How this skill gets triggered: by you, by Claude, or both.
- Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

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 locations** — skills/commands/agents not inside `.claude-plugin/` 10. **MCP tool references** — tools in `allowed-tools` are valid `mcp__plugin_ruflo-core_ruflo__*` identifiers
Steps
1. Read the plugin's `plugin.json` and assert no `skills` / `commands` / `agents` arrays present 2. Glob `skills/*/SKILL.md`, `commands/*.md`, `agents/*.md` and validate each frontmatter 3. For each SKILL.md, verify frontmatter has required fields and `allowed-tools` has no wildcards 4. For each agent .md, verify frontmatter has required fields 5. Report pass/fail for each check with actionable fix suggestions

An agent meta-harness for Claude Code and Codex. Agent = Model + Harness. The model writes; the harness gives it tools, memory, loops, sandboxes, and controls so it can actually work.
