Provider Extension · 提供商拓展插件
简体中文
dsh-provider-extension is an unofficial community plugin for DeepSeek Harness that owns the composer's provider seat in DSH Desktop and hosts one integration module per provider.
This project is not affiliated with or endorsed by DeepSeek. DeepSeek Harness and related names are trademarks of their respective owners.
This project was previously published as dsh-model-panel. The installer migrates an existing installation automatically.
Provider integrations
| Provider | State | What the plugin adds |
|---|
ChatGPT / Codex subscription (dsh-codex-subscription 2.x) | Implemented | Lists every saved account, switches the real active account, and shows each account's weekly remaining quota |
Antigravity (dsh-antigravity-auth 0.1.4-rc.1) | Implemented | The provider settings page acknowledges the companion's risk notice, signs in a Google account, and lists the models that account reports |
| OpenAI GPT (API) | Planned | — |
| Google Gemini | Planned | — |
| OpenCode | Planned | — |
Each provider gets its own module under src/client/providers/. Nothing is claimed as integrated until it is implemented and accepted in a real DSH window.
Integrations stay in their upstream projects. dsh-antigravity-auth (MIT, © suntianc) owns the Antigravity OAuth flow, its wire identity, and the LLM adapter that publishes Antigravity model routes; this plugin only drives that bundle's loopback-guarded account RPC from its provider settings page and never handles tokens. Install it with dsh plugin --profile desktop add dsh-antigravity-auth@0.1.4-rc.1.
Features
- Uses DSH's authoritative per-session
ModelDirectory; it does not create a second model catalog.
- Replaces the shipped
conversation.input.model visual seat while keeping its authoritative service and /model command.
- Renders exactly two model-related controls: a provider/account picker followed by a model/reasoning picker.
- Shows the chosen provider's models as accent-colored effort sliders, and the active model's declared reasoning-effort buttons.
- Keeps models without reasoning controls selectable.
- Choosing an ordinary provider changes the browsed catalog group; the active session model changes only after a model is chosen.
- Reports unsupported context-window selection honestly instead of showing fake 256K/512K/1M controls.
ChatGPT / Codex subscription accounts
- Every saved account is listed under its provider with its label, masked email, and active marker.
- The header shows the account count instead of a model count.
- Selecting an account calls the subscription plugin's authenticated
account/select RPC, refreshes its quota indicator, and reloads the model directory. OAuth credentials never reach this plugin.
- The active account's weekly remaining quota is read automatically when the list opens.
- Upstream's
usage endpoint only reports the active account, so another account's quota is read on demand: the plugin switches to it, reads, and immediately switches back. A failed restore is reported instead of leaving the switch silent.
Compatibility
Verified in DSH Desktop v2.0.9 against the public 0.1.2-rc.1 DSH package contracts. Those contracts are pre-release APIs, so newer Desktop versions may require a plugin update.
The current selection request is limited to:
{ provider: string, model: string, reasoningEffort?: string }
A real context budget requires Host request preparation, persistence, provider support, and compaction integration. Catalog metadata alone is not treated as a working backend capability.
Install
Requirements: DSH Desktop with an initialized desktop profile, Git, and Node.js 20 or newer.
git clone https://github.com/forestbiankiii/dsh-provider-extension.git
cd dsh-provider-extension
node scripts/profile.mjs install
The repository includes prebuilt lib/index.js and lib/client.js, so installation does not require npm install or a compiler.
The installer:
- removes every earlier package name (
dsh-model-panel, @dshx/client-ui-model-panel) from dependencies, bundles, patch rows, and runtime copies;
- copies an allow-listed runtime package to
~/.dsh/local-plugins/dsh-provider-extension;
- declares a local file dependency in
~/.dsh/profiles/desktop/package.json;
- copies the runtime into the profile's
node_modules for immediate resolution;
- adds
dsh-provider-extension exactly once to dsh.profile.bundles;
- removes legacy/manual
provider-extension and model-panel rows from the user patch so the bundle cannot be registered twice;
- backs up both edited profile files first.
It never edits the installed application or app.asar. If your home or profile differs:
node scripts/profile.mjs install --dsh-home D:\path\to\.dsh --profile desktop
Then fully quit and restart DSH Desktop. Reloading the page is insufficient when changing the composed plugin rows.
Update
From the cloned repository:
git pull --ff-only
node scripts/profile.mjs install
Restart DSH Desktop afterward. Re-running the installer is idempotent and creates a fresh backup.
Upgrading from dsh-model-panel needs no extra step: running the installer performs the migration, including removing the old runtime copies.
Uninstall
From the cloned repository:
node scripts/profile.mjs uninstall
Restart DSH Desktop afterward. The uninstaller removes only this plugin's exact dependency, bundle entry, legacy/manual patch rows, and runtime copies, while preserving a backup of the edited profile files.
Develop
npm ci
npm run check
npm run check performs strict TypeScript checking, component/policy/installer tests, rebuilds the DSH client-module artifact, and verifies the publishable package. The dedicated builder uses esbuild plus Lightning CSS, externalizes DSH-provided runtime modules, and wraps browser output in window.__ModuleLoader__.load(...).
UI and runtime changes must pass the real-window acceptance gate documented in CONTRIBUTING.md: install the candidate locally, let the requester try it in the current DSH Desktop window, and wait for explicit approval before any push, tag, or release.
Architecture
src/index.ts — empty Host carrier required by the Cordis loader.src/client/index.ts — client registration and lifecycle-owned stylesheet.src/client/ProviderPanel.tsx — composer triggers, popovers, sliders, and accessibility behavior.src/client/providers/codex.ts — ChatGPT/Codex subscription roster, account switching, and quota reads.src/client/selection.ts — pure model/effort selection policy.cordis.patch.yml — bundle patch registering the provider-extension row.scripts/profile.mjs — backup-first profile installer/uninstaller and rename migration.lib/client.js — prebuilt browser artifact consumed by DSH.
The plugin declares sessions, remote, and remote.session because modelDirectories.directoryFor(sessionId) reads those services through the caller's Cordis context.
Privacy and security
The plugin reads only the current session's model-directory state and calls its existing load/select methods. It optionally reads the secret-free account roster exposed by dsh-codex-subscription 2.x and calls that plugin's own authenticated endpoints for account switching and quota. It does not read prompts, messages, files, or credentials, makes no independent third-party requests, and includes no telemetry. See SECURITY.md.
