Greptile Overview

Greptile Summary

This PR is a Fern-generated SDK update that adds comprehensive logging and security enhancements to the TypeScript SDK.

Key Changes

• Added new logging infrastructure with level-based filtering (LogLevel.Debug, Info, Warn, Error) and silent mode (defaults to silent: true)
• Implemented sensitive data redaction for authorization headers, API keys, tokens, passwords, session IDs, and other credentials
• Added custom fetch function support for platform compatibility
• Extended BaseClientOptions to accept logging and fetch configuration
• Updated all API resource clients to pass logging and fetch options through to the fetcher
• Added support for new request types (form, other) in addition to existing types
• Comprehensive test coverage with 500+ lines of new tests for logging and redaction functionality
• Version bump to 0.1.11, pnpm upgrade to 10.20.0
• Added CONTRIBUTING.md with Fern generator documentation

Changes Impact

• Backward compatible: All new options are optional with sensible defaults
• Security improvement: Automatic redaction prevents credential leakage in logs
• Flexibility: Custom loggers and fetch implementations can be provided
• Well-tested: Extensive test coverage ensures reliability

Confidence Score: 5/5

• This PR is safe to merge with no issues - well-generated code with extensive test coverage
• This is a Fern-generated SDK update that adds valuable logging and security features. The changes are backward compatible (all new options are optional), thoroughly tested (1600+ new test lines), and follow established patterns. The logging defaults to silent mode preventing unexpected console output. The redaction logic protects sensitive credentials from accidental exposure. All API clients are updated consistently.
• No files require special attention
