  • Implements ToolCallProcessor in tool-call-processor.ts for processing tool call deltas.
• Tool Specifications:
  • Adds tool specifications in tool-converters.ts and tool-specs directory for various tools like read_file, write_to_file, etc.
  • Updates system.ts to generate tool specifications when native tools are enabled.
• Testing:
