The skill was corrected mid-investigation to present theme.colors[key] as the default, simpler path and reserve the isColorAlias/getColorValue chain for consumers that need a literal (non-var()) value -- e.g. canvas, WebGL, or contrast math -- rather than presenting the longer chain as universally required.",
+    "with_skill is dramatically cheaper and faster here (40.1s/25,760 tokens vs 322.8s/37,679 tokens) -- reading the skill first let the agent go straight to a correct, cited-precedent answer instead of spending several minutes discovering the right pattern from scratch.",
