About the project

design-extract is a command-line tool that examines live websites with a headless browser and turns their visual and interaction rules into design-system files. It is used by developers and designers to extract tokens, component details, responsive behavior, accessibility findings, and platform-specific outputs, while the catalogue commands, skills, plugin, and rule expose that process to coding agents.

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

battle scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Pit two sites against each other and emit a single shareable HTML battle card.

npx designlang battle $ARGUMENTS

If $ARGUMENTS is empty or contains fewer than two URLs, ask the user for both sites.

Both sites are extracted in parallel (~30s total). Outputs land in ./design-extract-output/:

  • <a>-vs-<b>.battle.html — the shareable card
  • <a>-vs-<b>.battle.md — markdown summary
  • <a>-vs-<b>.battle.json — structured scores

After the run:

  1. Read the *.battle.md file
  2. Show the user the verdict line ("X wins" / "tie") and the per-dimension table
  3. Highlight the dimensions where the gap is widest
  4. Offer to open the HTML card

This is pure viral content — battles are designed to be tweeted. Pair with /grade <url> --badge so each side has a permanent badge to link back to.

Changes

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.
