dsh-plugin-subscriptions

English | 中文

Use your ChatGPT (Codex), Claude, Grok (X Premium), and GitHub Copilot subscriptions as LLM providers in DeepSeek Harness — no API keys. Codex and Grok log in via OAuth in the dsh web UI (Settings → Subscriptions), while Copilot uses the GitHub OAuth device flow; 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 (settings screenshots use demo accounts and catalog data):

Configure visibility, default reasoning effort, and context together in Edit model list, with shared Save and Cancel actions:

Configure image generation, video generation, and X search per provider. Tool switches apply only to sessions created after saving:

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 composer's stats row gains a subscription usage pill showing the remaining rate-limit window for the provider of the session's current model (Codex when a GPT model is selected, Grok for a Grok model, and so on). Click it to expand every logged-in provider and account — the default account is starred, and the current provider is listed first:

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

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.

image_generate also supports editing: the model passes optional referenceImages (1–5 complete DSH attachment references) to edit or use existing images as sources; omitting it keeps text-to-image generation. References can come from uploads, read_image, or previous generated images. Read local files with read_image first; paths are not attachment references. Copy references from the image reference text or structured tool results. Their order matches the prompt's image order. Edits save new files and return reusable references, including for subsequent edits with another provider.

Codex edits use /backend-api/codex/images/edits; Grok edits use /v1/images/edits. Existing provider preference, logged-out fallback, and session tool policy still apply. Empty arrays, duplicate or invalid references, and attachment-limit violations fail explicitly instead of generating a new image. Editing requires the DSH attachment service.

Image generation and editing share same-provider account scheduling: try the default account first, then prefer the successful account in that session. Explicit quota, authentication, or image-entitlement rejection tries the remaining accounts; a 401 gets at most one credential refresh and retry first. Image-only cooldowns honor provider reset times and clear on login/logout. Transport failures, timeouts, 5xx responses, and invalid requests do not automatically resend, avoiding duplicate images. Set pool.enabled: false or pool.autoAccounts: false (legacy autoFamilies is accepted) to use only the default account. Image scheduling does not use chat catalogs, chat quota scoring, families, or tiers.

Refreshing model lists

In Settings → Subscriptions → provider → Edit model list, use Refresh to bypass the five-minute catalog cache and refresh the conversation model picker too. This is separate from refreshing subscription usage. If models.<provider> is explicitly configured with a non-empty list, that list still overrides discovery.

Codex catalog visibility depends on the client_version request parameter. By default the plugin reads the stable version from the official npm @openai/codex package's public metadata (no CLI installation or subscription credentials sent to npm). Successful lookups are cached in memory for six hours; failures retry after five minutes and retain the last successful version, or the verified 0.153.4 fallback on first use. The lookup has a 1.5-second deadline, shares in-flight work across accounts, and ignores prerelease or regressed versions. Manual model-list refresh also rechecks the version. An explicit plugin configuration field, codexClientVersion: '0.153.4', takes precedence and disables automatic lookup; restart DSH after changing it. Model availability remains account-dependent; see verification notes.
