Built on macOS ScreenCaptureKit to grab screenshots and recordings at the window level, something ffmpeg can't do natively. You get precise app or window targeting, GIF conversion with two-pass palettes, before/after diffs, and evidence bundles ready to attach to a PR. The CLI ships with agent mode flags (JSON output, no prompts, field filtering) and covers edge cases like OCR extraction, VHS terminal recordings, and Remotion renders. Requires Screen Recording permission on first run. If you need to capture "just that window" or build visual test evidence without wrestling with display IDs, this does it. macOS only, Go install, works from the terminal or through Claude.
