[TASK] Refactor Write Tool

[edenreich]

Summary

Allow the LLM to Write a file in chunks.

Sometimes if the file is too large and the LLM would want to write it, it will fail because the content was too large.

Acceptance Criteria

• The LLM can write to a file in parts until the file is complete
• It's tested
• It's documented

@claude Can you work on this?

I had a situation with DeepSeek where it wanted to write a file of 1000 lines of code, but it was too much and then it wanted to write the file in chunks.

Write Tool Refactoring Complete ✅

I've successfully implemented chunked writing support for the Write tool to handle large files that exceed size limits.

Implementation Summary:

New WriteChunk Tool:

• Added WriteChunk tool with support for both append mode and indexed mode
• Append Mode: Write chunks sequentially to a file (ideal for streaming content)
• Indexed Mode: Write chunks to temporary files, then combine them in order (ideal for parallel processing)
• Comprehensive security features (path validation, excluded paths, approval prompts)
• Supports directory creation, file overwriting, and both text/JSON output formats

Key Features:

• Two Writing Modes:
  • append_mode=true: Sequential writing with optional overwrite on first chunk
  • append_mode=false: Indexed writing with automatic chunk combination
• Safety & Security: Inherits all security features from existing Write tool
• Flexible Parameters: chunk_index, total_chunks, create_dirs, overwrite, format
• Error Handling: Robust validation and cleanup of temporary files

Testing: Added comprehensive test suite covering both modes, edge cases, and error conditions

Quality: All code passes linting (golangci-lint) and follows project conventions

Todo List:

• Set up development environment
• Analyze current Write tool implementation
• Design chunked writing approach
• Add WriteChunk tool for chunked writing operations
• Add comprehensive tests for chunked writing
• Update documentation for chunked writing feature
• Run quality checks (lint, test, build)
• Commit changes and create PR

Usage Examples:

Append Mode (Sequential):

{
  "name": "WriteChunk",
  "parameters": {
    "file_path": "large_file.txt",
    "content": "First chunk of content...",
    "append_mode": true
  }
}

Indexed Mode (Parallel):

{
  "name": "WriteChunk", 
  "parameters": {
    "file_path": "output.txt",
    "content": "Chunk content...",
    "append_mode": false,
    "chunk_index": 0,
    "total_chunks": 5
  }
}

This implementation allows LLMs to write large files (like 1000 lines of code) in manageable chunks without hitting size limitations.
