## Making Changes

### Branch Naming

Use descriptive branch names:
- `feature/description` — New features
- `fix/description` — Bug fixes
- `docs/description` — Documentation updates
- `refactor/description` — Code refactoring

### Commit Messages

Follow conventional commits:
```
type(scope): description

[optional body]

[optional footer]
```

Types:
- `feat` — New feature
- `fix` — Bug fix
- `docs` — Documentation
- `style` — Formatting, no code change
- `refactor` — Code restructuring
- `test` — Adding tests
- `chore` — Maintenance

Examples:
```
feat(scope): add indentation-based fallback for scope resolution
fix(patch): handle missing if-wrapper in SEARCH/REPLACE block
docs(readme): update commands reference for current state
```

## Submitting Changes

1. Ensure your code follows the style guide
2. Update documentation if needed
3. Update `CHANGELOG.md` for notable changes
4. Test your changes thoroughly
5. Create a pull request with:
   - Clear title describing the change
   - Description of what and why
   - Reference to any related issues

### Pull Request Template

```markdown
## Description
[Describe your changes]

## Type of Change
- [ ] Bug fix
- [ ] New feature
- [ ] Documentation update
- [ ] Refactoring

## Testing
[Describe how you tested your changes]

## Checklist
- [ ] Code follows style guide
- [ ] Documentation updated
- [ ] CHANGELOG.md updated
- [ ] All tests pass
```

## Style Guide

### Lua Style

- Use tabs for indentation
- Use `snake_case` for variables and functions
- Use `PascalCase` for module names
- Add type annotations with `---@param`, `---@return`, etc.
- Document public functions with LuaDoc comments
- Avoid obvious/redundant comments

```lua
---@mod module_name Module description

local M = {}

--- Description of the function
---@param name string The parameter description
---@return boolean
function M.example_function(name)
  return true
end

return M
```

### Documentation

- Keep `README.md` up to date
- Update `doc/codetyper.txt` for new features
- Regenerate `doc/tags` after help file changes
- Use clear, concise language
- Include examples where helpful

## Testing

### Running Tests

```bash
make test              # Run all tests
make test-file F=x     # Run a specific test file
make test-verbose      # Verbose output
make lint              # Run luacheck
make format            # Format with stylua
```

### Manual Testing

1. Test all commands work correctly
2. Test with different file types
3. Test LLM integration (Copilot and Ollama)
4. Test edge cases (empty files, large files, no Tree-sitter, etc.)
5. Run `:checkhealth codetyper`
