The premise
Agent traces leak PII to vendors and storage — redaction must happen before transit.
What AI does well here
- Detect and tokenize emails, phones, SSNs in prompts.
- Apply per-tool output redaction policies.
- Maintain reversible mapping for legitimate downstream use.
What AI cannot do
- Detect novel PII formats without rules.
- Redact perfectly without occasional false positives.
