remember — Claude Code plugin: what it does, how to install
Hooks save your Claude sessions, compress them through Haiku into daily summaries, and load the history back into context at session start.
/plugin install remember@claude-plugins-official

The plugin hooks into the Claude lifecycle. save-session.sh fires during work, a Python script extracts the session, Haiku summarizes it, and the result lands in now.md. From there it compresses in layers: hourly compression produces today-YYYY-MM-DD.md, daily consolidation produces recent.md and archive.md. Each layer is shorter than the one above it, so the whole history fits in a small token budget.
At session start the SessionStart hook injects identity.md, the remember.md handoff note from the previous session, now.md, today's summary, recent.md for the last 7 days, and archive.md. Rotated slices archive-YYYY-MM-DD.md and recent-YYYY-MM-DD.md stay out of context but remain searchable. After a compaction only identity.md is injected again, because the rest was already delivered.
You need Python 3.9+, the Claude CLI with Haiku access, Bash 3.2+, and jq. On Windows there is no run without a POSIX shell in PATH — Git Bash, MSYS2, or WSL. Hooks are read at session start, so restart Claude after installing.
