Agent Skills Management

Use the pinned known-good CLI version unless the user explicitly asks to check latest behavior:

npx -y skills@1.5.3 <command>

Defaults

• Prefer global installs for personal tooling: -g.
• Install to all supported agents by default: --agent '*'.
• Use --all only when installing all skills from a source to all agents.
• Quote '*' so the shell does not expand it.
• Use -y only after the target source, skills, scope, and agents are known.
• Treat update, upgrade, and check as write-capable. In skills@1.5.3, check runs the same update flow and can install updates.
