What
Two new message types for SDK consumers that provide a simplified view of Claude's output, stripping away thinking blocks and tool call details.
Details
streamlined_text-- preserves the text content from assistant messages but removes thinking and tool_use blocksstreamlined_tool_use_summary-- replaces verbose tool_use blocks with a human-readable summary string (e.g., "Read 2 files, wrote 1 file")- These message types are filtered out in the normal CLI transport layer and are intended for SDK streaming consumers

Evidence
New Zod schema types (search for "streamlined_text" and "streamlined_tool_use_summary")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
