pp-agent-capture
macOS screen capture, window recording, GIF conversion, and agent evidence bundles from the terminal. Built on ScreenCaptureKit for window-level targeting ffmpeg cannot do. Use when the user wants a screenshot of a specific window or app, a screen recording, a GIF conversion, a before/after diff, an evidence bundle for a PR, OCR text from a window, a terminal VHS recording, a Remotion render, or wants to watch a UI for changes. Requires macOS Screen Recording permission on first run.

See the repository agent guide, section "Generated artifacts: registry.json, cli-skills/". --> Agent Capture - Printing Press CLI Prerequisites: Install the CLI This skill drives the agent-capture-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: agent-capture-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Reach for this when the user wants: screenshot a specific window or app (screenshot, batch for multiple) record video of a window, app, display, or region (record) convert a recording to an optimized GIF (convert) do a full capture + record + GIF pipeline in one command (pipeline) diff against a baseline screenshot (diff) for before/after evidence bundle screenshots + recording + GIF as evidence for a PR or bug report (evidence) find the right window by fuzzy-matching its title (find) stitch multiple screenshots into an animated GIF (stitch) extract text from a window using macOS Vision OCR (ocr) record a terminal session via VHS tape files (vhs) render Remotion compositions to video or stills (remotion) monitor a UI by periodic screenshots (watch) save and replay capture configs (pr …
