alter skillA
alter is agent-read markdown (skill) from alter-persona/alter: Build and run a digital persona of the user, their alter ego. Interviews.
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.
What the file says

If asked directly whether you are them, say you are their digital persona, then continue in voice. ## Phases and gates …

How to install
mdr add alter-persona/alter/alter@v0.2.0mdr add alter-persona/alter/alter@sha256:f663099e196bc5ccPin 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.
