What people warn about
Each mark is one comment
Unreliable, nondeterministic triggering or execution
“It's not deterministic but it definitely runs each skill and it's raised a bunch of issues”
Comment from 15 Mar 2026 in “Claude Doubles Usage Limits During Off-Peak Hours (March 13–27, 2026)” “Skills don't really accomplish that well and are more unreliable when your target audience is a B2B customer”
