# ATDD

Acceptance Test Driven Development toolkit for structured planning and convention enforcement.

ATDD covers the full software lifecycle, not just code. It starts from a job to be done (e.g., user problem or goal), turns it into deterministic requirements, validates them with tests, and then drives implementation.

## Installation

### From PyPI

```bash
pip install atdd
```

### Upgrade

```bash
pip install --upgrade atdd
```

### Uninstall (Consumer Repos)

If you want to remove ATDD entirely:

1. Uninstall the package:
   ```bash
   python -m pip uninstall atdd
   ```
2. Manually delete ATDD artifacts in the repo:
   ```text
   atdd-sessions/
   .atdd/
   Managed blocks in CLAUDE.md, AGENTS.md, etc.
   ```

Uninstalling ATDD does not remove or revert any repo files.

### For Development

```bash
# Clone the repo
git clone https://github.com/afokapu/atdd.git
cd atdd

# Install in editable mode with dev dependencies
pip install -e ".[dev]"

# Verify installation
atdd --help
```

## Quick Start

```bash
atdd init                      # Initialize ATDD in your project
atdd gate                      # ⚠️ START EVERY SESSION WITH THIS
atdd new <task>                # Create a planning session
atdd sync                      # Sync rules to agent config files
atdd validate                  # Run all validators
```

> **⚠️ `atdd gate` is required.** 
> 🤖 Tell your agent: "Run `atdd gate` and follow ATDD rigorously." 
> Agents skip instruction files but can't ignore tool ou





tput. No gate = no ATDD guarantees.

## What It Does

ATDD provides:

1. **Session Management** - Structured planning documents with templates and tracking
2. **Convention Enforcement** - YAML-based conventions validated via pytest
3. **ATDD Lifecycle** - Planner → Tester → Coder phase gates
4. **Agent Config Sync** - Keep ATDD rules in sync across AI agent config files

## Commands

### Project Initialization

```bash
atdd init              # Create atdd-sessions/, .atdd/, and CLAUDE.md
atdd init --force      # Reinitialize (overwrites existing)
```

Creates:
```
your-project/
├── CLAUDE.md              # With managed ATDD block
├── atdd-sessions/
│   ├── SESSION-TEMPLATE.md
│   └── archive/
└── .atdd/
    ├── manifest.yaml      # Session tracking
    └── config.yaml        # Agent sync configuration
```

### Session Management

```bash
atdd new <slug>                         # Create new session
atdd new <slug> --type <type>           # Specify type
atdd session list                       # List all sessions
atdd session archive <id>               # Archive session
atdd session sync                       # Sync manifest with files
```

Session types: `implementation`, `migration`, `refactor`, `analysis`, `planning`, `cleanup`, `tracking`

### Agent Config Sync

Sync ATDD rules to agent config files using managed blocks that preserve user content:

```bash
atdd sync                  # Sync all enabled agents from config
atdd sync --agent claude   # Sync specific agent only
atdd sync --verify         # Check if files are in sync (for CI)
atdd sync --status         # Show sync status for all agents
```

Supported agents:
| Agent | File |
|-------|------|
| claude | CLAUDE.md |
| codex | AGENTS.md |
| gemini | GEMINI.md |
| qwen | QWEN.md |

Configure which agents to sync in `.atdd/config.yaml`:
```yaml
version: "1.0"
sync:
  agents:
    - claude      # Enabled by default
    # - codex     # Uncomment to sync AGENTS.md
    # - gemini    # Uncomment to sync GEMINI.md
    # - qwen      # Uncomment to sync QWEN.md
```

**Multi-agent setup:** To use multiple agents with consistent rules, enable them all in config and run sync:

```yaml
sync:
  agents:
    - claude
    - codex
    - gemini
    - qwen
```

```bash
atdd sync  # Creates/updates CLAUDE.md, AGENTS.md, GEMINI.md, QWEN.md
```

### ATDD Gate (Bootstrap Protocol)

Agents often skip instruction files. The gate solves this by injecting rules via mandatory tool output.

**Protocol:**

1. Run this command first:
   ```bash
   atdd gate
   ```

2. Agent must paste output and confirm:
   - Which file(s) were loaded
   - The reported hash
   - The key constraints

3. If files are missing/unsynced:
   ```bash
   atdd sync
   atdd gate  # Re-verify
   ```

**Example output:**
```
============================================================
ATDD Gate Verification
============================================================

Loaded files:
  - CLAUDE.md (hash: d04f897c6691dc13...)

Key constraints:
  1. No ad-hoc tests - follow ATDD conventions
  2. Domain layer NEVER imports from other layers
  3. Phase transitions require quality gates

------------------------------------------------------------
Before starting work, confirm you have loaded these rules.
------------------------------------------------------------
```

**Why this works:**
- Gate output is mandatory tool output - agent can't ignore it
- Proves which ATDD files were actually loaded
- Forces consistency across all agents

**Rule:** If ATDD rules matter, start with `atdd gate`. No gate = no guarantees.

### Validation

```bash
atdd validate              # Run all validators
atdd validate planner      # Planning validators only
atdd validate tester       # Testing validators only
atdd validate coder        # Implementation validators only
atdd validate --quick      # Fast smoke test
atdd validate --coverage   # With coverage report
atdd validate --html       # With HTML report
```

### Release Versioning

ATDD enforces release versioning via coach validators. Recommended: keep a single root `VERSION` file as the canonical source (first line like `1.2.3 - short summary`; trailing summary is ignored). Configure the version file and tag prefix in `.atdd/config.yaml`:

```yaml
release:
  version_file: "VERSION"  # recommended single source of truth
  tag_prefix: "v"
```

If you also publish with language-specific manifests (e.g., `pyproject.toml`, `package.json`), keep their version fields in sync with `VERSION`.

Validation (`atdd validate coach` or `atdd validate`) requires:
- Version file exists and contains a version
- Git tag on HEAD matches `{tag_prefix}{version}`

### URN Graph UI

Visualize URN traceability as an interactive graph with search, family filters, and node inspection.

```bash
pip install atdd[viz]
atdd urn viz                           # Launch on default port 8502
atdd urn viz --port 9000               # Custom port
atdd urn viz --root wagon:my-wagon     # Subgraph from root
atdd urn viz --family wagon --family feature  # Filter families
```

Default port is **8502** to avoid conflicts with consumer repo Streamlit apps on 8501.

### Other Commands

```bash
atdd status                    # Platform status
atdd inventory                 # Generate artifact inventory
atdd inventory --format json   # Inventory as JSON
atdd registry update           # Update all registries
atdd --help                    # Full help
```

## Development

### Setup

```bash
git clone https://github.com/afokapu/atdd.git
cd atdd
pip install -e ".[dev]"
```

### Run Tests

```bash
# All tests
pytest

# Specific phase
pytest src/atdd/planner/validators/

# With coverage
pytest --cov=atdd --cov-report=html
```

### Adding Validators

1. Create `src/atdd/{phase}/validators/test_{name}.py`
2. Write pytest test functions
3. Run `atdd validate {phase}`

Validators are auto-discovered by pytest.

### Adding Conventions

1. Create `src/atdd/{phase}/conventions/{name}.convention.yaml`
2. Reference in validators via `Path(__file__).parent.parent / "conventions" / "..."`

## Requirements

- Python 3.10+
