Managing, Updating, and Organizing Agent Skills
Nowadays, using skill files (SKILL.md) is a common way to provide context and knowledge (or new capabilities and expertise, as the official skills specification website describes) to an LLM or agent. From an infrastructure point of view, a skill is a folder containing a SKILL.md file and all the necessary files for it to work: scripts, references, etc. This folder must be in .agents/skills (or .claude/skills, or whatever name your agent tool uses).
