. Spawn eng-qa and ops-security agents
2. Execute all quality gates (see Quality Gates section)
3. Bug hunt phase with fuzzing and chaos testing
4. Security audit and penetration testing
5. Performance benchmarking

Phase 6: Deployment

1. Spawn ops-release agent
2. Generate semantic version, changelog
3. Create release branch, tag
4. Deploy to staging, run smoke tests
5. Blue-green deploy to production
6. Monitor for 30min, auto-rollback if errors spike

Phase 7: Business Operations

1. Spawn business swarm agents
2. biz-marketing: Create landing page, SEO, content
3. biz-sales: Set up CRM, outreach templates
4. biz-finance: Configure billing, invoicing
5. biz-support: Create help docs, chatbot
6. biz-legal: Generate ToS, privacy policy

Phase 8: Growth Loop

Continuous cycle:

MONITOR → ANALYZE → OPTIMIZE → DEPLOY → MONITOR
    ↓
Customer feedback → Feature requests → Backlog
    ↓
A/B tests → Winner → Permanent deploy
    ↓
Incidents → RCA → Prevention → Deploy fix

Final Review (After All Development Tasks)

Before any deployment, run comprehensive review:

1. Dispatch 3 reviewers reviewing ENTIRE implementation:
   - code-reviewer: Full codebase quality
   - business-logic-reviewer: All requirements met
   - security-reviewer: Full security audit

2. Aggregate findings across all files
3. Fix Critical/High/Medium issues
4. Re-run all 3 reviewers until all PASS
5. Generate final report in .loki/artifacts/reports/final-review.md
6. Proceed to deployment only after all PASS

Tech Debt Remediation

When backlog exceeds threshold:

thresholds:
  low_issues_max: 20      # Create remediation sprint if exceeded
  cosmetic_issues_max: 50 # Create cleanup task if exceeded
  
actions:
  low: Create task priority 3, assign to original agent type
  cosmetic: Batch into single cleanup task, priority 5

Conflict Resolution

File Contention

When multiple agents might edit the same file:

def acquire_file_lock(file_path, agent_id, timeout=300):
    lock_file = f".loki/state/locks/files/{hash(file_path)}.lock"
    
    while timeout > 0:
        if not os.path.exists(lock_file):
            # Create lock
            with open(lock_file, 'w') as f:
                json.dump({
                    "file": file_path,
                    "agent": agent_id,
                    "acquired": datetime.now().isoformat(),
                    "expires": (datetime.now() + timedelta(minutes=10)).isoformat()
                }, f)
            return True
        
        # Check if lock expired
        lock_data = json.load(open(lock_file))
        if datetime.fromisoformat(lock_data["expires"]) < datetime.now():
            os.remove(lock_file)
            continue
        
        # Wait and retry
        time.sleep(5)
        timeout -= 5
    
    return False  # Failed to acquire

def release_file_lock(file_path):
    lock_file = f".loki/state/locks/files/{hash(file_path)}.lock"
    if os.path.exists(lock_file):
        os.remove(lock_file)

Decision Conflicts

When two agents disagree (e.g., architecture decisions):

## Conflict Resolution Protocol

1. **Detection**: Agent detects conflicting recommendation in messages
2. **Escalate**: Both agents submit reasoning to orchestrator
3. **Evaluate**: Orchestrator compares:
   - Evidence quality (sources, data)
   - Risk assessment
   - Alignment with PRD
   - Simplicity
4. **Decide**: Orchestrator makes final call, documents in LOKI-LOG.md
5. **Notify**: Losing agent receives decision with explanation

Decision logged as:

[TIMESTAMP] CONFLICT RESOLUTION: {topic}

Agents: {agent-1} vs {agent-2} Position 1: {summary} Position 2: {summary} Decision: {chosen position} Reasoning: {why this was chosen} Dissent noted: {key points from rejected position for future reference}

Merge Conflicts (Code)

# When git merge conflict detected:
1. Identify conflicting files
2. For each file:
   a. Parse conflict markers
   b. Analyze both versions
   c. Determine intent of each change
   d. If complementary → merge manually
   e. If contradictory → escalate to orchestrator
3. Run tests after resolution
4. If tests fail → revert, re-queue both tasks with dependency

Anti-Hallucination Protocol

Every agent must:

1. Verify before claiming: Web search official docs
2. Test before committing: Run code, don't assume
3. Cite sources: Log URLs for all external claims
4. Cross-validate: Critical decisions need 2 agent agreement
5. Fail safe: When uncertain, ask orchestrator

Self-Reflection Checkpoints

Triggered at:

• Architecture decisions
• Technology selections
• Major refactors
• Pre-deployment
• Post-incident

Questions (logged in LOKI-LOG.md):

1. What evidence supports this?
2. What would disprove this?
3. What's the worst case?
4. Is there a simpler way?
5. What would an expert challenge?

Timeout and Stuck Agent Handling

Task Timeout Configuration

Different task types have different timeout limits:

# .loki/config/timeouts.yaml
defaults:
  task: 300          # 5 minutes for general tasks

overrides:
  build:
    timeout: 600     # 10 minutes for builds (npm build, webpack, etc.)
    retryIncrease: 1.25  # Increase by 25% on retry
  test:
    timeout: 900     # 15 minutes for test suites
    retryIncrease: 1.5
  deploy:
    timeout: 1800    # 30 minutes for deployments
    retryIncrease: 1.0   # Don't increase
  quick:
    timeout: 60      # 1 minute for simple tasks
    retryIncrease: 1.0

Command Execution with Timeout

All bash commands are wrapped with timeout to prevent stuck processes:

# Standard command execution pattern
run_with_timeout() {
  local timeout_seconds="$1"
  shift
  local cmd="$@"

  # Use timeout command (GNU coreutils)
  if timeout "$timeout_seconds" bash -c "$cmd"; then
    return 0
  else
    local exit_code=$?
    if [ $exit_code -eq 124 ]; then
      echo "TIMEOUT: Command exceeded ${timeout_seconds}s"
      return 124
    fi
    return $exit_code
  fi
}

# Example: npm build with 10 minute timeout
run_with_timeout 600 "npm run build"

Stuck Agent Detection (Heartbeat)

Agents must send heartbeats to indicate they're still alive:

HEARTBEAT_INTERVAL = 60     # Send every 60 seconds
HEARTBEAT_TIMEOUT = 300     # Consider dead after 5 minutes

def check_agent_health(agent_state):
    if not agent_state.get('lastHeartbeat'):
        return 'unknown'

    last_hb = datetime.fromisoformat(agent_state['lastHeartbeat'])
    age = (datetime.utcnow() - last_hb).total_seconds()

    if age > HEARTBEAT_TIMEOUT:
        return 'stuck'
    elif age > HEARTBEAT_INTERVAL * 2:
        return 'unresponsive'
    else:
        return 'healthy'

Stuck Process Recovery

When an agent is detected as stuck:

def handle_stuck_agent(agent_id):
    # 1. Mark agent as failed
    update_agent_status(agent_id, 'failed')

    # 2. Release claimed task back to queue
    task = get_current_task(agent_id)
    if task:
        task['claimedBy'] = None
        task['claimedAt'] = None
        task['lastError'] = f'Agent {agent_id} became unresponsive'
        task['retries'] += 1

        # Increase timeout for retry
        timeout_config = get_timeout_config(task['type'])
        task['timeout'] = int(task['timeout'] * timeout_config.get('retryIncrease', 1.25))

        move_task(task, 'in-progress', 'pending')

    # 3. Increment circuit breaker failure count
    increment_circuit_breaker(agent_role(agent_id))

    # 4. Log incident
    log_incident(f'Agent {agent_id} stuck, task requeued')

Watchdog Pattern

Each subagent implements a watchdog that must be "pet" regularly:

class AgentWatchdog:
    def __init__(self, timeout_seconds):
        self.timeout = timeout_seconds
        self.last_pet = datetime.utcnow()

    def pet(self):
        """Call this during long operations to prevent timeout"""
        self.last_pet = datetime.utcnow()
        self.update_heartbeat()

    def is_expired(self):
        age = (datetime.utcnow() - self.last_pet).total_seconds()
        return age > self.timeout

    def update_heartbeat(self):
        # Write to agent state file
        state_file = f'.loki/state/agents/{self.agent_id}.json'
        with open(state_file, 'r+') as f:
            state = json.load(f)
            state['lastHeartbeat'] = datetime.utcnow().isoformat() + 'Z'
            f.seek(0)
            json.dump(state, f)
            f.truncate()

Graceful Termination

When terminating an agent, use graceful shutdown:

terminate_agent() {
  local pid="$1"
  local grace_period=30  # seconds

  # 1. Send SIGTERM for graceful shutdown
  kill -TERM "$pid" 2>/dev/null || return 0

  # 2. Wait for graceful exit
  for i in $(seq 1 $grace_period); do
    if ! kill -0 "$pid" 2>/dev/null; then
      echo "Agent terminated gracefully"
      return 0
    fi
    sleep 1
  done

  # 3. Force kill if still running
  echo "Force killing agent after ${grace_period}s"
  kill -9 "$pid" 2>/dev/null || true
}

Rate Limit Handling

Distributed State Recovery

Each agent maintains own state in .loki/state/agents/[id].json

Orchestrator Recovery

1. On startup, check .loki/state/orchestrator.json
2. If lastCheckpoint < 60min ago → resume
3. Scan agent states, identify incomplete tasks
4. Re-queue orphaned tasks (claimedAt expired)
5. Reset circuit breakers if cooldown expired
6. Spawn replacement agents for failed ones

Agent Recovery

1. On spawn, check if state file exists for this ID
2. If resuming, continue from last task checkpoint
3. Report recovery event to orchestrator

Exponential Backoff on Rate Limits

def handle_rate_limit():
    base_delay = 60  # seconds
    max_delay = 3600  # 1 hour cap
    
    for attempt in range(10):
        delay = min(base_delay * (2 ** attempt), max_delay)
        jitter = random.uniform(0, delay * 0.1)
        
        checkpoint_state()
        log(f"Rate limited. Waiting {delay + jitter}s (attempt {attempt + 1})")
        sleep(delay + jitter)
        
        if not still_rate_limited():
            return True
    
    # Exceeded retries
    halt_system("Rate limit not clearing after 10 attempts")
    return False

System Operations

Pause/Resume

# Pause system (graceful)
echo '{"command":"pause","reason":"manual pause","timestamp":"'$(date -Iseconds)'"}' \
  > .loki/messages/broadcast/system-pause.json

# Orchestrator handles pause:
# 1. Stop claiming new tasks
# 2. Wait for in-progress tasks to complete (max 30min)
# 3. Checkpoint all state
# 4. Set orchestrator.pausedAt timestamp
# 5. Terminate idle agents

# Resume system
rm .loki/messages/broadcast/system-pause.json
# Orchestrator detects removal, resumes operations

Graceful Shutdown

#!/bin/bash
# .loki/scripts/shutdown.sh

echo "Initiating graceful shutdown..."

# 1. Stop accepting new tasks
touch .loki/state/locks/shutdown.lock

# 2. Wait for in-progress tasks (max 30 min)
TIMEOUT=1800
ELAPSED=0
while [ -s .loki/queue/in-progress.json ] && [ $ELAPSED -lt $TIMEOUT ]; do
  echo "Waiting for $(jq '.tasks | length' .loki/queue/in-progress.json) tasks..."
  sleep 30
  ELAPSED=$((ELAPSED + 30))
done

# 3. Checkpoint everything
cp -r .loki/state .loki/artifacts/backups/shutdown-$(date +%Y%m%d-%H%M%S)

# 4. Update orchestrator state
jq '.phase = "shutdown" | .systemHealth = "offline"' \
  .loki/state/orchestrator.json > tmp && mv tmp .loki/state/orchestrator.json

echo "Shutdown complete"

Backup Strategy

#!/bin/bash
# .loki/scripts/backup-state.sh
# Run hourly via orchestrator or cron

BACKUP_DIR=".loki/artifacts/backups"
TIMESTAMP=$(date +%Y%m%d-%H%M%S)
BACKUP_PATH="$BACKUP_DIR/state-$TIMESTAMP"

mkdir -p "$BACKUP_PATH"

# Backup critical state
cp .loki/state/orchestrator.json "$BACKUP_PATH/"
cp -r .loki/state/agents "$BACKUP_PATH/"
cp -r .loki/queue "$BACKUP_PATH/"
cp .loki/logs/LOKI-LOG.md "$BACKUP_PATH/"

# Compress
tar -czf "$BACKUP_PATH.tar.gz" -C "$BACKUP_DIR" "state-$TIMESTAMP"
rm -rf "$BACKUP_PATH"

# Retain last 24 backups (24 hours if hourly)
ls -t "$BACKUP_DIR"/state-*.tar.gz | tail -n +25 | xargs -r rm

# Update orchestrator
jq --arg ts "$(date -Iseconds)" '.lastBackup = $ts' \
  .loki/state/orchestrator.json > tmp && mv tmp .loki/state/orchestrator.json

echo "Backup complete: $BACKUP_PATH.tar.gz"

Log Rotation

#!/bin/bash
# .loki/scripts/rotate-logs.sh
# Run daily

LOG_DIR=".loki/logs"
ARCHIVE_DIR="$LOG_DIR/archive"
DATE=$(date +%Y%m%d)

mkdir -p "$ARCHIVE_DIR"

# Rotate main log
if [ -f "$LOG_DIR/LOKI-LOG.md" ]; then
  mv "$LOG_DIR/LOKI-LOG.md" "$ARCHIVE_DIR/LOKI-LOG-$DATE.md"
  echo "# Loki Mode Log - $(date +%Y-%m-%d)" > "$LOG_DIR/LOKI-LOG.md"
fi

# Rotate agent logs
for log in "$LOG_DIR/agents"/*.log; do
  [ -f "$log" ] || continue
  AGENT=$(basename "$log" .log)
  mv "$log" "$ARCHIVE_DIR/${AGENT}-${DATE}.log"
done

# Compress archives older than 7 days
find "$ARCHIVE_DIR" -name "*.md" -mtime +7 -exec gzip {} \;
find "$ARCHIVE_DIR" -name "*.log" -mtime +7 -exec gzip {} \;

# Delete archives older than 30 days
find "$ARCHIVE_DIR" -name "*.gz" -mtime +30 -delete

# Update orchestrator
jq --arg ts "$(date -Iseconds)" '.lastLogRotation = $ts' \

Red Flags - Never Do These

Implementation Anti-Patterns

• NEVER skip code review between tasks
• NEVER proceed with unfixed Critical/High/Medium issues
• NEVER dispatch reviewers sequentially (always parallel - 3x faster)
• NEVER dispatch multiple implementation subagents in parallel (conflicts)
• NEVER implement without reading the task requirements first
• NEVER forget to add TODO/FIXME comments for Low/Cosmetic issues
• NEVER try to fix issues in orchestrator context (dispatch fix subagent)

Review Anti-Patterns

• NEVER use sonnet for reviews (always opus for deep analysis)
• NEVER aggregate before all 3 reviewers complete
• NEVER skip re-review after fixes
• NEVER mark task complete with Critical/High/Medium issues open

System Anti-Patterns

• NEVER delete .loki/state/ directory while running
• NEVER manually edit queue files without file locking
• NEVER skip checkpoints before major operations
• NEVER ignore circuit breaker states
• NEVER deploy without final review passing

Always Do These

• ALWAYS launch all 3 reviewers in single message (3 Task calls)
• ALWAYS specify model: "opus" for each reviewer
• ALWAYS wait for all reviewers before aggregating
• ALWAYS fix Critical/High/Medium immediately
• ALWAYS re-run ALL 3 reviewers after fixes (not just the one that found issue)
• ALWAYS checkpoint state before spawning subagents
• ALWAYS log decisions with evidence in LOKI-LOG.md

If Subagent Fails

1. Do NOT try to fix manually (context pollution)
2. Dispatch fix subagent with specific error context
3. If fix subagent fails 3x, move to dead letter queue
4. Open circuit breaker for that agent type
5. Alert orchestrator for human review

Exit Conditions

| Condition | Action | |-----------|--------| | Product launched, stable 24h | Enter growth loop mode | | Unrecoverable failure | Save state, halt, request human | | PRD updated | Diff, create delta tasks, continue | | Revenue target hit | Log success, continue optimization | | Runway < 30 days | Alert, optimize costs aggressively |
