hello-world skillA

hello-world is agent-read markdown (skill) from dcc-mcp/dcc-mcp-core: Example skill — minimal greeting tool demonstrating the dcc-mcp-core skill system. Use only when testing a new skill installation or onboarding to the skill authoring workflow. Not intended for production use..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add dcc-mcp/dcc-mcp-core/hello-world@git:20260723.c79db80
Exact content
mdr add dcc-mcp/dcc-mcp-core/hello-world@sha256:f7a5b37c18cd6fb8

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
