jevmem: automatic project memory for Claude Code

After every Claude Code message, Jev decides in ~0.3 s whether it holds a decision, rule or bug worth keeping, and jevmem saves it as one line in JEVMEM.md.

Automatic project memory for Claude Code. Also works with Cursor and Codex.

**Now in Anthropic's Claude plugin directory:** in the Claude app, Plugins → Discover → jevmem → Add, then follow [the setup steps](#from-the-claude-plugin-directory).

## What it does

- Saves decisions, constraints, bugs, todos and dead ends (an approach that was tried and failed, with the reason) from your Claude Code chats into `JEVMEM.md`, automatically.
- When you change your mind, the old line is marked superseded, not deleted.
- Next session, the relevant lines are added to Claude's context.
- Checks lines added by others before they're added to Claude's context.
- Checks Bash, Edit and Write calls against your saved rules before they run, and has Claude Code ask you when one may be broken (the guard, 0.6.0).

Real lines from 0.5.7's default writer, which 0.5.8 to 0.5.10 did not change ([the run](results/readme-example-2026-09-26.txt), 2026-09-26). It kept one sentence of each turn: the Postgres turn also said "SQLite locks up under concurrent writes", and that reason was left out. Since 0.6.0 the line is made from th
