The top-level rivet-* skills and their embedded examples are generated by
rivet-dev/website
(.github/workflows/skills.yml). Only those directories are replaced on
each website publish.
skills/sandbox-agent is generated and published independently by
rivet-dev/agents
(.github/workflows/skill-generator.yml).
To change a generated skill, edit its source documentation in the owning repository. Other publishers' directories are preserved.
