Technical Domain

Document the technical foundation, architecture, and key decisions.

Quick Reference

Purpose: Understand how the project works technically
Update When: New features, refactoring, tech stack changes
Audience: Developers, DevOps, technical stakeholders

Primary Stack

Layer	Technology	Version	Rationale
Language	[e.g., TypeScript]	[Version]	[Why this language]
Framework	[e.g., Node.js]	[Version]	[Why this framework]
Database	[e.g., PostgreSQL]	[Version]	[Why this database]
Infrastructure	[e.g., AWS, Vercel]	[N/A]	[Why this infra]
Key Libraries	[List important ones]	[Versions]	[Why each matters]

Architecture Pattern

Type: [Monolith | Microservices | Serverless | Agent-based | Hybrid]
Pattern: [Brief description]
Diagram: [Link to architecture diagram if exists]

Why This Architecture?

[Explain the business and technical reasons for this architecture choice. What problem does this architecture solve? What were alternatives considered?]

Project Structure

[Project Root]
├── src/                    # Source code
├── tests/                  # Test files
├── docs/                   # Documentation
├── scripts/                # Build/deploy scripts
└── [Other key directories]

Key Directories:

src/ - Contains all application logic organized by [module/feature/domain]
tests/ - [How tests are organized]
docs/ - [What documentation lives here]

Key Technical Decisions

Decision	Rationale	Impact
[Decision 1]	[Why this choice]	[What it enables]
[Decision 2]	[Why this choice]	[What it enables]

See decisions-log.md for full decision history with alternatives.

Integration Points

System	Purpose	Protocol	Direction
[API 1]	[What it does]	[REST/GraphQL/gRPC]	[Inbound/Outbound]
[Database]	[What it stores]	[PostgreSQL/Mongo/etc]	[Internal]
[Service]	[What it provides]	[HTTP/gRPC]	[Outbound]

Technical Constraints

Constraint	Origin	Impact
[Legacy systems]	[Business/Tech]	[What limitation it creates]
[Compliance]	[Regulation]	[What must be followed]
[Performance]	[SLAs]	[What must be met]

Development Environment

Setup: [Quick setup command or link]
Requirements: [What developers need installed]
Local Dev: [How to run locally]
