dsh-plugin-subscriptions [](https://awesome-dsh-plugin.com)

English | 中文

Use your ChatGPT (Codex), Claude, and Grok (X Premium) subscriptions as LLM providers in DeepSeek Harness — no API keys. Codex and Grok log in via OAuth in the dsh web UI (Settings → Subscriptions); Claude imports credentials from an existing Claude Code session when there is one (macOS Keychain or ~/.claude/.credentials.json) and otherwise falls back to the same browser OAuth flow, so the Claude Code CLI is not required. Tokens live at ~/.dsh/plugins/subscriptions/auth.json (mode 0600) and refresh automatically.

Demo

Settings → Subscriptions: per-provider login/logout, no API keys. Claude imports credentials from Claude Code when available and otherwise uses OAuth, as Codex and Grok always do (account address masked in the screenshot):

Logged-in providers join the session model picker with their live model catalogs:

Models that advertise reasoning levels get an Effort selector in the same menu — Codex models, Grok 4.6 / 4.5, and Copilot's reasoning models (levels and defaults come from each provider's live catalog, not a hardcoded list; Copilot's capabilities.supports.reasoning_effort array is sent as reasoning_effort on chat completions and reasoning.effort on the Responses wire). Models listing both Copilot endpoints (gpt-5.4, gpt-5-mini) normally speak chat completions but reroute to /responses when a request combines function tools with an effort — Copilot rejects that combination on the chat wire:

Codex models whose catalog advertises the fast tier (the codex CLI's fast mode) get a Speed toggle in the composer's tool row, next to the model selector — Standard or Fast (service_tier: priority), per session. The /fast slash command offers the same choice as a popup; it errors with an explanation when the current model has no fast tier.

The image_generate tool renders its result inline in the conversation:

Its provider parameter picks the image backend — the same prompt through GPT (gpt-image-2, top) and Grok (grok-imagine-image-2.0, bottom):

The video_generate tool plays the generated clip inline:

Providers

Route	Subscription	Models
codex	ChatGPT Plus/Pro	live catalog from chatgpt.com/backend-api/codex/models
claude	Claude Pro/Max	all models available in your subscription (Opus, Sonnet, Haiku, Fable — static catalog, updated with the plugin)
grok	X Premium (xAI)	live catalog from api.x.ai/v1/models (chat models only); reasoning efforts from the Grok CLI catalog (cli-chat-proxy.grok.com/v1/models)
copilot	GitHub Copilot	live catalog from api.githubcopilot.com/models (chat models on both wires, with per-model vision flags and reasoning efforts); login uses the OAuth device flow (enter the shown code at github.com/login/device)

Only logged-in providers appear in the session model picker; the lists above refresh on login/logout. Vision-capable models declare ['text', 'image'] input modalities, and image content is translated to each provider's wire format.

Logged-in cards also show subscription usage — per rate-limit window (5-hour session, weekly, and per-model weekly where the plan has one) with the used percentage, a progress bar, and the reset time, plus a Refresh button. Codex usage comes from chatgpt.com/backend-api/wham/usage (also reports the plan), Claude usage from api.anthropic.com/api/oauth/usage, and Grok usage from the Grok Build CLI proxy's cli-chat-proxy.grok.com/v1/billing (the source of the CLI's /usage panel; reports the shared weekly pool and the subscription tier). Copilot exposes no usage endpoint, so its card shows no usage section.

Also included, registered when the matching provider is enabled:

• x_search tool (Grok) — xAI's hosted X search, returning { answer, citations }.
• image_generate tool (ChatGPT or Grok) — gpt-image-2 via the Codex backend, or grok-imagine-image-2.0 via api.x.ai/v1/images/generations. The provider argument picks the preferred provider (gpt, the default, or grok); when the preferred one is logged out the other serves as fallback. Images are saved under ~/.dsh/plugins/subscriptions/images/ and the paths returned. The size/quality arguments map onto Grok's aspect_ratio/quality on the Grok path.
• video_generate tool (Grok) — grok-imagine-video-1.5 via api.x.ai/v1/videos (async submit + poll); MP4s are saved under ~/.dsh/plugins/subscriptions/videos/, the path returned, and the clip plays inline in the conversation. Supports duration (1–15 s), aspect ratio, resolution, and image-to-video via image_url.

Install

With the dsh CLI available, install from npm (prebuilt artifacts, no build permission needed):

dsh plugin --profile web add dsh-plugin-subscriptions

Or install the sources from GitHub:

dsh plugin --profile web add github:V1ki/dsh-plugin-subscriptions

pnpm will ask you to allow this package's build script on first install (git installs fetch sources, not built artifacts); add the printed key to the profile's pnpm-workspace.yaml:

allowBuilds:
  dsh-plugin-subscriptions: true

and re-run the add. Only grant this to packages you trust — it runs the package's code at install time.

From a local checkout instead:

git clone https://github.com/V1ki/dsh-plugin-subscriptions.git
cd dsh-plugin-subscriptions && pnpm install && pnpm build
dsh plugin --profile web add ./dsh-plugin-subscriptions

Headless-only usage without installing into a profile (log in via the web UI first — the token file is shared):

cp overlay.example.yml overlay.yml   # then edit the name: to this checkout's absolute lib/index.js path
dsh --profile headless --patch <checkout>/overlay.yml "your task"

Update

Installed from npm:

dsh plugin --profile web update --latest dsh-plugin-subscriptions

Installed from GitHub: re-run the same add github:V1ki/dsh-plugin-subscriptions command — it re-fetches the sources and rebuilds. A linked local checkout just needs git pull && pnpm build in the checkout.

Either way, restart dsh web afterwards so the new version loads.

Use

1. dsh web, open the printed URL.
2. Settings → Subscriptions: click Connect on a provider. For Claude, credentials are imported instantly if you have run claude and logged in at least once; without them, Claude authorizes in the browser like the others. For Codex and Grok, authorize in the opened browser tab; if the browser flow can't complete (headless host), expand the manual fallback and paste the callback URL or code.
3. In any session, open the model picker (/model) and choose a model under ChatGPT (Codex) / Claude (Subscription) / Grok (Subscription).

Not logged in? The provider stays out of the picker, and requests fail with MISSING_CREDENTIAL pointing at the Settings page; nothing else breaks.

Multiple accounts

Every provider accepts several accounts: once one is connected, the card grows an Add account button (Claude offers Browser authorization and Import Claude Code separately). Accounts are keyed by their identity (email / login) — re-logging the same account updates it in place, a different account appends. Browser authorization signs in whichever account the browser currently uses, so switch accounts there first (or use an incognito window with the manual code) to add a different one. The ★ default account serves the direct provider routes; pool routes use every account. A Claude account imported from Claude Code stays synced with the CLI's credential store; OAuth-added Claude accounts refresh standalone so several accounts never fight over the Keychain entry.

Default reasoning effort per model

Every logged-in provider card in Settings → Subscriptions carries a collapsible Default reasoning effort section. It starts collapsed — the header shows how many models advertise reasoning levels and how many you have overridden — and the model list (with its live catalog lookup) loads only once you expand it, so a provider with dozens of models does not stretch the page or make it pay for a lookup nobody asked for. Expanded, each model that advertises reasoning levels gets a row whose options are the levels that provider's live catalog advertises for that exact model; past 8 such models the section also offers a name filter, and models without reasoning levels collapse into a single count line instead of one dead row each. With several accounts connected, the model list is the union across that provider's accounts, so a model any account advertises gets a row; the levels offered for it come from the first account whose catalog lists it (the ★ default account first), matching what the session picker resolves.

Pick a level to make the session model picker preselect it whenever you switch to the model — no more settling for the provider's own default (e.g. Claude shows Default, Codex models follow default_reasoning_level). Choose Follow provider to clear the override. The choice is stored in ~/.dsh/plugins/subscriptions/model-defaults.json (mode 0600) and survives restarts.

Config

- id: llm-subscriptions
  name: dsh-plugin-subscriptions
  config:
    providers: [codex, claude]        # subset; default all three
    streamIdleTimeoutMs: 300000
    models:                            # override the discovered/built-in catalogs
      codex:
        - { id: gpt-5.6-sol, name: GPT-5.6 Sol, contextWindow: 272000, inputModalities: [text, image] }
      copilot:                         # manual entries disable Copilot catalog discovery
        - { id: gpt-5.6-sol, wire: responses }   # copilot only: force the upstream protocol

wire (copilot entries only) pins a model to chat-completions or responses. Manual entries keep working without it — the field exists because a configured model the live catalog does not know would otherwise default to /chat/completions, which responses-only families (gpt-5.5/5.6, …) reject. Pinning chat-completions also opts out of the tools+effort auto-reroute described above.

Model pools

When a provider has two or more logged-in accounts, the picker shows the union of every account's catalog (duplicates dropped). Pick claude-sonnet-5 under Claude (or gpt-5.4 under ChatGPT) as usual — there is no extra pool group and no new model id.

• Shared models. A model listed by ≥2 accounts failovers between them (sticky, quota-aware). Each account is discovered separately, so a Plus login is not asked to serve a Pro-only model.
• Account-only models. A model listed by only one account is sent to that account. It still appears in the picker even if that account is not the default.
• Explicit account lists (families). Replace the auto member list for one catalog model (same provider only; cross-provider members are ignored). Pin account or omit it for the default.
• Tier extras (tiers, optional). Extra picker rows with heterogeneous fallbacks, listed under the first member's provider. Not created automatically.

Selection is sticky per session (prompt caches survive) with two strategies: priority (first healthy member wins) and quota_aware (the default — each member is scored by its required burn rate, remaining quota / time until window reset, so a window about to reset with plenty left gets spent instead of wasted; the sticky member holds until a challenger out-scores it by switchMargin). Members past 95% on any usage window are gated out; failures fail over before the first stream chunk with cooldowns (retry-after when the provider sends one) — quota and auth failures cool the whole account down (its quota is account-level; Claude's model-scoped lanes cool per member), transient server failures cool only the failing member. Copilot exposes no usage telemetry, so it scores zero and naturally serves as the fallback of last resort.

- id: llm-subscriptions
  name: dsh-plugin-subscriptions
  config:
    pool:
      enabled: true                   # default; needs ≥2 accounts of one provider
      strategy: quota_aware           # or priority
      switchMargin: 2                 # hysteresis factor for quota_aware
      autoAccounts: true              # pool each catalog model across that provider's accounts
      families:                       # explicit account list for one catalog model (same provider)
        claude-sonnet-5:
          - { provider: claude, model: claude-sonnet-5 }                   # default account
          - { provider: claude, account: bob@example.com, model: claude-sonnet-5 }
      tiers:                          # optional extra picker rows
        smart:
          - { provider: claude, model: claude-sonnet-5 }
          - { provider: codex, model: gpt-5.6-sol }
          - { provider: grok, model: grok-4.6 }

Proxy

Every subscription request — token exchanges, model-API streams, usage lookups, model discovery, and the x_search / image_generate / video_generate tools — can be routed through an HTTP(S) proxy. Configure it in Settings → Subscriptions → Proxy → Configure…: enable the flag, enter the proxy URL (http://127.0.0.1:7890), optional username/password, and an optional comma-separated bypass list of hostnames that stay direct (127.0.0.1, localhost, *.example.com). The password is stored in ~/.dsh/plugins/subscriptions/proxy.json (mode 0600) and is never returned to the browser. A "Test" button probes one endpoint through the current configuration and shows the HTTP status/latency.

Changes apply immediately to subsequent requests — no restart needed. The OAuth authorization page opens in your browser and follows the browser/system proxy, not this setting. SOCKS proxies are not supported.

Develop

pnpm install   # devDependencies link into a local deepseek-harness checkout — edit the paths first
pnpm build     # tsc (lib/) + tsdown (lib/client.js browser bundle)
pnpm test      # node --test over compiled unit specs

prepare (used by git installs) runs tsdown.prepare.config.ts: a self-contained bundle build of both faces with all @deepseek-ai/* specifiers external — they resolve from the dsh installation at runtime, so this package never carries a second cordis copy.

After pnpm build, restart dsh web to pick up changes.
