# Subagent Prompt Construction Skill
|
||
|
||
**Status**: ✅ Validated (V_meta=0.709, V_instance=0.895)
|
||
**Version**: 1.0
|
||
**Transferability**: 95%+
|
||
|
||
---
|
||
|
||
## Overview
|
||
|
||
Systematic methodology for constructing compact (<150 lines), expressive, Claude Code-integrated subagent prompts using lambda contracts and symbolic logic. Validated with phase-planner-executor subagent achieving V_instance=0.895.
|
||
|
||
---
|
||
|
||
## Quick Start
|
||
|
||
1. **Choose pattern**: See `reference/patterns.md`
|
||
- Orchestration: Coordinate multiple agents
|
||
- Analysis: Query and analyze data via MCP
|
||
- Enhancement: Apply skills to improve artifacts
|
||
- Validation: Check compliance
|
||
|
||
2. **Copy template**: `templates/subagent-template.md`
|
||
|
||
3. **Apply integration patterns**: `reference/integration-patterns.md`
|
||
- Agent composition: `agent(type, desc) → output`
|
||
- MCP tools: `mcp::tool_name(params) → data`
|
||
- Skill reference: `skill(name) → guidelines`
|
||
|
||
4. **Use symbolic logic**: `reference/symbolic-language.md`
|
||
- Operators: `∧`, `∨`, `¬`, `→`
|
||
- Quantifiers: `∀`, `∃`
|
||
- Comparisons: `≤`, `≥`, `=`
|
||
|
||
5. **Validate**: Run `scripts/validate-skill.sh`

## Three-Layer Architecture
|
||
|
||
### Layer 1: Compact (Quick Reference)
|
||
- **SKILL.md** (38 lines): Lambda contract, constraints, usage
|
||
- **examples/** (86 lines): Demonstration with metrics
|
||
|
||
### Layer 2: Reference (Detailed Guidance)
|
||
- **patterns.md** (247 lines): Core patterns with selection guide
|
||
- **integration-patterns.md** (385 lines): Claude Code feature integration
|
||
- **symbolic-language.md** (555 lines): Complete formal syntax
|
||
|
||
### Layer 3: Deep Dive (Analysis)
|
||
- **case-studies/** (484 lines): Design rationale, trade-offs, validation
|
||
|
||
**Design principle**: Start compact, dive deeper as needed.

## Automation Scripts
|
||
|
||
### count-artifacts.sh
|
||
Validates line counts for compactness compliance.
|
||
|
||
```bash
|
||
./scripts/count-artifacts.sh
|
||
```
|
||
|
||
**Output**: SKILL.md, examples, templates, reference line counts with compliance status.
|
||
|
||
### extract-patterns.py
|
||
Extracts and summarizes patterns from reference files.
|
||
|
||
```bash
|
||
python3 ./scripts/extract-patterns.py
|
||
```
|
||
|
||
**Output**: `inventory/patterns-summary.json` (4 patterns, 4 integration patterns, 20 symbols)
|
||
|
||
### generate-frontmatter.py

||
Generates frontmatter inventory from SKILL.md.
|
||
|
||
```bash
|
||
python3 ./scripts/generate-frontmatter.py
