The things people mix up

Four pairs that get confused constantly. Each one written from actually using both, not from the docs.

Plugins vs skills

One runs code inside your session. One is text the model reads.

Mods vs MCP servers

Both add capability. Only one runs in your terminal.

Being written

Mods vs slash commands

A command you type. A thing that runs when you did not type it.

Being written

Claude Code mods vs Codex mods

Same idea, different host, different failure modes.
