 `ponytail-lite`, `caveman`, `unlazy`, research, debugging, and review.
 The skill-forge workflow covers discovery, triggers, package anatomy,
 progressive instructions, structural validation, and behavioral iteration.
+The hands-on lab provides a tiny starter project and copy-ready baseline and
+skill-enabled prompts for a short side-by-side exercise.
+An interactive model gearbox separates capability tier from reasoning effort
+across OpenAI, Claude, and Gemini, and every featured skill links to a pinned
+source with an approval-first installation prompt.
