CLAUDE SKILLS ARE AWESOME, MAYBE A BIGGER DEAL THAN MCP

Summary from the TLDR newsletter

Claude Skills are folders that include instructions, scripts, and resources that Claude can load when needed to improve performance on specific tasks. Each skill has a Markdown file telling the model how to do something, optionally accompanied by extra documents and pre-written scripts the model can run to help it accomplish tasks. At the start of a session, Claude scans all available skill files and reads a short explanation for each one, which is very token-efficient. Skills are easy to share - the upcoming Cambrian explosion in Skills will make the MCP rush look pedestrian by comparison.
