Under the hood
New internal flag tracks whether a 'tool result screening OK' signal has been sent this session
What
Claude Code keeps some internal per-session bookkeeping about the current model setup. A new boolean field, toolResultScreeningOkEmitted, was added to this bookkeeping, along with a pair of functions to check its value and to set it to true, alongside existing tracking fields for tool-change headers and internal safeguards.
Why
This is internal bookkeeping with no described user-facing effect; the finding does not say what feature it supports.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say what feature or behavior this tracking flag controls or enables.
