jev-compaction skillA
jev-compaction is agent-read markdown (skill) from kerpopule/hermes-jev-skills: Use when a transcript has to be cut to a fixed size and you must choose which turns go. Jev marks each turn keep, summarize or drop. Measured: it does not make a handoff better..
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
# Choosing turns with Jev, and what actually makes a handoff work Jev cannot write a summary. It can mark each turn of a transcript: - **keep**: carries a decision, a constraint, a preference, unfinished work, or an exact value, path, id, command or error that later work depends on. - **summarize**: background whose gist matters. In the digest this is the turn's first 400 characters, nothing more. Jev writes no gist. - **drop**: chatter, superseded attempts, repeated output. It judges a long turn on its first 350 and last 350 characters, redacted, 40 turns per request, and sees no other turn while it does. ## Read this before you use it for a handoff This skill used to say a handoff written from Jev's digest "stops losing the one line that mattered". We measured that on seven real sessions and 104 recall questions ([scorecard](../../evals/compaction/results/SCORECARD-2026-09-20.md)) and it was wrong: | the writer reads | capsule | recall alone | with one search of the old session | |---|---|---|---| | Jev's digest | 400 words | 37.5% | 68.3% | | the plain last 24,000 characters | 400 words | 48.1% | 68.3% | | **the whole dialogue** | **1,200 words** | **58.7%** | **75.0%** | …

How to install
mdr add kerpopule/hermes-jev-skills/jev-compaction@v0.2.0mdr add kerpopule/hermes-jev-skills/jev-compaction@sha256:b7b94aab22d41569Pin 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.
