| Claude Code mods | JavaScript/TypeScript event handlers run inside Claude Code and can add interactive panes. | Choose a mod for an interactive terminal pane or in-process event handling; review the source and permissions first. |
| skills | Skills package instructions in SKILL.md, optionally with supporting scripts and resources. They guide the agent rather than register a mod UI handler. | Choose a skill for a repeatable task with instructions and supporting resources. |
