What it does and how to use it

A skill that teaches Claude Code to do ai research tasks well. It is packaged knowledge the model uses whenever it is relevant.

  1. Install the skill (command above).
  2. In Claude Code, describe what you need - the skill turns on by itself when the context fits.
  3. No commands to memorize: you talk in plain language and the skill does the rest.

Install (Claude Code)

mkdir -p .claude/skills/matplotlib-matplotlib-23476 && curl -fsSL https://doutorai.pt/data/lib/skills__matplotlib-matplotlib-23476.md -o .claude/skills/matplotlib-matplotlib-23476/SKILL.md

Paste this command into the terminal, in your project folder, and the component installs automatically.

I need to analyze the problem based on the description. Looking at the traceback and hints, this is a matplotlib pickling issue. Let me understand the problem:

1. On M1 Macs (high-DPI displays), the MacOSX backend doubles the DPI when showing figures
2. When pickling a figure, this doubled DPI gets saved
3. When unpickling, the figure gets shown again, which doubles the (already doubled) DPI

The hint says "we handle high-dpi cases by doubling the dpi on the figure when we show it" and "We are saving the doubled dpi which when re-loaded is doubled again."

The fix needs to ensure that the ori
