# Toyota Way Pre-commit Hooks - PMCP SDK

This directory contains pre-commit hooks implementing Toyota Way quality standards based on the PAIML MCP Agent Toolkit style.

## Philosophy

Following Toyota manufacturing principles:

- **🏭 Jidoka (自働化)**: Stop the line when defects are detected
- **📈 Kaizen (改善)**: Continuous improvement through quality checks
- **👀 Genchi Genbutsu (現地現物)**: Go see the actual situation (zero SATD tolerance)

## Zero Tolerance Standards

- **No technical debt comments** (TODO, FIXME, HACK, XXX)
- **No unwrap() calls** in production code
- **Zero lint warnings** with comprehensive clippy analysis
- **Perfect formatting** with rustfmt
- **Security vulnerabilities = 0** via cargo audit
- **Documentation tests** must pass (ALWAYS requirement)
- **Version synchronization** between VERSION file and Cargo.toml

## Setup

### Quick Setup
```bash
make setup-full        # Complete Toyota Way development environment
```

### Manual Setup
```bash
make setup             # Install development tools
make setup-pre-commit  # Install pre-commit hooks only
```

## Usage

### Automatic (Recommended)
Pre-commit hooks run automatically on every `git commit` - embodying the Jidoka principle of stopping the line when issues are detected.

### Manual Execution
```bash
make pre-commit-all     # Run on all files
make pre-commit-staged  # Run on staged files only
make pre-commit-gate    # Run Toyota Way quality gate (fallback)
```

## Quality Gates

### Pre-commit Hooks Include:

1. **Standard Quality**:
   - Trailing whitespace removal
   - End-of-file fixing
   - YAML/TOML/JSON validation
   - Large file detection
   - Unix line ending enforcement

2. **Rust-specific (Zero Tolerance)**:
   - Code formatting (`cargo fmt --check`)
   - Comprehensive lint analysis (`clippy` with pedantic settings)
   - Compilation verification (`cargo check`)

3. **Toyota Way Enforcement**:
   - Zero SATD (Self-Admitted Technical Debt) tolerance
   - No `unwrap()` calls in production code
   - Documentation tests validation
   - Security vulnerability checks
   - Version file synchronization

### CLAUDE.md Compliance

The configuration matches all requirements from CLAUDE.md:

- ✅ Pre-commit hook automatically runs Toyota Way quality checks
- ✅ Format checking: `cargo fmt --check`
- ✅ Clippy analysis: Zero warnings allowed 
- ✅ Build verification: Must compile successfully
- ✅ Doctest validation: All doctests must pass
- ✅ Blocks commits until quality gates pass

## Architecture

The configuration uses:
- **Standard hooks** from `pre-commit/pre-commit-hooks`
- **Rust-specific hooks** from `doublify/pre-commit-rust` 
- **Local Toyota Way hooks** for custom quality enforcement
- **Advanced hooks** for line ending consistency

## Integration with Makefile

The pre-commit system integrates seamlessly with existing Makefile targets:

- `make setup-full` includes pre-commit setup
- `make pre-commit-all` runs hooks manually
- `make quality-gate` includes all pre-commit checks
- Fallback to manual checks when pre-commit isn't installed

## Fail-Fast Philosophy

Following Toyota Way principles:
- `fail_fast: true` on all hooks
- Production line stops immediately when defects are found
- Zero tolerance for quality violations
- Manual review required for all changes

## Continuous Improvement (Kaizen)

The system enables continuous improvement through:
- Comprehensive quality metrics collection
- Automatic identification of quality issues
- Integration with existing Toyota Way development workflow
- Feedback loops for quality enhancement

This implementation represents manufacturing-grade quality control applied to software development, ensuring zero defects reach the main branch.
