Arthur onboarding sub-skill — Step 2: Ensure Arthur GenAI Engine is available (local install or remote). 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 — Step 2: Ensure Arthur GenAI Engine Is Available
**Goal:** Establish `ARTHUR_ENGINE_URL` and `ARTHUR_API_KEY` in `.arthur-engine.env`.
## Read State
```bash
cat .arthur-engine.env 2>/dev/null || echo "(no state file)"
```
Parse `ARTHUR_ENGINE_URL` and `ARTHUR_API_KEY` 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_ENGINE_URL=' "$STATE_FILE" 2>/dev/null > /tmp/ae_env_tmp && mv /tmp/ae_env_tmp "$STATE_FILE" || true
echo 'ARTHUR_ENGINE_URL=http://localhost:3030' >> "$STATE_FILE"
```
---
## If Both Values Exist — Verify Reachability
```bash
HTTP_STATUS=$(curl -s -o /dev/null -w "%{http_code}" \
-H "Authorization: Bearer $ARTHUR_API_KEY" \
"$ARTHUR_ENGINE_URL/api/v2/tasks?page=0&page_size=1" 2>/dev/null || echo "000")
echo "HTTP_STATUS=$HTTP_STATUS"
```
- `200` → confirm reuse with user, then exit this skill (engine step done)
- `401` → engine reachable but key is wrong; ask user to re-enter API key, update state, then exit
- anything else → engine unreachable; proceed to setup below

How to install
mdr add arthur-ai/arthur-engine/arthur-onboard-oss-engine@sha256:dff68e070b0f26b3The 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.
