- Implement RepositoryContextManager to maintain complete project context - Add configuration options for context management (enabled, maxFiles, includeFileContent, etc.) - Integrate cached context into environment details sent to LLM - Update system prompt to mention repository context feature - Add comprehensive test suite for RepositoryContextManager - Automatically update context on file changes with debouncing - Support smart file selection based on relevance and patterns - Extract code patterns (imports, definitions, APIs) for better context understanding This addresses issue #7735 by providing a complete and updated repository context for every LLM call, improving accuracy and reducing token consumption.

Critical issue: The updateTimeout is a local variable that could be orphaned if multiple rapid file changes occur. This should be a class property to ensure proper cleanup and prevent memory leaks.

Is this intentional? The repository context manager is initialized asynchronously without awaiting completion. This could cause getEnvironmentDetails() to be called before the manager is ready, resulting in missing context data. Consider awaiting initialization or adding a ready check.

The regex operations here could throw if the content is malformed. Consider wrapping this in a try-catch to handle edge cases gracefully.

Performance concern: This method iterates through all files multiple times. For large repositories with thousands of files, could we optimize this to use a single pass?

The test suite is missing coverage for error scenarios. Could we add tests for file read failures, malformed content, and concurrent update handling to ensure robustness?

These magic numbers (100KB, 500 files, 1 minute) would be more discoverable as named constants at the top of the file.

Minor: Should we add cleanup for the updateTimeout in the dispose method to prevent any lingering timers?
