+## Built-in Skills
+
+Four Skill groups ship in the box ([docs](https://penguin.ooo/docs/skills)); Agents can also write and optimize their own:
+
+| Group                | Skills                                                                            |
+| -------------------- | --------------------------------------------------------------------------------- |
+| Office Productivity  | `data-analysis`, `firecrawl`                                                      |
+| Software Development | `web-design`, `software-engineering`                                              |
+| AI App Development   | `penguin-sdk`, `penguin-cli`, `agenthub-models`                                   |
+| Agent Tuning         | `agent-creation`, `benchmark-design`, `agent-evaluation`, `agent-optimization`    |
