tasks

# Tasks Use the `bb tasks` CLI to understand the assigned task, keep its record useful, and report the outcome where the work is tracked. Delegation presets are user-defined; Tasks ships with none. Before dispatching work, use `bb tasks preset list` and create a preset if the required one does not already exist. Dispatch requires an existing preset. Create or update the same execution selection exposed in the Tasks UI with `--provider`, `--model`, `--reasoning`, and optional `--service-tier default|fast|none`: ```sh bb tasks preset create --name "Codex high" --provider codex \ --model gpt-5.6-sol --reasoning high --service-tier fast \ --permission auto ``` `preset update` accepts the same flags; `--service-tier none` clears a tier. ## Work a task 1. Find and read the task before acting: ```sh bb tasks show ABC-12 ``` The detail includes the description, status, priority, labels, subtasks, comments, attachments, attached worker threads, and the GitHub pull requests those threads produced (from environment metadata, with state open/draft/merged/closed). Use `bb tasks show ABC-12 --json` when the result will drive commands or code. For project-wide discovery, `bb tasks list` returns at most 100 rows by default. Pass `--limit 1-500`; in JSON, continue with `nextCursor` via the same filters/sort and `--cursor <value>`. A task-list mutation makes an old cursor stale, so restart without it. 2.
