Automated README summary
Automatically summarized from the README on 19 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
jevmem keeps a JEVMEM.md file in your repo with decisions, rules, bugs, to-dos and dead ends from Claude Code chats, and brings the relevant lines back next session. Open source (MIT), built on TypeSafe AI's Jev.
How it uses Jev
When you decide something in a chat, jevmem asks Jev, a model that answers yes/no questions with probabilities, whether it's worth keeping. If it is, jevmem writes one line to JEVMEM.md. Next session, the lines that matter for your prompt go back to Claude.
Primitives:choice
Technique worth stealing
Use a yes/no probability model as a cheap filter deciding which chat turns become persistent memory lines.
Try it
npm install -g jevmem, then jevmem setup in your project folder.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
