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

Content
Based on the issue description and hints provided, I have enough context to generate the fix. The problem is in `sympy/functions/elementary/complexes.py` in the `Abs.eval` method. The hints clearly explain:
1. The issue is around lines 616-621 where there's a conjugate check
2. The fix should add a check for `arg.is_extended_real` before computing the conjugate
3. The condition should also be changed from `if _arg != conj or _arg != -conj:` to `if _arg not in (conj, -conj):`
