# Skills Index — Browsing and Managing CC Commander Skills
> How CC Commander's 450+ skills are organized into tiers and domains, how to find the right skill, and how to install or remove skills for your workflow.
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.
```bash theme={null}
ccc --skills tier essential
```
Includes everything in Essential plus high-value skills for active builders: `senior-backend`, `coding-standards`, `github`, `postgres-patterns`, `redis-patterns`, `setup-deploy`, `benchmark`, `gstack`, `confidence-check`, `brainstorming`, `context-mode`, and more.
Recommended if you work across multiple domains and want deep coverage without installing everything.
```bash theme={null}
ccc --skills tier recommended
```
Only the 11 CCC mega-skill domain routers. Useful if you want to install domain intelligence without the full workflow skill set.
```bash theme={null}
ccc --skills tier domain
```
Every skill on disk. Legacy behavior. Not recommended for most users — loads significant context overhead.
```bash theme={null}
ccc --skills tier full
```
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.

## Browsing Skills
Run `ccc --skills` to open the interactive skill manager. You can list installed skills, install skills by name, remove skills, and change tiers.
Type `/ccc:skills` in any Claude Code session. CC Commander reads your current project stack and shows context-aware recommendations ranked by relevance.
The skill index at `~/.claude/SKILLS-INDEX.md` is a searchable text file:
```bash theme={null}
grep -i "auth" ~/.claude/SKILLS-INDEX.md
```

## 11 CCC Domain Routers
Each domain router is a single skill that dispatches to the right specialist sub-skill based on your task. Load one domain and you get an entire specialty.
15 skills — TDD workflow, Playwright E2E, verification loops, visual regression, load testing, coverage reports, test fixtures, mock strategies, and accessibility testing.
20 skills — GitHub Actions, Docker, AWS deploy, Terraform, zero-downtime deploys, monitoring, Kubernetes, Nginx, SSL certs, environment management, health checks, and rollback strategies.
20 skills — auth systems, Stripe billing, API design, database schema, multi-tenancy, onboarding flows, admin dashboards, role-based access, webhooks, rate limiting, usage tracking, and feature flags.
35+ skills — landing pages, UI audit, animation, responsive layout, color systems, typography, wireframes, component libraries, accessibility, dark mode, micro-interactions, and design tokens.
9 skills — OWASP top 10, pen testing, secrets scanning, dependency audits, container security, threat modeling, CSP headers, rate limiting, and auth hardening.
46 skills — CRO, email campaigns, ad copy, social media, SEO content, blog posts, landing page copy, A/B testing, funnel optimization, lead magnets, newsletter, brand voice, and press releases.
19 skills — meta tags, JSON-LD schema, sitemap, robots.txt, Core Web Vitals, internal linking, keyword research, content optimization, image SEO, page speed, and structured data.
8 skills — competitive analysis, market research, user research, technology evaluation, trend analysis, SWOT, stakeholder interviews, and data synthesis.
8 skills — SQL optimization, ETL pipelines, data warehousing, analytics setup, data visualization, machine learning, reporting, data quality, and vector search.
7 skills — React Native, Expo, mobile UI patterns, push notifications, deep linking, app store optimization, offline-first, and gesture handling.
3 skills — `/xray` project audit (health score 0–100, maturity 1–5), `/makeover` agent swarm execution, and before/after report card.

## Key Skills by Category
### Code Quality
| Skill | What It Does | Tier |
| ---------------------- | --------------------------------------------------------------- | ----------- |
| `senior-backend` | Senior-level backend code patterns and architecture guidance | recommended |
| `coding-standards` | Enforce consistent code style and standards across your project | recommended |
| `systematic-debugging` | 4-phase root cause analysis before fixing | essential |
| `architecture-auditor` | Review and score architectural decisions | full |
| `review` | Structured multi-pass code review | essential |
| `codex` | Adversarial second-opinion code review | recommended |
### Testing
| Skill | What It Does | Tier |
| -------------- | ------------------------------------------------------------------------------------------- | ----------- |
| `ccc-testing` | Domain router — 15 testing sub-skills | essential |
| `benchmark` | Performance regression detection — baselines for page load, Core Web Vitals, resource sizes | recommended |
| `tdd-workflow` | Test-driven development: red/green/refactor cycle | full |
### DevOps and Deployment
| Skill | What It Does | Tier |
| -------------- | --------------------------------------------------------- | ----------- |
| `ccc-devops` | Domain router — 20 DevOps sub-skills | essential |
| `github` | GitHub Actions workflows, PR automation, issue management | recommended |
| `setup-deploy` | Zero-to-production deployment setup | recommended |
### SaaS Building
| Skill | What It Does | Tier |
| ------------------- | -------------------------------------------------------- | ----------- |
| `ccc-saas` | Domain router — 20 SaaS sub-skills | essential |
| `postgres-patterns` | PostgreSQL schema design, query optimization, migrations | recommended |
| `redis-patterns` | Redis caching, queuing, and pub/sub patterns | recommended |
### Security
| Skill | What It Does | Tier |
| -------------- | ------------------------------------- | --------- |
| `ccc-security` | Domain router — 9 security sub-skills | essential |
### Token Optimization
| Skill | What It Does | Tier |
| ------------------ | ------------------------------------------------------------------------------------------ | ----------- |
| `caveman` | Strips markdown, emojis, and prose — \~75% output token savings during iteration | essential |
| `session-compress` | Compress session context at logical breakpoints | essential |
| `context-budget` | Visual context window budget analyzer with zone indicators and bloat sources | essential |
