At a glance

  • Works in 5 steps: Extract or derive plottable data from… → If the Emacs foreground color is not… → Write a gnuplot script to a temporary… → …
  • Invokes /gnuplot to plot data from the current context using gnuplot and output the resulting image path

What it does

Gnuplot is an agent skill from xenodium/emacs-skills. This skill should be used when the user invokes "/gnuplot" to plot data from the current context using gnuplot and output the resulting image path.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Emacs skills for coding agents.

When your agent uses it

  • Invokes /gnuplot to plot data from the current context using gnuplot and output the resulting image path

Example prompts

  • “/gnuplot”
  • “/gnuplot”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Extract or derive plottable data from the current context.
  2. If the Emacs foreground color is not already known from a previous plot in this session, query it
  3. Write a gnuplot script to a temporary file using that color.
  4. Run gnuplot on the script.
  5. Output the result as a markdown image on its own line

What it can do on your machine

Read from SKILL.md and the folder at commit a158238. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and gnuplot).

    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

Gnuplot loads about 734 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 328 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~734

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); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 328 words (~734 tokens).

“Plot data from the most recent interaction context using gnuplot. Generate a PNG image with a transparent background and output it as a markdown image so it renders inline.”
