- Add command execution rules to prompt (no env prefixes, no 2>&1) - Document pre-existing test failures so Claude doesn't waste turns - Add Bash(echo:*) and Bash(cat:*) to allowed_tools - Delete stale remote branches before creating new ones Addresses 24 permission denials in last run where Claude spent ~15 of 47 turns on blocked commands.
