*3. Different philosophy*
- *agentskills.io* = Instructions for agents to read and interpret
- *Enact* = Executable package manifest with Docker images, typed I/O schemas, and containerized execution
*Bottom line:* Enact borrows the SKILL.md filename but extends it into something fundamentally different — a package manager format rather than an agent instruction format. It's not spec-compliant; it's a conceptual fork.
