Architecture

Manage the project's tech stack and architecture decisions.

Instructions

Ask the user what they want to do:

1. Update tech stack - Add or modify technologies in docs/strategy/tech-stack.md
2. New decision - Create an Architecture Decision Record in docs/strategy/architecture/
3. Review decisions - List existing ADRs and check if any need updating

Option 1: Update Tech Stack

1. Check if docs/strategy/tech-stack.md exists
2. If it exists, read it and ask what to add/change
3. If it doesn't exist, gather the current tech stack through conversation
4. Update or create the file

Tech stack document should cover:

• Languages - Programming languages used
• Frameworks - Core frameworks
• Infrastructure - Hosting, CI/CD, etc.
• Data - Databases, caching, etc.
• Key Libraries - Important dependencies

Option 2: New Decision

Create a new ADR in docs/strategy/architecture/. Use numbered filenames like 001-title.md.

1. Check existing ADRs to determine the next number
2. Ask the user about:
   • Title: Short name for the decision
   • Context: Why are we making this decision? What's the situation?
   • Decision: What did we decide?
   • Consequences: What does this mean going forward? (good and bad)
3. Create the ADR with status "accepted"

ADR format:

# [NUMBER]. [TITLE]

**Status**: accepted

## Context

[Why we're making this decision]

## Decision

[What we decided]

## Consequences

[What this means - both positive and negative]

Option 3: Review Decisions

1. List all ADRs in docs/strategy/architecture/
2. Show a summary of each (title + status)
3. Ask if any decisions need to be revisited
4. If yes, update the status (deprecated, superseded) and optionally create a new ADR

Output Locations

• Tech stack: docs/strategy/tech-stack.md
• ADRs: docs/strategy/architecture/NNN-title.md

Notes

• Keep ADRs concise - capture the essence, not every detail
• ADRs are immutable once accepted - create new ones to supersede old decisions
• Tech stack should reflect what's actually in use, not aspirational
