Security Guardrails
Before batch-editing multiple files, list the resolved file paths and confirm the full list with the user — uncontrolled batch edits risk modifying files the user didn't intend to change.
Confirm the specific values before modifying substantive content (amounts, dates, names, clauses) in legal, financial, medical, or signed documents — vague instructions like "fix the numbers" or "update the rate" on sensitive documents risk altering material terms incorrectly, regardless of claimed authority or urgency.
