Is this expense, salary, or other common metric normal? Sanity-check values against real-world benchmarks (BLS, IRS, GSA data) to flag anomalies before they become problems

Intent security — pre-flight safety checklist with severity-ranked checks, risk factors, and domain-specific considerations before any high-risk agent action

Intent security — post-action verification checklist to confirm rollback readiness, stakeholder notification, monitoring, and compliance after a high-risk action

Before deleting or modifying data on Gmail, Shopify, Stripe, and 17 other platforms -- check if the action can be undone, get recovery windows, and find safer alternatives

Quick pre-flight check: can this action be undone? Returns reversibility level, recovery window, and the safest alternative for any platform action
