reference

The invocation arguments name one reference file and, optionally, one entry point within it.

These references load by part: alpha. For one of these, a second argument names a part.

These entry points read their own file: gamma check-it. A request on one of their references, with or without a second argument, reads the entry-point rules, ${CLAUDE_PLUGIN_ROOT}/skills/reference/entry-files.md, with or before its other reads, unless their text is in this conversation word for word, and follows them.
