JSON tool-schema definitions for Trae's agentic Builder mode, covering 18 tools spanning task tracking, codebase retrieval, file editing, command execution, and session lifecycle. Notable entries include a 'search_codebase' embedding/retrieval context engine, three distinct editing tools ('write_to_file', 'update_file', 'edit_file_fast_apply') with cost-based selection guidance, and blocking/non-blocking command execution with status polling.
