# Technical Specification: [Feature Name]

## Metadata
- **Status**: Draft | In Review | Approved
- **Author**: [Name]
- **Reviewers**: [Names]
- **Last Updated**: [Date]

## Executive Summary
[2-3 sentences: What problem does this solve? What's the proposed solution?]

## Background & Context
- Current pain points
- Why now?
- Related work

## Goals
### Primary Goals
1. [Measurable goal]

### Non-Goals
- [What this spec explicitly does NOT cover]

## Functional Requirements
| ID | Requirement | Priority |
|----|-------------|----------|
| FR-1 | [Description] | P0 |
| FR-2 | [Description] | P1 |

## Non-Functional Requirements
- **Performance**: Response time < 200ms
- **Scalability**: Support 10K concurrent users
- **Availability**: 99.9% uptime
- **Security**: [Requirements]

## Technical Design

### Architecture
[Diagram or description]

### API Design

POST /api/v1/resource Request: { "field": "value" } Response: { "id": "123", "field": "value" }

### Database Schema

CREATE TABLE resources ( id UUID PRIMARY KEY, field VARCHAR(255) );

## Implementation Plan
| Phase | Timeline | Deliverables |
|-------|----------|--------------|
| 1 | Week 1-2 | Core functionality |
| 2 | Week 3 | API endpoints |
| 3 | Week 4 | Testing & docs |

## Testing Strategy
- Unit tests: 80% coverage
- Integration tests: API endpoints
- E2E tests: Critical flows

## Risks & Mitigations
| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| [Risk] | Medium | High | [Plan] |

## Success Criteria
- [ ] All P0 requirements implemented
- [ ] Tests passing
- [ ] Performance targets met
- [ ] Documentation complete

Full Template

See references/template.md for a comprehensive copy-paste template including:

• Complete metadata section
• Success metrics tables
• Architecture diagrams
• Detailed API design sections
• Security threat analysis
• Monitoring & observability
• Risk assessment matrix
• Rollout and rollback plans
• Dependencies tracking
• Open questions section

Best Practices

Do:

• Include measurable acceptance criteria
• Add architecture diagrams
• Define explicit API contracts
• Quantify performance targets
• Document risks and mitigations
• Get stakeholder review before implementation
• Include security considerations
• Define rollback procedures

Don't:

• Use vague requirements ("fast", "scalable")
• Skip non-functional requirements
• Ignore security considerations
• Leave alternatives unexplored
• Omit testing strategy
• Forget dependencies and risks
