Install Pixel
Pixel is a command-line tool: Devin 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 Devin, outside the per-repository guard below. pixel doctor judges only what pixel install writes.
Install the plugin
Add github.com/LivioGama/pixel as a Devin plugin.
The plugin never installs the pixel binary. The protocol it loads starts by checking for it (command -v pixel) and tells the agent to work without Pixel’s commands when it is missing.
Per repository
pixel install --repo .Adds an advisory guard to this repository only, and skips every global step. For Devin:
.devin/config.local.json
The guard steers the agent toward Pixel commands, for example with a notice before an untargeted read of a large source file, and never blocks a tool call. Every file that names this machine’s pixel binary goes into the clone’s .git/info/exclude, so a git add -A cannot publish it. Every per-repository file
Check it
pixel doctor .pixel doctor . reports the wiring of every agent as green, stale or missing, and names the command that repairs each finding. For Devin alone:
pixel doctor . --only repo.devin-hooksRemove it
pixel uninstall --repo . removes only this repository’s files.
Remove the plugin with Devin’s own plugin or extension command.
