codex-panel-reproduce

codex-panel-reproduce is a skill for Claude Code, Codex from littlepeachs/NaturePanelForge. It costs 56 tokens per session (1,141 once invoked), scanned A, original, MIT.

A workflow for recreating one scientific chart or figure panel as editable Python code using Matplotlib. It covers turning a supplied image into a script and rendered PNG and PDF files, with optional source information.

In plain words
What is it for?
Use it to reproduce or refine a single panel from a scientific paper, presentation, or other figure as code and exported image files.
Why use it?
It helps make a figure editable and reproducible instead of leaving it as a fixed image. The workflow also defines how to review and refine the generated result.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

codex-panel-reproduce scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Codex Panel Reproduce

Trigger

Use this for code-only reproduction or refinement of one scientific figure panel in NaturePanelForge. The target is an editable Python script plus rendered PNG/PDF, not image editing or raster tracing.

For local user-supplied images, do not run Qwen scoring and do not require Qwen outputs. Qwen context is only optional metadata when the input already comes from an existing SciFigureHub/NaturePanelForge pipeline directory.

Inputs

  • Single-image workflow: a target panel image path, optional caption, optional source PDF.
  • Existing-panel workflow: a panel directory containing target.png; optional metadata.json, qwen_score.json, qwen_prompt.md, and raw_response.txt. Missing Qwen files are acceptable for user-supplied images.
  • Refine workflow: an existing panel directory containing target.png, reproduce_panel.py, reproduce_panel.png, and reproduce_panel.pdf.

Reproduce One Panel

Run from the NaturePanelForge repo root:

python3 forge.py single-panel-image \
  --image path/to/target_panel.png \
  --out-root UserRuns/single_panel \
  --panel-id my_panel \
  --caption "brief visual/caption context" \
  --chart-type user_supplied \
  --review-rounds 4 \
  --skip-existing

This command prepares the local single-image bundle itself. It writes placeholder user-image metadata as needed; it does not classify the image with Qwen and does not need a local Qwen model.

For an existing panel directory:

python3 examples/prompt_codex_reproduce_fig02_g.py \
  --panel-dir path/to/panel_dir \
  --panel-root path/to/panel_root \
  --reviews-dir path/to/reviews_root \
  --specs-dir path/to/specs_root \
  --jobs 1 \
  --review-rounds 4 \
  --skip-existing

Expected panel outputs:

  • reproduce_panel.py
  • reproduce_panel.png
  • reproduce_panel.pdf

Expected mirrored review/spec outputs:

  • reproduce_panel_run_log.md
  • reproduce_panel_review_notes.md
  • reproduce_panel_review_summary.json
  • reproduce_panel_prompt.md
  • reproduce_panel_raw_response.txt

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
