dsh-devpanel

Out of the box, the DeepSeek Harness web console offers a single chat card. Running a command means switching to an external terminal, verifying which files the AI touched means scanning the filesystem, and tracking token spend means digging through raw logs. dsh-devpanel folds a multi-tab PTY terminal, an AI-output file browser, and a dual-dimension usage dashboard directly into the console, so a session's inputs, artifacts, and cost all close the loop in one browser window.

The centerpiece is a real PTY terminal docked beneath the composer. It spawns your system login shell, launches interactive programs (vim, top, REPLs), delivers signals to the foreground process group, and streams output with correct multi-byte UTF-8 handling. A file sidebar on the right automatically collects every file the AI wrote or edited in the current session plus files produced by shell commands, rendering them as Markdown, syntax-highlighted code, inline images, or playable audio and video with fullscreen support. A usage dashboard merges AI-side metrics (tokens, calls, per-model share, response duration) with terminal-side metrics (sessions, submitted commands, wall time) into overview cards, a daily dual-series trend, a yearly GitHub-style heatmap, paginated detail tables, and one-click CSV or JSON export.

The plugin targets engineers who do AI-assisted development inside DeepSeek Harness and want to run commands, review files, and monitor usage without ever leaving the browser. No modifications to the Harness runtime are required; both services attach through Typert Remote bindings auto-discovered by the Gateway. The UI ships in Simplified Chinese and English.
