# Validate Plugin Validate that a plugin follows the correct Claude Code plugin format. ## When to use After creating or modifying a plugin, run validation to catch structural issues before publishing. ## Checks performed 1. **Directory structure** — `.claude-plugin/plugin.json` exists at plugin root 2. **plugin.json schema** — required fields present (name, description, version) 3. **Skills auto-discovery** — every `skills/<name>/SKILL.md` is a valid skill (Claude Code auto-discovers from directory; `plugin.json` MUST NOT list a `skills` array) 4. **Commands auto-discovery** — every `commands/<name>.md` is a valid command (auto-discovered; no `commands` array in `plugin.json`) 5. **Agents auto-discovery** — every `agents/<name>.md` is a valid agent (auto-discovered; no `agents` array in `plugin.json`) 6. **No legacy arrays in plugin.json** — presence of `skills`, `commands`, or `agents` arrays in `plugin.json` is a validation error (they cause Claude Code to reject the plugin) 7. **SKILL.md frontmatter** — each skill has `name`, `description`, and `allowed-tools` (no wildcards) 8. **Agent frontmatter** — each agent has `name`, `description`, and `model` 9. **No files in wrong loca

What does the validate-plugin skill do?
Validate a Claude Code plugin structure, frontmatter, and MCP tool references
How do I install it?
Run `npx skills add ruvnet/ruflo --skill validate-plugin --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ruvnet/ruflo, a repository with 67,015 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
