What is an AI skill?
A skill is a packaged set of instructions, context, examples, standards, and supporting files that tells an AI agent how to do a specific job. If a prompt is one message you type, a skill is the reusable version your agent can keep using.
Think of it as a playbook for one repeatable CRE task.
Instead of asking an AI to “analyze this deal” and hoping it knows what good looks like, a skill tells it exactly how the task should be done, what to check, and what answer to return.
