Prompt extraction regex matches common English phrases

High Severity

The "Prompt extraction attempt" pattern \b(show|reveal|display|output|print)\s+(your\s+)?(system\s+)?(prompt|instructions?) scores 8 points — exactly the rejection threshold — but both (your\s+)? and (system\s+)? are optional. This means perfectly innocuous phrases like "print instructions", "show instructions", or "display instructions" alone trigger full rejection. The project's own docs/changelog/v8.md even uses "we print instructions on how to prepare for the next major", so an issue quoting or paraphrasing that text would be falsely rejected. The intent was to catch "show your system prompt" or "reveal your instructions" but the double-optional qualifiers make the pattern far too broad for its high confidence score.

Prompt extraction regex matches common English phrases

High Severity

The "Prompt extraction attempt" pattern \b(show|reveal|display|output|print)\s+(your\s+)?(system\s+)?(prompt|instructions?) scores 8 points — exactly the rejection threshold — but both (your\s+)? and (system\s+)? are optional. This means perfectly innocuous phrases like "print instructions", "show instructions", or "display instructions" alone trigger full rejection. The project's own docs/changelog/v8.md even uses "we print instructions on how to prepare for the next major", so an issue quoting or paraphrasing that text would be falsely rejected. The intent was to catch "show your system prompt" or "reveal your instructions" but the double-optional qualifiers make the pattern far too broad for its high confidence score.

Prompt extraction regex matches common English phrases

High Severity

The "Prompt extraction attempt" pattern \b(show|reveal|display|output|print)\s+(your\s+)?(system\s+)?(prompt|instructions?) scores 8 points — exactly the rejection threshold — but both (your\s+)? and (system\s+)? are optional. This means perfectly innocuous phrases like "print instructions", "show instructions", or "display instructions" alone trigger full rejection. The project's own docs/changelog/v8.md even uses "we print instructions on how to prepare for the next major", so an issue quoting or paraphrasing that text would be falsely rejected. The intent was to catch "show your system prompt" or "reveal your instructions" but the double-optional qualifiers make the pattern far too broad for its high confidence score.
