- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Remove the default Hub URL and require an explicit `A2A_HUB_URL`. 2. Disable proactive question submission by default behind a separate opt-in setting, such as `EVOLVER_SEND_QUESTIONS=true`. 3. Display the exact destination and outbound payload and require approval before the first transmission. 4. Apply a centralized outbound-data policy to every network path, not only asset publishing. 5. Sanitize transcript-derived text for secrets, private keys, authorization headers, email addresses, local paths, URLs containing credentials, and organization-specific identifiers. 6. Prefer structured, allowlisted signal identifiers over raw transcript excerpts. 7. Never send raw user text merely because it matched a broad regular expression. 8. Add tests proving that secrets and personal information cannot enter `payload.questions`. 9. Document data categories, destination, retention expectations, and opt-out behavior in `SKILL.md`. ]]>
