Class ClassPathSkillLoader

java.lang.Object
dev.langchain4j.skills.ClassPathSkillLoader
@Experimental public class ClassPathSkillLoader extends Object
Loads skills from the classpath (including cases when they are packaged inside a JAR file that is on the classpath).

Each skill must reside in its own directory containing a SKILL.md file. The file must have a YAML front matter block that declares the skill's name and description. The body of the file (below the front matter) becomes the skill's content.

Any additional files in the skill directory are loaded as SkillResources, except SKILL.md itself and any files under a scripts/ subdirectory. Empty files are silently skipped.
