Hello Swarm

The smallest workspace that exercises every piece of the mental model.

# Validate the workspace
swarmkit validate examples/hello-swarm/workspace --tree

# Run it (needs a model provider)
SWARMKIT_PROVIDER=openrouter SWARMKIT_MODEL=meta-llama/llama-3.3-70b-instruct \
  swarmkit run examples/hello-swarm/workspace hello \
  --input "Greet the engineering team"

The topology has a root supervisor and a greeter worker. The greeter calls the hello-world MCP server's greet tool — a FastMCP server that lives alongside the workspace.

See examples/hello-swarm/README.md for the full walkthrough.
