dsh-synapse

If you've used DeepSeek Harness for complex conversations, you know the pain: follow-ups pile up and context turns into a tangled mess, branches are hard to locate, and related sessions are scattered across the workspace. dsh-synapse exists to fix exactly that. It organizes sessions, follow-ups, and branches from the same workspace into a browsable, draggable, zoomable map, letting you understand conversational structure spatially—while the native DSH session log remains the single source of truth. Synapse only projects events; it never alters the underlying data.

Its core capabilities center on visualization and real branching: cards connect according to DSH's native fork relationships, so no second history is invented; text you select in an answer can be carried directly into a new follow-up, with reusable prompt fragments editable; and switching between the map and native chat keeps your current context perfectly in sync. Best of all, it reuses the existing DSH Web Server—no second app or proxy system is launched. Canvas layout data lives separately in $DSH_HOME/synapse/, and removing it won't delete any DSH sessions.

This plugin is ideal for developers doing long-form research, comparing multiple solution paths, or running complex role-play scenarios on DeepSeek Harness. It turns linear chat logs into navigable mind maps. And because it never touches prompts, model requests, tool schemas, or provider routing, it's a low-risk enhancement for anyone who wants better session management without changing their existing workflow.
