Paper to Code

Convert a research paper into a complete, runnable code repository.

Input

• $0 — Paper PDF path, paper text, or paper URL

References

Workflow (from Paper2Code)

Stage 1: Planning

Four-turn conversation to create a comprehensive plan:

1. Overall Plan: Extract methodology, experiments, datasets, hyperparameters, evaluation metrics
2. Architecture Design: Generate file list, Mermaid classDiagram, sequenceDiagram
3. Task Breakdown: Logic analysis per file, dependency-ordered task list, required packages
4. Configuration: Extract training details into config.yaml

Stage 2: Analysis

For each file in the task list (dependency order):

1. Conduct detailed logic analysis
2. Map paper methodology to code structure
3. Reference the config.yaml for all settings
4. Follow the UML class diagram interfaces strictly

Stage 3: Coding

For each file in dependency order:

1. Generate code with access to all previously generated files
2. Follow the design's data structures and interfaces exactly
3. Reference config.yaml — never fabricate configuration values
4. Write complete code — no TODOs or placeholders

Stage 4: Debugging (if needed)

If execution fails:

1. Collect error messages
2. Identify root cause using SEARCH/REPLACE diff format
3. Apply minimal fixes preserving original intent
4. Re-run until successful

Output Structure

reproduced_code/
├── config.yaml        # Training configuration
├── main.py            # Entry point
├── model.py           # Model architecture
├── dataset_loader.py  # Data loading
├── trainer.py         # Training loop
├── evaluation.py      # Metrics and evaluation
├── reproduce.sh       # Run script
└── requirements.txt   # Dependencies

Key Constraints

• Dependency order: Each file is generated with access to all previously generated files
• Interface contracts: Mermaid diagrams serve as rigid interface definitions across all stages
• No fabrication: Only use configurations explicitly stated in the paper
• Complete code: Every function must be fully implemented

Rules

• Follow the paper's methodology exactly — do not invent improvements
• Generate code in dependency order (data loading → model → training → evaluation → main)
• Use config.yaml for all hyperparameters and settings
• Every class/method in UML diagram must exist in code
• Generate a reproduce.sh script for one-command execution
• If paper details are ambiguous, note them explicitly
