Claude Code mods: setup and 10 customization examples

This tutorial explains how the speaker customizes Claude Code with mods, starting with a terminal pet, a color theme and a footer bar. He distinguishes a prompt, which asks for an immediate task, from a skill, which stores reusable instructions, and a mod, which adds code that changes behavior during a session.

The setup uses plugin installation through a terminal inside the Claude desktop app. The speaker explains user and project scopes, plus a shared project scope for teams. He compares mods with event hooks and says some can execute without spending AI credits because they do not need a language model to orchestrate them.

The practical examples focus on observing and organizing a coding assistant session. Repo Heatmap shows the distribution of repository files. Flight Recorder displays requests, model use and tool activity. Model Router assigns models to subagents; the demonstration sends two exploration tasks to Sonnet and checks their activity in Flight Recorder. Output Tray lists generated files, while Changes Receipt gives a shorter summary. Session Bookmarks stores notes and links back to conversation points.

Auto Handoff starts a fresh session at a configurable threshold, set to 85% in the example, and also supports a manual trigger. The tutorial ends with removing mods at their installation scope.
