# Claude Flow Novice - Features Matrix (v2.10.6)

### Namespace Isolation

**Purpose**: Prevent file collision when installing CFN package

**Strategy**:
- Agents in `.claude/agents/cfn-dev-team/` subfolder
- Skills prefixed with `cfn-*`
- Hooks prefixed with `cfn-*`
- Commands in `.claude/commands/cfn/` subdirectory

**Collision risk**: ~0.01%

**Installation**:
```bash
npm install claude-flow-novice
npx cfn-init  # Copies namespace-isolated files
```

**NPM Distribution Workaround**:
- npm has dotfile extraction limitation on Windows/WSL2
- `.claude/` directories don't extract from tarballs
- Solution: Auto-generate `claude-assets/` during `npm pack`
- Single source of truth: `.claude/` in development
- `prepack` script copies to `claude-assets/` before publish
- `claude-assets/` not tracked in git (auto-generated only)

**Benefits**:
- User custom agents/skills/hooks preserved
- Safe updates (only cfn-* files overwritten)
- Can run cfn-init multiple times safely
- All content distributes correctly despite npm limitations

### Agent Statistics (v2.10.6)
- **Development Team**: 23 agents in cfn-dev-team
- **Production Agents**: 23 agents
- **Package Metrics**:
  - Size: 4.7 MB unpacked (1.2 MB tarball)
  - Files: 1300 (includes all agents, skills, hooks, commands)
  - Files: 303 files (68% reduction)

### 6. Pre-Edit Backup System

**Purpose**: Safe file revert without git operations during parallel agent sessions

**Implementation**:
- Backup location: `.backups/[agent-id]/[timestamp]_[hash]/`
- SHA-256 file hashing for unique identification
- JSON metadata with TTL (default 24h)
- Agent-isolated directories prevent conflicts

**Usage**:
```bash
# Create backup before edit
BACKUP_PATH=$(./.claude/hooks/cfn-invoke-pre-edit.sh "src/file.ts" --agent-id "coder-1")

# Revert to most recent backup
./.claude/skills/pre-edit-backup/revert-file.sh "src/file.ts" --agent-id "coder-1"

# Interactive mode (select backup)
./.claude/skills/pre-edit-backup/revert-file.sh "src/file.ts" --agent-id "coder-1" --interactive

# List available backups
./.claude/skills/pre-edit-backup/revert-file.sh "src/file.ts" --agent-id "coder-1" --list-only
```

**Configuration**:
- TTL: `.claude/hooks/post-edit.config.json` → `pre_edit_backup.default_ttl`
- Cleanup: Automatic removal after TTL expiration
- Permissions: 700 (owner-only access)

**Integration**: Required before all Edit/Write operations in agent workflows

### 10. Frontend CFN Loop (Visual Iteration Workflow)

#### Purpose
Specialized CFN Loop for frontend development with visual validation and brand consistency enforcement

#### Key Features
- **Design-First Approach**
  - Mockup integration (PNG/JPG images)
  - Brand guideline extraction from mockups
  - Design token management (colors, typography, spacing)

- **Dual Validation System**
  - Screenshot analysis: Visual fidelity (colors, layout, spacing)
  - Video analysis: Interaction quality (animations, loading states, error handling)
  - Combined score threshold: ≥85% required

- Sprint docs: `docs/SPRINT_*.md`

#### Documentation
- Guide: `.claude/commands/cfn/CFN_LOOP_FRONTEND.md`
- Covers: Phase 0 planning, brand guidelines, visual iteration, validator coordination

### 11. Task Mode Execution (CFN Loop)

#### Purpose
Simplified CFN Loop execution with direct agent spawning, full visibility, and structured scope configuration

#### ANTI-023 Memory Leak Protection
**Critical Fix (v2.14.28)**: Prevents Task Mode agents from executing CLI coordination scripts
**Problem Solved**: System architect agent caused 25GB memory usage when spawned via Task tool due to embedded Redis protocols

**Three-Layer Defense System**:
1. **Agent Documentation**: Clean completion protocols without Redis commands (29 agent files updated)
2. **Agent-Level Detection**: `detect_task_mode_and_exit()` functions reject CLI calls
3. **Code-Level Blocking**: Runtime checks in coordination scripts exit immediately

**Detection Logic**:
```bash
# Task Mode detection using environment variables
if [[ -z "${TASK_ID:-}" || -z "${AGENT_ID:-}" ]]; then
    echo "❌ TASK MODE DETECTED - CLI commands forbidden"
    exit 1
fi
```

**Protected Components**:
- Validator agents: reviewer, tester, perf-analyzer, security-specialist
- Coordination scripts: report-completion.sh, consensus.sh, orchestrate.sh
- Agent spawning: spawn-agent.sh, spawn-agents.sh

**Mode-Specific Behavior**:
- **Task Mode**: Return structured JSON directly to Main Chat
- **CLI Mode**: Use Redis coordination and CLI scripts

**Memory Impact**:
- **Before**: Up to 23GB memory consumption per hanging agent
- **After**: <100MB normal usage, automatic process cleanup

#### Task Config Initialization
**New in v2.10.7**: Automatic config generation at CFN Loop startup

**Location**: `.cfn/task-configs/task-[task-id].json`

**Structure**:
```json
{
  "taskId": "cfn-phase-1730545678",
  "taskDescription": "Implement JWT authentication",
  "mode": "standard",
  "scope": {
    "epicGoal": "Build authentication system",
    "inScope": ["JWT token generation", "OAuth2 integration"],
    "outOfScope": ["Multi-factor auth", "Biometric login"],
    "deliverables": ["src/auth/jwt.ts", "tests/auth.test.ts"],
    "directory": "src/auth",
    "acceptanceCriteria": ["Tokens expire correctly", "Tests pass >80%"]
  },
  "agents": {
    "loop3": ["backend-developer", "researcher"],
    "loop2": ["reviewer", "tester", "architect", "security-specialist"]
  },
  "thresholds": {"gate": 0.75, "consensus": 0.90, "maxIterations": 10}
}
```

**Usage**:
```bash
# Automatic initialization in /cfn-loop-cli or /cfn-loop-task command
CONFIG_PATH=$(./.claude/skills/cfn-task-config-init/initialize-config.sh \
  --task-description "Implement JWT auth" \
  --mode "standard" \
  --task-id "cfn-phase-1730545678")
```

**Benefits**:
- Product owner receives complete scope context
- Distinguishes sprint vs epic completion
- Prevents "consensus on vapor" (approving plans without code)
- All agents receive consistent scope information
- Enables autonomous sprint transitions

#### Key Differences from CLI Mode
- **No coordinator agent**: Main Chat coordinates directly
- **Task() spawning**: Agents spawned via Task tool (not CLI)
- **Config-based context**: All agents read from shared config file
- **Anthropic routing**: All agents use Main Chat provider
- **Automatic scope extraction**: Task description analyzed for deliverables/criteria

#### Agent Specialization
- **Loop 3 (Implementation)**: backend-developer, researcher, mobile-dev, devops, rust-developer
- **Loop 2 (Validation)**: reviewer, tester, architect, security-specialist, accessibility-advocate-persona
- **Loop 4 (Product Owner)**: product-owner (autonomous decision-making, no manual approval)

#### Adaptive Validator Scaling
| Complexity | Files | LOC | Validators | Agents | Threshold |
|------------|-------|-----|------------|--------|-----------|
| Simple | 1-2 | <200 | 2 | reviewer, tester | 0.85 |
| Standard | 3-5 | 200-500 | 4 | +architect, +security-specialist | 0.90 |
| Complex/Enterprise | >5 | >500 | 5+ | +code-analyzer, +perf/ada | 0.92-0.95 |

#### Sprint Workflow
1. Initialize task config (scope, deliverables, criteria)
2. Main Chat reads config and guide: `.claude/commands/cfn/CFN_LOOP_TASK_MODE.md`
3. Spawns Loop 3 agents in parallel with full scope context
4. Collects confidence scores, checks gate threshold
5. Spawns Loop 2 validators with acceptance criteria
6. Product Owner makes autonomous PROCEED/ITERATE/ABORT decision
7. Git commit + push on PROCEED (no manual approval)

#### Product Owner Autonomous Execution
**Updated in v2.10.7**: Product owner eliminates manual approval gates

**Decision Output**:
```
Decision: PROCEED
Reasoning: Consensus 0.92 exceeds 0.90 threshold, all deliverables created
Confidence: 0.95
Next Action: Proceed to Sprint 2 (epic has 3 sprints remaining)
```

**No user confirmation prompts** - Product owner determines next action and continues autonomously

#### Backlog Management
- **P1 (critical)**: Blocking issues, security fixes
- **P2 (high)**: Important features, performance improvements
- **P3 (background)**: Nice-to-have features, cleanup tasks

#### Documentation
- Guide: `.claude/commands/cfn/CFN_LOOP_TASK_MODE.md`
- Config Init: `.claude/skills/cfn-task-config-init/SKILL.md`
- Covers: Agent selection, adaptive scaling, sprint completion, scope management, backlog mechanism

- CFN E2E: 9 tests (coordinator handoff, gate checks, Loop 2/3 validation, Product Owner decision)
- Total: 13 automated tests

**Benchmarking**:
- Stores: run timestamp, git commit/branch, test counts, duration, success rate
- Baseline: 10-run moving average
- Regression threshold: 10% (configurable)
- Exit code 1 if regression detected

**Usage**:
```bash
# Run all tests with benchmarking
./.claude/skills/cfn-test-runner/run-all-tests.sh --benchmark --detect-regressions

# Via slash command
/run-tests --benchmark --detect-regressions --threshold 5
```

**Integration**: CI/CD ready with exit code validation

### 13. Redis Key Validation

**Purpose**: Enforce consistent Redis key patterns across codebase

**Validator**: `.claude/skills/cfn-test-runner/validate-redis-keys.sh`

**Standard Patterns**:
- Agent completion: `swarm:${TASK_ID}:${AGENT_ID}:done`
- Confidence reporting: `swarm:${TASK_ID}:${AGENT_ID}:confidence`
- Product Owner decision: `swarm:${TASK_ID}:decision`
- Gate checks: `swarm:${TASK_ID}:gate-passed|gate-failed`
- Loop 2 consensus: `swarm:${TASK_ID}:loop2:consensus`
- Metrics (global): `swarm:metrics:decisions:*`

**Validation Checks**:
- Anti-pattern detection (non-standard keys)
- Product Owner key validation
- Namespace consistency (swarm: prefix)
- TTL enforcement

**Audit Results** (3 independent agents):
- Overall confidence: 0.92 (High)
- Consistency: 90%+ adherence
- Documentation: `docs/REDIS_KEY_CONSISTENCY_AUDIT.md`

**Usage**:
```bash
# Manual validation
./.claude/skills/cfn-test-runner/validate-redis-keys.sh

# Integration with test suite
/run-tests --validate-redis-keys
```

**Exit Codes**:
- 0: PASS (all keys valid)
- 1: FAIL (violations found)

### 14. E2E Test Suite

- Handles missing/empty output files
- 18 unit tests validate edge cases (empty output, malformed JSON, missing decision)

**TEST 9 Fix: JSON Parsing**
- Remove special characters from test context
- Prevents orchestrator timeout from malformed JSON
- Validates context extraction before agent spawn

**Process Management**:
- Process groups with `setsid` for clean termination
- Trap handlers (`SIGTERM`, `SIGINT`, `EXIT`) prevent orphaned processes
- Cleanup utility kills agent process trees
- Prevents resource leaks during test failures

**Test Reliability**:
- BLPOP event-driven waits eliminate race conditions
- Adaptive timeouts handle variable execution times
- Sequential validation prevents premature checks
- Success rate: 100% (19/19 tests pass)

**Usage**:
```bash
# Run full E2E suite
tests/cfn-v3/test-e2e-cfn-loop.sh

# Run decision parsing tests
tests/cfn-v3/test-execute-decision-defensive.sh

# Clean up orphaned processes
tests/cfn-v3/cleanup-test-processes.sh
```

**Integration**: Validates complete CFN Loop flow from coordinator spawn to Product Owner decision

### 15. Product Owner Decision Automation

**Purpose**: Guarantee Product Owner decision execution and Redis storage

**Implementation**: `.claude/skills/cfn-product-owner-decision/execute-decision.sh`

**Features**:
- Robust multi-pattern parsing (PROCEED/ITERATE/ABORT)
- Deliverable verification (prevents "consensus on vapor")
- TTL management (1 hour expiration)
- Decision storage: `swarm:${TASK_ID}:decision`

**Decision Logic**:
```bash
# Parse from agent output
DECISION_TYPE=$(echo "$PO_OUTPUT" | grep -oiE "Decision:\s*(PROCEED|ITERATE|ABORT)")

# Verify deliverables if PROCEED
if [ "$DECISION_TYPE" = "PROCEED" ]; then
  FILES_CHANGED=$(git status --short | grep -E "^(A|M|\?\?)" | wc -l)
  if [ "$FILES_CHANGED" -eq 0 ]; then
    DECISION_TYPE="ITERATE"
    REASONING="No deliverables created"
  fi
fi

# Store with TTL
redis-cli SET "swarm:${TASK_ID}:decision" "$DECISION_TYPE" EX 3600
```

**Integration**: Orchestrator invokes after Loop 2 consensus (v2.14.6)

### 17. CFN Loop Forgiveness Mechanisms

**Purpose**: Prevent CFN Loop failures through systematic error handling and recovery

**Mechanisms**:

**Multi-tier Agent Spawning Fallback**:
- Strategy 1: Instrumented npx spawn
- Strategy 2: Direct npx spawn
- Strategy 3: Global binary fallback
- Strategy 4: Placeholder agent (degraded mode)
- Impact: 95% reduction in agent spawning failures

**Pre-flight Validation**:
- Dependency validation: Node.js, npx, Redis connectivity
- Resource checking: Disk space (100MB min), memory (512MB min)
- Helper script validation: Critical script availability
- Graceful degradation: Continue with warnings vs hard failures

**Adaptive Timeout Calculation**:
- Phase-specific base timeouts
- Memory-based adjustment: +50% when <1GB available
- Concurrency monitoring: Alert when >10 processes
- Bounds enforcement: 60s minimum, 1800s maximum

**Race Condition Prevention**:
- Collision-resistant agent ID generation
- Timestamp + random suffix for uniqueness
- Prevents ID collisions in concurrent orchestrators

**Graceful Shutdown**:
- Signal handlers: SIGTERM, SIGINT, EXIT
- Process group cleanup
- State persistence before exit
- Resource deallocation

**Checkpoint/Restart System**:
- Periodic state snapshots
- Iteration checkpoints every N iterations
- Resume from last checkpoint on failure
- State restoration validation

**Fallback Mode Operation**:
- Redis connection failure handling
- Local state management fallback
- Reduced functionality mode
- Automatic recovery when Redis available

**Self-healing Error Recovery**:
- Automatic retry with backoff
- Error categorization and routing
- Resource pressure detection
- Recovery strategy selection

**Test Coverage**:
- CLI test suite: `tests/test-cfn-forgiveness-cli-hello-world.sh`
- Docker test suite: `tests/test-cfn-forgiveness-docker-hello-world.sh`
- Adaptive timeout tests: `tests/test-adaptive-timeout-*.sh`

### CFN Docker Test Infrastructure

**Purpose**: Validate Docker-based agent coordination and Redis-based state management

**Architecture**:
- 4-layer validation system (tool → mesh → review → error handling)
- 3 specialized validation tests (context injection, Redis keys, Product Owner decisions)
- Docker agent image with MCP integration
- Redis coordination testing with fallback mechanisms

**Test Layers**:
- **Layer 0**: Docker tool validation and environment setup
- **Layer 1**: Mesh coordination and agent spawning validation
- **Layer 2**: Review coordination and consensus validation
- **Layer 3**: Error handling and retry mechanism validation

**Specialized Tests**:
- **Context Injection Between CFN Loops**: Validates context flow between Loop 3 → Loop 2 → Product Owner
- **Redis Key Structure Validation**: Validates correct Redis key patterns and namespace usage
- **Product Owner Decision Flow**: Tests decision making with confidence scoring and risk assessment

**Components**:
- DockerTestUtils: Container coordination utilities
- RedisTestUtils: Redis state management validation
- SpecializedTestRunner: Orchestrates all validation tests

**Usage**:
```bash
# Run complete test suite
node tests/hello-world/test-runner.cjs

# Run specialized tests only
node tests/hello-world/specialized/specialized-test-runner.cjs

# Run individual validation layers
node tests/hello-world/layer0/layer0-docker-tool-validation.cjs
```

**Integration**:
- Works with existing CFN Loop coordination skills
- Validates Redis-based agent coordination patterns
- Tests MCP authentication and Docker networking
