Install Pixel
Pixel is a command-line tool: Devin runs the pixel binary, so install it first (macOS and Linux).
curl -fsSL https://github.com/Pixel-CLI/pixel/releases/latest/download/install.sh | shHow to read the script before it runs. It does not change any agent’s configuration.
What pixel setup writes
pixel setupRun it once, from anywhere; it writes Devin’s files when Devin's ~/.config/devin directory exists; the skill only when ~/.devin exists. For Devin:
~/.config/devin/config.json~/.devin/skills/pixel/SKILL.md
A per-prompt evidence brief through Devin's UserPromptSubmit hook, with task lifecycle hooks, and the pixel skill in ~/.devin/skills/pixel/; native tools stay unchanged.
Every pixel setup also writes ~/.pixel/setup-receipt.json and ~/.pixel/config.yaml and ~/.claude/skills/pixel/SKILL.md and ~/.config/opencode/skills/pixel/SKILL.md and ~/.gemini/skills/pixel/SKILL.md and ~/.pixel/plugins/cand-j-callers/ and ~/.pixel/plugins/cand-j-chain/ and ~/.pixel/plugins/cand-j-stop-cause/ and ~/.pixel/plugins/cand-k-code-sites/ and ~/.pixel/plugins/cand-k-commit-patch/ and ~/.pixel/plugins/config-registry/ and ~/.pixel/plugins/doc-sections/ and ~/.pixel/plugins/error-origin/ and ~/.pixel/plugins/flow-rank/ and ~/.pixel/plugins/history-fallback/ and ~/.pixel/plugins/name-files/ and ~/.pixel/plugins/overview-answer-evidence/ and ~/.pixel/plugins/rank-blocks/ and ~/.pixel/plugins/test-bodies/. No prompt, rules file or retrieval guard is written: Devin keeps its native search, and Pixel’s commands stay available when you ask for them.
Check it
pixel doctor .It checks the binary, the daemon and this repository’s index, the parts Devin relies on.
Remove it
pixel setup --removeIt removes everything pixel setup wrote, for every agent at once, and the binary at ~/.local/bin/pixel, where the install script puts it. A package manager removes its own copy: uninstall with the manager that owns it.
