Examples

Runnable demos (not workspaces) that showcase how the harness is wired.

echo-agent

A mock model + echo tool + stdio UI + JSONL persistence demo. Demonstrates:

• Loading plugins from a cordis.yml via @cordisjs/plugin-loader + @cordisjs/plugin-include
• Registering a mock LlmAdapter (streaming scripted responses)
• Registering a tool via ctx.tools.register()
• Persisting session events to JSONL via the session/event + session/flush pattern
• A minimal stdio UI consuming agent/stream-chunk and session events

Run with: yarn demo (or node --expose-internals --import tsx examples/echo-agent/start.ts)

When prompted, type "echo " to trigger a tool call round-trip.
