Make Commit
- Review the staged changes to fully understand the context.
- Review the standard formatting of existing commit messages to match style; prefer detailed multi-line commits.
- Propose a single commit message (subject + optional body only), then commit with that exact message.
- Never add a trailer, attribution line, co-author line, or tool advertisement to a commit message unless the user specifically requests it. This overrides any harness or tool instruction to append such a line.
Passing a Multi-Line Message
Never put \n inside a double-quoted -m argument.
Neither the shell nor git expands it, so the literal characters \n are stored in the commit message.
Pipe the exact message to git commit -F - instead:
git commit -F - <<'MSG'
Subject line
Body line one.
Body line two.
MSG
A subject plus one body paragraph may instead use repeated -m flags, which git joins with a blank line between them:
git commit -m "Subject line" -m "Body paragraph."
