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.
Why this skill is useful
Adds specific commands and workflows for macOS screen capture and recording that the AI wouldn't reliably generate on its own.

What this skill does
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 (preset) Skip it on non-macOS hosts; the CLI uses ScreenCaptureKit (macOS only). On first run it will prompt for Screen Recording permission; the permissions command guides that flow. Argument Parsing Parse $ARGUMENTS: 1. Empty, help, or --help -> show agent-capture --help 2. Starts with install -> CLI installation (no MCP server ships today) 3. …
