| name | subagent-prompt-construction |
| description | Systematic methodology for constructing compact (<150 lines), expressive, Claude Code-integrated subagent prompts using lambda contracts and symbolic logic. Use when creating new specialized subagents for Claude Code with agent composition, MCP tool integration, or skill references. Validated with phase-planner-executor (V_instance=0.895). |

Spec
λ(use_case, complexity) → subagent_prompt |
∧ require(need_orchestration(use_case) ∨ need_mcp_integration(use_case))
∧ complexity ∈ {simple, moderate, complex}
∧ line_target = {simple: 30-60, moderate: 60-120, complex: 120-150}
∧ template = read(templates/subagent-template.md)
∧ patterns = read(reference/patterns.md)
∧ integration = read(reference/integration-patterns.md)
∧ apply(template, use_case, patterns, integration) → draft
∧ validate(|draft| ≤ 150 ∧ integration_score ≥ 0.50 ∧ clarity ≥ 0.80)

∧ output = {prompt: draft, metrics: validation_report}
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%
