Clay Seal vs Stele

Runtime security for AI agents. Clay Seal narrows what an agent can do as the task changes. Open-source identity and receipts; design-partner runtime sandbox.

Shared memory for AI coding agents. Claude Code, Cursor and Codex read what your project already decided, so context survives between tools and sessions.

About Clay Seal

Runtime security for AI agents. Clay Seal narrows what an agent can do as the task changes. Open-source identity and receipts; design-partner runtime sandbox. Each action is checked against what the task needs now, not what the agent received at launch. The permissions an agent starts with are a guess about everything it might ever need. The walls move in as the task takes shape, and anything that reaches outside them is blocked, no matter what the original grant allowed.

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.
