└── README.md # Index and quick referenceBefore creating content, define 3-5 target personas in 07-brand-assets/persona-profiles.md:
markdown## Persona: [Name] ### Demographics - Role, Age, Team Size, Industry, Technical Level ### Goals - What they want to achieve ### Pain Points - Problems they face (be specific, not generic) ### Why Product Appeals - Feature-to-benefit mapping ### Key Message > "One sentence that resonates with this persona" ### Content They Respond To - Types of content that work
Lead with benefits, not features:
❌ "Includes auto-moderation feature"
✅ "Stop spam automatically — so you can focus on growing your community"Power words to use wisely: effortless, powerful, stunning, instant, automatic Words to avoid: revolutionary, game-changing, seamless, leverage, synergy, cutting-edge
Transform every feature into a benefit using:
markdown**What It Does:** [Feature description - plain language] **The Benefit:** [Outcome] — so you can [user benefit]. **Why It Matters:** - [Feature detail], which means [benefit] - [Feature detail], so you can [benefit]
Requirements:
Before creating visual content, ask: > "Do you have a local development setup where we can capture real screenshots? I'll need access to take authentic product images."
Structure for each video:
markdown## Video Details - Title, Duration, Purpose, Tone, Target ## Script ### INTRO (0:00 - 0:XX) **VISUAL:** [Description] **NARRATOR:** "[Script - conversational, not salesy]" **ON-SCREEN TEXT:** "[Text overlay]" ### [SECTION NAME] (X:XX - X:XX) ... ## Production Notes - Visual style - Music suggestions (upbeat but not overwhelming) - Screenshots needed (from local dev environment)
Twitter/X: (twitter-posts.md)
LinkedIn: (linkedin-posts.md)
Facebook: (facebook-posts.md)
Instagram: (instagram-captions.md)
Structure each email file with multiple templates:
One-Pager: Print-ready summary with:
Objection Handling: For each objection:
Always include accurate pricing from product page:
markdown| License | Price | Sites | |---------|-------|-------| | Single | $XX/yr | 1 site | | 5 License | $XX/yr | 5 sites | | Developer | $XX/yr | Unlimited |

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. 25 cases were attempted. The headline lift of +52 percentage points is the difference between those two pass rates over the 25 comparable cases.
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.
Other measured skills in the registry, with their headline benchmark lift.
