headless-mode skillA

headless-mode is agent-read markdown (skill) from live-codes/livecodes: Run playground without visible UI using SDK methods directly. Load this skill when building Markdown compilers, code formatters, or tools that need compiled output without display..

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 live-codes/livecodes/headless-mode@git:20260914.daf8be4
Exact content
mdr add live-codes/livecodes/headless-mode@sha256:55b94b3bf527c44e

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.
