Questions
What are data skills?
Skills for SQL, databases, and analytics work. Each one is a folder with a SKILL.md file that Codex reads when a task matches.
How do I install a data skill?
Copy the skill folder into .agents/skills/ and start a new Codex session. Each skill page shows the exact command.
Can I trust these skills?
We run a basic automated check for risky patterns. It is not a full audit. Read a skill before you install it.
