changelog-scan skillA
changelog-scan is agent-read markdown (skill) from fusengine/agents: Use when checking for new Claude Code versions, features, or changes since the last known release..
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.
