Add define_tool_block! and define_simple_tool_block! macros to eliminate repetitive boilerplate in tool block definitions. Each tool block now only needs to specify the custom header rendering logic. Refactored blocks: - ShellBlock, ReadFileBlock, WriteFileBlock, EditFileBlock - FetchUrlBlock, FetchHtmlBlock - ListAgentsBlock, GetAgentBlock - ListBackgroundTasksBlock, GetBackgroundTaskBlock The macros generate: - Struct definition with standard fields - new() and from_params() constructors - Full Block trait implementation - Common render() structure (status, approval, result, denied) This reduces ~870 lines of duplicated code to ~410 lines, with tool blocks now being ~15-30 lines instead of ~70-100 lines each. https://claude.ai/code/session_015xi85mutXbrHDKCU9WS511
