Claude Code v2.1.222 4 Aug 2026

Thread rendering keeps summoning comments and marks new truncation kinds

You'll notice

Useful3 Signal0

Artifacts

Comments that triggered a turn are always kept in view instead of being trimmed away.

What

The thread renderer was replaced so the comments that actually caused this turn are never dropped to fit the budget.

Details

always keeps the newest comment plus every comment that summoned this turn, budgeting characters across them
new markers [summoning comment truncated] alongside [newest comment truncated] and [N comment(s) elided]
summoning_truncated added to the compose_thread_elided telemetry

Evidence

[summoning comment truncated]

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
