Build Research Skill - Phase 1 Research Dispatcher

Auto-Delegation Trigger (CRITICAL)

Reference: .claude/​skills/​shared/​auto-delegation.md Behavior: When agent_delegation.enabled: true AND default_mode: true, skill automatically operates as Sub-Orchestrator.

// AUTO-DELEGATION CHECK - Execute at skill invocation
// If complex task detected, triggers: analyze → delegate → collect
const delegationDecision = checkAutoDelegation(SKILL_CONFIG, userRequest)
if (delegationDecision.shouldDelegate) {
  const complexity = analyzeTaskComplexity(taskDescription, SKILL_CONFIG)
  return executeDelegation(taskDescription, complexity, SKILL_CONFIG)
}
// Simple tasks execute directly without delegation overhead

Build Research Skill - Phase 1 Research Dispatcher

Version: 3.0.0 | Context: fork | Model: opus Parent: /​build command | Phase: 1 of 3

---

Purpose

Execute Phase 1 (RESEARCH) of the enhanced /​build workflow:

1. Parse concept name from user input ($ARGUMENTS)
2. Delegate research to claude-code-guide subagent
3. Generate capability inventory
4. Save results with resume support
5. Return L1 summary to Main Agent

---

1. Input Parsing

Supported Input Patterns

Pattern 1: /​build "Progressive-Disclosure"     → concept = "Progressive-Disclosure"
Pattern 2: /​build concept-name                 → concept = "concept-name"
Pattern 3: /​build --research "concept-name"    → concept = "concept-name"
Pattern 4: $ARGUMENTS directly                 → concept = $ARGUMENTS.strip()

Build ID Generation (표준 Workload 시스템)

# Source centralized slug generator
source "${WORKSPACE_ROOT:-.}/​.claude/​skills/​shared/​slug-generator.sh"
source "${WORKSPACE_ROOT:-.}/​.claude/​skills/​shared/​workload-files.sh"

# 기본 동작: 항상 새 workload 생성 (독립 스킬)
CONCEPT="$1"
TOPIC="build-${CONCEPT:-research}"

# Workload ID 생성
WORKLOAD_ID=$(generate_workload_id "$TOPIC")
SLUG=$(generate_slug_from_workload "$WORKLOAD_ID")

# Short ID for display (레거시 호환)
BUILD_ID="${CONCEPT:0:3}-$(echo "$WORKLOAD_ID" | md5sum | cut -c1-4)"

# 디렉토리 구조 초기화
BUILD_DIR=".agent/​builds/​${SLUG}"
mkdir -p "${BUILD_DIR}"

# Workload 활성화
set_active_workload "$WORKLOAD_ID"

echo "🔬 Build research initialized: $SLUG (ID: $BUILD_ID)"

레거시 호환:

Format: {concept_slug[:3]}-{hash[:4]}
Example: "pro-a1b2" for "Progressive-Disclosure"

2. Research Delegation

Claude-Code-Guide Prompt

## Context
User wants to build a "{concept}" implementation using Claude Code native capabilities.

## Task
Research ALL relevant Claude Code native capabilities that could implement "{concept}".

## Required Output Format (JSON)
{
  "concept": "{concept}",
  "capabilities": [
    {
      "id": "S1",
      "name": "capability name",
      "category": "skill|agent|hook|pattern",
      "complexity": "basic|intermediate|advanced",
      "level": 0|50|100,
      "description": "1-2 sentence description",
      "fields": ["field1", "field2"],
      "dependencies": ["other_capability_id"]
    }
  ],
  "levels": {
    "0": {
      "name": "Basic",
      "capabilities": ["S1", "H1"],
      "capabilityCount": 2,
      "description": "Core functionality only"
    },
    "50": {
      "name": "Recommended",
      "capabilities": ["S1", "S2", "H1", "H2", "A1"],
      "capabilityCount": 5,
      "description": "Standard implementation with error handling"
    },
    "100": {
      "name": "Full",
      "capabilities": ["S1", "S2", "S3", "H1", "H2", "H3", "A1", "A2"],
      "capabilityCount": 8,
      "description": "Complete implementation with all features"
    }
  },
  "summary": {
    "total_capabilities": 8,
    "by_category": {"skill": 3, "agent": 2, "hook": 3, "pattern": 0},
    "recommended_level": 50,
    "estimated_complexity": "medium"
  }
}

## Research Areas
1. **Skills**: .claude/​skills/ patterns, frontmatter fields, execution modes
2. **Agents**: .claude/​agents/ patterns, tool restrictions, delegation
3. **Hooks**: Hook event types (13 events), input/​output schemas
4. **Patterns**: Orchestration patterns, runtime chaining
5. **Task Tool**: Subagent delegation options

## Constraints
- Only include capabilities directly relevant to "{concept}"
- Categorize by complexity (basic/​intermediate/​advanced)
- Group into 3 implementation levels (0/​50/​100)
- Include dependencies between capabilities

9. Master Reference Files

capability_index.json

Location: .agent/​builds/​master/​capability_index.json

Contains comprehensive capability inventory from claude-code-guide research.

complexity_levels.json

Location: .agent/​builds/​master/​complexity_levels.json

Defines Level 0/​50/​100 with capability counts and examples.

---

Instructions

When invoked with $ARGUMENTS containing a concept name:

1. Parse the concept from $ARGUMENTS (remove quotes if present)
2. Generate build_id using format {slug[:3]}-{hash[:4]}
3. Check for existing build at .agent/​builds/​{build_id}/​research.json
   • If exists, return existing L1 summary
4. Delegate to claude-code-guide with the research prompt above
5. Parse the JSON response and validate structure
6. Create directory .agent/​builds/​{build_id}/
7. Save research.json with capability inventory
8. Initialize selection.json and artifacts.json (empty, for Phase 2/​3)
9. Return L1 summary (max 500 tokens) with:
   • Build ID
   • Concept name
   • Complexity level options (0/​50/​100 with capability counts)
   • l2Path pointing to research.json
   • nextActionHint for Phase 2

const researchPrompt = `
## Internal Feedback Loop (P6 - REQUIRED)
1. Generate capability inventory
2. Self-validate JSON structure:
   - All required fields present
   - Level 0/​50/​100 properly defined
   - Dependencies are valid references
3. If validation fails, retry (max 3 times)
4. Output valid JSON after validation passes
