Greptile Summary

This PR adds a Google Translate integration with two operations: translate text and detect language. The implementation uses Google Cloud Translation API v2 with API key authentication passed as a query parameter (the correct method for this API).

Implements google_translate_text tool for translating text between languages with optional source language auto-detection
Implements google_translate_detect tool for detecting the language of input text
Adds comprehensive block configuration with 33 target language options and 17 source language options
Includes complete documentation with input/output parameter tables
Follows project patterns for tool configuration, API key visibility (user-only), and error handling
Properly registers tools and blocks in alphabetical order in registries
Adds Google Translate icon SVG to both app and docs

The documentation already addresses the missing input parameters issue mentioned in previous threads.

Confidence Score: 5/5

This PR is safe to merge with minimal risk
Clean implementation following established patterns, proper TypeScript types, correct API key visibility, appropriate error handling, and comprehensive documentation
No files require special attention

Source language dropdown missing 18 languages from target

Medium Severity

The source language dropdown only has 16 language options (English through Polish), while the target language dropdown has 34 options. This appears to be an accidental truncation — 18 languages (Swedish, Thai, Vietnamese, Indonesian, Ukrainian, Czech, Greek, Hebrew, Romanian, Hungarian, Danish, Finnish, Norwegian, Bengali, Malay, Filipino, Swahili, Urdu) are available as targets but not as explicit source languages. Users translating from these languages can't specify them and must rely on auto-detect.

+      const url = new URL('https://translation.googleapis.com/language/translate/v2')
+      url.searchParams.set('key', params.apiKey)
+      return url.toString()


Missing .trim() on API key, unlike other Google tools

Low Severity

The params.apiKey value is used without .trim() when constructing the API URL. Every other Google API tool in the codebase (Google Maps, Google Books, etc.) consistently calls params.apiKey.trim() before setting the key in the URL. This inconsistency means whitespace in the API key input could cause authentication failures only for Google Translate.
