dsh-plan-switch 📋

A one-click enter/exit Plan mode button for the DSH web input bar (a quick-click shortcut for /plan) — a plugin for DeepSeek Harness (dsh) web.

Unofficial project: independently developed and maintained by a community member, not an official DeepSeek product.

Features

• One-click enter/exit Plan mode: a checklist icon button at the left end of the input tool row; clicking it runs the official /plan toggle command.
• Hides while Plan mode is active: the button hides itself and the official plan card takes over the status display — there is never a duplicated indicator.
• Pending-switch guard: while a /plan toggle is queued, the button is disabled (the same “switching” semantics as the official plan chip), so a stray click can’t reverse the switch.
• Live state: the button follows the plan state through the official projection, so changes from any entry point (/plan command, official chip, agent switching mid-run) are reflected in real time.

Install

Official bundle install (one line):

dsh plugin --profile web add "github:a903067276-rgb/dsh-plan-switch#main"

Restart dsh web after installing (bundle layers are composed at startup). Requires pnpm on PATH (dsh plugin forwards to pnpm).

Manual mount (fallback): see docs/install.md — symlink into ~/.dsh/profiles/web/node_modules/ plus a single entry in ~/.dsh/cordis.patch.yml, then restart.

Usage

A checklist icon button appears at the left end of the input tool row (official DSH design tokens, follows dark/light theme). Click it to enter plan mode — the same as typing /plan. While plan mode is active the button hides itself: the official plan card takes over the status display, so there is never a duplicated indicator; while a /plan toggle is pending the button is disabled, so a second click can’t reverse the switch.

Platform support

Requirements

• DSH web (run with dsh web)
• No host-side setup: the host half is a no-op — the whole plugin is a client-side button that runs the official /plan command, so nothing extra is required on any platform.

How it works

• Host (lib/index.js): no behavior — this is a pure UI plugin; the client half is discovered through the dsh.client declaration in package.json (exports["./client"]).
• Client (lib/client.js): registers the checklist icon button in the conversation.input.left seat using official DSW design tokens (follows dark/light theme); reads plan state live through useProjection("plan"); clicking executes the official /plan command via ctx.remote.commands.execute(sessionId, "/plan") — the whole flow stays on the official command chain.
• State handling: the effective plan state mirrors the official PlanChip algorithm (pending ? !active : active). While plan mode is active the button returns null (hidden — the official plan card owns the indicator, no duplicate); while a toggle is pending the button is disabled so a second click can’t reverse the switch; command failures turn the button error-colored with the message in its tooltip.

Notes

• Pure client-side: no host routes, no file writes, no stored data.
• Restart dsh web after installing or updating (bundle layers are composed at startup); client-side edits apply on a page refresh.

Development

• Source: lib/index.js (host side, no-op), lib/client.js (web injection)
• Workflow: edit locally → push to main → pnpm update to verify the install
