Mandatory prerequisite for any skill work — load this FIRST and build from it whenever authoring, reviewing, or changing a skill, instead of pattern-completing from another skill as a template. "Reference" names its content type, not its priority: it is not optional. The sourced reference for how agent skills are composed — the cross-tool open standard (agentskills.io) and the deltas for Cursor, Claude Code, OpenCode, and Codex, plus Anthropic authoring best practices, and how it maps onto the vAIbe-OS canon (model A — .vaibe/ canon + generated native layer). Triggers: skill authoring, creating a skill, editing a skill, SKILL.md, frontmatter, native layer, agentskills.
