Remove external script from index.html to resolve checkFeature is not defined ReferenceError.

The ReferenceError: checkFeature is not defined was caused by an external gptengineer.js script included in index.html that expected a global checkFeature function, which was not defined in our application. Removing this script resolves the error.

Walkthrough

Removed external GPT Engineer script references from index.html, switching bootstrapping to the local /src/main.tsx. Enhanced decryptMessage error handling in src/lib/message-encryption.ts to distinguish OperationError, logging a specific warning while retaining the same return on failure.

Changes

Cohort / File(s) Summary of Changes
Bootstrapping cleanup
index.html
Removed modulepreload and script tags for https://cdn.gpteng.co/gptengineer.js; page now boots solely via /src/main.tsx.
Decryption logging refinement
src/lib/message-encryption.ts
In catch block, cast error to Error; if err.name === 'OperationError', log a targeted warning about likely key mismatch/corruption; otherwise log as before. Return value on failure unchanged.

Poem

I nibbled the scripts, trimmed the fluff,
Hopped to local seeds—no CDN stuff.
When ciphers balk with a stern “OperationError,”
I flick my ears, log clearer terror.
Keys align, carrots shine—
Bugs hop away, the code’s divine. 🥕✨

Pull Request Review

Reviewing PR #63 that removes external script references and handles message decryption errors.

Todo List:

  • Read repository guidelines (CLAUDE.md)
  • Analyze index.html changes
  • Review package-lock.json additions
  • Examine message-encryption.ts modifications
  • Assess security implications
  • Check for potential bugs and performance issues
  • Provide comprehensive feedback

Review Summary

This PR makes two main changes:

  1. Removes external GPT Engineer script references from index.html
  2. Improves error handling in message decryption functionality
  3. Adds package-lock.json (16,744 lines added)

Detailed Analysis

✅ Positive Changes

Security Improvement (index.html:30,132)

  • EXCELLENT: Removal of external script https://cdn.gpteng.co/gptengineer.js eliminates:
    • Potential XSS attack vectors from external domains
    • Dependency on third-party CDN availability
    • The ReferenceError: checkFeature is not defined mentioned in PR description
  • Both modulepreload and script tag properly removed
  • No broken references remain

Enhanced Error Handling (message-encryption.ts:194-199)

  • GOOD: More granular error handling for OperationError specifically
  • Distinguishes between crypto operation failures vs other errors
  • Uses appropriate logging levels (console.warn vs console.error)
  • Maintains user experience by returning [Decryption Failed] placeholder

Dependency Lock (package-lock.json)

  • GOOD: Addition of lockfile ensures reproducible builds
  • Critical for security - pins exact dependency versions

🔍 Security Analysis

Enhanced Security Posture:

  • Removing external scripts reduces attack surface significantly
  • No more dependency on cdn.gpteng.co domain
  • Follows principle of least privilege by removing unnecessary external resources
  • Message encryption implementation remains robust with proper error boundaries

No Security Concerns Identified:

  • Error handling changes don't expose sensitive information
  • Failed decryption still returns safe placeholder text
  • Input validation and cryptographic operations unchanged

🐛 Potential Issues

Minor Considerations:

  1. Missing Context: The removed GPT Engineer script may have provided some functionality that's now lost - ensure no features are broken
  2. Error Granularity: While the OperationError handling is good, consider if more specific error types should be handled differently
  3. Package Lock Timing: Large package-lock.json addition suggests dependency changes - ensure all team members run npm install to sync

⚡ Performance Impact

Positive Performance Effects:

  • Reduced Bundle Size: Removing external script reduces page weight
  • Faster Page Load: One fewer HTTP request to external domain
  • Better Caching: No dependency on external CDN cache policies
  • DNS Resolution: Eliminates DNS lookup for gpteng.co domain

🧪 Testing Recommendations

Suggested Tests:

  1. Verify no JavaScript errors in browser console after script removal
  2. Test message encryption/decryption still works correctly
  3. Confirm OperationError scenarios trigger appropriate warning logs
  4. Validate application functionality that may have depended on removed script

📝 Code Quality

Excellent Practices Demonstrated:

  • Clean removal without leaving dead code
  • Proper error type checking with type assertion
  • Appropriate use of console methods for different error severities
  • Maintains existing code structure and patterns

Final Recommendation: ✅ APPROVE

This is a high-quality security improvement that:

  • Eliminates external script dependency and associated risks
  • Improves error handling without breaking functionality
  • Follows security best practices outlined in CLAUDE.md
  • Has positive performance implications

The changes are focused, well-implemented, and align with the repository's security-first approach.

196-196: Avoid hinting at specific root causes in logs

To reduce information leakage, keep user/device-key specifics out of logs. Consider a neutral message (optionally gated to dev builds).

Apply this diff:

-      console.warn('Message decryption failed (OperationError). Likely wrong device/user key or corrupted data.');
+      console.warn('Message decryption failed (OperationError).');

Optionally, also handle other common WebCrypto DOMException names (e.g., "InvalidAccessError", "DataError") similarly.
