PAI 3.0 installer does not update fish shell config

[michaelaye]

Summary

The PAI 3.0 installer correctly detects fish shell during installation but only updates ~/.zshrc with the new pai alias. It does not update the fish shell config at ~/.config/fish/config.fish.

Steps to Reproduce

1. Have fish shell as your default shell (the installer even detects this)
2. Run the PAI 3.0 installer
3. Open a new fish shell session
4. Run pai

Expected Behavior

The pai command works, pointing to ~/.claude/skills/PAI/Tools/pai.ts.

Actual Behavior

error: Module not found "/Users/<user>/.claude/skills/CORE/tools/PAI.ts"

The old PAI 2.x fish function (pointing to CORE/tools/PAI.ts) is still in place. The installer added the correct alias to ~/.zshrc but did not update the fish config.

What the Installer Should Do

When fish shell is detected, the installer should update ~/.config/fish/config.fish by either:

1. Adding/replacing the pai function:

   function pai
       bun ~/.claude/skills/PAI/Tools/pai.ts $argv
   end

2. Or using a fish abbreviation:

   abbr -a pai 'bun ~/.claude/skills/PAI/Tools/pai.ts'

Note: Fish shell uses function/end blocks or abbr, not bash-style alias commands.

Workaround

Manually edit ~/.config/fish/config.fish and replace the old function with the correct path.

Environment

• macOS (Darwin)
• Fish shell (detected by installer)
• PAI 3.0

Fixed in commit 95d65cc. The installer now writes a fish shell function to ~/.config/fish/config.fish when fish is detected (the .config/fish/ directory exists). It cleans up old PAI/CORE fish functions and adds the correct function pai ... end block. Thanks for the report! 🙏
