+### Gitea Secret Naming Rules
+
+Gitea has specific rules for secret names:
+- Must contain only alphanumeric characters ([a-z], [A-Z], [0-9]) or underscores (_)
+- Cannot start with `GITHUB_` or `GITEA_` prefix
+- Cannot start with a number
+- Not case-sensitive
+- Must be unique at the repository level
+
+**Therefore**: Use `GH_TOKEN` instead of `GITHUB_TOKEN` for the GitHub access token.
