Under the hood
Transcript ingest now separately tracks tool declarations that only announce a name versus full tool entries
What
When Claude Code reads in a transcript and processes declared MCP tools, it now keeps two separate records: nameOnlyAnnouncements, for declarations that only give a tool's name, and entries, for full tool declarations. Previously, only full entries were merged into the tracked state; name-only announcements weren't handled separately.
Why
This lets Claude Code distinguish a tool that's merely been announced by name from one that's been fully declared, which likely affects how it decides whether a tool is ready to use.
