Agent skill from
When you want to pull in the right AI model for the right job: hand a task to another agent CLI (Codex, Claude, Gemini, Grok, Amp, OpenCode, Cursor, Kiro, Antigravity), or send one prompt to several at once for independent opinions, then synthesize. Delegate mode gives one castmate the job, optionally with write access ('have codex write the migration'). Fan-out mode runs read-only reviews in parallel. Rounds mode lets castmates build on and challenge each other's findings. Calls the official CLIs you already have installed and logged in (Gemini CLI needs an API key on personal accounts); no MCP. Triggers on '/castmate,' 'ask codex,' 'have gemini do this,' 'get a second opinion,' 'what would other models say,' 'fan this out,' 'cross-check this with another model,' 'delegate this to codex.' Advisor personas for founder questions go to maker-council. Personal models, casting rules, and run outputs live in ~/.config/makerskills/castmate/.

1# /castmate — the right model for the right job23You are the host agent. Castmates are other AI coding CLIs installed on this machine. A small script, `scripts/castmate.py` in this skill's folder, runs them. You decide who gets cast, write the prompt, read what comes back, and tell the user what it means.45Adapted from [counselors](https://github.com/aarondfrancis/counselors) by Aaron Francis (MIT). Discovery, prompt writing, and synthesis moved from code into this workflow, and the model list moved into config so it doesn't go stale.67```bash8python3 <skill-dir>/scripts/castmate.py list # castmates, groups, install + read-only status9python3 <skill-dir>/scripts/castmate.py test codex fable # each must reply "OK"10python3 <skill-dir>/scripts/castmate.py run -c codex-sol-high,fable-high -f prompt.md --json11```1213`<skill-dir>` is this skill's install folder. In Claude Code it is the skill's base directory.1415## First run1617**Before the first cast in a session, run `castmate.py test` on the castmates you plan to use.** It takes 5–15 seconds. `list` only shows that a CLI is installed, not that it's logged in or that the account has the model. If nothing is installed, or a test fails, set the user up first. **`references/cli-setup.md` is the setup guide.** Walk through it rather than reciting it:18191. Ask which agent CLIs they already use. One logged-in CLI is enough to start. Suggest Codex if they have none: it's the only one that confines `--write` to `--cwd`.20…
