What it does

Copyplot is an agent skill from franklee16/academic-research-skills. Analyze a supplied scientific-figure image (PNG, JPEG, TIFF, or a rasterized figure), identify its chart type and visual grammar, infer axes and styling, and deliver a close Python/Matplotlib or Seaborn reproduction with synthetic or digitized example data stored in an Excel workbook whenever practical. Use for requests to imitate, reverse-engineer, redraw, reproduce, or learn from a paper figure such as line, scatter, bar, histogram, box, violin, heatmap, contour, error-bar, multi-panel, or mixed scientific plots.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/figure-reconstruction-guide.md` and `references/workbook-spec.md`).

It sits in Data & Analytics, covering Data visualization. It works with Python, Matplotlib, Seaborn and Microsoft Excel. The repository describes itself as: Comprehensive collection of Claude Code skills for academic research in economics, finance, and social sciences.

When your agent uses it

  • Requests to imitate
  • Reverse-engineer
  • Learn from a paper figure such as line
  • Mixed scientific plots

Example prompts

  • “/copyplot”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Inspect the source
  2. Classify the visual grammar
  3. Recover or synthesize data
  4. Write the reproduction script
  5. Render and compare
  6. Validate the package

What it can do on your machine

Read from SKILL.md and the folder at commit 9a4b2db. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Copyplot loads about 1.8k tokens when it runs, and up to ~3.8k if it reads all its reference files. Until then it costs about 132 tokens; SKILL.md has 835 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~132
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 835 words (~1,818 tokens).

“Reconstruct a scientific figure as an editable, reproducible plotting project. Treat visual fidelity and scientific honesty as separate requirements: match the appearance closely, but never present inferred data as the source paper's original observations.”

How do I install Copyplot in Claude Code?

Run `npx skills add franklee16/academic-research-skills --skill copyplot -a claude-code`. Or copy the skill folder (visualization/copyplot in franklee16/academic-research-skills) into .claude/skills/copyplot in your project. Claude Code loads it when a task matches its description.

How do I install Copyplot in Codex?

Run `npx skills add franklee16/academic-research-skills --skill copyplot -a codex`. Or copy the skill folder (visualization/copyplot in franklee16/academic-research-skills) into .agents/skills/copyplot in your project. Codex loads it when a task matches its description.

Can I use Copyplot in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add franklee16/academic-research-skills --skill copyplot -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/copyplot, .gemini/skills/copyplot, .github/skills/copyplot and .opencode/skills/copyplot in your project.

What does Copyplot need to run?

Going by SKILL.md and its folder, Copyplot needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.

Does Copyplot access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Copyplot safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Copyplot use?

No licence was found for Copyplot or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Copyplot use?

About 1.8k tokens (SKILL.md is roughly 7.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2k tokens, read only when the agent opens those files.

What are the alternatives to Copyplot?
