dsh-popout-sidebar

When you're running an agent inside DeepSeek Harness Web UI, it's easy to lose track of what it actually changed. Files written or edited by the agent, images generated by bash or pwsh commands, and the exact old/new snippets from every edit are scattered across logs, terminals, and folders. This plugin gathers all of that into one sidebar: artifacts created or modified via write/edit appear in a real-time list, alongside a lazy-loading file tree of the entire workspace that you can click through and preview instantly. Even better, the whole sidebar can pop out into a separate browser tab — drag it to a second monitor and inspect artifacts in full detail while the agent keeps working in the main window.

It's not just a file list, either. Code and plain text get syntax highlighting and line numbers, Markdown is rendered properly, images and PDFs open in the browser's native viewers, and HTML files preview inside a sandboxed iframe. Files changed by edit show a delete/add diff so you can see exactly what the agent modified, and overly long content is truncated to avoid freezing the UI. Each row lets you copy its path or drop a @path reference into the chat input for follow-up questions. A clear mode lets you mark artifacts with a red tint and remove them from the list. Everything — default expanded state, auto-refresh interval, file tree visibility, minimum panel width, preview area height — is configurable from the settings panel and persisted to localStorage.

This plugin is for anyone who works with Harness agents on a regular basis and wants to verify what the agent produced without digging through raw logs. Whether you're generating code, assembling documents, or having scripts batch-produce images and PDFs, it turns "what did the agent create?" into a glanceable list instead of a guessing game. Multi-monitor users will love the pop-out tab, and since it coexists with other sidebar plugins (it politely moves to the left of them), you never have to choose between tools.
