 name: setup-tasks
+author: ours
 version: 1.0.0
 description: Creates or migrates a project's `.tasks/` board to the canonical layout — `STATUS.md` (the board, with emoji status legend) plus per-task `<task-slug>.md` files for each active or paused task. Use when the user says "set up tasks", "init tasks", "настрой таски", "инициализируй таски", "create task tracking", "migrate tasks to canon", "tasks broken", or whenever `using-tasks` detects a missing or non-canonical `.tasks/`. Two modes — greenfield (no `.tasks/`) and migrate (existing flat STATUS.md without per-task files). Confirmation gate before writing. Cross-platform.
