Artifacts:

• templates/: Reusable subagent template (lambda contract structure)
• examples/: Compact validated examples (≤150 lines each)
• reference/patterns.md: Core patterns (orchestration, analysis, enhancement)
• reference/integration-patterns.md: Claude Code feature integration (agents, MCP, skills)
• reference/symbolic-language.md: Formal syntax reference (logic operators, quantifiers)
• reference/case-studies/: Detailed analysis and design rationale
• scripts/: Automation tools (validation, metrics, pattern extraction)

Usage: See templates/subagent-template.md for structure. Apply integration patterns for Claude Code features. Validate compactness (≤150 lines), integration (≥1 feature), clarity. Reference examples/ for compact demonstrations and case-studies/ for detailed analysis.

Constraints: Max 150 lines per prompt | Use symbolic logic for compactness | Explicit dependencies section | Integration score ≥0.50 | Test coverage ≥80% for generated artifacts

Validation: V_instance=0.895 (phase-planner-executor: 92 lines, 2 agents, 2 MCP tools) | V_meta=0.709 (compactness=0.65, integration=0.857, maintainability=0.85) | Transferability=95%
