In plain words
What is it for?
Use it before creating or generating paid-advertising materials from a website. It can analyze the full site or just the homepage with the quick option.
Why use it?
It gives advertising work a shared description of the brand, so you do not have to describe the company’s style manually each time.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

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.

Security

Grade A, and why

ads-dna 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 8d ago.

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.

Use the **browser tool** (agent_browser or curl) to retrieve each page. For each URL, extract:

The opening of the file, as written. The whole thing — 226 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ads DNA: Brand DNA Extractor

Extracts brand identity from a website and saves it as brand-profile.json for use by /ads create, /ads generate, and /ads photoshoot.

Quick Reference

Command What it does
/ads dna <url> Full brand extraction → brand-profile.json
/ads dna https://acme.com --quick Fast extraction (homepage only)

Process

Step 1: Collect URL

If the user hasn't provided a URL, ask:

"What website URL should I analyze for brand DNA? (e.g. https://yoursite.com)"

Step 2: Fetch Pages

Use the browser tool (agent_browser or curl) to retrieve each page. For each URL, extract:

"Return all visible text content, the full contents of any <style> blocks, inline style= attributes, <meta> tags, Google Fonts @import URLs, and any og:image values found on this page."

Fetch in this order:

  1. Homepage (<url>)
  2. About page: try <url>/about, then <url>/about-us, then <url>/our-story
  3. Product/Services page: try <url>/product, then <url>/products, then <url>/services

If --quick flag was provided: fetch the homepage only; skip steps 2 and 3.

If a secondary page returns a 404 or redirect error, continue with fewer pages and note: "Secondary pages unavailable; extraction based on homepage only. Confidence may be lower."

Step 2b: Capture Brand Screenshots

After fetching pages, capture 3 screenshots for comprehensive brand anchoring. These serve as visual style references during /ads generate; the same approach Pomelli uses to anchor ad images to the actual brand aesthetic.

Capture the following:

  1. Homepage hero section (above the fold) — use browser MCP tool to navigate and screenshot
  2. Product or services page — navigate to /products and screenshot
  3. About page (brand personality) — navigate to /about and screenshot

Save screenshots to ./brand-screenshots/{domain}_{page}.png. Use the agent_browser MCP or Playwright MCP for screenshots. If no browser MCP is available, skip screenshot capture and rely on text extraction.

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.
