+- Agent Prompt: Session title and branch generation - added explicit instruction to use sentence case for titles (capitalize only the first word and proper nouns), not Title Case
+- Tool Description: Bash (Git commit and PR creation instructions) - simplified git commit --amend guidance by removing complex conditional rules (5 conditions about when amending is allowed); replaced with simpler CRITICAL directive to always create new commits and never use --amend unless user explicitly requests it; removed reference to "amend rules above" in pre-commit hook failure step
