A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Every brand has a voice. This skill gives it eyes.
Voice-profile.md defines how the brand sounds. Visual Brand Style defines how it looks — the lighting, the composition, the mood that makes someone see an image and know it's yours before reading a word.
brand/creative-kit.md if it exists. Check for a ## Visual Brand Style section.creative-kit.md doesn't exist: create it first with mktg init, then proceed.brand/voice-profile.md if it exists — personality informs visual tone (e.g., playful voice = warm/bright visuals, authoritative = clean/precise).brand/positioning.md if it exists — angles inform visual metaphors (e.g., "the simple alternative" = minimalist aesthetic).Use AskUserQuestion:
"How do you want to define your visual brand style?"
The user provides a URL or set of URLs (website, landing page, social profiles).
Fallback: If WebFetch is unavailable, switch to Build mode and tell the user why.
Interview the user. Ask one question at a time via AskUserQuestion.
Question 1: Aesthetic anchor "Pick the closest match to how your brand should look visually:"
Question 2: Lighting and mood "What lighting feels right for your brand's images?"
Question 3: Composition "How should images be composed?"
Question 4: What to avoid "What should your images NEVER look like?" (Free text — the user's avoidances are often more revealing than their preferences)
Question 5: Reference "Name a brand, website, or aesthetic that captures what you're going for — even if it's in a completely different industry."
Optional Question 6: Existing assets "Do you have any images that already feel on-brand? Describe them or share URLs."
Synthesize answers into the Visual Brand Style format.
The user provides mood boards, image URLs, or descriptions of their ideal visual style.
Write the ## Visual Brand Style section into brand/creative-kit.md. Preserve all existing sections (Brand Colors, Typography, Visual Style). Only add/update the Visual Brand Style section.
## Visual Brand Style
- **Primary Aesthetic:** [derived aesthetic, e.g., "warm tech minimalism with editorial photography"]
- **Lighting:** [specific lighting direction, e.g., "soft diffused with rim lighting accents, warm color temperature"]
- **Backgrounds:** [background treatment, e.g., "dark slate (#0F172A) with warm accent gradients"]
- **Composition:** [layout approach, e.g., "single focal point, generous negative space for text overlay"]
- **Mood:** [emotional tone, e.g., "calm empowerment — powerful but approachable, like a quiet expert"]
- **Avoid:** [explicit exclusions, e.g., "generic stock photos, cold blue tech grids, floating 3D cubes, busy compositions"]
- **Reference Prompts:**
1. [A proven prompt that captures the brand look — ready to paste into image gen]
2. [A second prompt showing a different use case in the same style]
3. [Optional third prompt for edge cases]Reference Prompts are critical. These are the style anchors that /image-gen uses when generating on-brand images. They should be complete, narrative prompts (not keywords) that produce images distinctly this brand.
When ## Visual Brand Style already exists:
| Level | Context | Output quality |
|---|---|---|
| L0 | No brand files | Generic but functional — asks user directly, writes style from scratch |
| L1 | voice-profile.md exists | Personality-aligned — playful voice gets warm visuals |
| L2 | + creative-kit.md colors/typography | Color-constrained — prompts incorporate brand palette |
| L3 | + positioning.md | Full alignment — visual metaphors match positioning angles |
| Anti-pattern | Why it fails | Instead |
|---|---|---|
| Locking into one rigid style | Brands need versatility — a blog header and an error page shouldn't look identical | Define the core aesthetic but include "also works for: [alternative moods]" in reference prompts |
| Ignoring existing creative-kit.md sections | Overwriting colors/typography the user already defined breaks trust and loses work | Read and preserve existing sections, only add/update Visual Brand Style |
| Generic descriptions like "modern and clean" | Every brand says this — it gives image-gen nothing to work with | Be specific: "warm rim lighting on dark backgrounds, single subject, f/2.0 bokeh" |
| Skipping the Avoid list | What to avoid is often more distinctive than what to include — it prevents the generic | Always ask what the brand should NEVER look like |
| Writing keyword prompts instead of narrative | Image gen models produce better results from flowing descriptions than comma-separated terms | Reference prompts should read like a scene description, not a tag list |
