About Stele
Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions. Only one of these agents knows this was tried last spring and rolled back. KNOW-142 : a captcha on checkout shipped last spring and was reverted after two weeks. The bot traffic is real, though it spikes on release days and is quiet the rest of the time. A gate armed only during a release window would avoid repeating that.
