Peekaboo

Use for macOS screen capture, UI inspection, and GUI automation.

Binary

• Prefer ~/bin/peekaboo when present; it is Peter's local release copy.
• Else use peekaboo.
• Check first: ~/bin/peekaboo --version || peekaboo --version.

Mac app host

• Launch Peekaboo.app before live capture/automation; the CLI does not auto-launch it.
• The app owns TCC grants and serves ~/Library/Application Support/Peekaboo/bridge.sock.
• Installed app: open -a Peekaboo. Repo build: build the Apps/Mac/Peekaboo.xcodeproj Peekaboo scheme, then open the resulting Peekaboo.app.
• peekaboo daemon start is not an app launch; the daemon has separate permissions and daemon.sock.
• Verify peekaboo bridge status --verbose --json selects hostKind: gui; use --bridge-socket "$HOME/Library/Application Support/Peekaboo/bridge.sock" when deterministic app routing matters.

Safety

• Check permissions before capture/automation: peekaboo permissions status --json.
• Screenshot needs Screen Recording; clicks/typing/window control need Accessibility.
• On remote Macs, Screenshot may be blocked by missing Screen Recording while clicks/typing still work through Accessibility; continue with clicks or DOM automation when the target is otherwise knowable.
• Prefer --json for machine parsing and --no-remote when testing local TCC.
• Do not click/type/destructively automate unless user asked or target is a controlled test.

Common Commands

PB="${PEEKABOO_BIN:-$HOME/bin/peekaboo}"
[ -x "$PB" ] || PB="$(command -v peekaboo)"

"$PB" permissions status --json
open -a Peekaboo
"$PB" bridge status --verbose --json
"$PB" list screens --json
"$PB" list apps --json
"$PB" list windows --app Safari --json
"$PB" image --mode screen --screen-index 0 --path /tmp/screen.png --json --no-remote
"$PB" see --app frontmost --path /tmp/frontmost.png --json --annotate
"$PB" tools --json
"$PB" learn
"$PB" click --coords 100,100 --json
"$PB" type "text" --json

Workflow

1. Resolve PB as above and confirm version when install state matters.
2. For live UI work, launch Peekaboo.app; verify the GUI bridge and its permissions.
3. Run permissions status --json; if missing TCC, report exact missing grant.
4. For screenshots, use image; include --path, --json, and usually --no-remote only when deliberately testing caller-local TCC.
5. For element targeting, run see --json --annotate, then click by element id/snapshot.
6. For long-running/change-aware screen capture, use capture live; for video frame sampling, use capture video.
7. Use tools --json for command/tool discovery and learn when the full agent guide is useful.
8. Verify output files with sips -g pixelWidth -g pixelHeight <path> or view the image.
