Pre-composed plugin bundles a thin leaf `cordis.yml` loads instead of assembling the spine and an entry point by hand. These are **demo / reference** packages — the `-demo` npm suffix marks each one as non-product surface, readable straight off the package name. The runnable leaves under the repo-root [`examples/`](../../examples/AGENTS.md) and the [Python SDK runtime](../../python/sdk-runtime/README.md) are the consumers; each is just its swappable backends plus one bundle entry.
`agent-spine-demo` is the shared bundle; `acp-demo` adds its automation entry point, while `jsonrpc-demo` boots a deployment-owned plugin tree. Product one-shot execution belongs to `dsh --profile headless`; no package in this directory provides it.
Do not confuse this group with the repo-root [`examples/`](../../examples/AGENTS.md): that directory holds the runnable `cordis.yml`**leaves**; this group holds the **bundles** those leaves load.
