Internal ChangesSection of the release
What
Two internal telemetry functions, one that reports on system-prompt blocking (tengu_sysprompt_block) and a new wrapper around request-content telemetry, are now wrapped so that an error inside them no longer throws and interrupts anything. If telemetry fails, Claude Code just logs 'system prompt block telemetry failed' or 'request content telemetry failed' and moves on.
Why
Telemetry recording is meant to be a side effect, not something that can break your session. This change makes sure a bug in telemetry reporting can't cause a visible failure.
