# architecture-decision-record

Create Architecture Decision Records with a Nygard-style structure. Use the skill to capture why a choice was made, what follows from it, and which alternatives were weighed.

## What it does

The skill includes a Markdown template and a generator that fills in the ADR number, date, author, and total ADR count. The document structure covers context, decision, consequences, alternatives, and status, from Proposed to Accepted or Rejected. For a manual start, copy `assets/adr-template.md`.

Record at least two alternatives and explain why each was set aside. Number entries sequentially, such as `ADR-0001`, and keep the Markdown files in Git, for instance under `/docs/adr/`. Once accepted, an ADR stays unchanged; a later decision should replace it through a new record. The skill supplies the format, while the project team must provide the reasoning and decision details.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill architecture-decision-record -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/architecture-decision-record/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/architecture-decision-record/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill architecture-decision-record -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/architecture-decision-record/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill architecture-decision-record -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/architecture-decision-record/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install yonatangross/orchestkit architecture-decision-record
```

2. **Manually: put the files in place**
- File: `.github/skills/architecture-decision-record/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill architecture-decision-record -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/yonatangross/orchestkit --path src/skills/architecture-decision-record
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/architecture-decision-record/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill architecture-decision-record -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/yonatangross/orchestkit/tree/HEAD/src/skills/architecture-decision-record/SKILL.md

## When to use it
- record the reasoning behind an architecture choice
- describe the trade-offs of a decision
- compare options and document rejected alternatives
- keep decision history alongside code in Git

## Example prompts
- Create an ADR for moving to PostgreSQL with number 0004.
- Draft an architecture decision using `assets/adr-template.md`, including consequences and alternatives.
- Write a new ADR that supersedes `ADR-0003`.

# Architecture Decision Records
Architecture Decision Records (ADRs) are lightweight documents that capture important architectural decisions along with their context and consequences. This skill provides templates, examples, and best practices for creating and maintaining ADRs in your projects.

## Overview
- Making significant technology choices (databases, frameworks, cloud providers)
- Designing system architecture or major components
- Establishing patterns or conventions for the team
- Evaluating trade-offs between multiple approaches
- Documenting decisions that will impact future development

## Why ADRs Matter

ADRs serve as architectural memory for your team:
- **Context Preservation**: Capture why decisions were made, not just what was decided
- **Onboarding**: Help new team members understand architectural rationale
- **Prevent Revisiting**: Avoid endless debates about settled decisions
- **Track Evolution**: See how architecture evolved over time
- **Accountability**: Clear ownership and decision timeline

## ADR Format (Nygard Template)

Each ADR should follow this structure:

### 1. Title
Format: `ADR-####: [Decision Title]`
Example: `ADR-0001: Adopt Microservices Architecture`

### 2. Status
Current state of the decision:
- **Proposed**: Under consideration
- **Accepted**: Decision approved and being implemented
- **Superseded**: Replaced by a later decision (reference ADR number)
- **Deprecated**: No longer recommended but not yet replaced
- **Rejected**: Considered but not adopted (document why)

### 3. Context
**What to include:**
- Problem statement or opportunity
- Business/technical constraints
- Stakeholder requirements
- Current state of the system
- Forces at play (conflicting concerns)

### 4. Decision
**What to include:**
- The choice being made
- Key principles or patterns to follow
- What will change as a result
- Who is responsible for implementation

**Be specific and actionable:**
- ✅ "We will adopt microservices architecture using Node.js with Express"
- ❌ "We will consider using microservices"

### 5. Consequences
**What to include:**
- Positive outcomes (benefits)
- Negative outcomes (costs, risks, trade-offs)
- Neutral outcomes (things that change but aren't clearly better/worse)
