DeepSeek Harness (DSH) plugin: dispatch work to DSH agents from Claude Code / Codex — native subagent progress, in-host worker sessions with per-tier presets, and a multimodal bridge that lends the text-only harness vision and image generation.
DSH plugin: paste an API key to add a provider. 21 curated presets (OpenAI-compatible + Anthropic Messages) with per-app de-duplication and a custom endpoint form.
DeepSeek Harness subagent provider: delegate reasoning to Tabbit-served models through a local gateway. Ships its own minimal preset, gateway management, and delegation guidance.
