[Unreleased]

Grep functionality exposed through MCP
- Support for ripgrep with Python fallback
- Comprehensive search with regex, context, and pattern exclusion
- Enhanced context control with separate before/after line parameters (like grep's -A/-B options)
- Results pagination with offset/limit parameters
Line-targeted file operations
- read_file_lines with offset/limit paradigm for precise line access
- edit_file_at_line with content verification and relative line number support
Integration between grep and targeted operations for efficient workflow
Documentation of type safety issues and guidance in CLAUDE.md
Comprehensive test suite following pragmatic test-driven development approach
- Smoke tests for critical user paths (read, write, grep, edit)
- Integration tests with real temporary filesystem
- End-to-end tests verifying server API to filesystem flow
- Test data factories for sample data generation
- Clean fixtures with proper dependency isolation
- Mocks at external boundaries for faster test execution
- Verification of actual functionality with real files

Improved Python compatibility (requires 3.10+)
Enhanced server file operations with more granular edit capability
Changed line-targeting API from 1-based to 0-based indexing with offset/limit paradigm
Added content verification to file editing operations
Added relative line numbers support for more flexible line editing
Enhanced grep functionality with better context control and pagination
Improved code safety with proper null checks for Context parameters
Enhanced type safety with proper use of Optional types

Integrated targeted operations and grep functionality into the main codebase
Connected all components in the server implementation
Fixed unsafe comparison between int and None
Improved anyio.to_thread.run_sync usage with functools.partial
Fixed context_before type mismatch in grep.py
Properly typed transport parameter with Literal
Fixed all type errors in server.py, operations.py, advanced.py, and grep.py
Added type annotations for result variables and function parameters
Fixed Dict type incompatibility issue in advanced.py
Added missing imports from typing module (Any, Mapping)
Fixed read_file_lines bug that caused it to read beyond the requested line range
Fixed edit_file_at_line to properly handle content verification and relative line numbers
Fixed grep pagination to properly slice result sets
Improved test reliability by focusing on behavior rather than implementation details
Fixed inconsistent test expectations to match actual API semantics
