What

Compaction is the step where Claude Code shortens a long conversation by summarizing earlier parts of it. After compaction, when a certain condition holds, an internal value called noChannelTools is now reset along with declaredTools, which was already being reset.

Why

The two values are now cleared together, so noChannelTools no longer carries over past a compaction in the cases where declaredTools is cleared.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe finding does not say what condition triggers the reset or what `noChannelTools` controls.
