Persistent memory and a growing knowledge tree for CLI agents — an installable engine, kept separate from your notes, that updates itself
Skill Claude CodeCodex
Turn what was just worked out into a C Brain note — filed in the right zone, linked to what it relates to, indexed. Use when the user says "remember this", "save that", "note it down", "distill this session", or when a non-obvious problem has just been solved and the reasoning would otherwise be lost.

Check the health of the C Brain installation and trunk — dead links, unindexed notes, broken hooks, stale state. Use when recall seems to return nothing, when notes are not being saved, when the user says C Brain "is not working", or before trusting the trunk for something important.
Skill Claude CodeCodex
Search the C Brain trunk for notes relevant to a subject, and read the ones that matter. Use when the user asks what they already know about something, wants past decisions on a topic, says "did we solve this before", "what do I have on X", "check my notes", or when a task smells like something already worked out once.
