A2UI Python core 0.3 and Agent SDK 0.8 rework multi-catalog validation

Event Source published Indexed Verified
Why it matters
Component catalogs bound what an agent may generate. Multi-catalog parsing and stricter binding are foundations for controlled hosts.
A closer look
Core adds CatalogApi, recursion and path checks, and local execution for functionCall/call actions. Agent SDK parsers now accept catalog sequences and validate each surface or component against its declared catalog.
Who this is for
A2UI implementers and Python agent or renderer developers
