dsh-ark-quota

English · 简体中文

A DeepSeek Harness (DSH) web plugin that shows your 火山方舟 (Volcano Ark) Coding Plan subscription quota as a fixed widget in the sidebar footer — without ever leaving the DSH GUI.

Current version: v0.1.0 (see VERSION)

• Host half (lib/index.js) signs the control-plane OpenAPI GetCodingPlanUsage (falling back to GetAFPUsage for Agent Plan) with your Volcengine AK/SK (SigV4 variant) behind a same-origin route (/ark-quota), because the OpenAPI gateway does not allow CORS from the DSH origin. No browser, no cookies, no CSRF.
• Browser half (lib/client.js) renders the quota card / rail pill and auto-refreshes when the settings change; a dedicated Settings → 方舟额度 section lets you paste the AK/SK straight into the DSH settings UI.
• tools/check.mjs is a zero-dependency CLI that signs one request with your AK/SK and prints your subscription quota — use it to verify keys before/after configuring.

⚠️ Security note: the quota API is authenticated with your 火山方舟 access keys (AccessKey ID + Secret). These are real credentials for your Volcengine account. Keep them private, never commit them, and never paste them anywhere except your own cordis.patch.yml / settings.yaml (or the DSH settings UI, which marks them role('secret') and never returns their values to the browser).

Features

• Sidebar footer widget: wide card (session / weekly / monthly usage bars) on the footer action row, or a compact remaining-percent pill.
• Agent Plan fallback: when the account is not subscribed to Coding Plan, the proxy auto-detects GetAFPUsage and renders the absolute quota windows instead.
• Live maintenance: keys are read from the ark-quota settings namespace ($DSH_HOME/settings.yaml, hot-reloaded by dsh-settings-file). A change drops the cache immediately — no server restart.
• Settings UI: a top-level 方舟额度 section in the DSH settings (sibling of the 侧边卡片 / 配置同步 sections) saves AK/SK with one click (write-only fields, hot-applied).

Requirements

• DeepSeek Harness web runtime (dsh web), with dsh-settings-file composed (it is in the default web profile).
• A 火山方舟 Coding Plan subscription and a logged-in console.volcengine.com session.

Installation

1. Make the package resolvable from your profile. The loader resolves name: dsh-ark-quota
   from the profile directory, so the package must physically live at
   $DSH_HOME/profiles/<profile>/node_modules/dsh-ark-quota (Node's normal node_modules walk).
   Get it there either by cloning straight into the module path:

   git clone https://github.com/lordqyxz/dsh-ark-quota \
     "$DSH_HOME/profiles/<profile>/node_modules/dsh-ark-quota"
   

   or by installing it as a dependency of the profile, e.g.
   dsh plugin --profile <profile> add github:lordqyxz/dsh-ark-quota (forwards to pnpm add).

2. Add the package to your profile's workspace (pnpm-workspace.yaml under $DSH_HOME/profiles/<profile>/)
   so pnpm treats the installed copy as a workspace member and links its dependencies:

   packages:
     - .
     - 'node_modules/dsh-ark-quota'
   

   Then run pnpm install in the profile directory. If your harness already provides the
   profile's dependencies (e.g. the $DSH_HOME/profiles/node_modules module fallback of an
   npx-installed harness), pnpm install is optional — the package's deps
   (@deepseek-ai/schemastery) already resolve, so placing the package is enough.

3. Add an entry to your profile's cordis.patch.yml:

   - insert:
       - id: ark-quota
         name: dsh-ark-quota
         config:
           accessKeyId: ''        # optional here — fill it in the DSH Settings UI instead
           secretAccessKey: ''
           region: cn-beijing
           version: '2024-01-01'
           refreshMs: 300000
   

4. Apply and verify. Editing cordis.patch.yml is hot-applied by DSH's HMR watcher on recent
   versions (the host route and client boot graph recompose without a restart) — check it with
   curl -i http://127.0.0.1:3080/ark-quota. If the route isn't live, restart the DSH server
   and refresh the browser. The widget appears at the bottom of the sidebar.

Getting the access keys

1. Open the Volcengine console → 访问控制 (Access Control) → API 访问密钥 (API Access Keys).
2. Create an AccessKey (or reuse one) and note the AccessKey ID and Secret Access Key.
3. Fill them into the plugin — easiest from the DSH Settings UI: Settings → 方舟额度
   (saved to $DSH_HOME/settings.yaml, hot-applied, no restart needed). Or set
   accessKeyId / secretAccessKey in cordis.patch.yml.

💡 Verify: run node tools/check.mjs <accessKeyId> <secretAccessKey> (or
ARK_AK=… ARK_SK=… node tools/check.mjs) to confirm the keys sign correctly against the Ark
control-plane OpenAPI and print your subscription quota — no browser involved.

Usage

• The widget polls /ark-quota every refreshMs (default 5 min) and every time the settings namespace changes.
• Click the ⟳ button (or ?force=1) for an immediate refetch.
• When the keys are missing or wrong you'll see an error card; fix them in Settings → 方舟额度 (or re-run node tools/check.mjs) and the widget updates itself.

Configuration

All settings live in the ark-quota settings namespace. The composition entry config in cordis.patch.yml is the base; the user layer in $DSH_HOME/settings.yaml overrides it and is hot-applied.

API

GET /ark-quota → same-origin JSON:

{
  "ok": true,
  "status": "Normal",
  "updatedAt": 1786639101,
  "hasReward": false,
  "quota": [
    { "level": "monthly", "percentUsed": 90.18, "percentRemaining": 9.82, "cap": 100, "rewardTotalPercent": 0, "resetAt": 1786639101 }
  ]
}

On failure: { "ok": false, "code": "unauthorized" | "upstream" | "network", "message": "…" } (HTTP 401 / 502 / 504 respectively).

Security notes

• The /ark-quota, /ark-quota/status, and /ark-quota/credentials routes are localhost-only (bound to the DSH server) and are unauthenticated: any process on the same machine can read your quota figures, force an authenticated refresh, or overwrite your access keys via POST /ark-quota/credentials (the same exposure as directly editing settings.yaml on that machine). They never echo your access keys (responses carry only booleans / quota numbers), and /ark-quota/credentials accepts only a fixed-shape accessKeyId / secretAccessKey pair of strings — no user-controlled URL, so they cannot be used as a proxy/SSRF vector or leak the Volcengine credentials. Don't expose the DSH server beyond loopback while this plugin is loaded.
• Access keys are real credentials. They are stored in cordis.patch.yml / settings.yaml under $DSH_HOME, declared with role('secret') in the settings schema (the DSH settings UI shows them as write-only fields and never sends their values back to the browser), and are excluded from git (see .gitignore).
• tools/check.mjs only signs one request with the keys you pass on the command line / via ARK_AK/ARK_SK; it never writes them to disk and never prints them in full.
