Developer Kit Langton's open-source macOS tool Scrawl (Rust, MIT, 680 stars) is being called the best productivity unlock in months for anyone running an agent → human feedback → agent loop.
- Press ⌥⇧S to start recording; talk, click around, and draw marks on screen, then press again to stop
- Packs screen recording, voice, and annotations into a compact bundle: an annotated contact sheet plus full-resolution keyframes, ready to feed into coding agents like Claude Code
- Core idea: show an agent the problem instead of describing it; ships with a skills/scrawl skill for integration
