Tip: Bundled Skill Aliases Like `/checkup` and `/review` Were Broken in `-p` Mode When Shadowed by a Local Skill
Claude Code 2.1.233 fixed bundled skill aliases reporting 'Unknown command' in `-p` mode, or when plugins/MCP were loaded, if a user or project skill shadowed the bundled skill of the same name. If you have automation that calls bundled slash commands headlessly and quietly stopped working, a name collision in `.claude/skills` is the likely cause rather than the command itself. The same release added `claude plugin validate` checking of a bare `.claude/skills` directory, reporting SKILL.md files whose frontmatter fails to parse — worth running once over any skills repo.
