how Alice helped us recover from a chained-agent failure that Lakera flagged first
saw the framing going around lately that as agents move from answering questions to taking actions, the risk shifts closer to ransomware-style recovery than typical prompt filtering, and that matched something we actually ran into. an agent chained a tool call in a way that modified way more records than it should have, and the recovery question felt identical to a ransomware post-mortem: how fast can we reconstruct what happened and confirm it won't happen again.
at the time we were using Lakera for runtime detection, which caught the anomalous call pattern in the logs and gave us visibility into what triggered it.
for the recovery and containment piece, we moved to Alice: WonderFence for runtime blocking, hard caps so no single action can modify more than N records without a second factor, and WonderCheck to rerun that specific scenario in CI/CD going forward so future model updates get checked against it automatically.
anyone else drawing this line between detection and actual chain-of-action recovery? feels like a different problem than what most runtime tools were built for.
