+## 🌟 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
+```
+
+Or deploy to **HuggingFace Spaces**:
+
+```bash
+pip install gradio
+gradio deploy
+```
+
+---
+
