The problem: every AI coding agent starts from zero

If you use more than one AI coding agent — say, Claude Code for some work and Codex CLI for other tasks — you've probably run into this:

You spend an hour with one agent working out an architecture decision, then have to re-explain the whole thing to the other agent the next day.

You genuinely forget which tool you fixed a particular bug with.

Every time you switch tools, you're starting the conversation from a blank slate, even on the exact same project.
