CC Commander ships with 450+ skills, but it does not load all of them into every session. Instead, skills are organized into tiers — small sets that keep your context window clean — and 11 domain routers that give you an entire specialty with a single load. This page explains how skills are structured, how to find what you need, and how to manage what is installed.

​
Skill Tiers

Skills are grouped into four tiers. The tier controls which skills are installed during setup and how many tokens they consume per session.
The default tier. Installs all 11 CCC domain routers plus the core workflow skills: spec-interviewer, systematic-debugging, investigate, review, ship, session-startup, writing-plans, executing-plans, caveman, context-budget, and more.Covers 90% of daily use cases. Saves approximately 10,000 tokens per session compared to loading everything.
You can load any skill on demand mid-session without installing it: say "use the skill-name skill" or "follow the skill-name skill" and Claude Code will load it from disk.
