Greptile Overview

Greptile Summary

Removed legacy manual wrapper classes for AI providers (OpenAI, Anthropic, Mistral, Bedrock, Gemini) in favor of auto-instrumentation approach.

Key Changes:

• Deleted 1,386 lines of manual wrapper code across 5 AI providers
• Updated documentation (CLAUDE.md, README.md) to reflect auto-instrumentation as the primary approach
• Cleaned up comments: replaced outdated "HACK" and "TODO" markers with clear explanations of design decisions
• Removed unused utility functions (get_context(), reset_context_key(), create_paid_callback(), get_audio_duration())
• Updated naming consistency (PaidAgentsHook → PaidOpenAIAgentsHook, PaidCallbackHandler → PaidLangChainCallback)
• Modernized type hints and improved code clarity throughout

The PR maintains backward compatibility for callback/hook integrations (PaidLangChainCallback, PaidOpenAIAgentsHook) which still require manual integration, while removing the now-redundant wrapper classes that have been replaced by OpenTelemetry auto-instrumentation.

Confidence Score: 5/5

• This PR is safe to merge with no risk - it's a clean refactoring that removes deprecated code
• The changes are straightforward code cleanup: removing deprecated wrapper code that has been replaced by auto-instrumentation, updating documentation to match, and improving comment clarity. No tests reference the deleted wrappers, no runtime logic changes, and the remaining callback/hook exports are preserved correctly.
• No files require special attention
