Project Planner Skill

Purpose: Generate comprehensive project documentation from high-level descriptions.

Trigger Words: new project, project overview, project spec, technical requirements, project planning, architecture, system design

Quick Decision: Use Project Planning?

def needs_project_planning(context: dict) -> bool:
    """Fast evaluation for project-level planning."""

    # Indicators of project-level work
    project_indicators = [
        "new project", "project overview", "system design",
        "architecture", "technical requirements", "project spec",
        "build a", "create a", "develop a platform",
        "microservices", "full stack", "api + frontend"
    ]

    description = context.get("description", "").lower()
    return any(indicator in description for indicator in project_indicators)

Security Considerations

OWASP Top 10 Coverage

1. Injection: Parameterized queries, input validation
2. Broken Auth: JWT with refresh tokens, secure session management
3. Sensitive Data: Encryption at rest and in transit
4. XXE: Disable XML external entities
5. Broken Access Control: RBAC enforcement
6. Security Misconfiguration: Secure defaults, regular audits
7. XSS: Output escaping, CSP headers
8. Insecure Deserialization: Validate all input
9. Known Vulnerabilities: Dependency scanning (Snyk, Dependabot)
10. Insufficient Logging: Audit logs for sensitive actions

---

Monitoring & Observability

Metrics

• Request rate, error rate, latency (RED method)
• Database connection pool usage
• Cache hit/miss ratio
• Background job queue length

Logging

• Structured JSON logs
• Centralized logging (ELK stack or CloudWatch)
• Log levels: DEBUG (dev), INFO (staging), WARN/ERROR (prod)

Alerting

• Error rate >5% (P1)
• API latency >500ms (P2)
• Database connections >80% (P2)
• Disk usage >90% (P1)

---

Documentation Requirements

• API documentation (OpenAPI/Swagger)
• Setup guide (README.md)
• Architecture diagrams
• Deployment runbook
• Troubleshooting guide

---

## Generation Process

### Step 1: Extract Project Context
```python
def extract_project_info(prompt: str) -> dict:
    """Parse project description for key details."""

    info = {
        "name": None,
        "description": prompt,
        "features": [],
        "tech_stack": [],
        "constraints": {},
        "goals": []
    }

    # Extract from prompt:
    # - Project name (if mentioned)
    # - Desired features
    # - Technology preferences
    # - Timeline/budget constraints
    # - Success metrics

    return info

Step 2: Apply Output Style

Use output-style-selector to determine:

• PROJECT-OVERVIEW.md: Bullet-points, concise
• SPECIFICATIONS.md: Table-based for API contracts, YAML-structured for models

Step 3: Generate Documents

1. Create project-management/ directory if needed
2. Write PROJECT-OVERVIEW.md (vision-focused)
3. Write SPECIFICATIONS.md (technical details)
4. Validate completeness

Step 4: Validation Checklist

## Generated Documents Validation

PROJECT-OVERVIEW.md:
- [ ] Project name and tagline present
- [ ] Vision statement (2-3 sentences)
- [ ] 3+ goals defined
- [ ] 5-10 key features listed
- [ ] Success criteria measurable
- [ ] Constraints documented
- [ ] Out-of-scope items listed

SPECIFICATIONS.md:
- [ ] Functional requirements detailed
- [ ] Non-functional requirements (perf, security, reliability)
- [ ] API contracts with examples (if applicable)
- [ ] Data models defined
- [ ] Architecture overview
- [ ] Dependencies listed
- [ ] Development phases outlined
- [ ] Testing strategy included

Integration with Commands

With /lazy plan

# Generate project docs first
/lazy plan --project "Build AI-powered task manager"

→ project-planner skill triggers
→ Generates PROJECT-OVERVIEW.md + SPECIFICATIONS.md
→ Then creates first user story from specifications

# Or start from enhanced prompt
/lazy plan --file enhanced_prompt.md

→ Detects project-level scope
→ Runs project-planner
→ Creates foundational docs
→ Proceeds with story creation

With /lazy code

# Reference specifications during implementation
/lazy code @US-3.4.md

→ context-packer loads SPECIFICATIONS.md
→ API contracts and data models available
→ Implementation follows spec

---

What This Skill Does NOT Do

❌ Generate actual code (that's for coder agent) ❌ Create user stories (that's for project-manager agent) ❌ Make architectural decisions (provides template, you decide) ❌ Replace technical design documents (TDDs)

✅ DOES: Create structured foundation documents for new projects.

---

Configuration

# Minimal specs (faster, less detail)
export LAZYDEV_PROJECT_SPEC_MINIMAL=1

# Skip API contracts (non-API projects)
export LAZYDEV_PROJECT_NO_API=1

# Focus on specific aspects
export LAZYDEV_PROJECT_FOCUS="security,performance"

---

Tips for Effective Project Planning

For PROJECT-OVERVIEW.md

1. Vision: Think big picture - why does this exist?
2. Goals: Limit to 3-5 measurable outcomes
3. Features: High-level only (not task-level details)
4. Success Criteria: Must be measurable (numbers, percentages)

For SPECIFICATIONS.md

1. API Contracts: Start with authentication and core resources
2. Data Models: Include relationships and constraints
3. Non-Functional: Don't skip - these prevent tech debt
4. Security: Reference OWASP Top 10 coverage
5. Phases: Break into 2-3 month chunks maximum

Best Practices

• Keep PROJECT-OVERVIEW under 2 pages: Executive summary only
• SPECIFICATIONS can be longer: This is the source of truth
• Update specs as you learn: Living documents
• Version control both: Track changes over time

Example Trigger Scenarios

Scenario 1: New Greenfield Project

User: "I want to build a real-time chat platform with video calls"

→ project-planner triggers
→ Generates:
  - PROJECT-OVERVIEW.md (vision: modern communication platform)
  - SPECIFICATIONS.md (WebSocket APIs, video streaming, etc.)
→ Ready for user story creation

Scenario 2: From Enhanced Prompt

User: /lazy plan --file enhanced_prompt.md
# enhanced_prompt contains: detailed project requirements, tech stack, timeline

→ project-planner parses prompt
→ Extracts structured information
→ Generates both documents
→ Proceeds to first user story

Scenario 3: Partial Information

User: "Build a task manager, not sure about details yet"

→ project-planner generates template
→ Marks sections as [TODO: Specify...]
→ User fills in gaps incrementally
→ Re-generate or update manually
