retention skillA
retention is agent-read markdown (skill) from agenttoolkit/altk-evolve: Apply data-retention rules to the local evolve store — flag or delete stale and unused memories and expired sessions (dry-run by default).
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
mdr add agenttoolkit/altk-evolve/retention@git:20260723.976721amdr add agenttoolkit/altk-evolve/retention@sha256:656c674848f6d7e7Pin 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.
