Volcengine Ark Managed Agents plugin for DeepSeek Harness (DSH): a Managed Agents settings tab plus tools to dispatch tasks to Ark cloud Managed Agents and retrieve their trajectory, result, and artifacts.
Multi-agent collaboration suite for DeepSeek Harness: a user-configured specialist roster with on-demand dispatch (team_call / roundtable), model comparison, and a multimodal vision bridge — models come from the official provider flow, no bundled adapters.
Persistent global fetch proxy for DeepSeek Harness LLM requests (undici setGlobalDispatcher + EnvHttpProxyAgent), configured via the llm-proxy settings namespace
File-diff visualization between checkpoint time nodes for DeepSeek Harness: a read-only timeline + per-file line diff over the dsh-checkpoint-rewind checkpoints storage domain, with preview-first rollback (restore workspace files from any time node, single-file or whole-node; per-file current→snapshot preview diff; single-shot in-process undo), exposed as /diff and /rollback commands, a JSON HTTP API, and a GUI panel (session header action + shell overlay). Requires the upstream dsh-checkpoint-rewind plugin (the snapshot producer) to be installed first — without it, only the Trace scope works
