openclaw skills install paperzilla fails because skills does not support subcommands yet, use clawhub install paperzilla.
Once installed, AI agents (Claude Code, Cursor, Windsurf, and others that support the AgentSkills standard) can list projects, browse feeds, search full feeds, and filter papers using pz commands.
You still need the pz CLI installed and authenticated — the skill teaches the agent how to use it.
To update the skill later, use openclaw skills update paperzilla or clawhub update paperzilla.
