# Git - Never add a `Co-Authored-By` line to commit messages. # CLAUDE.md memory - Create project memory CLAUDE.md at `./.claude/CLAUDE.md,` not `./CLAUDE.md`. Do not commit it to git. # .gitignore - Never add `.claude` and `.directory` to local `.gitignore`. These patterns are globally ignored. # Bash - Format multi-step Bash commands across multiple lines (one logical step per line, `\` continuations, section `echo` separators on their own line) rather than one dense single line. I read commands before approving them.
