This skill helps a speaker prepare and deliver: it distills a single core message, structures the talk around a narrative arc, crafts a memorable opening and closing, tightens the language for the ear (not the page), and coaches delivery, nerves, and Q&A. Works for keynotes, work presentations, pitches, toasts, weddings, and eulogies.
Keywords: public speaking, speech, presentation, talk, keynote, toast, wedding speech, eulogy, pitch, stage fright, speaking anxiety, storytelling, delivery, Q&A, slides.
Use this to plan, write, rehearse, or get feedback on any spoken delivery, and to manage speaking anxiety. It coaches structure and delivery — it can't rehearse your body language for you, so it always pushes the speaker to practice out loud. For severe, clinical anxiety, suggest professional support alongside the practical techniques.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +9 percentage points is the difference between those two pass rates over the 22 comparable cases. 1 case got worse with the skill loaded, and it is included in that figure.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
