## 🌟 Overview

**ReproAgent** is an AI-driven framework built on [OpenAI Gymnasium](https://gymnasium.farama.org/) that automates the end-to-end reproduction of machine learning research papers. Given a PDF, it autonomously:

1. **Parses** the paper to extract title, metrics, datasets, and GitHub links
2. **Clones** the linked repository
3. **Sets up** the environment (conda/venv) and installs dependencies
4. **Runs** inference or training scripts
5. **Debugs** errors using real traceback analysis
6. **Tunes** hyperparameters to close the gap between reproduced and claimed results
7. **Compares** final metrics against the paper's claims

It supports both a **Simulation** mode (safe, no system changes) and a **Real Execution** mode (actually clones repos, creates envs, runs code on your machine).

---

## ✨ Features

| Feature | Description |
|---------|-------------|
| 📄 **PDF Parsing** | Extracts metadata using Groq LLM (llama-3.3-70b) with regex fallback |
| 🔗 **Repo Discovery** | Finds GitHub links from paper text, cleans trailing punctuation |
| 📦 **Smart Environment Setup** | Auto-detects `requirements.txt`, `environment.yml`, or `pyproject.toml` and creates the correct env (pip venv or conda) |
| 🧠 **Intelligent Entry Point** | Scans for `inference.py`, `eval.py`, `main.py`, `train.py`, or extracts scripts from README bash blocks |
| 🐛 **Real Error Debugging** | Captures actual `stderr` tracebacks and feeds them into the debugging pipeline |
| 🧪 **Hyperparameter Tuning** | Modifies learning rate, batch size, optimizer, and epochs to reproduce paper metrics |
| 📊 **Dynamic Metric Extraction** | Extracts the actual evaluation metric (FID, BLEU, accuracy, PSNR, etc.) from the paper — not hardcoded |
| 🖥️ **Gradio Web UI** | Beautiful web interface with live logs, state tracking, and result visualization |

## 🚀 Quick Start

### Prerequisites

- **Python** 3.10+
- **Git** (for real execution mode)
- **Conda** (optional, for repos that use `environment.yml`)
- A **Groq API key** (free at [console.groq.com](https://console.groq.com))

### Installation

```bash
# 1. Clone the repository
git clone https://github.com/your-username/ReproAgent.git
cd ReproAgent

# 2. Create a virtual environment
python -m venv venv

# Windows
.\venv\Scripts\activate

# macOS/Linux
source venv/bin/activate

# 3. Install dependencies
pip install -r requirements.txt

# 4. Set up environment variables
cp .env.example .env
# Edit .env and add your GROQ_API_KEY
```

### Run

```bash
# Launch the Gradio web interface
python server/app.py
```

The UI will be available at `http://localhost:7860` with a public share link.

---

## 💻 Usage

### Web Interface (Recommended)

1. Open the Gradio UI at `http://localhost:7860`
2. **Upload** a research paper PDF (or paste a URL)
3. Choose **Execution Mode**:
   - `Simulation` — Safe demo, no system changes
   - `Real Execution` — Actually clones repos and runs code
4. Set **Clone Directory** (where repos will be cloned, e.g. `D:\reproductions`)
5. Click **Start Reproduction** and watch the agent work in real-time

### Command Line

```bash
# Run validation to ensure everything works
python validate.py

# Run a quick inference test
python inference.py
```

### Programmatic API

```python
from reproagent.environment import ReproAgentEnv
from agents.reasoning_agent import create_agent

# Create environment
env = ReproAgentEnv(
    difficulty="easy",
    max_steps=100,
    use_llm=True,
    exec_mode="Real Execution",
    workspace_dir="./workspace"
)

# Create agent
agent = create_agent(env, agent_type="reasoning", use_llm=True)

# Run episode
obs, info = env.reset()
agent.reset()

for step in range(100):
    action = agent.select_action(obs, info)
    obs, reward, terminated, truncated, info = env.step(action)

    print(f"Step {step}: {info['action_type']} | reward={reward:.2f}")

    if terminated or truncated:
        break
```

## ⚙️ Configuration

### Environment Variables

Create a `.env` file from the template:

```bash
cp .env.example .env
```

| Variable | Required | Description |
|----------|----------|-------------|
| `GROQ_API_KEY` | **Yes** | Groq API key for LLM-powered extraction ([get one free](https://console.groq.com)) |
| `OPENAI_API_KEY` | No | OpenAI API key (alternative LLM backend) |
| `HF_TOKEN` | No | HuggingFace token for model downloads |
| `GITHUB_TOKEN` | No | GitHub API token for higher rate limits |

### Execution Modes

| Mode | What it does | Use case |
|------|-------------|----------|
| **Simulation** | Simulates all actions with mock state transitions | Safe demos, hackathons, testing |
| **Real Execution** | Runs `git clone`, `conda env create`, `pip install`, `python script.py` on your system | Actually reproducing papers |

---

## 🔄 How It Works

The agent follows a **phase-based state machine** with 7 phases:

```
PARSING → REPO_ANALYSIS → SETUP → EXECUTION → DEBUGGING → EXPERIMENTATION → COMPARISON
```

### Phase Details

| Phase | Actions | What Happens |
|-------|---------|--------------|
| **Parsing** | `PARSE_PDF`, `EXTRACT_GITHUB`, `EXTRACT_METRICS` | LLM reads paper, extracts title, GitHub URL, target metric (e.g., FID=7.5) |
| **Repo Analysis** | `CLONE_REPO`, `READ_README`, `FIND_ENTRY_POINT`, `EXTRACT_DEPS` | Clones repo, reads README, finds scripts from bash blocks, detects `environment.yml` |
| **Setup** | `CREATE_VENV`, `INSTALL_REQUIREMENTS`, `VERIFY_SETUP` | Creates conda/venv env, installs deps, verifies setup |
| **Execution** | `RUN_TRAINING`, `RUN_EVAL`, `CHECK_LOGS` | Runs the entry point script via subprocess, captures stdout/stderr |
| **Debugging** | `ANALYZE_ERROR`, `SEARCH_SOLUTION`, `APPLY_FIX` | Parses real Python tracebacks, proposes and applies fixes |
| **Experimentation** | `MODIFY_LR`, `MODIFY_BATCH`, `RUN_EXPERIMENT` | Tunes hyperparameters to close the metric gap |
| **Comparison** | `COMPARE_RESULTS`, `GENERATE_REPORT` | Compares reproduced metric vs. paper claim, generates summary |

### Reward Function

The environment provides a multi-component reward signal:

- **Phase progress** (+10 for advancing through phases)
- **Code execution** (+20 for successful script runs)
- **Error fixing** (+15 per resolved error)
- **Metric improvement** (scaled by how close the reproduced result is to the paper's claim)
- **Time penalty** (-0.01 per step to encourage efficiency)

---

## ✅ Validation

Run the full validation suite to confirm everything works:

```bash
python validate.py
```

This tests:

| Test | What it validates |
|------|-------------------|
| Environment | `ReproAgentEnv` creates, resets, steps correctly |
| Spaces | Observation and action spaces match the Gymnasium spec |
| Episodes | Full multi-step episodes run without crashes |
| Agents | `ReasoningAgent` and `RandomAgent` interact with the env |
| Demo | Gradio app imports successfully |
| Graders | Reproduction quality grader loads |
| OpenEnv | `openenv.yaml` is present and well-formed |

Expected output:

```
ENVIRONMENT          ✅ PASSED
AGENTS               ✅ PASSED
DEMO                 ✅ PASSED
GRADERS              ✅ PASSED
OPENENV_YAML         ✅ PASSED

🎉 ALL VALIDATIONS PASSED!
✅ System is ready for deployment
```

---

## 🐳 Docker Deployment

```bash
# Build the image
docker build -t reproagent .

# Run with your API key
docker run -p 7860:7860 -e GROQ_API_KEY=your_key_here reproagent
