Your agent forgets everything between sessions. Light gives it notes that survive: plain Markdown in your repository, keyword search over them, and every hit carrying a citation that resolves back to the exact block it came from. Five megabytes, no model to place, no service to run, no configuration to get right first.

$ cbl recall 'postgres data directory'
1. r2-867ef2a8cd01  r2  pg18-moves-pgdata  (100% of top)
     # PostgreSQL 18 moves PGDATA
     The official `postgres:18` image puts the data directory at
     `/var/lib/postgresql/18/docker` instead of `/var/lib/postgresql/data` ...
caveat: search is lexical: it matches the words in the text, not the meaning.

The caveat is not an apology, it is the contract. Light searches for words. It says so on every result, so nobody builds on a search that did not happen.

Install

$ cargo install cyberbrain-light
$ cbl init
$ cbl install          # writes the two hooks into .claude/settings.json
