At a Glance

Real-time cost tracking for DeepSeek Harness: monitors current session and historical model call costs, official account balance, budget progress, and peak/off-peak pricing tiers. Optional integration with OpenCode Go subscription and multi-vendor Coding Plan quotas, with one-click sync from the official pricing page.

Core Features

• Real-time session cost accumulation: Plugin captures input, cache read/write, output, and reasoning tokens for each model call, charging per the price list; badge position can be toggled between below the input area and the session title bar
• Global ledger & history: Daily aggregated costs, call counts, and session details, retaining the last N days (default 180); today/month/cumulative cards and Codex-style 26-week daily usage heatmap
• Budget box & overspend alerts: Rounded box at sidebar bottom shows budget, used percentage, today's cost, and cost-to-budget ratio; ≥80% turns yellow, ≥100% turns red, alerts only without blocking calls
• Official account balance: Calls official open platform balance API, reuses the same API Key from model requests; total balance / gifted / top-up breakdown shown in sidebar top or settings page, in-process cache expires per refresh interval
• Multi-tier quota queries: OpenCode Go rolling 5h / this week / this month usage percentages, overlaid with six vendor Coding Plan quotas (Anthropic Claude, Z.ai / 智谱, MiniMax, Kimi / Moonshot, OpenRouter, SiliconFlow)
• One-click official price sync: Scrapes official pricing page to parse base and peak/off-peak rates, auto-writes to price table while preserving historical prices; provides AI prompt document for third-party vendor price manual verification

Technical Implementation

• Language: JavaScript (ESM, TypeScript not enabled; 5 .js source files under lib/ + single-file browser bundle)
• Key dependencies: zod (config/state schema validation), @deepseek-ai/dsh-credentials (OpenCode Go / Coding Plan / balance Key parsing), @deepseek-ai/dsh-home-paths (ledger root directory resolution)
• Architecture pattern: dual-half host plugin. Host half intercepts model stream via ctx.on('llm/stream', ...) to capture usage blocks and write to ledger per price list; ctx.inject(['sessionProjections']) registers costUsage session projection (client prices by current price table); ctx.provide('costMeter', service) exposes ledger snapshot/config/refresh/sync/reset RPC, hand-written typertRemote binding to match Typert gateway validation. Client half is single-file bundle, injects into four slots: conversation.composer.dock, conversation.session.header.actions, sidebar.footer.action, settings.section; styles entirely based on --dsw-* theme variables following light/dark mode
• Entry files: host entry lib/index.js (apply / name = 'cost-meter'); client entry lib/client.js; mount declaration cordis.patch.yml (1 line Loader insertion in web profile) + package.json#dsh.bundle.patch

Use Cases

When DSH users want a visible "ledger feel" for model spending — real-time view of current session and historical cost trends, setting monthly budgets with progress bar alerts, verifying official price tables in settings, checking OpenCode Go and multiple Coding Plan remaining quotas at a glance. This plugin consolidates all measurable dimensions into a single "Cost" settings section, eliminating the need to switch between multiple official consoles.

Prerequisites & Compatibility

Installation

dsh plugin --profile web add github:Han-1413141/dsh-cost-meter

Configuration Options

Visualized editing by default in Settings → Cost all sections; below is the adjustable field overview (excerpt from lib/store.js:27-95, all fields validated by zod schema in updateConfig RPC and auto-saved instantly with 600ms debounce).

FAQ

Q: Is the interface in Chinese or English? Can I switch?

A: Simplified Chinese / English / follow browser (auto) three modes. Default follows browser (zh* → Chinese, others → English), detection result not persisted. Switch in Settings → Cost → Display Settings → Interface Language, entire UI takes effect instantly and auto-saves; balance returned by server and price sync prompts also display in current language.

Q: I don't see balance in the sidebar after installation / display is abnormal. What should I do?

A: Balance depends on DeepSeek API Key in DSH model settings; please configure Key in Settings → Models on first launch or export DEEPSEEK_API_KEY. Balance endpoint strictly only sends to official domain api.deepseek.com, balance query is rejected when baseURL points to non-official domain (model calls unaffected). Balance auto-refreshes every 5 minutes by default, can be disabled in Settings → Cost → Balance display position.

Q: OpenCode Go or Coding Plan quotas disappear automatically / show "not enabled"?

A: Go quota requires DSH credential store or env var OPENCODE_GO_API_KEY, unconfigured shows neutral hint in settings page, won't turn red. Open Settings → Cost → OpenCode Go panel to enable; unsubscribed can disable "Enable" switch. Similar for each Coding Plan: fill Key in corresponding panel or configure env var, disable "Enable" to stop.

Q: How to sync the latest official prices? Will sync overwrite my custom prices?

A: Click "Sync from Official Docs" in Settings → Cost → Data & Sync area, plugin scrapes official pricing page and writes after parsing. Only overwrites same-named model entries listed on official page, custom model entries unaffected; sync reports error and preserves original price table on parse failure, manual edit as fallback.

Q: Will reaching 100% budget stop model calls?

A: No. Budget and overspend alerts only notify without blocking calls; ≥80% turns yellow, ≥100% turns red and shows overspend badge in sidebar bottom budget box. Hard limit requires handling at model layer yourself.

Q: Where is data stored? How to clear all history?

A: Ledger file at $DSH_HOME/storages/cost-meter/ledger.json, retained per historyDays (default 180 days), max 200 session details per day; writes use temp file + atomic rename + 2s debounce. Clear: click "Clear All History" in Settings → Cost → Data & Sync; also can manually delete ledger.json.

Q: How to uninstall?

A: dsh plugin --profile web remove dsh-cost-meter, restart dsh web. Plugin doesn't introduce extra background processes or modify host files; ledger file remains at $DSH_HOME/storages/cost-meter/ledger.json, delete manually if needed.

Q: Page doesn't change after installation/update?

A: Must restart dsh web after plugin installation or update; plugin line, Typert manifest, and client bundle all scanned at startup; only refreshing browser won't reload server-side plugin.

Getting Started Difficulty

Beginner — one dsh plugin add + restart dsh web shows cost panel in sidebar and settings; official price sync requires access to api-docs.deepseek.com. Advanced: read Price Table / Extend Price Table / Multi-provider Model Adaptation (see docs/model-and-plan-adaptation.md) and manually verify non-DeepSeek model prices per vendor.

Known Issues & Limitations

• Official pricing page parsing depends on current page structure: after official redesign, "Sync from Official Docs" reports error and preserves original price table, manual edit as fallback
• Session badge estimates by current price tier: accurate cost based on ledger; historical call costs in ledger precisely recorded per price tier at call time
• Price sync only overwrites same-named model prices listed on official page: custom model entries unaffected
• Balance query enforces official domain whitelist: only api.deepseek.com accepted, balance query rejected when baseURL points to non-official domain, model requests unaffected
• OpenCode Go quota endpoint is opencode.ai/zen/go/v1/usage (community docs): when interface structure changes, settings shows error, can disable display in Display Settings
• Must restart dsh web after plugin install/update: plugin line, Typert manifest, and client bundle all scanned at startup
• Third-party Coding Plan partial balance only: Anthropic OAuth, Z.ai / 智谱, MiniMax Token Plan have verified usage endpoints; Kimi Code subscription weekly window / 5-hour window have no public API-Key-ized endpoint, currently displayed as PAYG balance window; 百炼 Coding Plan / OpenAI Codex / Gemini Code Assist / GitHub Copilot personal have no API-Key-ized usage endpoints, not integrated

dsh web

更新 / 卸载

# 更新:发布新版后用新版 install.ps1 重跑(脚本内固定版本随之更新)
dsh plugin --profile web remove dsh-cost-meter  # 卸载

开发者本地调试

git clone https://github.com/Han-1413141/dsh-cost-meter.git
cd <克隆目录的父目录>
dsh plugin --profile web add link:./dsh-cost-meter  # 符号链接,改 lib/client.js 后刷新页面即生效

计费规则

• 价格单位与官方文档一致:美元 / 1M tokens;
• 成本 = 未命中输入 × cache-miss + 输出 × output + (缓存读 + 缓存写) × cache-hit(缓存写沿用官方历史规则按命中价计费);
• 纯峰谷两档计价(2026-08 起官方方案):峰时段(01:00–04:00、06:00–10:00 UTC)按峰时价,其余按谷时价(谷时价 = 峰时价的一半);基础档与谷时档同价,未启用峰谷时按谷时价计;设置页实时显示当前档位(峰时段/谷时段);预算与今日费用区域显示峰时/平价时段条(当前/下一时段与倒计时),收起态显示竖向峰谷进度条;
• 历史计费正确性:2026-08-16 16:00 UTC(峰谷时代分界)之前的调用按当时的基础价计费,之后的调用按峰谷两档;
• 账本金额恒以美元存储,币种/汇率仅影响显示(默认 1 USD = 7.2 CNY,可改);
• 会话徽章与当日/月度/累计、预算一样,按每次调用的实际时刻精确计费(宿主导出的逐次成本);
• 计费来源为每次模型调用的 usage 块(含子代理、压缩、标题等辅助调用),与账单口径一致;
• 预算与超支提示仅提醒,不阻止调用。

数据存储

• 账本:$DSH_HOME/storages/cost-meter/ledger.json(原子写入 + 2 秒防抖;按 historyDays 保留,每日最多 200 个会话明细);
• 所有设置修改即时自动保存(600ms 防抖),无需手动保存;
• 删除账本文件即可清零,或使用设置页「清除全部历史」。

数据通道:

• 本会话费用:宿主注册 costUsage 会话投影(纯 token 桶 + 按模型拆分),浏览器经 useProjection('costUsage') 读取并按当前价格表计价;
• 全局账本 / 预算 / 余额 / 配置:costMeter/getState | updateConfig | fetchPrices | refreshBalance | resetHistory,经 Typert 网关 RPC(remote.costMeter.*);
• 余额:调用官方 GET {baseURL}/user/balance,复用模型请求的同一把 API Key(凭证服务/环境变量),进程内缓存按 refreshMinutes 过期。

插件不导入 cordis/dsh 的 Service/Context 运行时类(仅 Node 内建模块、zod、dsh-home-paths、dsh-credentials 的纯函数),与宿主共享同一运行时实例,无重复依赖风险。

官方价格同步原理

fetchPrices 抓取官方定价页(Docusaurus 服务端预渲染),解析:

1. 基础价格表(转置布局:首行 MODEL + 模型 id,价格行标签后紧跟价格);
2. 峰谷价格表(每模型两行:OFF-PEAK / PEAK);
3. 生效时间(take effect at …)与峰时段窗口(Peak hours are …)。

解析结果写入价格表并持久化;页面结构变化时同步报错并保留原价格,可手动编辑兜底。

AI 价格同步

docs/AI-PRICE-SYNC-PROMPT.md(中文)与 docs/AI-PRICE-SYNC-PROMPT.en.md(English) 提供可直接复制给任意 AI 的提示词: AI 自主读取官方定价 → 输出多模型、分时(基础/谷时/峰时 + 生效时间)价格 JSON → 人工核对后应用(设置页 / RPC / 文件三选一)。适合官方价格变动时自主同步。

已知限制

• 官方页面解析依赖当前页面结构;改版后「从官方文档同步价格」会报错,可手动编辑价格表兜底;
• 会话徽章按当前价格档位估算,精确费用以账本为准;
• 价格同步会覆盖官方页面列出的同名模型价格,自定义模型条目不受影响;
• 余额查询需要可访问 api.deepseek.com 的网络与有效 API Key;API Key 只会发往官方域名(baseURL 指向非官方域名时余额查询拒绝请求,模型请求不受影响);
• OpenCode Go 额度接口为 opencode.ai 官方端点(社区文档);接口结构变化时设置页会显示错误,可在显示设置中关闭该显示;
• 安装/更新插件后需重启 dsh web 生效。
