Delegate tasks to Google's Antigravity CLI (agy) for prototyping, debugging, code review, and research. Supports multi-turn sessions via SESSION_ID. Successor to the retired Gemini CLI.

Delegate tasks to Claude Code CLI for prototyping, debugging, and code review. Supports multi-turn sessions via SESSION_ID.

Delegate tasks to Codex CLI for prototyping, debugging, code review, implementation handoff, cross-model second opinions, and multi-turn Codex sessions via SESSION_ID.

Delegate tasks to Grok CLI (xAI) for prototyping, debugging, code review, research, and cross-model second opinions. Supports multi-turn sessions via SESSION_ID.

Turn a large task into a persistent plan file and a trackable Issue CSV (local files, not an external issue tracker), then execute the issues autonomously with per-row status updates. Use when work must survive across sessions or hand off between agents, when you need an auditable record of multi-step execution, or to resume a plans/ and issues/ pair from an earlier session. Do not use for single-session tasks that your harness's built-in plan or todo tracking already covers.
