# MAID Runner

A tool-agnostic validation framework and Python library for the Manifest-driven AI Development (MAID) methodology. MAID Runner validates that code artifacts align with declarative YAML manifests, ensuring architectural integrity in AI-assisted development. Integrates with [ArchSpec](https://archspec.dev) for spec-to-code pipelines.

## 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 three-stream validation:**
- **Acceptance (WHAT)**: Immutable tests from specifications define system behavior
- **Structural (SKELETON)**: AST-level verification that code matches manifest contracts
- **Unit (HOW)**: Implementation-level tests verify internal correctness

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

# 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              # Python only (core — no tree-sitter)
pip install maid-runner[all]         # All language support (TypeScript, Svelte)
pip install maid-runner[typescript]  # TypeScript/JS only
pip install maid-runner[watch]       # File watching for TDD mode
```

### Multi-Tool Support

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

## CLI Reference

| Command | Purpose | Key Options |
|---------|---------|-------------|
| `maid validate [manifest]` | Validate manifest against code | `--mode behavioral\|implementation`, `--no-chain`, `--coherence`, `--json`, `--watch`, `--watch-all` |
| `maid test` | Run validation commands from manifests | `--manifest <path>`, `--watch`, `--watch-all`, `--fail-fast`, `--json` |
| `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 graph` | Knowledge graph operations | `query`, `export`, `analyze` |
| `maid coherence` | Run coherence checks | `--checks`, `--exclude`, `--json` |
| `maid schema` | Display manifest JSON Schema | |
| `maid init` | Initialize MAID in project | `--tool claude\|cursor\|windsurf\|generic\|auto` |
| `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` = validation failure, `2` = usage error. Use `--quiet` for automation.

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

### Common Workflows

```bash
# Validate all manifests (chains enabled by default)
maid validate

# Validate a single manifest
maid validate manifests/add-auth.manifest.yaml

# Validate without chain merging
maid validate manifests/add-auth.manifest.yaml --no-chain

# Validate behavioral tests
maid validate manifests/add-auth.manifest.yaml --mode behavioral

# Validate with coherence checks
maid validate --coherence

# TDD watch mode (single manifest)
maid test --manifest manifests/add-auth.manifest.yaml --watch

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

# Run all validation commands
maid test

# JSON output for CI/CD
maid validate --json
```

### File Tracking

When validating with manifest chains (default), 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 (v2 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.

### Validation Modes

| Mode | Files | Behavior |
|------|-------|----------|
| **Strict** | `files.create` | Implementation must EXACTLY match declared artifacts |
| **Permissive** | `files.edit` | Implementation must CONTAIN declared artifacts |

### Artifact Kinds

**Common:** `class`, `function`, `method`, `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/`
3. Validate: `maid validate <manifest> --mode behavioral`
4. Iterate until validation passes

### Phase 3: Implementation Loop
1. Implement code per manifest
2. Validate: `maid validate <manifest>`
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

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)
```
