+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Bash-it is a collection of community Bash commands and scripts for Bash 3.2+, providing a framework for aliases, themes, plugins, and completions. It's structured as a modular system where components can be individually enabled or disabled.
+
+## Architecture
+
+### Core Components
+
+- **bash_it.sh**: Main entry point that initializes the framework
+- **lib/**: Core libraries providing utilities, logging, helpers, and appearance functions
+- **scripts/reloader.bash**: Component loader that sources enabled components
+- **install.sh**: Installation script with interactive and silent modes
+- **enabled/**: Symlinks to active components from available/ directories
+
+### Component Types
+
+1. **Aliases** (`aliases/available/`): Command shortcuts and convenience functions
+2. **Plugins** (`plugins/available/`): Extended functionality and integrations
+3. **Completions** (`completion/available/`): Tab completion definitions
+4. **Themes** (`themes/`): Prompt customizations and visual styles
+
+### Loading Order
+
+1. Libraries (except appearance)
+2. Global enabled directory
+3. Enabled aliases, plugins, completions
+4. Theme files (if BASH_IT_THEME is set)
+5. Custom files from BASH_IT_CUSTOM directory
+
+## Development Commands
+
+### Testing
+```bash
+# Run all tests using BATS (Bash Automated Testing System)
+test/run
+
+# Run specific test suites
+test/run test/bash_it test/completion test/plugins
+
+# Tests require git submodules to be initialized
+git submodule init && git submodule update
+```
+
+### Linting and Code Quality
+
+The project uses a gradual pre-commit system implementation via `clean_files.txt` allow-list:
+
+```bash
+# Run pre-commit hooks only on allow-listed clean files
+./lint_clean_files.sh
+
+# Run pre-commit hooks on all files (for testing new coverage)
+pre-commit run --all-files
+
+# Manual shellcheck on bash files
+shellcheck **/*.bash
+
+# Format shell scripts
+shfmt -w **/*.bash
+```
+
+**Gradual Linting System**:
+- `clean_files.txt`: Allow-list of files/directories that pass all linting rules
+- `lint_clean_files.sh`: Runs pre-commit hooks only on allow-listed files
+- When modifying files NOT in `clean_files.txt`, ensure they pass linting before adding them to the allow-list
+- Before creating a PR, add newly cleaned files to `clean_files.txt` to expand coverage
+- This system allows gradual improvement of code quality across the large codebase
+
+**Vendor Directory Policy**:
+- Files in `vendor/` are treated as immutable external dependencies
+- Pre-commit hooks exclude vendor files via `.pre-commit-config.yaml` global exclude pattern
+- `clean_files.txt` does not include vendor shell scripts, only `.gitattributes`
+- CI and local linting will skip vendor files entirely
+
+### Component Management
+```bash
+# Enable/disable components
+bash-it enable alias git
+bash-it enable plugin history
+bash-it enable completion docker
+
+# Show available components
+bash-it show aliases
+bash-it show plugins  
+bash-it show completions
+
+# Search components
+bash-it search docker
+```
+
+## Key Configuration
+
+### Environment Variables
+- `BASH_IT`: Base directory path
+- `BASH_IT_THEME`: Active theme name
+- `BASH_IT_CUSTOM`: Custom components directory
+- `BASH_IT_LOG_PREFIX`: Logging prefix for debug output
+
+### File Structure Conventions
+- Available components: `{type}/available/{name}.{type}.bash`
+- Enabled components: `{type}/enabled/{name}.{type}.bash` (symlinks)
+- Custom components: `custom/{name}.bash`
+- Themes: `themes/{name}/`
+
+## Development Guidelines
+
+### Component Development
+- Use composure metadata: `about`, `group`, `author`, `example`
+- Follow naming convention: `{name}.{type}.bash`
+- Test components before submitting
+- Components should be modular and not conflict with others
+
+### Testing Components
+- Each component type has dedicated test files in `test/`
+- Use BATS framework for shell script testing
+- Test files follow pattern: `{component}.bats`
+
+### Code Standards
+- Use shellcheck for linting
+- Follow existing code style in the repository
+- Add appropriate metadata using composure functions
+- Components should handle missing dependencies gracefully
