Skill
TL;DR
Internal procedural knowledge that tells Claude how to perform a specific task.
Definition
Internal procedural knowledge that tells Claude how to perform a specific task. Skills contain step-by-step instructions, examples of good and bad output, edge cases, and expected result formats — all written in plain Markdown, not code. Skills handle the "how"; Connectors handle the "where from" and "where to."
Exam Context
The exam tests whether you can distinguish Skills from Connectors. Skills cannot make network calls or access external APIs. If the workflow needs live data from an external service, you need a Connector.
