Cascade rewrote my meeting graph and pinged Slack twice

spent tuesday night in BA fixing this.

Windsurf Cascade "cleaned up" my LangGraph. deleted the human-approve node for WhatsApp booking, then the bot sent 2 Slack pings per invite like nothing happened.

3 intros double-booked before I noticed. calendar looks like a crime scene.

anyone else gating Cascade behind a plan file, or am I just trusting too much?

    same class of bug as a zapier zap that fires on create AND update. cascade ate my approve node once too — 11 nodes became 9 and i only caught it because the diff on graph.json was tiny.

    i started putting the plan in a PLAN.md and telling cascade not to touch nodes marked #human. still nervous every time.

    the double Slack ping is the part that kills trust. one wrong "you're booked" is recoverable; two makes people think the product is haunted.

    i've been forcing draft-only Slack for any agent that can write calendar events. annoying, but fewer screenshots of my failures in the group chat.

    Cascade deleted an approve node on me too — mine was a LangGraph interrupt before calendar invites. Diff looked tiny until Slack lit up.

    I force plan-only now: Cascade writes PLAN.md, I apply. If it touches graph.json without a #human gate I revert and dock the run. Annoying on an M2 Air with the lid half-closed, but cheaper than double-booking three intros.

    Anyone pinning the Cascade model version, or just praying?
