v2.0.0 - Complete File Editing Overhaul

v2.0.0 - Complete File Editing Overhaul

🎉 Major Release - This release represents a complete rewrite of the file editing interception system based on deep reverse engineering of the Augment VS Code extension (v0.778.0).

✨ New Features

Advanced str-replace-editor Implementation

• Multi-entry replacements: Support for old_str_1/new_str_1, old_str_2/new_str_2, etc. (up to 20 entries)
• Three-tier matching algorithm:
  1. Exact verbatim matching
  2. Line number-based disambiguation (with 20% tolerance)
  3. Basic fuzzy matching (trimmed line matching)
• Insert command support: insert command for adding content at specific line numbers
• Line ending preservation: Automatically detects and preserves original line endings (CRLF/LF)

Unified Tool Interception Architecture

• All providers now support interception: Anthropic, OpenAI, and Google providers all use the same interception logic
• Proper result handling: Intercepted tool results are correctly returned to the AI as tool_result_node (type 1)
• Consistent behavior: All providers now handle file editing tools identically

🔧 Improvements

edit-file Tool Handling

• Changed from conversion to error: Previously converted to view tool (wasting a round trip)
• Now returns clear error: Instructs AI to use str-replace-editor instead
• Better user experience: AI immediately knows to use the correct tool

Provider-Specific Enhancements

• Anthropic provider: Added convertOrInterceptFileEdit call in tool_use completion handler
• Google provider: Added fixToolCallInput and convertOrInterceptFileEdit in functionCall handler
• OpenAI provider: Fixed intercepted result handling to return tool_result_node instead of null

🐛 Bug Fixes

• Fixed issue where intercepted tools would not return results to the AI
• Fixed single-replacement limitation in str-replace-editor
• Fixed missing line number disambiguation
• Fixed lack of fuzzy matching fallback

📚 Technical Details

Based on reverse engineering analysis of Augment extension's implementation:

• PC class (str-replace-editor): Complete implementation including handleStrReplace, handleInsert, singleStrReplace
• g$e class (edit-file): Server-side API call mechanism
• Checkpoint system: addCheckpoint() → qt().writeFile() → WorkspaceEdit.replace()
• Line ending handling: OD() normalization, JX() detection, sUe() restoration

🔄 Breaking Changes

• edit-file tool now returns an error instead of converting to view
• processToolCallForAugment now returns tool_result_node for intercepted tools instead of null
