Bug Description Claude Code ignored my explicit instruction to avoid parallel tool calls.

Expected:

  • Read all feedback/memory files first
  • Process files one at a time
  • No parallel Read/Write/Edit calls across different files

Actual:

  • It admitted it only opened 5 of 19 memory files
  • It skipped an important memory file
  • It performed multiple parallel Write/tool calls despite being told not to
  • Screenshot attached

This caused incorrect workflow behavior and broke user instructions.

Version: 2.1.145
