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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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 - **drop**: chatter, superseded attempts, repeated output.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@sha256:b7b94aab22d41569The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
