Arthur onboarding sub-skill — Platform Step 2: Authenticate to Arthur Platform using service account credentials (OAuth2 client credentials). Reads/writes .arthur-engine.env.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Arthur Onboard — Platform Step 2: Authenticate to Arthur Platform **Goal:** Establish `ARTHUR_PLATFORM_CLIENT_ID` and `ARTHUR_PLATFORM_TOKEN` in `.arthur-engine.env`. ## Read State ```bash cat .arthur-engine.env 2>/dev/null || echo "(no state file)" ``` Parse `ARTHUR_PLATFORM_URL`, `ARTHUR_PLATFORM_CLIENT_ID`, `ARTHUR_PLATFORM_CLIENT_SECRET`, and `ARTHUR_PLATFORM_TOKEN` from the output. **State write helper** — use this pattern to update individual values without clobbering others: ```bash STATE_FILE=".arthur-engine.env" grep -v '^ARTHUR_PLATFORM_TOKEN=' "$STATE_FILE" 2>/dev/null > /tmp/ae_env_tmp && mv /tmp/ae_env_tmp "$STATE_FILE" || true echo "ARTHUR_PLATFORM_TOKEN=$TOKEN" >> "$STATE_FILE" ``` --- ## If Stored Credentials Exist — Verify or Auto-Refresh If both `ARTHUR_PLATFORM_CLIENT_ID` and `ARTHUR_PLATFORM_CLIENT_SECRET` are present in state, invoke the `arthur-onboard-platform-token` sub-skill to get a fresh token, then verify it: ```bash ARTHUR_PLATFORM_URL=$(grep '^ARTHUR_PLATFORM_URL=' .arthur-engine.env 2>/dev/null | cut -d= -f2-) ARTHUR_PLATFORM_TOKEN=$(grep '^ARTHUR_PLATFORM_TOKEN=' .arthur-engine.env 2>/dev/null | cut -d= -f2-) …

How to install
mdr add arthur-ai/arthur-engine/arthur-onboard-platform-access@sha256:4c1a8eaa9d3197d5The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
