    • listResources

      public io.reactivex.rxjava3.core.Single<com.google.common.collect.ImmutableList<String>> listResources(String skillName, String resourceDirectory)
      Description copied from interface: SkillSource
      Lists all resource files for a specific skill within a given directory.

      If the skill or the resource directory does not exist, the returned Single will terminate with a SkillSourceException.

      Specified by:
      listResources in interface SkillSource
      Parameters:
      skillName - the name of the skill
      resourceDirectory - the relative directory within the skill to list (e.g., "assets", "scripts")
      Returns:

      If the skill is not found or its frontmatter is malformed, the returned Single will terminate with a SkillSourceException or parsing error.

      Specified by:
      loadFrontmatter in interface SkillSource
      Parameters:
      skillName - the name of the skill
