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/sympy-sympy-17139 && curl -fsSL https://doutorai.pt/data/lib/skills__sympy-sympy-17139.md -o .claude/skills/sympy-sympy-17139/SKILL.md

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

Based on the issue, I need to analyze the SymPy code and generate a patch. The issue occurs in `fu.py` at line 504 where there's a comparison `if (rv.exp < 0) == True:` that fails when the exponent is a complex number like `I`.

Let me look at the traceback more carefully:

1. The issue is in `/sympy/simplify/fu.py` at line 504
2. The comparison `(rv.exp < 0)` fails when `rv.exp` is `I` (the imaginary unit)
3. This is because you cannot compare complex numbers with real numbers using `<` or `>`

The fix should check if the exponent is a real number before doing the comparison, or handle the ca
