Quick Examples

AI/ML Engineering

/plugin install yzmir-deep-rl
/deep-rl  # Use slash command to load router skill

Claude will guide you to the right specialized skill:

I'm using yzmir/deep-rl/policy-gradient-methods to implement PPO for continuous character control

Web Backend Development

/plugin install axiom-web-backend
/web-backend  # Use slash command to load router

I'm using axiom/web-backend/fastapi-development to build production-ready async APIs with dependency injection

Game Development

/plugin install bravos-systems-as-experience
/systems-as-experience  # Use slash command to load router

I'm using bravos/systems-as-experience/emergent-gameplay-design to create systemic interactions in my RPG

Security Architecture

/plugin install ordis-security-architect
/security-architect  # Use slash command to load router

I'm using ordis/security-architect/threat-modeling to analyze this authentication system with STRIDE

UX Design

/plugin install lyra-ux-designer
/ux-designer  # Use slash command to load router

I'm using lyra/ux-designer/accessibility-and-inclusive-design to ensure WCAG 2.1 AA compliance

Architecture Analysis

/plugin install axiom-system-archaeologist
/system-archaeologist  # Use slash command to load router

Then Claude routes you to specialized analysis skills for C4 diagrams, subsystem catalogs, etc.

Using Router Skills: Slash Commands vs Direct Invocation

Slash Commands (Recommended)

All router skills (using-X skills) are available as slash commands to avoid skill context limits:

/ai-engineering          # Route to AI/ML specialized packs
/deep-rl                # Route to RL algorithm skills
/system-archaeologist   # Route to architecture analysis
/python-engineering     # Route to Python skills
/web-backend           # Route to web backend skills
/ux-designer           # Route to UX design skills
# ... and 12 more

Why slash commands? Router skills are comprehensive guides that exceeded the context budget for automatic skill discovery. Slash commands provide explicit, user-controlled invocation without context limits.

See `.claude/SLASH_COMMANDS.md` for the complete list of all router commands.

Direct Skill Invocation

If you have only a few plugins installed, direct skill invocation still works:

I'm using yzmir/deep-rl/policy-gradient-methods to implement PPO

Caveat: With many plugins installed (5+), you may hit skill discovery context limits. In this case, use slash commands for routers and direct invocation for specialized skills.

Best Practice:

• •Use slash commands for router skills (/ai-engineering, /deep-rl, etc.)
• •Use direct invocation for specialized skills after the router guides you
