DeepSeek Harness plugin: MiniMax Global OAuth / Coding Plan via browser login.
Registers the minimax-portal provider route on DSH's LLM runtime via a
custom LlmAdapter. The user authorizes once through a browser-based
device-code PKCE flow; tokens are persisted to
$DSH_HOME/minimax-oauth.json, refreshed transparently when close to
expiry, and serialized into the DSH_MINIMAX_OAUTH_TOKEN_MINIMAX_PORTAL
env var so the adapter can authenticate Anthropic Messages requests with
Authorization: Bearer <oauth_access_token> against
https://api.minimax.io/anthropic/v1/messages.
The built-in pi-ai minimax route (API-key path that reads
MINIMAX_API_KEY and sends x-api-key) is unchanged and remains
available for users who authenticate via API key. The OAuth path lives on
a separate route id so the two authentication channels never collide.
0.1.1-rc.2 or compatible (any release exposing the
llm and webServer cordis services)^22.19.0 or >=24.0.0The plugin is registered as a DSH bundle in your active profile's
pnpm-workspace.yaml and cordis.patch.yml. The fastest install is
through dsh plugin, which writes both files for you:
dsh plugin --profile web add /absolute/path/to/dsh-llm-minimax-oauth
# or, from inside the plugin checkout:
dsh plugin --profile web add .
Confirm the layer:
dsh --profile web --dump-config
A git install may ask you to allow prepare in the profile's
pnpm-workspace.yaml (pnpm ≥10 refuses lifecycle scripts otherwise):
allowBuilds:
dsh-llm-minimax-oauth: true
When the plugin ships via npm (future), the same command resolves the package from your registry instead of the local path.
Open the Web UI at http://127.0.0.1:3080, go to Settings → MiniMax OAuth,
and click Login with MiniMax. A browser tab opens to the MiniMax OAuth
authorization page. Approve, then return to the settings panel — status flips
to "logged in" within ~5 seconds.
For headless / remote sessions, run the CLI fallback:
dsh-minimax-login # interactive
dsh-minimax-login --no-browser # print URL, do not auto-open
dsh-minimax-login --logout # clear stored token
After login, set the default model in ~/.dsh/settings.yaml:
agent-default-model:
provider: minimax-portal
model: MiniMax-M3
Provider minimax-portal (custom adapter in this plugin) at
https://api.minimax.io/anthropic, exposing MiniMax-M3 (1M context,
vision, reasoning), MiniMax-M2.7, and MiniMax-M2.7-highspeed.
MiniMax-M3 is the default and recommended for the Coding Plan.
The Settings → MiniMax OAuth panel after a successful login:

The browser-side MiniMax authorization page that opens after clicking "Login with MiniMax":

The plugin authenticates with Authorization: Bearer <oauth_access_token>,
matching the MiniMax Global OAuth contract documented at
https://platform.minimax.io/docs/solutions/openclaw and implemented in
OpenClaw's extensions/minimax/provider-registration.ts.
OAuth flow shape (device-code + PKCE S256 + state validation) is byte-identical to OpenClaw's reference implementation:
https://account.minimax.io/oauth2/device/codehttps://account.minimax.io/oauth2/token78257093-7e40-4613-99e0-527b14b39113 (OpenClaw public client id)group_id profile model.completionurn:ietf:params:oauth:grant-type:user_coderefresh_tokenTokens are persisted at $DSH_HOME/minimax-oauth.json (default
~/.dsh/minimax-oauth.json) and mirrored into the
DSH_MINIMAX_OAUTH_TOKEN_MINIMAX_PORTAL env var as a JSON envelope
({access, refresh, expires_at, inference_base_url, oauth_base_url}).

Why two phases (not one)? The browser-facing endpoint returns the device code in <1 second. Token polling runs server-side in the background and writes the credential to disk the moment authorization succeeds. This keeps the HTTP connection short and avoids the "Waiting for browser…" freeze that a blocking poll would cause.
Plugin loads but /minimax-oauth/start returns 405. Check that the DSH
webserver route registration ran. See the build artifact — lib/index.mjs
must contain ctx.effect(() => ctx.webServer.register({...})), not a detached
const r = ctx.webServer.register; r(...). Rebuild with pnpm run build if
the bundle looks stale.
Browser does not open automatically. Popup blockers can prevent
window.open. Either allow popups for 127.0.0.1:3080 or use the manual
flow: copy the verification URL + user code from the Settings panel and
finish authorization in your browser.
Login reports "Token Plan usage limit reached". Account quota exhausted; the OAuth handshake succeeded, but the model endpoint returned 429. Wait for quota reset or upgrade the plan on MiniMax's Token Plan page.
MiniMax OAuth refresh failed: invalid_grant. The stored refresh token
was revoked or expired (server-side policy). Run dsh-minimax-login --logout
and re-authorize.
MiniMax OAuth timed out before authorization completed. The user did
not finish authorization within the device-code lifetime (default ~10 min).
Re-run the login flow.
dsh plugin add fails with prepare script denied. pnpm ≥10 refuses to
run install scripts by default. Edit the profile's pnpm-workspace.yaml
and add the allowBuilds snippet from Install.
$DSH_HOME/minimax-oauth.json with 0600 perms.
Do not commit or share this file.refresh_token is sensitive — anyone with access can mint
access tokens until explicitly revoked from your MiniMax account settings.DSH_MINIMAX_OAUTH_TOKEN_MINIMAX_PORTAL is a process-local env var
mirroring the persisted token; it is not exported or sourced from any
shell rc file by this plugin.dsh plugin --profile web remove dsh-llm-minimax-oauth
Then remove the persisted credentials:
rm -f ~/.dsh/minimax-oauth.json
unset DSH_MINIMAX_OAUTH_TOKEN_MINIMAX_PORTAL
The built-in pi-ai minimax route (API-key path) is untouched and remains
usable after uninstall.
This plugin is a working reference for registering routes through
ctx.effect() in a DSH web bundle. Two patterns to copy:
// Direct method call — preserves `this` binding via the Reflect proxy.
// NEVER detach the reference (`const r = ctx.webServer.register; r(...)`),
// because the unbound method call crashes inside the WebServer with
// `Cannot read properties of undefined (reading 'exact')`.
ctx.effect(
() => ctx.webServer.register({ kind: 'exact', path: '/your/path', handler: ... }),
'descriptive-label',
)
// Client-side slot registration — `slots` must be declared in `inject`.
ctx.effect(
() => ctx.slots.inject('your.slot.name', () =>
ctx.slots.register({ name: 'your.slot.name', ... }, YourComponent)),
'label',
)
The plugin also shows the 2-phase OAuth pattern: server returns device-code + user code immediately, browser opens the URL, polling runs in the background. Avoid blocking the HTTP request on long-running device-code flows.
src/index.ts exports the runtime pieces:
import {
// LlmAdapter registered against the `minimax-portal` route
MiniMaxAdapter,
// File-backed token store with atomic writes
FileCredentialStore,
// OAuth error class with stable `.code` values
MiniMaxOAuthError,
// OAuth helpers (2-phase)
startAuthorization, // phase 1: request device code, return userCode + verificationUri
waitForToken, // phase 2: poll for token, persist state
// Access helpers
resolveAccessToken, // returns a valid access_token, refreshing if expired
refreshAccessToken, // force-refresh using stored refresh_token
// Token envelope serialization (for env var mirroring)
readSerializedToken,
// Constants
MINIMAX_PROVIDER_ID, MINIMAX_INFERENCE_ENV_VAR,
MINIMAX_DEFAULT_MODEL_CATALOG, ...,
} from 'dsh-llm-minimax-oauth'
The dsh.client slot registration lives in src/client/apply.ts. The
React UI for the Settings panel is in src/client/index.tsx.
OAuth flow shape mirrors OpenClaw's reference implementation: https://github.com/openclaw/openclaw/blob/main/extensions/minimax/oauth.ts
Endpoint URLs, scope, client id, PKCE method, grant type, and refresh-token handling are identical.
