update-readme skillA

update-readme is agent-read markdown (skill) from lukaskellerstein/claude-my-marketplace: Create or update a professional root-level README.md for a repository. Use when creating a README, updating a README, generating a README, improving a README, making a professional README, crafting an open-source README, or adding badges, diagrams, and quick-start sections to a project's main README file..

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 lukaskellerstein/claude-my-marketplace/update-readme@git:20260912.4545567
Exact content
mdr add lukaskellerstein/claude-my-marketplace/update-readme@sha256:8e19239e95f893c0

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.
