dsh-balance
English | 中文
A Host + Web Client composition plugin for deepseek-harness
(dsh): queries the DeepSeek Open Platform account balance and estimates the
current session's spend. Installable via dsh plugin add.

Features
- Balance: queries the official
GET https://api.deepseek.com/user/balance
using the harness's own DEEPSEEK_API_KEY credential (the key travels only
over a bounded node subprocess's stdin — never in command lines, logs, or UI).
- Session spend estimate: folds the provider-reported token usage from the
session log (uncached input / cache-hit input / output) and prices each step
with the official peak/off-peak table (peak 9:00–12:00 and 14:00–18:00
Beijing time). Estimate only — the official bill is authoritative.
- Top-bar chip (session header):
余额 ¥x | 会话 ≈¥y, click to refresh;
hover (500 ms) shows a detail tooltip below the button, horizontally
centered and viewport-clamped.
- Settings page (设置 → DeepSeek 余额): balance rows, an auto-refresh
on/off switch, refresh-interval selector (15 s … 5 min or custom),
UI-language selector (
auto follows the host UI / 中文 / English),
and an editable price table (off-peak / peak per model).
Changes persist in the settings document across restarts.
- Model tool:
deepseek_balance returns balance + the calling session's
estimated spend.
- Pause-aware refresh: after 2 refresh cycles without a new user or
assistant message the auto-refresh pauses (5-minute detection cadence); it
resumes when a new conversation appears. Auto-refresh can also be switched
off manually (Settings switch or
/dsh-balance auto-refresh off); while
off, no queries are issued.
- Self-contained: no host-repository changes are required to deploy
(communication rides the built-in
commands Remote namespace).
Installation
Standard (bundle install, recommended):
dsh plugin --profile web add @lemcae/dsh-balance
The installer adds the package to the web profile's dependencies and bundle
list; after restarting dsh web, the loader applies the in-package
cordis.patch.yml automatically. Verify:
- Open any session → the
余额 ¥x | 会话 ≈¥y chip appears in the header with
a hover detail tooltip;
- 设置 → DeepSeek 余额 shows the full card (balance, interval, language, price table);
- Ask the model to call the
deepseek_balance tool.
Manual install (same mechanism, bypassing the installer): edit
$DSH_HOME/profiles/web/package.json — add "@lemcae/dsh-balance": "<latest version>" (as on npm) to dependencies and "@lemcae/dsh-balance" to the
dsh.profile.bundles array — then run pnpm install in that directory and
restart.
Peer dependencies are the official @deepseek-ai/* packages (^0.1.0-rc.5
line, covering rc.5 and rc.6; @deepseek-ai/cordis ^4.0.1) plus react,
provided by the host.
Usage
- Chip: shows
余额 ¥x | 会话 ≈¥y; click to refresh; hover for details
(breakdown, model, 更新于, refresh cadence / pause note).
- Settings: 设置 → DeepSeek 余额 — balance rows, 自动刷新间隔
(15 s … 5 min or custom), 自动刷新开关, 界面语言 (auto / 中文 / English), price-table editor (保存 persists), peak-hours hint.
- Command (also usable from the command palette):
/dsh-balance [refresh | interval <毫秒> | prices <JSON> | language <auto|zh-CN|en> | auto-refresh <on|off>].
- Tool:
deepseek_balance (no arguments).
Configuration
Settings namespace dsh-balance:
| Field | Default | Meaning |
|---|
autoRefresh | true | Enable/disable the auto-refresh timer (/dsh-balance auto-refresh on|off) |
refreshIntervalMs | 30000 | Active auto-refresh interval (5 000–600 000 ms) |
language | auto | Plugin UI language:auto (follow host UI), zh-CN, or en |
prices | see source | { models: { deepseek-v4-flash, deepseek-v4-pro, default } }, each model { offPeak, peak } rates in CNY per 1M tokens |
Prices are picked by Beijing hour: peak for 9:00–12:00 and 14:00–18:00,
offPeak otherwise.
Known Limitations and Deferred Work
- Estimate vs. bill: the spend is computed from the local session log and
may differ from the official bill (provider-side caching policy, unlogged
requests, model renames, price changes). Edit the price table in Settings to
keep it current.
- Unknown models are priced with the
default entry (v4-flash rates).
- Subagents have their own session ids and are not included.
- Compaction: a compacted session resets event seqs; the incremental fold
may keep pre-compaction totals (acceptable for an estimate).
- Session-log noise: every auto-refresh runs a slash command, appending
command/run + command/done events; pause-downshifting reduces this.
- Pause recovery latency: while paused, the client probes once per
PAUSED_REFRESH_MS (5 min); a new conversation resumes the active cadence
at the next probe, so recovery can lag by up to that interval.
- Balance is cached 10 s; the tool and chip may share one API call per cycle.
Model Experience
Request context and condition
What the model sees
The tool schema deepseek_balance (zero parameters) plus its description,
which states it queries the official balance endpoint with the harness
credential and returns the session spend estimate.
Token effect
Zero direct tokens; the tool result is data-dependent (payload with balance,
consumption, prices, idle state).
KV Cache effect
Prefix-stable: tool name, description, and schema are constant; the result
varies per call, which does not invalidate prefix reuse.
