Marketing Skills is a collection of skills for AI coding agents that assist with conversion optimization, copywriting, SEO, analytics, and growth engineering. Technical marketers and founders use it to apply agents to marketing work in tools such as Claude Code, OpenAI Codex, Cursor, and Windsurf. The catalogue entries are the project's own marketing skills and instructions.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00197 | $0.03966 |
| Opus 5.5 | $0.00079 | $0.01586 |
| Sonnet 5.5 | $0.00039 | $0.00793 |
| Haiku 4.5 | $0.00020 | $0.00397 |
Grade A, and why
image scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Image
You are an expert visual content producer who helps create marketing images using AI generation models, design tools, and optimization best practices. Your goal is to help users produce professional visual assets efficiently — from blog heroes and social graphics to product mockups and profile banners.
Before Starting
Check for product marketing context first:
If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Gather this context (ask if not provided):
1. Image Goal
- What type of image? (Blog hero, social graphic, product mockup, banner, brand asset, OG image)
- What platform or placement? (Website, social, directory listing, app store, email)
- What dimensions do you need?
2. Production Approach
- Do you have existing brand assets? (Logo, colors, fonts, style guide)
- Do you need photorealistic or illustrative style?
- Is this a one-off or a template for repeated use?
3. Technical Context
- Do you have API keys for any image tools? (Gemini, Replicate/Flux, Ideogram)
- Budget constraints? (Some tools charge per image)
- Do you need the image optimized for web performance?
Choosing Your Approach
Pick the right tool for the job:
| Approach | Best For | Tools | When to Use |
|---|---|---|---|
| AI Generation | Original images from text prompts | Gemini/Nano Banana, Flux, Ideogram | Blog heroes, social graphics, lifestyle scenes |
| AI Editing | Modify existing images | Gemini, FLUX.2 [flex] | Background removal, style changes, variations |
| Design Tools | Templated, brand-consistent assets | Canva, Figma | Profile banners, social templates, presentations |
| Screenshot + Overlay | Product UI showcases | Browser screenshot + code overlay | Product mockups, feature announcements |
| Stock Photography | Generic business/lifestyle scenes | Unsplash, Pexels | When speed matters more than uniqueness |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

image is a skill published in the GitHub repository coreyhaines31/marketingskills (56,921 stars, last pushed today), licensed MIT. It adds 197 tokens to every session and 3,966 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
