+# Project Audit Skill
+
+## Trigger
+`/project-audit [absolute_path]` or "프로젝트 감사", "코드 리뷰"
+
+## Description
+Runs all 8 dev review agents on a given directory path. Produces a unified audit report.
+
+## Input
+- Absolute directory path (e.g., `/Users/user/projects/my-app`)
+- The path MUST exist and contain a development project
+
+## Execution Workflow
+
+### Step 1: Reconnaissance
+- Scan directory structure (Glob)
+- Identify project type (language, framework)
+- Find entry points, configs, package manifests
+
+### Step 2: Parallel Analysis (4 agents)
+- `dev-architecture`: Structure and design
+- `dev-code-quality`: Code smells and readability
+- `dev-security`: Vulnerabilities and secrets
+- `dev-supply-chain`: Dependencies and licenses
+
+### Step 3: Parallel Analysis (4 agents, may use Step 2 context)
+- `dev-performance`: Bottlenecks
+- `dev-docs-sync`: Documentation accuracy
+- `dev-devops`: CI/CD and deployment
+- `dev-test-coverage`: Test quality
+
+### Step 4: Unified Report
+Merge all 8 agent results into a single audit document.
+
+## Context Window Management (Layered Analysis)
+For large projects, each agent follows this scan strategy:
+1. **L1 (Always)**: Entry points, configs, package manifests, README
+2. **L2 (Core)**: Core business logic, domain layer, API routes
+3. **L3 (On demand)**: Utilities, helpers, generated code — only if L1/L2 findings indicate issues
+
+## Output Format
+Final deliverable in **Korean (한국어)**.

+| Architecture | | 🟢/🟡/🔴 | |

+## 상세 보고서 링크
+- [Architecture](./dev-architecture-report.md)
+- [Code Quality](./dev-code-quality-report.md)
+- ...
+```
+
+## Brutal Analysis Principles
+- Scores must reflect reality. A project with no tests and hardcoded secrets cannot score above 30
+- Cross-reference findings between agents (e.g., security finding + missing test = compounded risk)
+
+## Claude-Gemini Cross-Debate Protocol
+Each agent step includes Claude-Gemini debate. The unified report is also Gemini-reviewed.
