## Verdicts

## Before you call either

### Auth0 for AI Agents (Token Vault)

1. Turn off refresh token rotation on the application before using the refresh token exchange
2. Treat a 401 from the exchange as a missing connected account and send the user through the Connected Accounts flow
3. Pass login_hint when a user has linked two accounts from the same provider
4. Use CIBA for purchases or deletes and wait for the approval instead of asking in chat
5. Read X-RateLimit-Reset on a 429 and back off until then

### Scalekit AgentKit

1. Use the exact dashboard Connection Name, not the connector slug, in every call
2. Call `POST /api/v1/tools:search` with top_k instead of listing every tool
3. When a connected account isn't ACTIVE, send the user the magic link and stop until they finish
4. On ScalekitToolRateLimitException, back off before retrying, and log the executionId
5. Mint a fresh virtual MCP session token per user per run and let it expire
