Belay turns your Claude Code and Codex sessions into lessons your agent carries into the next one. It reads the history already on your disk, finds what kept going wrong, and proposes lessons backed by the exact turns. You review and approve each one. At the start of the next session, your agent is shown the approved lessons as a Mission Pack and must ask before using them. Belay never edits your project files. Local, encrypted, no account, MIT engine.
