AI-Context Firewall & Secret Redactor Plugin

A local proxy or IDE extension that acts as a firewall between the developer's local filesystem and AI coding assistants. It scans all file chunks for secrets (using regex/entropy) *before* they are uploaded to remote embedders or context windows, guaranteeing zero secret leakage.

Real quotes from Reddit comments that inspired this opportunity

  • Cursor's autocomplete spited out those account details.
  • Autocomplete that can touch secrets at all is the wrong default.
  • Holy fucking yikes. Typical of the irresponsible speed-at-all-cost AI mindset
