Install Pixel
Pixel is a command-line tool: Windsurf runs the pixel binary, so install it first (macOS and Linux).
brew install LivioGama/tap/pixelThe install script is the other channel. Neither one changes any agent’s configuration.
What pixel install writes
Nothing for Windsurf. pixel doctor judges only what pixel install writes, so it does not see Windsurf’s rule.
Add the rule
Copy the rule the repository ships into your project:
mkdir -p .windsurf/rules
curl -fsSL https://raw.githubusercontent.com/LivioGama/pixel/main/.windsurf/rules/pixel.md -o .windsurf/rules/pixel.mdThe rule is the protocol: which pixel command replaces grep, a whole-file read or git log, and when a native tool is still right. It starts by checking for the binary (command -v pixel).
Check it
pixel doctor .It checks the binary, the daemon and this repository’s index, the parts Windsurf relies on once the rule is in place.
Remove it
Delete .windsurf/rules/pixel.md.
