Skills

belt skill search "query"           # search the registry
belt skill use <namespace/name>     # fetch and print a skill (on-demand)
belt skill install <namespace/name> # install locally for your agent
belt skill list                     # list installed skills
belt skill get <namespace/name>     # view skill details
belt skill upload <path>            # publish a skill (dir with SKILL.md or single file)

Upload respects visibility — defaults to private. Change visibility on the platform. Same name = new version. Identical content is skipped (dedup).
