Works with
the skills it names most- stryx:debug→Something is broken: a bug, an error, a crash, a failing test or wrong data.
- stryx:error-handling→When building code that must fail well: retries, timeouts, fallbacks and messages people can read.
- stryx:test→When tests must be written or fixed, or you want the test written first (TDD).
- stryx:verify→When Claude is about to say done, fixed or ready to commit: fresh proof comes first.
- stryx:ai-power→When you are not sure which skill fits, or you say "load aipower": it is the map of all skills.
- stryx:architect→When the hard part is structure: how the parts of a system fit, and the trade-offs between designs.
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.
