Agent-framework recipes (CrewAI / AutoGen / OpenAI Swarm / MCP agent)

[WaylandYang]

Item 5 of meta #112. 2-3 weeks; adoption track.

recipes/langgraph-react/ exists. Add 3-5 more, each a 2-3 day landing-page-grade demo of "spawn agent → run a few steps → BRANCH the running state → fan out N children → compare results."

Candidates (pick 3-5)

• recipes/crewai-fanout/ — CrewAI multi-agent crew, BRANCH after task assignment, parallel execution
• recipes/autogen-branch/ — AutoGen GroupChat, BRANCH after a fork-worthy turn
• recipes/openai-swarm/ — Swarm handoff demo with BRANCH at handoff time
• recipes/mcp-agent/ — Claude / GPT agent talking to forkd-mcp itself (closes loop with MCP server — wire forkd's BRANCH + sandbox API as MCP tools #113)
• recipes/playwright-browser/ — speculative browsing: BRANCH a browser state, try N navigations in parallel
• recipes/postgres-fixture/ — database state fan-out (already in scaffold; finish)

Per-recipe checklist

• build.sh produces the rootfs
• README.md with the why + a 30-second cast
• One Python script demonstrating end-to-end
• Optional: pre-built snapshot pushed to the Hub

Acceptance

3-5 recipes complete, each with a working demo. Pinned in main README's "Try it" section.
