## Skills

- ask-claude: Ask Claude for architecture, design, difficult reasoning or a second opinion. Use when the user requests Claude or an external specialist opinion would help an authorized task.
- ask-external-agent: Ask an external specialist for a useful second opinion, or fulfill a named request such as Gemini, Muse, Kimi, Qwen, DeepSeek, Claude or Grok through the common gateway.
- design-review: Review UI, visual design, screenshots or motion-design key frames against the user's goals or an accepted design. Typically uses Claude through the common external-agent gateway.
- x-research: Research recent X discussions, developer friction, implementation examples, complaints, accounts and threads through Grok's search capability.

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.
