dsh-session-migrator

DeepSeek Harness stores full session logs, subagent records, and image attachments entirely on local disk. Switch machines and your accumulated context is stranded on the old one. dsh-session-migrator solves this: export a session on one device, drag the ZIP, JSONL, or complete export folder into Harness on another, and the entire migration completes visually through the sidebar interface without memorizing commands or editing paths manually.

Core capabilities include drag-and-drop import in multiple formats; automatic workspace path remapping to the destination device; reconstruction of the full session tree including the root and every subagent descendant; restoration of referenced PNG, JPEG, WebP, and GIF attachments with content-addressed ID verification; safe whole-tree cloning with unified ID and reference remapping when any session ID conflicts locally, never overwriting existing data; and pre-write validation through decodeStorageRecord and Session.create for Harness-native integrity.

It is suited to developers who switch between multiple machines, teams that need to hand off session context to a colleague, or anyone who simply wants to back up or relocate local session records.
