Name change

First published as dsh-usage-stats. The package and repository are now dsh-hub-oauth-gateway (effective with 1.1.0). Remove any old entry before reinstalling. Local data files and the internal Cordis plugin id stay the same, so historical usage is preserved.

	Use this	Still works / unchanged
npm (recommended)	dsh plugin --profile web add dsh-hub-oauth-gateway	Old npm name is no longer updated
GitHub / development	dsh-hub-oauth-gateway	—
Cordis plugin id	usage-stats	unchanged
SQLite database	${DSH_HOME}/storages/usage-stats-v1.sqlite	unchanged
CLI	dsh-coding-oauth	dsh-grok-build (alias)

Release history lives in CHANGELOG.md.

Features

• Quick Peek + Full Dashboard — floating HUD (or sidebar button); tabbed overview / trends / accounts / details / local; today / 7d / 30d / month; compare prior period; manual refresh.
• Tabbed Settings — Display / Accounts / Gateway / Capabilities / Providers / Fees under Settings → Usage Center.
• Presets and modules — Minimal, Quota, Cost, Analyst; custom module order; density, motion, provider aliases and colors.
• Activity heatmap — 370-day calendar + streak in the configured timezone.
• Local history — projects DSH usage into SQLite by (session, turn, step); later samples replace, never double-count.
• Cost estimates — user-owned per-million prices with coverage ratio; missing prices are never treated as free.
• Subscription fee ledger — local subscription/top-up costs; payback multiples when currencies match.
• Trends and forecasts — hour/day/week/month buckets; bounded linear extrapolation as a distinct series.
• Account and quota adapters — balances, windows, reset times, stale/last-success, soft alerts (no hard blocks, no outbound notify).
• CSV / JSON export — filtered, daily, or bundle layouts; optional session redaction; spreadsheet-injection defense.
• Coding-subscription OAuth — Grok Build, Codex, Kimi Code, Claude Code via device code / browser / PKCE paste; models appear as (OAuth); one-way CLI credential Pull.
• Optional loopback API gateway — default-off OpenAI/Anthropic-compatible server for your own tools.
• Optional capabilities — Codex search / images / usage / Fast and Grok Imagine default off; apply live.
• Opt-in local monitor — read-only CLI auth snapshots and cross-tool token scans (never conversation content).
• Bilingual UI — Chinese and English through DSH locale services.

Screenshots

Captured against DeepSeek Harness Web with this plugin installed (empty local history is normal for a fresh profile).

Floating HUD — today’s metric plus multi-account quota chips

Quick Peek — compact 2×2 KPIs with a one-click jump to the full dashboard

Full dashboard — ranges, tabs, refresh, and CSV / JSON export

Settings → Usage Center — Display / Accounts / Gateway / Capabilities / Providers / Fees

Problems this plugin solves

You searched / saw	What was actually broken	What this plugin does
Usage / cost / quota scattered across CLIs and providers	No single local history or coverage-aware cost view	SQLite projection + price rules + account adapters in one Usage Center
SuperGrok / ChatGPT Plus / Kimi Code / Claude Pro in DSH without another API bill	Built-in routes are often pay-as-you-go API keys	Local OAuth routes coexist with existing API-key providers
本轮运行失败 API key is invalid / AUTH mid-turn	GUI maps every AUTH to that banner; OAuth access tokens expire	Proactive refresh and AUTH-aware retry on coding OAuth routes
Want OpenAI/Anthropic-compatible tools against subscription sessions	No safe local bridge	Opt-in loopback gateway (not a public relay)
Token Monitor-style CLI status without pasting secrets	Manual file digging or chat paste	Opt-in localMonitor / localUsage on hardened allowlisted paths

Quick start

# 1. install the current npm release into the web profile
dsh plugin --profile web add dsh-hub-oauth-gateway

# 2. restart the resident dsh web service (operator chooses when)
systemctl --user restart dsh-web.service
# or: dsh-web restart

Then open Settings → Usage Center. For Accounts / Gateway / Capabilities, sign in or enable switches as needed. Full install options (npx installer, GitHub tarball, proxy) are in docs/01-install.md.

Requirements

• DeepSeek Harness Web, verified against @deepseek-ai/dsh 0.1.0-rc.6
• Node.js ^22.19.0 || >=24.0.0
• Loopback DSH Web backend; a controlled local HTTPS reverse proxy to an authenticated private network is OK. Do not expose the plugin API alone or publish unauthenticated to the public internet.

Install

dsh plugin --profile web add dsh-hub-oauth-gateway
dsh plugin --profile web update dsh-hub-oauth-gateway
dsh plugin --profile web remove dsh-hub-oauth-gateway

Compatible installer when the plugin manager is missing: npx --yes dsh-hub-oauth-gateway-install. GitHub /path/to/*.tgz and development path installs are documented in docs/01-install.md. After install, restart Web yourself (dsh-web restart or systemctl --user restart dsh-web.service), then refresh http://127.0.0.1:3080.

Usage

1. Open Quick Peek from the floating HUD (or sidebar button under Settings → Display → entry mode). Settings also links Peek / Full Dashboard.
2. In Full Dashboard, switch overview / trends / accounts / details / local; pick range, metric, and provider/model dimensions.
3. Use the refresh button for immediate projection and account refresh. Ordinary GET reads local snapshots only.
4. Configure Display / Accounts / Gateway / Capabilities / Providers / Fees under Settings → Usage Center.
5. Costs are always estimates — watch the coverage percentage; unpriced tokens are not free.

CLI: dsh-coding-oauth login [--pkce] | import | status | logout (dsh-grok-build is an alias).

Settings

Settings → Usage Center uses six top tabs: Display, Accounts, Gateway, Capabilities, Providers, and Fees. Signed-in provider cards collapse until expanded. API Key / Copilot device auth lives under Providers.

Coding OAuth

On the Accounts tab, sign in to Grok Build, Codex, Kimi Code, or Claude Code (device code preferred on remote/headless hosts; browser/PKCE can paste a code or full redirect URL). Authenticated models appear in the selector with (OAuth).

Allowlisted official CLI OAuth files are discovered read-only. Sync is an explicit one-way Pull (discover → preview → confirm), never auto-import and never writes official CLI files.

Local API gateway

Default off. When enabled, an isolated node:http listener (not the DSH web port) serves GET /healthz, GET /v1/models, POST /v1/chat/completions, POST /v1/responses, and POST /v1/messages on loopback, reusing signed-in OAuth sessions. Bind stays YAML-only; non-loopback bind requires a Bearer key. This is not a remote relay. Details: docs/01-install.md.

Optional capabilities

Seven switches default off and apply live: codexSearch, codexImages, codexImageEdits, codexUsage, codexFast, grokImagineImage, grokImagineVideo. Codex Fast / private endpoints and Grok Imagine stay fail-closed until enabled. See docs/01-install.md and docs/03-configuration.md.

Runtime configuration

Merge config under the existing Cordis entry — do not add a second entry:

# ~/.dsh/profiles/web/cordis.patch.yml
- insert:
    - id: usage-stats
      name: dsh-hub-oauth-gateway
      config:
        refresh:
          usageSeconds: 30
          accountMinutes: 5
          accountConcurrency: 3
          timeoutMs: 15000
        retention:
          usageDays: 730
          accountSnapshotDays: 180
          preserveDeletedSessions: true
        pricing:
          baseCurrency: USD
        accounts:
          monitors: {}
        oauthDevice:
          copilotClientId: YOUR_PUBLIC_OAUTH_CLIENT_ID
        codingOAuth:
          enabled: true
        localMonitor:
          enabled: false
        localUsage:
          enabled: false
          intervalMinutes: 30

Full field reference, monitors, proxy, and pricing import: docs/03-configuration.md and docs/01-install.md. Legacy root config.monitors maps to config.accounts.monitors (do not set both).

Credentials

• Stored through the DSH credential seam; the browser only receives configured / source / writable metadata — never values.
• Local CLI import (Claude, Codex, Gemini, Grok, Amp) never logs absolute paths.
• Copilot device flow keeps the device code server-side; the browser holds only a random flow ID. Configure your own public OAuth client ID before enabling.
• Coding OAuth files: $DSH_HOME/.grok-build-auth.json and other *-oauth-auth.json (0600, atomic write). No HTTP status, log, or UI may return a token.

Data and migration

${DSH_HOME:-~/.dsh}/storages/usage-stats-v1.sqlite

Directory 0700, main file 0600, WAL. Default retention: 730 days usage facts, 180 days account snapshots. First-start migration and rollback notes: docs/04-migration-v1.md.

Privacy and security

• Loopback peer + loopback Host; JSON write bodies; same-origin / forwarded-host rules for reverse proxies (x-dsh-hub-oauth-gateway: 1).
• Ordinary GET is local-only; credential-bearing refresh is explicit POST or scheduled.
• Monitors: HTTPS by default, no URL-embedded credentials, manual redirects, size limits, DNS pinning before connect.
• SQLite excludes credentials, prompts, responses, cwd, and raw provider payloads.
• Analytics and estimates are not invoices. Query only accounts and endpoints you own or are authorized to use.
