Platform overview

Mini Programs are small apps that run inside Lex: a task board, a calculator, a form that asks the assistant for help. You build them on the contributor platform at platform.lexcetha.com with React and @lex/sdk, and once reviewed they appear in every workspace member's Capabilities catalog.

          Lex API ── checks session, workspace and approved permissions

• Sandboxed. A Mini Program runs in an iframe with no network, no cookies and no access to the page around it.
• Capability-based. It can only do what its manifest declares and a reviewer approved: show notifications, keep private storage, ask the assistant. See Permissions.
• Reviewed and immutable. Every published version is reviewed, stored once and verified by SHA-256 each time it loads.
