 "title": "Scan screenshots and PDFs for keys before upload",
 "page_title": "How to scan screenshots and PDFs for keys before upload with Preflight",
 "summary": "Let Preflight decode images and PDFs locally, run OCR, and sanitize them before inference.",
 "who": "A developer who attaches screenshots or PDF exports to an agent session and may not notice a key visible in the image.",
 "problem": "Attachments are a common path for secrets, and a key in a screenshot is easy to miss.",
 "outcome": "Attachments are decoded and OCR'd locally, and supported sanitization rewrites them before the model receives them.",
 "steps": [
  "Start the proxy with `nix run github:ghuntley/preflight -- serve`",
  "Point the harness at `http://127.0.0.1:8081/v1`",
  "Attach a screenshot containing a test key from <test-file> and send a prompt about it",
  "Check the logs for an `attachment.inspected` event with `rebuilt: true` when a rewrite happened",
  "Confirm that a finding without a safe replacement returns an error rather than forwarding"
 ],
 "agent_prompt": "Using the preflight repo at github.com/ghuntley/preflight, run the proxy with default settings, attach the image <test-file> containing a fake key to a request, and report the response status and the attachment.inspected log event. Verify that the forwarded attachment no longer shows the key or that the request was rejected.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "Attachments that cannot be sanitized are blocked, and PDF page blacking out is off unless allow_page_redaction is set to true.",
 "category": "Software and DevOps",
 "tags": [

 "lang": "rust",
 "requirements": [
  "A running underclass instance on 127.0.0.1:8080",
  "Nix (for `nix run`) or devenv and Cargo for a local checkout",
  "A coding harness or client that can change its base URL to http://127.0.0.1:8081/v1",
  "Bubblewrap available for the default sandboxed attachment workers"
