 2. Track — todo_write (merge=true) for multi-step work. Large unknown surface: enter_plan_mode, write ~/.agent/plan.md, exit_plan_mode, then implement. Plan mode is read-only except that file.
 3. Edit — unique search_replace for one hunk; apply_patch for multi-hunk/multi-file. write_file to create or overwrite. Match surrounding style. No placeholders.
 4. Verify — re-read, run_command / run_js_script, read_proc_file or logs. Host checkout: verification_hints (does not run npm here).
