A Plan / Build mode switcher for DeepSeek Harness (dsh), shaped like opencode's Build/Plan selector.
Two things it adds:
完全权限 / Full access). It is always visible and switches the current session both ways.DSH 0.2.0-rc.2 already ships Plan mode (@deepseek-ai/dsh-plan-mode), but the official composer chip PlanChip is exit-only:
if (!(plan.pending ? !plan.active : plan.active)) return null;
When the session is not in Plan mode the chip renders nothing at all, so the only way into Plan mode is typing /plan by hand — there is no discoverable entry point. This plugin takes the same seat (conversation.input.plan) and supplies a two-way dropdown instead.
Build or Plan) with a chevron./plan off)/plan)--dsw-alias-state-business-* tokens).pending), the button already shows the target mode.Build / Plan as the starting mode for new sessions. The current session is unaffected; use the composer control for that.Pin the version, so pnpm's release cooldown cannot hand you an older build:
dsh plugin --profile web add dsh-plan-build-mode@1.1.0
Straight from GitHub (no npm publish needed):
dsh plugin --profile web add github:yzhclcl/dsh-plan-build-mode
Desktop app: install from the in-app Plugins page. The CLI cannot modify profiles/desktop.
Then fully quit and restart the process serving the profile. The client bundle revision is derived from file metadata (mtime/ctime/size), so a page refresh alone is not enough — a stale revision makes the browser request a URL the server now 404s, which surfaces as client-modules: bundle script ... failed to load.
Composer dropdown — click it, pick Build or Plan. It maps to the shipped /plan and /plan off commands, so nothing about the plan-mode machinery changes.
Default mode — Settings → General → Default mode, under the permission row.
Note: the first time you save this row,
~/.dsh/profiles/<profile>/cordis.patch.ymlgains a top-level entry at the end:- id: plan-build-mode name: dsh-plan-build-mode config: defaultMode: planThat is the normal
config-editorwrite path. Delete the entry (or setbuild) to go back to the default.
| Concern | Approach |
|---|---|
| Composer seat | conversation.input.plan — the modes row of the input bar, adjacent to conversation.input.permission |
| Shadowing the official chip | register({ priority: -1 }) — a single slot only rejects equal priority; the lowest priority renders |
| Reading state | useProjection("plan") → { active, pending } |
| Switching | ctx.remote.commands.execute(sessionId, "/plan" | "/plan off", []) |
| Styles | deduplicated injection via style[data-plugin-css="dsh-plan-build-mode"], reusing official size/colour tokens |
| Settings row seat | settings.general.item list slot, id: "default-mode", order: -10 (permission is -20, language is 0) |
| Settings read/write | ctx.configForms.get("plan-build-mode") → remote.settings.mutate(ns, [{op:"set",path:["defaultMode"],value}], revision) |
| Config field | z.union([z.const("build"), z.const("plan")]).default("build").volatile() — only entries carrying volatile fields reach the settings surface |
| Suppressing the auto form | ctx.inject(["settings"], (child) => child.effect(() => child.settings.configure({ auto: false }, ctx.fiber))) |
| Pinning new sessions | On session/created, if the session is brand new (seq === 0, not seeded, no parentSession) and the default is plan, append plan/mode { active: true } — the same first-party event @deepseek-ai/dsh-plan-mode writes, and one of the names on the persisted event allowlist |
Plan mode is a soft, prompt-level guide, not a sandbox. All tools stay available in both modes; the harness injects a plan:policy prompt section that tells the model to explore and plan rather than execute. Real restriction comes from the permission presets (sandbox mode + approval policy), which are independent and read no plan state. If you want a hard read-only guarantee, switch the permission preset to Read Only.
Switching mid-turn is supported: the intent is queued and applied at the next turn boundary, while the button immediately reflects the target.
| dsh | Status |
|---|---|
0.2.0-rc.2 | Verified on Windows, web profile — dropdown, settings row, persistence, and new-session pinning all exercised |
Declared range: >=0.2.0-0 <0.3.0-0. The plugin targets the 0.2.x seat layout (conversation.input.plan, settings.general.item) and the plan/mode event, so older 0.1.x hosts are out of scope.
dsh plugin --profile web remove dsh-plan-build-mode
Restart afterwards. The official PlanChip returns to its original behaviour immediately — this plugin modifies no official file.
