Opens the official chat.deepseek.com web app inside DeepSeek Harness: one sidebar entry renders the real page in the center column through the desktop shell's native browser guest, and keeps you signed in across restarts. No chat UI, no agent tools, no runtime dependencies.
Per-agent model switching for DeepSeek Harness: set_model / list_models agent tools with provider whitelist and token-budget guardrails, plus plan-mode model staging and cache-safe active-model context.
DeepSeek Harness plugin for local image / voice / music / SFX generation: the same character stays the same character across calls, degenerate output is refused rather than returned, and the GPU is untouched when idle. Hand the image half to any OpenAI-shaped API instead and its engine and 10.1 GiB of weights are never installed.
DSH book-to-skill plugin: a 5-stage long task (fetch → parse → understand → generate → install) with 3 human gates, host tools for the agent and a browser timeline panel
AI audio generation plugin for the DeepSeek Harness web GUI: multi-vendor TTS, music, sound effects and voice design with a sidebar panel, model comparison, resource library and Agent tools.
