dsh-save-money

Save-money plugin for DSH (DeepSeek Harness) — define your own "pause / resume" time windows; at pause time running long tasks are paused (not stopped) automatically, and they resume when the window ends. Built for LLM API peak/off-peak pricing (e.g. DeepSeek peak hours 9:00–12:00, 14:00–18:00 Beijing time, off-peak at half price), and equally useful for time-of-use electricity rates, bandwidth off-peak shifting, or any "I don't want the machine working during this period" scenario.

Status: ✅ Implemented, continuously maintained. 中文版

Interface

The colored status text in the top-right of the session header (Save · ⚪/🟢/🟡/🔴, color follows the state) is the single persistent entry — click it to open the settings popover. When a pause is upcoming or active, a reminder banner appears at the top of the page (with the End this save mode button).

Features

• Multiple time windows: add / remove pause-resume windows freely; supports midnight-crossing windows (23:00–08:00) and per-weekday filtering;
• Automatic pause on schedule: when the pause time arrives, running tasks are safely "frozen" (their progress is preserved exactly — nothing is interrupted or lost) and resume automatically when the window ends; if nothing is running, nothing is paused;
• No requests during the window (the saving core): inside a pause window the AI sends no new requests to the model service, so no cost is incurred; after the window ends (or on disable / end-this-window) everything resumes, with conversation context and in-flight tasks unaffected. The AI not replying inside a window (including new conversations) is expected — to resume right away, click the End this save mode button (takes effect directly, no AI involved);
• End this save mode (one-shot, current window only): the banner and settings-popover button end the currently active pause window only — if paused, tasks resume immediately and the gate opens; if a pause is upcoming, it is cancelled. The window is skipped until its resume time, then the state clears automatically. The next window (today or later) still takes effect, and the persistent Enable flag is never touched, so you cannot accidentally leave the feature disabled;
• UI reminders: top floating banner (light yellow for upcoming pause / light red for paused, with the End this save mode button) + the single persistent session-header entry (next to the Session log, "Save · 🟢 Working" colored status text; click to expand settings), colors follow the state in real time;
• Timezone support: IANA timezone dropdown, browser auto-detection with Beijing time (+8) fallback; UTC projection checked (Beijing 09:00 == UTC 01:00);
• One-click DeepSeek preset: dedupe-append the peak windows (08:58–12:02, 13:58–18:02, with a 2-minute boundary margin — pause 2 min early, resume 2 min late); it does not auto-enable — your call; legacy no-margin windows are upgraded automatically on one-click;
• Persistent config: all settings are saved automatically to the workspace file save-money.config.json (gitignored); configuration survives browser refresh and plugin disable/re-activate, and is loaded on startup with optional reconciliation of paused goals;
• Account balance display (optional): tick "Show balance" in settings and your official DeepSeek account balance appears next to the status text in the header (automatic currency symbol, theme-adaptive color). Off by default; shown only while the current model points at the official DeepSeek API;
• Spend statistics: with the balance display enabled, the backend samples the balance every 5 minutes (288 points covering the last 24 hours). Hover the balance to see how much was spent in the last 1 hour / 10 minutes / 24 hours (balance increases from top-ups or refunds show as "+amount");
• Non-intrusive by design: no screen lock, no overlay blocking, no user action prevented — only the automatic continuation of goals is paused; manual interaction always flows.

How it works

stateDiagram-v2
    direction TB
    [*] --> Disabled

    Disabled : Disabled ⚪ — nothing pauses, no money saved
    Working : Working 🟢 — normal use, requests flow
    Pausing : Pausing soon 🟡 — yellow banner reminder
    Paused : Paused 🔴 — requests suspended, no cost

    Disabled --> Working : check "Enable"
    Working --> Pausing : a window starts within 5 minutes
    Pausing --> Paused : pause time reached
    Paused --> Working : window ends, auto-resumes
    Paused --> Working : "End this save mode" — resume now
    Pausing --> Working : "End this save mode" — cancel this pause
    Working --> Disabled : uncheck "Enable"
    Pausing --> Disabled : uncheck "Enable"
    Paused --> Disabled : uncheck "Enable"

• When a pause window starts, running tasks are frozen (progress preserved) and the AI stops replying — that is normal: the machine is saving you money. Everything resumes automatically when the window ends;
• See the yellow "pause in X min" banner but don't want to pause right now? Click End this save mode to cancel this window only;
• Paused and want to continue immediately? Click End this save mode (red button) — it resumes right away, skips only the current window, and never turns off Enable: the next window (today or later) still saves money as usual. If you ever want every window to take effect again, uncheck and re-check Enable.

Install

The official DSH plugin form is a module exporting apply + cordis.yml mounting (see the DSH official tutorial). This repository offers three install options: two official paths (--patch quick try, distributable bundle) plus a development workflow (link + HMR hot reload). The official forms include the full plugin: Host logic (scheduling, gate, goal freeze, tools, HTTP endpoints) and the browser UI (status text, banner, settings page), which loads automatically — no AI-assisted setup needed.

Quick install (copy-paste)

Using ~/app/ as an example directory (each step assumes the previous one succeeded):

cd ~/app/

git clone https://github.com/zhu168/dsh-save-money.git

cd dsh-save-money
npm install

cd plugin
npm pack                    # runs the build automatically; produces the plugin tarball

ls                          # check the tarball name, e.g. dsh-save-money-1.3.2.tgz

cd ~/app/deepseek-harness   # change to your harness directory (clone it first if missing — see "0." below)

pnpm dsh plugin --profile web remove dsh-save-money   # only if you installed it before; skip if you haven't

pnpm dsh plugin --profile web add ../dsh-save-money/plugin/dsh-save-money-1.3.2.tgz   # use the name from `ls` above

pnpm dsh --profile web      # starts DeepSeek Harness — the plugin appears top-right in the session header

Two notes: ① the tarball name on the add line must match what ls printed (1.3.0 is just an example); ② if your harness runs via npx, replace every pnpm dsh above with npx @deepseek-ai/dsh (install commands too).

0. Run DSH itself first

The plugin runs inside DSH, so DSH must run before anything below. Two ways:

A. Installed CLI (easiest, needs Node.js):

npx @deepseek-ai/dsh web        # starts the Web UI at http://127.0.0.1:3080

B. From source (e.g. on a Raspberry Pi; dsh is NOT a global command — you must run pnpm dsh inside the checked-out deepseek-harness directory):

git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web                    # inside this directory only

In source mode, never type bare dsh ... — it is not on PATH (command not found: dsh). Use pnpm dsh ... from the deepseek-harness directory, or ./node_modules/.bin/dsh ....

Path 1: --patch quick try (official, loads local source)

Good for trying the plugin on the same machine where you keep this repository.

1. (Optional) Rebuild the latest plugin module — a fresh clone needs the build deps first:

   npm install          # first clone: installs typescript and friends
   npm run prepare      # one step: src/*.ts -> dist/*.js -> plugin/index.js + plugin/client.js
   

2. Edit cordis.patch.yml, replacing <REPO_ROOT> with the repository's absolute path (it is the only placeholder in the file — use your editor's "replace all"):

   - insert:
       - id: save-money
         name: '<REPO_ROOT>/plugin/index.js'
   

   Examples — Windows: name: 'D:/git/github/dsh-save-money/plugin/index.js'; Linux / macOS / Pi: name: '/home/pi/dsh-save-money/plugin/index.js'.

   If your profile already has the plugin installed via bundle / link, skip Path 1 (stacking --patch would register the plugin twice).

3. Start with the overlay:

   dsh web --patch ./cordis.patch.yml               # globally installed dsh
   npx @deepseek-ai/dsh web --patch ./cordis.patch.yml  # npx-launched (Step 0, option A)
   # from source: pnpm dsh web --patch ./cordis.patch.yml
   

4. Open the browser at the printed URL (default http://127.0.0.1:3080) — the "Save" status text appears in the session header top-right. No extra step needed.

Path 2: bundle + dsh plugin add (official, distributable — recommended for another machine / the Pi)

The bundle is a small .tgz that you build once and install anywhere. You do not clone this repository on the target machine — DSH installs the plugin into its own profile (~/.dsh/profiles/web/node_modules/).

Step 1 — build & pack the bundle (on any machine with this repository):

cd dsh-save-money
npm install             # first clone only (typescript dev dependency)
cd plugin
npm pack                # runs the prepare build automatically; produces dsh-save-money-1.3.2.tgz

plugin/ is the standard bundle layout: package.json declares dsh.bundle.patch + dsh.client, cordis.patch.yml inserts the plugin row, index.js is the Host module and client.js the browser UI bundle.

Step 2 — copy the tgz to the target machine (scp / USB stick / however you move files; run this on the build machine, one directory above the repository, adjusting the path to yours):

scp dsh-save-money/plugin/dsh-save-money-1.3.2.tgz pi@<pi-ip>:~/

Step 3 — install into a profile (on the target machine; first run initializes the profile with @deepseek-ai/dsh-base):

# DSH run from source (inside the deepseek-harness directory):
pnpm dsh plugin --profile web add ~/dsh-save-money-1.3.2.tgz
# npx-launched (Step 0, option A) or globally installed dsh: works from any directory
npx @deepseek-ai/dsh plugin --profile web add ~/dsh-save-money-1.3.2.tgz

Both commands do the same thing: install the tgz into ~/.dsh/profiles/web/node_modules/. Use whichever matches how you start DSH.

Git install also works: dsh plugin --profile web add github:you/dsh-save-money#<sha> (git install requires prepare builds and allowBuilds, see the DSH publish tutorial).

Step 4 — verify the layer mounted, then start (fully restart DSH, don't just refresh the page):

pnpm dsh --profile web --dump-config   # the output should show a dsh-save-money layer (its plugin rows)
pnpm dsh --profile web                 # Ctrl+C to stop an already-running instance first

Step 5 — open the browser at http://127.0.0.1:3080 and hard-refresh (Ctrl+Shift+R). The "Save" status text appears in the session header; click it for the settings. You can also confirm the plugin is live from a conversation (save_money_status).

Upgrading to a newer version (e.g. 1.2.5 → 1.3.0):

The commands below use pnpm dsh; if you launched DSH via npx, replace pnpm dsh with npx @deepseek-ai/dsh.

# on the build machine:
cd dsh-save-money && git pull && cd plugin && npm pack    # fresh dsh-save-money-<new>.tgz
scp dsh-save-money/plugin/dsh-save-money-1.3.2.tgz pi@<pi-ip>:~/

# on the target:
pnpm dsh plugin --profile web remove dsh-save-money
pnpm dsh plugin --profile web add ~/dsh-save-money-1.3.2.tgz
pnpm dsh --profile web                # restart, then hard-refresh the browser

Your settings survive upgrades (they live in save-money.config.json, untouched by remove/re-add).

Uninstalling:

pnpm dsh plugin --profile web remove dsh-save-money

Path 3: development workflow (what this repository actually uses: link install + HMR hot reload)

Changes take effect immediately — no DSH restart and no tgz needed. This is the form used while developing the plugin: dsh plugin add link: links the plugin/ directory straight into the profile, and a cordis-plugin-hmr hot-reload plugin watches the build output. Save the source → npm run prepare → the running DSH hot-swaps the new plugin; hard-refresh the browser to see the client UI.

One-time setup (on the development machine):

1. Build and link-install:

   cd dsh-save-money
   npm run prepare                          # src/*.ts -> plugin/index.js + plugin/client.js
   pnpm dsh plugin --profile web add link:D:/git/github/dsh-save-money/plugin   # use your repository's absolute path
   

2. Configure hot reload: edit ~/.dsh/profiles/web/cordis.patch.yml (create it if missing) and replace root with your repository's plugin directory absolute path:

   - insert:
       - id: save-money-hmr
         name: '@deepseek-ai/cordis-plugin-hmr'
         config:
           root: ['D:/git/github/dsh-save-money/plugin']
           ignored: ['**/node_modules', '**/.*']
           debounce: 100
   

3. Start DSH (pnpm dsh web / npx @deepseek-ai/dsh web) and open the browser (default http://127.0.0.1:3080).

Daily dev loop:

# after editing src/*.ts, run once:
npm run prepare        # rebuild -> writes plugin/index.js + plugin/client.js

DSH hot-replaces the plugin within ~0.1s (look for [hmr] logs in the terminal) — no restart; hard-refresh the browser (Ctrl+Shift+R) to see client-side changes.

Note: link: and the Path 2 bundle install are mutually exclusive — if you installed the bundle before, run pnpm dsh plugin --profile web remove dsh-save-money first, then add link:.

Config persistence (all forms)

The plugin writes its settings to save-money.config.json (excluded by .gitignore, never committed): loaded automatically at startup, persisted immediately on every change. The config file location is resolved at runtime by walking a candidate list — the first directory that actually contains a config file wins:

1. the directory recorded by the pointer file ~/.dsh/save-money-config-path.json (the last real location, so a restart resolves the same file even when no session matches);
2. the current session's workspace directory;
3. every session workspace whose path ends in dsh-save-money (the newest one wins when several exist);
4. the DSH startup directory itself (process.cwd(), official install form);
5. a dsh-save-money directory sibling to the DSH startup directory (the README quick-install layout: ~/app/deepseek-harness next to ~/app/dsh-save-money);
6. final fallback: sandboxPolicy.workspaceRoot (the DSH install dir).

On a fresh install (no config anywhere) the plugin prefers to write the config into the repo directory (the dsh-save-money dir matched by step 4/5) instead of polluting the DSH install dir, and records a pointer in ~/.dsh/ so every later restart loads the same file. Deleting the config file resets all settings.

Troubleshooting

Symptom	Cause & fix
zsh: command not found: dsh / dsh: command not found	You are running DSH from source — dsh is only available inside the deepseek-harness directory as pnpm dsh ... (or ./node_modules/.bin/dsh). Never use bare dsh outside it.
Plugin fails to load with ReferenceError: harness is not defined	You are running a build older than v1.2.2 — the official form was fixed in v1.2.2. Rebuild (npm run prepare), re-pack, reinstall, and restart.
Installed but no status text / banner / settings page	Fully restart DSH (Ctrl+C, start again) and hard-refresh the browser (Ctrl+Shift+R) — the Client half is discovered at startup. If it still does not appear, you are running a build older than v1.2.4 — upgrade.
UI shows but the Enable checkbox (and other settings) do nothing	You are running a build older than v1.2.5 — the plugin used to start before the Web server was ready, so UI requests could not reach it. Upgrade to ≥ v1.2.5 and restart.
Where is my config file?	Resolved automatically from the 6-step candidate list above (session workspace / repo dir preferred; ~/.dsh/save-money-config-path.json records the last location). Deleting it resets all settings.

Quick start

The steps below apply to every install form — Path 1 / Path 2 / Path 3 all ship the same settings UI. You can also configure through the tools in a conversation (save_money_configure, save_money_status).

1. After install and activation, click the "Save · 🟢 Working" status text in the top-right of the session header (next to the Session log) to open settings (the single persistent entry); or use the system settings page (sidebar → Settings → Save-money);
2. Click One-click DeepSeek peak/off-peak savings → the peak windows are added automatically (08:58–12:02, 13:58–18:02 Beijing time, with the 2-minute boundary margin);
3. Check "Enable" (the one-click does not auto-enable);
4. Save the window settings — the plugin starts watching: tasks pause automatically at the window start and resume when it ends.

Entries

Entry	Where
Status text (single persistent entry)	Session header top-right (next to the Session log) "Save · 🟢 Working", click to open the settings popover
System settings page	Sidebar → Settings → Save-money
Floating banner	Top capsule when a pause is upcoming / active + End this save mode button (one-shot: ends only the current window, future windows unaffected)

Dynamic tools (Host)

Tool	Purpose
save_money_status	Query state / gate state (gate: open|closed) / window / pause record / UTC projection
save_money_configure	Configure (enabled / timezone / warnMinutes / windows)
save_money_end_window	End save mode for the currently active window only (one-shot, in-memory): resume now / cancel the upcoming pause; next windows still take effect
save_money_debug_tick	Dev tool: manually advance the state machine
