Quick Start

1. Select Agents for a Task

# Recommended: Use fallback-enabled selection
./.claude/skills/agent-lifecycle/cli/select-agents.sh "Implement JWT authentication"

# Output (JSON):
# {
#   "loop3": ["backend-developer", "security-specialist"],
#   "loop2": ["code-reviewer", "tester", "security-specialist"],
#   "product_owner": "product-owner",
#   "category": "backend-api",
#   "confidence": 0.92
# }

2. Spawn Agents

./.claude/skills/agent-lifecycle/cli/spawn-agent.sh \
  --task "Implement user authentication" \
  --agents coder,security-specialist,tester \
  --agent-id coordinator-1

3. Track Lifecycle Events

# Register agent spawn
./.claude/skills/agent-lifecycle/cli/lifecycle-hook.sh spawn \
  --agent-id "${AGENT_ID}" \
  --agent-type "${AGENT_TYPE}" \
  --acl-level 1

# Update confidence
./.claude/skills/agent-lifecycle/cli/lifecycle-hook.sh update \
  --agent-id "${AGENT_ID}" \
  --confidence 0.85

# Mark completion
./.claude/skills/agent-lifecycle/cli/lifecycle-hook.sh complete \
  --agent-id "${AGENT_ID}" \
  --confidence 0.90

Module Details

Selection Module (lib/selection/)

Note: Task classification (type/domain) and complexity/iteration estimation now live in cfn-task-planning (.claude/skills/cfn-task-planning/SKILL.md), which absorbed the deprecated cfn-task-intelligence. This module consumes that classification to select and spawn agents. Use cfn-task-planning to classify; do not duplicate task classification here.

Purpose: Agent selection from a task classification (selection, not re-classification)

Features:

• Task classification into 9 categories
• Agent selection for Loop 3 (implementers) and Loop 2 (validators)
• Guaranteed non-empty agent arrays (fallback behavior)
• Agent validation against available profiles
• TypeScript implementation for type safety

Task Categories:

Spawning Module (lib/spawning/)

Purpose: Agent deployment and dependency management

Features:

• System dependency validation (Bash 4.0+, Node.js, etc.)
• Node.js module validation (redis, dotenv)
• Claude Flow prerequisites check
• Multi-agent spawning
• Provider routing support

Performance Targets:

• Dependency check: <50ms
• Spawn time: <200ms
• Stop time: <150ms
• Success rate: 99.5%

Output Module (lib/output/)

Purpose: Structured output extraction from agents

Features:

• Multi-pattern parsing with fallbacks
• Output validation framework
• Redis coordination integration
• Universal pattern system for any agent type

Audit Module (lib/audit/)

Purpose: SQLite lifecycle tracking

Features:

• Agent spawn registration
• Confidence updates during work
• Completion tracking
• Cross-session recovery support
• ACL level enforcement (1-6)

---

Integration with CFN Loop

# 1. Classify task and select agents
CLASSIFICATION=$(./lib/selection/task-classifier.sh "$TASK_DESCRIPTION")
AGENTS_JSON=$(./cli/select-agents.sh "$TASK_DESCRIPTION")

# 2. Extract agent lists
LOOP3_AGENTS=$(echo "$AGENTS_JSON" | jq -r '.loop3 | join(",")')
LOOP2_AGENTS=$(echo "$AGENTS_JSON" | jq -r '.loop2 | join(",")')

# 3. Spawn agents with lifecycle tracking
./cli/lifecycle-hook.sh spawn --agent-id "$AGENT_ID" --agent-type "$AGENT_TYPE"
./cli/spawn-agent.sh --task "$TASK" --agents "$LOOP3_AGENTS" --agent-id "$AGENT_ID"

# 4. After completion
./cli/lifecycle-hook.sh complete --agent-id "$AGENT_ID" --confidence 0.92

Migration from Individual Skills

Old Paths → New Paths

CLI Wrappers (Convenience)

For easier migration, use CLI wrappers:

./.claude/skills/agent-lifecycle/cli/select-agents.sh  # Recommended entry point
./.claude/skills/agent-lifecycle/cli/spawn-agent.sh
./.claude/skills/agent-lifecycle/cli/lifecycle-hook.sh

---

TypeScript Implementation

The selection module includes a production-ready TypeScript implementation:

# Use TypeScript version
export USE_TYPESCRIPT=true
./lib/selection/select-agents-with-fallback.sh "Implement auth"

# Or call directly
node ./lib/selection/dist/cli.cjs "Implement auth"

Benefits:

• Type-safe interfaces
• 95.2% classification accuracy
• 42 tests, 100% passing
• Path traversal security validation

---

Dependencies

• Bash: 4.0+
• Node.js: LTS (for TypeScript features)
• jq: JSON processing
• SQLite3: Audit database
• Redis: Coordination (optional)

---

Testing

# Test selection
./lib/selection/src/agent-selector.test.ts

# Test spawning dependencies
./lib/spawning/check-dependencies.sh

# Test lifecycle hooks
./lib/audit/simple-audit.sh
