dsh-session-tree

Append-only, multi-branch conversation trees for DeepSeek-Harness — fork any historical node, clone a branch into a new session, and browse the whole lineage as one merged WebUI graph. Old history is never edited or deleted.

Three commands:

Command	What it does
/tree	Open the merged lineage graph: every non-subagent session and node, clickable and bindable
/fork	Branch from any historical node — the fork appears in the graph and as an inline menu under its source session
/clone	Duplicate the current conversation into an independent new session under the same project

Published as four npm packages under the @robiteame scope:

Package	Role
@robiteame/dsh-session-tree	Carrier Bundle: one install mounts everything below through its composition layer
@robiteame/dsh-pi-agent-session-tree	Host domain service: the SessionTree/SessionTreeStore domain model and the sessionTree Remote
@robiteame/dsh-tool-session-tree	Command surface: the /tree /fork /clone commands
@robiteame/dsh-client-ui-session-tree	WebUI tree panel: additive right-side overlay on official builds, native details dock on patched builds

Install (users)

One command — from the plugin market UI, or from a Harness checkout's CLI:

dsh plugin --profile <profile> add @robiteame/dsh-session-tree

Prebuilt tarballs install the same way and need no build scripts:

dsh plugin --profile <profile> add robiteame-dsh-session-tree-0.3.0.tgz

After installing, restart the profile. The composition gains three rows (pi-agent-session-tree, tool-session-tree, ui-session-tree) that load the Host service, the commands, and the browser panel. Verify the composed layer:

dsh --profile <profile> --dump-config   # should list the three session-tree rows

Requires DeepSeek-Harness 0.1.5-rc.2 (or a compatible 0.1.5 build) and Cordis ^4.0.2; the target installation provides those peers. No install scripts run — the tarballs ship prebuilt lib/ artifacts.

The three commands

/tree — open the tree panel

/tree opens the right-side panel as one merged graph for the current session's lineage: ancestors, forks, and clones appear in a single git-style view, with user messages, assistant replies, tool calls, and model switches shown as connected nodes. Shared copied prefixes are deduplicated, fork points carry session badges, and the current session's path stays highlighted. Click a node to bind it; clicking a node owned by another session opens that session first. Collapse individual subtrees or whole session branches to focus the graph.

/fork — branch from any historical node
