screen

A command for listing every display connected to a Mac, including its ID, position, size, scaling, and whether it is the main display.

In plain words
What is it for?
Use it to inspect connected monitors, map global click coordinates, and prepare browser-window screenshots and clicks when page elements cannot be addressed directly.
Why use it?
It provides the screen layout and coordinate details needed to target the right display during desktop automation, including high-resolution Retina screens.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

screen scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

peekaboo screen

screen list reports every connected display with its stable display ID, global logical bounds, scale factor, and primary state. Bare peekaboo screen defaults to screen list.

Examples

# Human-readable display inventory
peekaboo screen list

# Coordinate-mapping fields for automation
peekaboo screen list --json \
  | jq '.data.screens[] | {id: .displayID, bounds, scale: .scaleFactor, main: .isPrimary}'

bounds and position use the same upper-left-origin global logical coordinate space as click --global. Multiply dimensions by scaleFactor when comparing them with physical-pixel captures. A Retina display can therefore report logical bounds of 1944×1274, scale 2, and a 3888×2548 pixel capture.

For browser pages whose accessibility tree contains no actionable web descendants, pair this inventory with peekaboo window list --app <browser> --json, capture the selected exact window with peekaboo see --window-id <id> --no-elements --json, then use the fresh receipt:

peekaboo click --window-id "$WINDOW_ID" --snapshot "$SNAPSHOT_ID" --at x,y \
  --foreground --input-strategy synthOnly
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

screen is a command published in the GitHub repository openclaw/Peekaboo (5,098 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 325 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
