dsh-session-drafts

Cursor-style New Session for DeepSeek Harness (DSH): every click mints a fresh durable blank session — persisted in Session persistence before the first message is ever sent — so you can keep several empty chats open at once, exactly like Cursor's new-chat tabs.

The stock web shell reuses a workspace's single blank session (one empty chat per workspace, silently). This plugin removes that cap and adds a sidebar Drafts switcher to manage the empties.

What it does

1. Fresh drafts, never reuse. workspaces.startSession — the one service entry behind every New Session surface (sidebar button, workspace browser, agent preset) — is patched on the live WorkspaceRuntime instance to always call session.create (which persists the Session entity host-side) and open the result. The stock target policy is preserved: explicit workspace → current session's workspace → recent workspace; no workspace at all still clears into the pure New Session view.
2. Drafts switcher. The stock sidebar tree hides blank sessions other than the current one. An add-on sidebar.footer.action entry renders a Drafts (N) trigger above Settings with a popover that lists every blank draft (workspace label + age, newest first): click to switch, × to discard (workspace archive — the row hides, the session log remains), or mint another draft from the panel footer.
3. Zero core edits. Instance-level property shadowing guarded by a Symbol.for marker (idempotent across HMR), restored on plugin unload, falling back to the stock method on any synchronous failure. No harness files are modified.

Install

dsh plugin --profile web add link:/path/to/dsh-session-drafts
# or from a published copy:
dsh plugin --profile web add @ne-ilyxa/dsh-session-drafts

Then restart the DSH web host (a profile boot composes the client bundle into the boot graph; hot activation is not attempted by this plugin).

Release channels

• npm — @ne-ilyxa/dsh-session-drafts; published from CI via trusted publishing (OIDC): no stored tokens, no 2FA prompts. Pushing a v* tag runs release.yml: tests → prebuilt tarball attached to the GitHub Release → npm publish --provenance. The one-time setup is on npmjs.com: Account Settings → Publishing access → Add trusted publisher (repository ne-ilyxa/dsh-session-drafts, workflow release.yml, environment release).
• Prebuilt tarball — every GitHub Release carries dsh-session-drafts.tgz (built by prepack, installable without npm and without pnpm's allowBuilds build approval).

Keyboard shortcuts

Shortcut	Action
Ctrl+Alt+N	Mint a fresh draft from anywhere (works with zero drafts too)
Ctrl+Alt+D	Open / close the Drafts popover

Verify it works

1. Click New Session twice — two empty chats now coexist (watch the Drafts count go up; no reuse jump).
2. Open Drafts in the sidebar foot, switch between the empties, discard one with ×.
3. Host truth: each click produced a session.create — sessions survive a page refresh and the host restart.

Screenshots

Three New Session clicks on one workspace — three independent durable drafts (plus the initial one), no reuse:
