Claude Flow Novice - Advanced orchestration platform for multi-agent AI workflows with CFN Loop architecture Includes Local RuVector Accelerator and all CFN skills for complete functionality.

# Skills System Documentation

**Version:** 2.18.1
**Status:** Production

## Overview

Modular, reusable agent capabilities with explicit coordination interfaces and semantic codebase search.

## New: RuVector Codebase Search

**Location:** `.claude/skills/cfn-ruvector-codebase-index/`
**Purpose:** Semantic search via OpenAI embeddings

```bash
# Full index
./.claude/skills/cfn-ruvector-codebase-index/index.sh --full

# Search
./.claude/skills/cfn-ruvector-codebase-index/search.sh "query" --top 5

# Incremental (git changes)
/cfn-ruvector:codebase-reindex
```

**Components:**
- `index.sh` - Indexing entry point
- `search.sh` - Query interface
- `indexer.js` - Batch processor
- `embeddings.js` - OpenAI API calls
- `search.js` - Vector similarity
- `.cfn-manifest.json` - CFN vs custom file tracking

**Manifest System:**
- `cfn_files`: Overwritten on CFN update
- `protected_files`: Never touched (config, data)
- Unlisted files: Custom, preserved

**Requirements:** `OPENAI_API_KEY` or `ZAI_API_KEY`

## Core Principles

1. **Maximum Modularity**: Each skill is independently maintainable
2. **Explicit Interfaces**: All dependencies declared in SKILL.md
3. **Minimal Coupling**: No hidden dependencies between skills
4. **Comprehensive Testing**: Each skill includes test suite

### Agent Spawning
**Location:** `.claude/skills/agent-spawning/`
**Purpose:** Manage agent lifecycle and dependencies

**Key Features:**

**Skill Access:**
CLI-spawned agents inherit project working directory, providing identical skill access to Main Chat:

```bash
# Agent discovery (filesystem scanning)
find .claude/skills -name "*.sh" -type f

# Direct skill invocation
./.claude/skills/redis-coordination/invoke-waiting-mode.sh

# Post-edit hook integration
./.claude/hooks/invoke-post-edit.sh file.ts --agent-id "agent-1"
```

**Validation:**
Post-edit pipeline demonstrates skill access:
- Security scanner: `.claude/skills/hook-pipeline/security-scanner.sh`
- Hook invocation from CLI agents
- Logs: `.artifacts/logs/post-edit-pipeline.log`

**Testing:**
```bash
./.claude/skills/agent-spawning/test-spawn.sh
```

- `orchestrate-cfn-loop.sh` (lines 1246-1266): Product Owner decision parsing

**Pattern Reuse:** 95% code reuse between Loop 3 and Loop 2 implementations

**Eliminated Issues:**
- BUG #10: Race conditions (polling wait for :result key)
- BUG #11: Template enforcement failure (agents can't be forced to use bash tools)

**Testing:**
```bash
# Unit tests (skill-level)
./.claude/skills/loop3-output-processing/test-loop3-processing.sh
./.claude/skills/loop2-output-processing/test-loop2-processing.sh

# Integration test (orchestrator-level)

  --mode "mvp" \
  --loop3-agents "coder" \
  --loop2-agents "reviewer,tester" \
  --product-owner "product-owner" \
  --max-iterations 1
```

**Performance Metrics:**
- Parallel speedup: 3x for 3 agents (max latency vs sum of sequential latencies)

### Best Practices

1. **Single Responsibility**: Each skill should do one thing well
2. **Explicit Dependencies**: Declare all Redis keys, scripts, and skills used
3. **Idempotent Operations**: Scripts should be safe to run multiple times
4. **Error Handling**: Always validate inputs and handle failures gracefully
5. **Comprehensive Tests**: Cover happy path, edge cases, and error conditions
6. **Documentation**: Keep SKILL.md synchronized with implementation

### Testing Guidelines

**Test Coverage Requirements:**
- ✅ Happy path (expected inputs, expected outputs)
- ✅ Edge cases (boundary values, empty inputs)
- ✅ Error handling (invalid inputs, missing dependencies)
- ✅ Timeout behavior (blocking operations, long-running tasks)
- ✅ Concurrent execution (race conditions, resource conflicts)

**Example Test Structure:**
```bash
#!/bin/bash
# test-my-skill.sh

test_happy_path() {
  result=$(./main-script.sh --input "valid")
  [[ "$result" == "expected" ]] && echo "✅ PASS" || echo "❌ FAIL"
}

test_error_handling() {
  result=$(./main-script.sh --input "invalid" 2>&1)
  [[ "$result" =~ "Error:" ]] && echo "✅ PASS" || echo "❌ FAIL"
}

# Run all tests
test_happy_path
test_error_handling
```

## Skill Coordination Patterns

### Simple Chain
```bash
# Agent A completes → Agent B starts
redis-cli lpush "swarm:task123:agentA:done" "complete"
redis-cli blpop "swarm:task123:agentA:done" 0  # Agent B waits here
```

### Hierarchical Broadcast
```bash
# Coordinator → All agents
for agent in "${agents[@]}"; do
  redis-cli lpush "swarm:task123:${agent}:wake" "start"
done
```

### Mesh Hybrid
```bash
# Agent A → Agents B, C, D (parallel)
redis-cli lpush "swarm:task123:agentB:wake" "start"
redis-cli lpush "swarm:task123:agentC:wake" "start"
redis-cli lpush "swarm:task123:agentD:wake" "start"

# Agent B, C, D → Agent E (convergence)
redis-cli lpush "swarm:task123:agentB:done" "complete"
redis-cli lpush "swarm:task123:agentC:done" "complete"
redis-cli lpush "swarm:task123:agentD:done" "complete"

# Agent E waits for all three
for agent in B C D; do
  redis-cli blpop "swarm:task123:agent${agent}:done" 0
done
```

## Skill Lifecycle

### Development Phase
1. Create skill directory structure
2. Write SKILL.md specification
3. Implement primary scripts
4. Add comprehensive tests
5. Document examples

### Review Phase
1. Functional validation (does it work?)
2. Interface validation (is it easy to use?)
3. Test coverage validation (is it well-tested?)
4. Documentation validation (is it clear?)

### Production Phase
1. Deploy to `.claude/skills/`
2. Update CLAUDE.md with skill reference
3. Monitor usage and performance
4. Collect feedback for improvements

### Maintenance Phase
1. Monthly functional review
2. Quarterly performance audit
3. Annual architecture assessment
4. Deprecation planning (if needed)

## Skill Versioning

**Semantic Versioning:**
- **Major (X.0.0)**: Breaking interface changes
- **Minor (0.X.0)**: New features, backward compatible
- **Patch (0.0.X)**: Bug fixes, no interface changes

**Version Declaration:**
```json
{
  "skill": "redis-coordination",
  "version": "2.1.0",
  "compatibleWith": ["2.0.0", "2.1.0"],
  "deprecates": ["1.x.x"]
}
```

## Skill Dependencies

### Hard Dependencies
Required for skill to function. Declared in SKILL.md.

Example:
```markdown
## Dependencies
- redis-coordination (>= 2.0.0)
- agent-spawning (>= 1.5.0)
```

### Soft Dependencies
Optional enhancements. Skill degrades gracefully if missing.

Example:
```markdown
## Optional Dependencies
- transparency-middleware (audit logging)
- event-bus (event streaming)
```

## Migration from v1

**v1 Pattern (Implicit Coordination):**
```javascript
// Main chat spawns agents, expects implicit coordination
Task("coder", "Implement feature")
Task("reviewer", "Review implementation")
// ❌ No explicit dependency management
```

**v2 Pattern (Skills-Based Coordination):**
```bash
# Use Redis coordination skill
./.claude/skills/redis-coordination/orchestrate-cfn-loop.sh \
  --task-id "unique-id" \
  --loop3-agents "coder" \
  --loop2-agents "reviewer"
# ✅ Explicit dependencies via Redis BLPOP
```

- Wake-up latency: <100ms (p95)
- Token savings: 100% while waiting
- Scalability: 10+ agents, indefinite iterations
- Test coverage: 8/8 passing (100%)
- Retry success rate: 85% recovery from transient failures
- Quorum completion: 6/7 agents minimum (configurable)
- Heartbeat overhead: <5ms per check
- Metrics export: All 4 formats validated (JSON, Prometheus, CSV, OTLP)

**Agent Spawning Skill:**

- Cost savings (CLI): 95-98% vs Task tool

**CFN Loop Validation Skill:**

## Troubleshooting

### Skill Not Found
```bash
# Verify skill exists
ls .claude/skills/my-skill/

# Check SKILL.md is present
cat .claude/skills/my-skill/SKILL.md
```

### Dependency Missing
```bash
# Check Redis connection
redis-cli ping

# Verify required skills installed
ls .claude/skills/redis-coordination/
```

### Test Failures
```bash
# Run tests with verbose output
bash -x ./.claude/skills/my-skill/test-my-skill.sh

# Check Redis state
redis-cli keys "swarm:*"
```

### Agent Timeout
```bash
# Check if agent entered waiting mode
redis-cli get "swarm:task123:agent1:waiting"

# Manually wake agent
redis-cli lpush "swarm:task123:agent1:wake" "manual-wake"
```

## Future Enhancements

**Planned Skills (v2.1):**
