dsh-anthropic-membership
DeepSeek Harness plugin: Sign in with Claude Pro/Max. Uses the same Anthropic membership OAuth grant Claude Code uses (isSubscription: true). No Anthropic API key.
It also unblocks two Anthropic-specific lockups that otherwise freeze a long session:
- Many-image 2000px cap — DSH can store request images with a long edge of 2048px. Anthropic rejects many-image requests above 2000px, and retries keep sending the same history. This plugin downscales request images to a 2000px long edge.
/compact over a 1M window — when the live prompt is already over the model cap, DSH's summarizer replays that same prompt and fails with Compaction could not produce a useful summary. This plugin slims compaction calls (drop images and reasoning, truncate huge tool text) so /compact can land.
Install
Requires the dsh CLI.
dsh plugin --profile web add github:antonio-mastropaolo/dsh-anthropic-membership
From a local checkout:
git clone https://github.com/antonio-mastropaolo/dsh-anthropic-membership.git
dsh plugin --profile web add file:./dsh-anthropic-membership
Restart dsh web. Open Settings → Models. On the Anthropic card: Sign in with Claude Pro/Max. Then pick an anthropic / claude-* model.
If the UI is down:
node login.mjs
node logout.mjs
What it writes
- Settings:
llm-pi-ai.providers.anthropic (no apiKeyEnv) in ~/.dsh/settings.yaml, or $DSH_SETTINGS if set. If you launch DSH from Ollama and ~/.ollama/launch/dsh/settings.yaml exists, that file is used instead.
- Grant:
llm-pi-ai/anthropic in ~/.dsh/.credentials.yaml (mode 0600). Never logged.
Control API
Loopback only, 127.0.0.1:8185 (override with DSH_MEMBERSHIP_PORT; the Settings button expects 8185).
| Method | Path | Notes |
|---|
| GET | /healthz | { ok: true } |
| GET | /status | { signedIn, expiresAt, imageCap, compactionSlim } — Origin must be the DSH UI if Origin is sent |
| POST | /login /logout | Requires Origin: http://127.0.0.1:3080 (or localhost) and header x-dsh-membership: 1 |
CORS does not reflect arbitrary Origin. A missing CSRF header is 403. /login is 409 if a login is already in flight.
Tests
npm test
Needs a DSH install on disk so sharp resolves (or set DSH_NODE_MODULES to that node_modules directory).
