Bug Description Tool use has degraded significantly in the move from 4.7 to 4.8. This Reddit post describes it perfectly: https://www.reddit.com/r/ClaudeCode/comments/1tskdus/psa_if_claude_has_been_acting_up_this_week_its_a/

I had one session that completely fell apart due to this and several where Claude decided to stop early and handoff. I've had to explicitly set rules like: "no parallel tool use", "no duplicate tool use - if something fails, don't just retry but figure out the cause of the failure", and "do not trust handoff data: re-verify from the source"

This is slowing me down and costing me tokens for an Ant bug. Please address this ASAP.
