# MAID Runner

[![PyPI version](https://badge.fury.io/py/maid-runner.svg)](https://badge.fury.io/py/maid-runner)
[![Python Version](https://img.shields.io/pypi/pyversions/maid-runner.svg)](https://pypi.org/project/maid-runner/)

A tool-agnostic validation framework for the Manifest-driven AI Development (MAID) methodology. MAID Runner validates that code artifacts align with their declarative manifests, ensuring architectural integrity in AI-assisted development.

📹 **[Watch the introductory video](https://youtu.be/0a9ys-F63fQ)**

## Why MAID Runner?

LLMs generate code based on statistical likelihood, optimizing for "plausibility" rather than architectural soundness. Without intervention, this leads to "AI Slop"—code that is syntactically valid but architecturally chaotic.

**MAID Runner enforces dual-constraint validation:**
- **Behavioral (Coordinate A)**: Code must pass the test suite
- **Structural (Coordinate B)**: Code must adhere to a pre-designed JSON manifest

This transforms AI from a "Junior Developer" requiring reactive code review into a "Stochastic Compiler" that translates rigid specifications into implementation details.

## Supported Languages

| Language | Extensions | Parser | Key Features |
|----------|------------|--------|--------------|
| **Python** | `.py` | AST (built-in) | Classes, functions, methods, attributes, type hints, async/await, decorators |
| **TypeScript/JS** | `.ts`, `.tsx`, `.js`, `.jsx` | tree-sitter | Classes, interfaces, type aliases, enums, namespaces, generics, JSX/TSX |
| **Svelte** | `.svelte` | tree-sitter | Components, props, exports, script blocks, reactive statements |

## Quick Start

```bash
# Install
pip install maid-runner  # or: uv pip install maid-runner

# Initialize MAID in your project
maid init

# Interactive guide
maid howto --section quickstart
```

## Installation

### Claude Code Plugin (Recommended)

```bash
/plugin marketplace add aidrivencoder/claude-plugins
/plugin install maid-runner@aidrivencoder
```

### From PyPI

```bash
pip install maid-runner      # or: uv pip install maid-runner
```

### Multi-Tool Support

```bash
maid init                    # Claude Code (default)
maid init --cursor           # Cursor IDE
maid init --windsurf         # Windsurf IDE
maid init --generic          # Generic MAID.md
maid init --all              # All tools
```

## CLI Reference

| Command | Purpose | Key Options |
|---------|---------|-------------|
| `maid validate <manifest>` | Validate manifest against code | `--validation-mode behavioral\|implementation`, `--use-manifest-chain`, `--watch`, `--watch-all` |
| `maid test` | Run validation commands from manifests | `--manifest <path>`, `--watch`, `--watch-all`, `--fail-fast` |
| `maid snapshot <file>` | Generate manifest from existing code | `--output-dir`, `--force` |
| `maid snapshot-system` | Aggregate all active manifests | `--output`, `--manifest-dir` |
| `maid manifests <file>` | List manifests referencing a file | `--manifest-dir`, `--quiet` |
| `maid files` | Show file tracking status | `--manifest-dir`, `--quiet` |
| `maid init` | Initialize MAID in project | `--claude`, `--cursor`, `--windsurf`, `--generic`, `--all` |
| `maid howto` | Interactive methodology guide | `--section intro\|principles\|workflow\|quickstart\|patterns\|commands\|troubleshooting` |
| `maid manifest create <file>` | Create manifest for a file | `--goal`, `--artifacts`, `--dry-run` |

**Exit codes:** `0` = success, `1` = failure. Use `--quiet` for automation.

Run `maid howto --section commands` for detailed usage and examples.

### Common Workflows

```bash
# Validate implementation (default mode)
maid validate manifests/task-013.manifest.json --use-manifest-chain

# Validate behavioral tests
maid validate manifests/task-013.manifest.json --validation-mode behavioral

# TDD watch mode (single manifest)
maid test --manifest manifests/task-013.manifest.json --watch

# Multi-manifest watch (entire codebase)
maid test --watch-all

# Run all validation commands
maid test
```

### File Tracking

When using `--use-manifest-chain`, MAID Runner reports file compliance status:

- **🔴 UNDECLARED**: Files not in any manifest (no audit trail)
- **🟡 REGISTERED**: Files tracked but incomplete (missing artifacts/tests)
- **✓ TRACKED**: Files with full MAID compliance

## Manifest Structure

```json
{
  "goal": "Implement email validation",
  "taskType": "create",
  "supersedes": [],
  "creatableFiles": ["validators/email_validator.py"],
  "editableFiles": [],
  "readonlyFiles": ["tests/test_email_validation.py"],
  "expectedArtifacts": {
    "file": "validators/email_validator.py",
    "contains": [
      {"type": "class", "name": "EmailValidator"},
      {
        "type": "function",
        "name": "validate",
        "class": "EmailValidator",
        "parameters": [{"name": "email", "type": "str"}],
        "returns": "bool"
      }
    ]
  },
  "validationCommand": ["pytest", "tests/test_email_validation.py", "-v"]
}
```

### Validation Modes

| Mode | Files | Behavior |
|------|-------|----------|
| **Strict** | `creatableFiles` | Implementation must EXACTLY match `expectedArtifacts` |
| **Permissive** | `editableFiles` | Implementation must CONTAIN `expectedArtifacts` |

### Artifact Types

**Common:** `class`, `function`, `attribute`

**TypeScript-specific:** `interface`, `type`, `enum`, `namespace`

## Development Workflow

### Phase 1: Goal Definition
Define the high-level feature or bug fix.

### Phase 2: Planning Loop
1. Create manifest: `maid manifest create <file> --goal "Description"`
2. Create behavioral tests in `tests/test_task_XXX_*.py`
3. Validate: `maid validate <manifest> --validation-mode behavioral`
4. Iterate until validation passes

### Phase 3: Implementation Loop
1. Implement code per manifest
2. Validate: `maid validate <manifest> --use-manifest-chain`
3. Run tests: `maid test --manifest <manifest>`
4. Iterate until all tests pass

### Phase 4: Integration
Verify complete chain: `maid validate` and `maid test` pass for all active manifests.

## Library API (v2)

MAID Runner provides a Python library API for direct integration with tools, CI/CD, and custom scripts.

### Basic Validation

```python
from maid_runner import validate, validate_all

# Validate a single manifest
result = validate("manifests/add-auth.manifest.yaml")
if result.success:
    print("All checks passed")
else:
    for error in result.errors:
        print(f"{error.code.value}: {error.message}")

# Validate all manifests in directory
batch = validate_all("manifests/")
print(f"{batch.passed}/{batch.total_manifests} passed")
```

### Manifest Chain Operations

```python
from maid_runner import ManifestChain

chain = ManifestChain("manifests/")

for m in chain.active_manifests():
    print(f"{m.slug}: {m.goal}")

artifacts = chain.merged_artifacts_for("src/auth/service.py")
```

### Loading and Saving Manifests

```python
from maid_runner import load_manifest, save_manifest

manifest = load_manifest("manifests/add-auth.manifest.yaml")  # YAML v2 or JSON v1
print(manifest.goal)
save_manifest(manifest, "manifests/copy.manifest.yaml")
```

### Snapshot Generation

```python
from maid_runner import generate_snapshot

manifest = generate_snapshot("src/auth/service.py")
print(f"Found {len(manifest.all_file_specs[0].artifacts)} artifacts")
```

### JSON Output for Tool Integration

```python
from maid_runner import validate

result = validate("manifests/add-auth.manifest.yaml")
print(result.to_json())  # Structured JSON output
```

### Custom Validator Registration

```python
from maid_runner import ValidatorRegistry, BaseValidator, CollectionResult

class GoValidator(BaseValidator):
    @classmethod
    def supported_extensions(cls):
        return (".go",)

    def collect_implementation_artifacts(self, source, file_path):
        return CollectionResult(artifacts=[], language="go", file_path=str(file_path))

    def collect_behavioral_artifacts(self, source, file_path):
        return CollectionResult(artifacts=[], language="go", file_path=str(file_path))

ValidatorRegistry.register(GoValidator)
```

## V2 Manifest Format (YAML)

```yaml
schema: "2"
goal: "Implement email validation"
type: feature
files:
  create:
    - path: validators/email_validator.py
      artifacts:
        - kind: class
          name: EmailValidator
        - kind: method
          name: validate
          of: EmailValidator
          args:
            - name: email
              type: str
          returns: bool
  read:
    - tests/test_email_validation.py
validate:
  - pytest tests/test_email_validation.py -v
```

V1 JSON manifests are auto-converted when loaded.
