What it does

Converts an arxiv paper into a minimal, citation-anchored Python implementation. Trigger when user runs /paper2code with an arxiv URL or paper ID, says "implement this paper", or pastes an arxiv link asking for implementation. Flags all ambiguities honestly. Never invents implementation details not stated in the paper.

paper2code, Orchestration

You are executing the paper2code skill. This file governs the high-level flow. Each stage dispatches to a detailed reasoning protocol in pipeline/. Do NOT skip stages. Do NOT combine stages. Execute them in order.

Parse arguments

Extract from the user's input:

  • ARXIV_ID: the arxiv paper ID (e.g., 2106.09685). Strip any URL prefix.
  • MODE: one of minimal (default), full, educational.
  • FRAMEWORK: one of pytorch (default), jax, numpy.

If the user provided a full URL like https://arxiv.org/abs/2106.09685, extract the ID 2106.09685. If the user provided a versioned ID like 2106.09685v2, keep the version.

Set up working directory

Create a temporary working directory: .paper2code_work/{ARXIV_ID}/ This is where intermediate artifacts go. The final output goes in the current directory under {paper_slug}/.

Install dependencies

Run via Bash:

pip install pymupdf4llm pdfplumber requests pyyaml

Execute pipeline

Stage 1, Paper Acquisition and Parsing

Read and follow: pipeline/01_paper_acquisition.md

Run the helper script to fetch and parse the paper:

python skills/paper2code/scripts/fetch_paper.py {ARXIV_ID} .paper2code_work/{ARXIV_ID}/

Then run structure extraction:

python skills/paper2code/scripts/extract_structure.py .paper2code_work/{ARXIV_ID}/paper_text.md .paper2code_work/{ARXIV_ID}/

Verify the outputs exist before proceeding. If extraction failed, follow the fallback protocol in pipeline/01_paper_acquisition.md.

The script also searches for official code repositories (in the paper text and on the arxiv page) and saves any found links to paper_metadata.json under the official_code key. Verify these links before relying on them, see Step 8 in pipeline/01_paper_acquisition.md.

Stage 2, Contribution Identification

Read and follow: pipeline/02_contribution_identification.md
