dsh-plugin-subscriptions

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, and Grok 4.6 / 4.5 (levels and defaults come from each provider's live catalog, not a hardcoded list):

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)

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).

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

• dsh web, open the printed URL.

• 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.

• 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.

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] }

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.

Layout

• src/index.ts — plugin entry: config schema, adapter registration, auth-change re-announce, RPC wiring

• src/auth/ — PKCE/JWT helpers, token store, OAuth flow engine (temp loopback callback server), Claude Code credential reader (Keychain/file), /subscriptions-auth RPC channel

• src/providers/ — per-provider OAuth constants/exchange/refresh + LlmAdapters

• src/translate/ — dsh Message[] ⟷ OpenAI Responses / Anthropic Messages wire formats, SSE → StreamChunk

• src/tools/ — x_search, image_generate, and video_generate

• src/client/ — the Settings → Subscriptions page (browser half, zh/en, theme-token aware)
