2. Write plugins//.claude-plugin/plugin.json with name, version, description, author.
3. Drop skills under skills//SKILL.md (YAML frontmatter name + description, then body).
4. Add the plugin to plugins[] in .claude-plugin/marketplace.json with a relative ./plugins/ source.
5. Bump the plugin's version on every rel
