project-init（项目初始化）

project-init

Purpose

Provide AI assistants with structured guidance for initializing brand new (greenfield) projects using the AI Dev Flow framework. This skill handles the one-time setup process that must occur BEFORE workflow execution begins.

⚠️ CRITICAL: This skill is for NEW PROJECT INITIALIZATION ONLY. For ongoing workflow execution on existing projects, use the doc-flow skill instead.

When to Use This Skill

Use project-init when:

• Starting a brand new project from scratch (greenfield)
• No project folders exist yet
• Domain has not been selected
• Project structure needs to be initialized

Do NOT use project-init when:

• Project already has docs/ folder structure
• Domain is already configured
• Working on existing project
• → Use doc-flow skill instead for workflow execution

Hand-off to doc-flow

After completing project initialization, AI Assistant MUST inform user:

✅ Project initialization complete!

Next: Use the `doc-flow` skill to begin workflow execution:
- Create BRD (Business Requirements)
- Create PRD (Product Requirements)
- Follow 15-layer architecture (Layers 0-14) with 11 artifact directories (BRD through TASKS): BRD → PRD → EARS → BDD → ADR → SYS → REQ → [IMPL] → [CTR] → SPEC → TASKS → Code → Tests → Validation

Initialization Workflow (8 Steps)

Step 0: Read Execution Rules

File: AI_ASSISTANT_RULES.md

Purpose: Understand core execution rules before starting

Key Rules:

1. Domain Selection FIRST
2. Create Folders BEFORE Documents
3. Apply Domain Configuration
4. Run Contract Questionnaire
5. Initialize Index Files
6. Validate Setup
7. Token Optimization
8. Tool-Specific Guidance

Action: AI Assistant reads this file to understand all 15 rules

Step 1: Domain Selection (REQUIRED FIRST)

File: DOMAIN_SELECTION_QUESTIONNAIRE.md

Purpose: Determine project domain to load correct configuration

AI Assistant Action: Present questionnaire to user

═══════════════════════════════════════════════════════════
                 PROJECT DOMAIN SELECTION
═══════════════════════════════════════════════════════════

What is the purpose and focus of this new project?

Select one:

1. Financial Services (DEFAULT)
   - Trading platforms, banking, insurance, portfolio management
   - Regulatory: SEC, FINRA, SOX, Basel III, PCI-DSS

2. Software/SaaS
   - B2B/B2C software services, multi-tenant applications
   - Regulatory: SOC2, GDPR/CCPA, ISO 27001

3. Healthcare
   - EMR, telemedicine, medical devices, patient management
   - Regulatory: HIPAA, FDA, HITECH, 21 CFR Part 11

4. E-commerce
   - Retail, marketplace, subscription services
   - Regulatory: PCI-DSS, GDPR/CCPA, FTC

5. IoT (Internet of Things)
   - Connected devices, sensors, industrial systems
   - Regulatory: FCC, CE, UL/IEC, FDA (medical devices)

6. Other/Generic
   - Internal tools, utilities, custom domain
   - Regulatory: Company policies only

Enter selection (1-6) or press Enter for default (1):

Output: Domain selected, configuration file determined

Domain Configuration Mapping:

Step 2: Folder Structure Creation (REQUIRED SECOND)

Rule: AI Assistant MUST create complete directory structure BEFORE creating any documents.

Why: Prevents "file not found" errors, ensures proper organization

IMPORTANT: Ensure project root directory exists first:

# Create project root directory if it doesn't exist
mkdir -p {project_root}
cd {project_root}

Replace {project_root} with your actual project path (e.g., /opt/data/my_project)

Commands to Execute:

# Core 11 artifact directories (BRD through TASKS)
mkdir -p docs/BRD
mkdir -p docs/PRD
mkdir -p docs/EARS
mkdir -p docs/BDD
mkdir -p docs/ADR
mkdir -p docs/SYS
mkdir -p docs/REQ
mkdir -p docs/IMPL
mkdir -p docs/CTR
mkdir -p docs/SPEC
mkdir -p docs/TASKS

# NOTE: REQ and CTR subdirectories are created on-demand by doc-req and doc-ctr skills
# when documents are generated. This ensures folders match actual project needs.

# Scripts directory
mkdir -p scripts

# Work plans directory (for /save-plan command output)
mkdir -p work_plans

Validation:

ls -la docs/  # Verify 11 artifact directories created
ls -la work_plans/  # Verify work_plans directory

Step 3: Load Domain Configuration

Files:

• FINANCIAL_DOMAIN_CONFIG.md - Default
• SOFTWARE_DOMAIN_CONFIG.md
• GENERIC_DOMAIN_CONFIG.md

Purpose: Apply domain-specific terminology and placeholders

AI Assistant Action:

1. Read selected domain configuration file
2. Extract placeholder mappings
3. Store terminology for document generation

Example Mappings:

Financial Services:

[RESOURCE_COLLECTION] → Portfolio
[RESOURCE_ITEM] → Position
[USER_ROLE] → Trader / Portfolio Manager
[TRANSACTION] → Trade
[REGULATORY_REQUIREMENT] → SEC Rule 15c3-5

Software/SaaS:

[RESOURCE_COLLECTION] → Workspace
[RESOURCE_ITEM] → Resource
[USER_ROLE] → Account Admin / Member
[TRANSACTION] → API Call
[REGULATORY_REQUIREMENT] → SOC2 Control

Generic:

[RESOURCE_COLLECTION] → Collection
[RESOURCE_ITEM] → Entity
[USER_ROLE] → User
[TRANSACTION] → Action
[REGULATORY_REQUIREMENT] → Company Policy

Step 4: Template Copying (Optional)

Purpose: Copy framework templates to project (optional step)

Commands:

# Create ai_dev_flow directory for framework templates
mkdir -p ai_dev_flow

# Copy all templates (if framework templates exist)
cp -r {framework_root}/ai_dev_flow/* ai_dev_flow/

# Copy validation scripts
cp {framework_root}/ai_dev_flow/scripts/*.py scripts/

Directory Purpose:

• ai_dev_flow/ = Framework templates (BRD-TEMPLATE.md, examples/, etc.)
• docs/ = Project documentation (BRD-01.md, PRD-01.md, etc.)

Note: This step is optional. Templates can also be referenced directly from framework location.

Step 5: Contract Decision (REQUIRED)

File: CONTRACT_DECISION_QUESTIONNAIRE.md

Purpose: Determine if CTR (Contracts) layer should be included in workflow

AI Assistant Action: Present questionnaire to user

═══════════════════════════════════════════════════════════
              CONTRACT DECISION QUESTIONNAIRE
═══════════════════════════════════════════════════════════

Does this project require API contracts or interface definitions?

Select all that apply:

1. ☐ REST/GraphQL APIs (External HTTP endpoints)
2. ☐ Event Schemas (Pub/Sub, message queues, webhooks)
3. ☐ Data Contracts (Shared database schemas, data models between services)
4. ☐ RPC/gRPC Interfaces (Service-to-service communication)
5. ☐ WebSocket APIs (Real-time bidirectional communication)
6. ☐ File Format Specifications (CSV, JSON, XML exchange formats)
7. ☐ None - Internal logic only
8. ☐ Unsure - Need guidance

Enter selections (comma-separated, e.g., "1,2" or single "7"):

Decision Matrix:

Output: Workflow determined (with or without CTR layer)

Step 6: Index File Initialization + Document Control

Purpose: Create index files for each document type

Document Control Requirements: All AI Dev Flow templates include a Document Control section with:

• Project metadata (name, version, date, owner, preparer, status)
• Document Revision History table
• Essential for traceability, change management, and regulatory compliance

AI Assistant Must Emphasize: When creating documents from templates, users must complete the Document Control section with all required fields.

Commands:

# Create index files
touch docs/BRD/BRD-00_index.md
touch docs/prd/PRD-00_index.md
touch docs/ears/EARS-00_index.md
touch docs/BDD/BDD-00_index.md
touch docs/adrs/ADR-00_index.md
touch docs/sys/SYS-00_index.md
touch docs/REQ/REQ-00_index.md
touch docs/IMPL/IMPL-00_index.md
touch docs/CTR/CTR-00_index.md
touch docs/specs/SPEC-00_index.yaml
touch docs/TASKS/TASKS-00_index.md

Index File Purpose:

• Track all documents of each type
• Provide next available ID
• Document registry with status

Step 7: Validation

Purpose: Verify setup complete and correct

Validation Commands:

# Verify directory structure
ls -laR docs/

# Verify index files exist
ls docs/*/index.* || ls docs/*/*_index.*

# Expected: 11 artifact directories (BRD through TASKS) + domain subdirectories
# Expected: 11 index files

Success Criteria:

• ✅ All 11 artifact directories exist (BRD, PRD, EARS, BDD, ADR, SYS, REQ, IMPL, CTR, SPEC, TASKS)
• ✅ Domain-specific subdirectories exist (risk/, trading/, tenant/, etc.)
• ✅ All index files created
• ✅ All templates include Document Control sections
• ✅ Validation scripts present (if copied)
• ✅ work_plans directory exists (for /save-plan command)

Error Handling:

• If folders missing: Re-run Step 2
• If index files missing: Re-run Step 6
• If domain subdirs missing: Check Step 1 domain selection

Step 8: Project Ready - Hand-off to doc-flow

Troubleshooting

Issue: Directory Already Exists

Error: mkdir: cannot create directory 'docs': File exists

Resolution:

• Project may already be initialized
• Verify: ls -la docs/
• If folders exist, skip to doc-flow skill
• If folders incomplete, delete and re-run project-init

Issue: Permission Denied

Error: mkdir: cannot create directory: Permission denied

Resolution:

• Check current working directory permissions
• Ensure write access to parent directory
• Use pwd to verify location

Issue: Domain Unclear

User says: "I'm not sure which domain to choose"

AI Assistant Action: Run follow-up questions from DOMAIN_SELECTION_QUESTIONNAIRE.md:

1. Does project involve financial transactions? → Financial Services
2. Multi-tenant SaaS application? → Software/SaaS
3. Handle patient health information? → Healthcare
4. Online store or marketplace? → E-commerce
5. Connected devices or sensors? → IoT
6. None of above? → Generic
