Install Pixel
Pixel is a command-line tool: Gemini CLI 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 Gemini CLI’s files when ~/.gemini exists; the hook only where ~/.gemini/settings.json already exists. For Gemini CLI:
~/.gemini/settings.json~/.gemini/skills/pixel/SKILL.md
A per-prompt evidence brief through a BeforeAgent hook in ~/.gemini/settings.json, and the pixel skill in ~/.gemini/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: Gemini CLI keeps its native search, and Pixel’s commands stay available when you ask for them.
A changed settings.json is backed up to a timestamped .pixel-bak.* sibling. Your own formatting, hooks and keys stay: a re-run replaces only Pixel's earlier entry, and pixel setup --remove takes it out.
Check it
pixel doctor .It checks the binary, the daemon and this repository’s index, the parts Gemini CLI 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.
