PR Review: Fix CI failures in retry.ts

Todo List:

• Read the changed file (src/utils/retry.ts)
• Analyze the git diff to see the specific change made
• Review code quality and potential issues
• Check for documentation consistency
• Provide comprehensive review feedback

Review Summary

This PR successfully fixed a syntax error in src/utils/retry.ts by removing a malformed console.log statement that had an unterminated string literal. The fix resolved both prettier formatting and TypeScript compilation failures.

Code Quality Analysis

✅ Positive Aspects

1. Clean Implementation: The retryWithBackoff function is well-structured with clear separation of concerns
2. Good Type Safety: Proper TypeScript types with generic support (<T>) and well-defined options interface
3. Sensible Defaults: Default values are reasonable (3 attempts, 5s initial delay, exponential backoff)
4. Error Handling: Proper error propagation and type checking for error instances
5. Usage: Function is actively used in critical components (github/token.ts for GitHub API calls and mcp/github-file-ops-server.ts for file operations)

📝 Suggestions for Improvement

1. Console Logging Concerns (src/utils/retry.ts:24, 28, 31, 38):

   console.log(`Attempt ${attempt} of ${maxAttempts}...`);
   console.error(`Attempt ${attempt} failed:`, lastError.message);

   Recommendation: Consider making logging optional or using a proper logging framework instead of direct console calls. This could be controlled via an optional silent parameter in RetryOptions.

2. Enhanced Error Context:
   The current error handling could benefit from preserving more context about the retry attempts:

   // Consider adding retry metadata to the final error
   const enhancedError = new Error(`${lastError.message} (failed after ${maxAttempts} attempts)`);
   enhancedError.cause = lastError;
   throw enhancedError;

3. Jitter Support: For production systems, consider adding optional jitter to prevent thundering herd problems:

   const jitterMs = jitter ? Math.random() * 1000 : 0;
   await new Promise((resolve) => setTimeout(resolve, delayMs + jitterMs));

🔒 Security & Best Practices

• No security issues identified
• Error messages are safely handled without exposing sensitive information
• No potential for resource leaks or infinite loops

📚 Documentation Consistency

• No documentation updates needed - this is a utility function that doesn't affect user-facing features
• The function signature and types are self-documenting
• Usage examples exist in the actual implementation files

🎯 Architecture Assessment

The retry utility follows good architectural principles:

• Single Responsibility: Does one thing well (retry with exponential backoff)
• Reusability: Used across multiple critical components for GitHub API reliability
• Configurability: Flexible options while maintaining sensible defaults
• Error Transparency: Doesn't swallow errors, maintains original error context

Overall Assessment

This was an excellent quick fix that resolved the immediate CI issues. The underlying retry implementation is solid and follows TypeScript best practices. The function serves a critical role in handling GitHub API reliability for both authentication and file operations.

Grade: ✅ Approved - Clean fix that restored code quality without introducing any regressions.
