dsh-sidechat-plugin

When working through long, multi-turn conversations in DeepSeek Harness, you will often want to pause and ask for clarification, verify a line of reasoning, or revisit a problem from a different angle. Piling these questions into the main session scrambles the transcript; a temporary overlay vanishes the moment you close it. dsh-sidechat-plugin elevates side-clarification to a first-class concern: every SideChat is a full DSH Session with its own conversation page, native model selector, and persistent transcript. Uninstall the plugin later and those sessions remain, readable as ordinary conversations.

The workflow centers on /side. At creation time you pick from nine Seed strategies, ranging from the most recent message (tail:1) to a model-generated task summary (task), a frozen turn (turn), or even a specific character range within a message (selection). The goal is minimal context injection, never a copy of reasoning traces, tool calls, or the full parent transcript. Once the conversation is done, /sidefold produces a structured Fold that you preview, edit, and commit, and the parent session receives it as a no-reply append. /sidecite lets you reference a particular assistant reply back into the parent side. Permissions follow either a read-only mode or an inheritance snapshot, with the Host recomputing every tool grant so that no browser-side value can escalate access. Lifecycle states (archive, restore, abandon, orphaned) keep the SideChat inventory orderly at all times, and /sideusage reports the actual token counts persisted by the provider, not estimates.

This plugin is built for researchers and engineers who run long reasoning chains, iterate over many turns, or need to clarify details frequently inside DeepSeek Harness. If you want every confirmation to stay out of the main thread while still folding the conclusion back cleanly, SideChat gives you a lightweight, persistent, and auditable side channel exactly for that purpose.
