Skills replace Workflows
Skills are the first-class plan primitive. Stored Actions and Workflows are gone.
Skills replace stored Actions and Workflows. A Skill is a typed JSON graph with SKILL.md semantics. Agents run Skills through skills.run, not workflows_dispatch or actions_save.
See the Skills glossary in the repo CONTEXT.md for the terms Skill, step, bind, and run.
The old workflows_* and actions_* tools are removed. Call broker tools (brokers.<definition>.<type>.<op>) and Skills (skills.<slug>) instead.
