dsh-muse-code

Unofficial DeepSeek Harness bundle that serves Meta Muse Code models through a Muse Code subscription and adds a native device-code login flow.

Unofficial and experimental. This plugin uses a Muse Code subscription credential from DeepSeek Harness. Meta's terms limit that credential to Muse Code, so this use may not be supported and Meta may suspend or revoke accounts or credentials. Use it at your own risk; the authors cannot recover an account. Read DISCLAIMER.md before installing.

What it does

• Adds a muse-code model route to DSH through a second @deepseek-ai/dsh-llm-pi-ai instance, with api: openai-responses and baseURL: https://api.meta.ai/v1.
• Registers an authorization flow, Muse Code (subscription), that runs Meta's device login and mints the account-bound inference key.
• Stores that key in the DSH credential store under the MUSE_CODE_SUB_TOKEN reference; the route reads it per request through apiKeyEnv, so the key never appears in a configuration file.
• Models: muse-spark-1.3, muse-spark-1.2, muse-wonder-1.0, muse-wonder-full-1.0. Availability depends on the subscription plan.

Requirements

• DeepSeek Harness 0.2.1-rc.2 or newer.
• A Meta account with an active Muse Code subscription.
• Node.js 20 or newer on the DSH host.

Install

This plugin is distributed from GitHub; no npm package is required.

dsh plugin --profile desktop add github:TheStreamCode/dsh-muse-code

From a local checkout:

dsh plugin --profile desktop add link:C:\path\to\dsh-muse-code

The bundle inserts its route and auth plugin through cordis.patch.yml; no manual profile edit is required. Restart DSH if the profile does not pick up the bundle immediately.

Sign in

1. Open Settings → Authorization (the credential/sign-in surface).
2. Select Muse Code (subscription).
3. Open the printed Meta URL, enter the printed code, and approve the login.
4. The plugin stores the inference key and commits the credential record.

Alternatively, set MUSE_CODE_SUB_TOKEN in the DSH environment to an already-minted key; the stored credential, when present, takes precedence.

Select the model

Choose the muse-code provider in the DSH model picker and one of the exposed model ids, for example muse-code/muse-spark-1.3. Reasoning effort is available through the route's reasoningEfforts mapping.

Remove access

Delete the MUSE_CODE_SUB_TOKEN credential from the DSH credential store, or sign out of the authorization record, then remove the bundle:

dsh plugin --profile desktop remove @thestreamcode/dsh-muse-code

Development

npm install
npm run typecheck
npm test          # builds lib/ and runs the node:test suite

lib/ is committed because DSH bundle installs from Git may not run a build. Regenerate it with npm run build after any source change.

Compliance

Meta Model API Terms of Service §3.2 restrict the subscription credential to Muse Code. This bundle is an unofficial integration; see DISCLAIMER.md and AUTH_CONTRACT.md.
