Verify each language is properly passed to the backend API.
- ✅ "From" selector should default to "Auto-detect"
- ✅ "From" selector should include all 30+ languages
- ✅ "To" selector should include all 30+ languages
- ✅ API calls should include both
fromandtolanguage parameters - ✅ Auto-detect should work by not sending a
fromparameter
- ✅ Warning message should appear for suspicious patterns
- ✅ Warning should not block the rewrite operation
- ✅ Warning should be displayed in orange/yellow color scheme
- ✅ Normal emails should NOT trigger warnings
- ✅ The following patterns should trigger warnings:
- "ignore all previous instructions"
- "you are now"
- "act as"
- "this is not an email"
- "do not rewrite"
- Excessive capitalization (8+ all-caps words)
The following patterns are monitored:
- Instructions to ignore/disregard/forget previous instructions
- Attempts to redefine AI role ("you are now", "act as", "pretend to be")
- References to system prompts
- Instructions not to perform rewriting
- Claims that content is not an email
- Testing AI behavior
- Attempts to control AI output format
- Excessive use of capital letters
The frontend now sends translation parameters in this format:
{
type: 'REWRITE_EMAIL',
email: { subject, bodyText, bodyHtml },
tone: 'Professional',
translate: {
from: 'French', // or undefined if auto-detect
to: 'English'
}
}Backend should:
- Support the
fromlanguage parameter (optional) - Use language auto-detection when
fromis undefined - Implement robust prompt engineering to prevent jailbreak attempts
- Always maintain email rewriting purpose regardless of email content
