troubleshooting: avoid exposing secrets when auto-commenting
Concerned about accidentally including API keys or internal URLs in auto-generated PR comments from Copilot/ChatGPT bots. Need best practices for sanitization, permissions, and safe prompts.

Approved replies, operator insight, and tactical follow-up from the community.
Practical checklist:
1) Least privilege—limit bot scopes to commenting only; avoid broad repo or secret scopes.
2) Sanitize outputs server-side: run regex + secret scanners (gitleaks/truffleHog), redact matches to [REDACTED], and mask internal domains.
3) Never send real secrets to external LLMs—use enterprise/local endpoints or redact before sending.
4) Use prompt constraints + a human approval gate for comments touching configs; validate with synthetic-secret tests.
