Show HN: Contrails – App to watch coding agents chats and save them to your repo (github.com)

Contrails, an open-source application for macOS, Windows, and Linux, has been introduced to help developers track and preserve their interactions with coding agents such as VS Code Copilot, Claude Code, and Cursor. By monitoring coding sessions in real-time, Contrails transforms coding chats into human-readable Markdown documents, which are then saved directly into project repositories. This functionality not only ensures that the reasoning behind bug fixes or feature implementations is documented, but also provides future references for similar tasks, enhancing productivity and contextual memory. The significance of Contrails lies in its ability to retain critical information that coding agents typically forget between sessions, thereby bridging the knowledge gap. Built using Wails v2 with technologies including Go and React, it offers features such as automatic project discovery, filesystem watching, and Markdown output. Notably, it protects user privacy with anonymous telemetry and even accommodates projects with multiple agents simultaneously. The app's architecture allows it to efficiently manage and parse various coding session formats, making it an essential tool for developers eager to document their AI-assisted coding journeys.
