+# AI Agent Instructions for gohugo
+
+## Tagging AI-Involved Content
+
+When creating or editing Hugo content files under `site/content/`, apply the following tags in the frontmatter:
+
+- **`AI-gen`** — Add this tag when the article was mostly written by AI (i.e., the majority of the text was generated by an AI agent).
+- **`AI-reviewed`** — Add this tag when the article was reviewed, edited, or refined by AI but the original content was primarily human-written.
+
+These tags go in the `tags` array in the TOML frontmatter. For example:
+
+```toml
+tags = ['some-topic', 'AI-gen']
+```
+
+If both apply, include both tags.
