Built this to solve it.</p> <p>It reads the API-reported token values from Cowork's local session logs (not file-size estimates), shows a floating widget that turns yellow/red as you approach your plan's limit, and auto-generates a handoff markdown doc — your recent messages, the file paths you were working with, task summary from the start of the session, and current context usage. Paste it into a fresh session and pick up where you left off.</p> <p>The project itself was built across many sessions using its own handoff docs to bridge them.</p> <p>Rust/Tauri, open source, ~zero idle CPU. Windows only for now.</p> <p><a href="https://github.com/wangyuanliang2009-max/ctx-guard" rel="noopener noreferrer">https://github.com/wangyuanliang2009-max/ctx-guard</a></p> claude opensource rust productivity
