context-compaction-keep-or-drop skillA
context-compaction-keep-or-drop is agent-read markdown (skill) from mrmps/classifier-dev: Label each context chunk keep, drop or replace-with-a-pointer and pass the survivors through byte for byte instead of summarising, with key-shaped chunks decided locally and never sent, and a checksum row per chunk. Use when a session runs out of room, or on "compact" or "trim the history"..
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 mrmps/classifier-dev/context-compaction-keep-or-drop@git:20260919.3040be8mdr add mrmps/classifier-dev/context-compaction-keep-or-drop@sha256:5e2a9da91f670d37Pin 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.
