Last week I wrote about AMA-teras, a desktop AI agent that writes its own tools behind verification gates. This week it learned to speak SKILL.md — the open standard for agent skills — in both directions. Here's what that means, why I think it matters more than any single feature, and the implementation details that surprised me.
The 30-second context
SKILL.md started as an internal format and became an open standard that 30+ coding agents now support — Claude Code, Codex CLI, Cursor, Gemini CLI, and the rest. A skill is just a folder:
my-skill/
SKILL.md # frontmatter (name, description) + instructions
