Its helper
1 agent works by this book- stryx:prompt-engineerWhen a prompt for Claude needs writing or tightening: a skill, an agent, a CLAUDE.md.
Works with
the skills it names most- stryx:skill-forge→When creating or changing a skill, agent, slash command or hook, or a skill did not fire.
- stryx:ai-power→When you are not sure which skill fits, or you say "load aipower": it is the map of all skills.
- stryx:learn→You say "remember this" or wrap up a session: the lessons are saved for next time.
- stryx:config→When Claude Code's own setup needs checking or tidying: CLAUDE.md, settings, permissions, memory.
- stryx:debug→Something is broken: a bug, an error, a crash, a failing test or wrong data.
- stryx:design→When making anything you see: a screen, website, dashboard, logo, icon set, slides or charts.
Claude loads it by itself when the moment comes; by hand, type the line at the top. It comes with the whole set: Installs all 94 skills, 32 agents and the brain program as one set. The skill’s own text is private source and is not shown here.
