## Our Philosophy

BMad strengthens human-AI collaboration through specialized agents and guided workflows. Every contribution should answer: **"Does this make humans and AI better together?"**

**✅ What we welcome:**
- Enhanced collaboration patterns and workflows
- Improved agent personas and prompts
- Domain-specific modules leveraging BMad Core
- Better planning and context continuity

**❌ What doesn't fit:**
- Purely automated solutions that sideline humans
- Complexity that creates barriers to adoption
- Features that fragment BMad Core's foundation

## Reporting Issues

**ALL bug reports and feature requests MUST go through GitHub Issues.**

### Before Creating an Issue

1. **Search existing issues** — Use the GitHub issue search to check if your bug or feature has already been reported
2. **Search closed issues** — Your issue may have been fixed or addressed previously
3. **Check discussions** — Some conversations happen in [GitHub Discussions](https://github.com/bmad-code-org/BMAD-METHOD/discussions)

### Bug Reports

After searching, if the bug is unreported, use the [bug report template](https://github.com/bmad-code-org/BMAD-METHOD/issues/new?template=bug_report.md) and include:

- Clear description of the problem
- Steps to reproduce
- Expected vs actual behavior
- Your environment (model, IDE, BMad version)
- Screenshots or error messages if applicable

### Feature Requests

After searching, use the [feature request template](https://github.com/bmad-code-org/BMAD-METHOD/issues/new?template=feature_request.md) and explain:

- What the feature is
- Why it would benefit the BMad community
- How it strengthens human-AI collaboration

**For community modules**, review [TRADEMARK.md](TRADEMARK.md) for proper naming conventions (e.g., "My Module (BMad Community Module)").

## Before Starting Work

⚠️ **Required before submitting PRs:**

| Work Type     | Requirement                                    |
| ------------- | ---------------------------------------------- |
| Bug fix       | An open issue (create one if it doesn't exist) |
| Feature       | An open feature request issue                  |
| Large changes | Discussion via issue first                     |

**Why?** This prevents wasted effort on work that may not align with project direction.

## Pull Request Guidelines

### Target Branch

Submit PRs to the `main` branch. We use trunk-based development. Every push to `main` auto-publishes to `npm` under the `next` tag. Stable releases are cut ~weekly to the `latest` tag.

### PR Size

- **Ideal**: 200-400 lines of code changes
- **Maximum**: 800 lines (excluding generated files)
- **One feature/fix per PR**

If your change exceeds 800 lines, break it into smaller PRs that can be reviewed independently.

### New to Pull Requests?

1. **Fork** the repository
2. **Clone** your fork: `git clone https://github.com/YOUR-USERNAME/bmad-method.git`
3. **Create a branch**: `git checkout -b fix/description` or `git checkout -b feature/description`
4. **Make changes** — keep them focused
5. **Commit**: `git commit -m "fix: correct typo in README"`
6. **Push**: `git push origin fix/description`
7. **Open PR** from your fork on GitHub

### PR Description Template

```markdown
## What
[1-2 sentences describing WHAT changed]

## Why
[1-2 sentences explaining WHY this change is needed]
Fixes #[issue number]

## How
- [2-3 bullets listing HOW you implemented it]
-

## Testing
[1-2 sentences on how you tested this]
```

**Keep it under 200 words.**

### Commit Messages

Use conventional commits:

- `feat:` New feature
- `fix:` Bug fix
- `docs:` Documentation only
- `refactor:` Code change (no bug/feature)
- `test:` Adding tests
- `chore:` Build/tools changes

Keep messages under 72 characters. Each commit = one logical change.

## What Makes a Good PR?

| ✅ Do                        | ❌ Don't                      |
| --------------------------- | ---------------------------- |
| Change one thing per PR     | Mix unrelated changes        |
| Clear title and description | Vague or missing explanation |
| Reference related issues    | Reformat entire files        |
| Small, focused commits      | Copy your whole project      |
| Work on a branch            | Work directly on `main`      |

---

## Prompt & Agent Guidelines

- Keep dev agents lean — focus on coding context, not documentation
- Web/planning agents can be larger with complex tasks
- Everything is natural language (markdown) — no code in core framework
- Use BMad modules for domain-specific features
- Validate YAML schemas: `npm run validate:schemas`
- Validate file references: `npm run validate:refs`

### File-Pattern-to-Validator Mapping

| File Pattern | Validator | Extraction Function |
| ------------ | --------- | ------------------- |
| `*.yaml`, `*.yml` | `validate-file-refs.js` | `extractYamlRefs` |
| `*.md`, `*.xml` | `validate-file-refs.js` | `extractMarkdownRefs` |
| `*.csv` | `validate-file-refs.js` | `extractCsvRefs` |
