What's this about?
Cola Skill is a community-curated directory of Agent Skills — packaged instruction sets that extend coding agents — with daily additions.
What exactly is an Agent Skill?
A folder of instructions and scripts an agent loads to gain a workflow it didn't have — deploy steps, a review checklist, an integration. Installable know-how, to a first approximation.
Why is this worth noting?
Skills are becoming an ecosystem with marketplaces — and therefore a supply chain. Today's hook-attack paper is precisely about trusting third-party agent extensions; directories like this are where that trust question becomes practical.
