+# AGENTS.md
+
+Guidance for AI agents working in this repository.
+
+## Commits
+
+Never add a `Co-Authored-By` trailer. Do not credit Claude, Opus, or any AI
+assistant as a co-author, in commit messages or anywhere else.
+
+Keep commit messages terse: one concise lowercase subject line, a short body only
+when the change needs it.
