Pre-composed plugin bundles for tests and custom deployments that need the concrete Agent spine without assembling it by hand. The -demo npm suffix marks each package as support infrastructure rather than a product interface.

Package	npm name	Role
`agent-spine-demo/`	`@deepseek-ai/dsh-agent-spine-demo`	Reusable agent-spine bundle

agent-spine-demo is the shared bundle. Product SDK, ACP, and one-shot execution belong to dsh --profile sdk / dsh --profile sdk-minimal, dsh --profile acp, and dsh --profile headless; no package in this directory provides an application entry.

These packages are not product API. Product seams and entry points remain in their owning groups; support bundles select concrete compositions for focused consumers.
