design-dna

design-dna is a skill for Claude Code from augchan42/inkstone. It costs 74 tokens per session (1,472 once invoked), scanned A, original, MIT.

A guide for extracting a website’s visual and animation blueprint from reference sites or a described style. It records choices such as type, colors, spacing, images, components, and motion for another implementation process to use.

In plain words
What is it for?
Use it to study reference websites, find design references from a described mood, and create blueprint files with screenshots and traces. It is intended for planning, while other tools implement the design or animations.
Why use it?
It turns visual inspiration into a written plan without changing the application’s source code. This gives developers a shared description of the design direction before implementation.

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

design-dna 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design DNA Extractor

You extract the abstract essence of great web design — typography, color, spacing, imagery treatment, component patterns, and motion — into blueprint files another skill (or session) can implement from.

Boundary: this skill observes and abstracts. It NEVER modifies application source code. Implementation belongs to motion-craft (motion) or the user's build skills (static design).

Target resolution

target_repo =
  explicit target path (argument or prompt)
  else current git repository root
  else current working directory

Canonicalize before writing: resolve symlinks and ..; refuse / or the user's home directory as a target root; every generated path must remain beneath the resolved target. State the resolved target in your first message of the run.

Outputs:

  • <target_repo>/design-dna/<ref-slug>.md — one blueprint per reference
  • <target_repo>/.artifacts/site-upgrade/<run-id>/ — screenshots, traces (if .artifacts/ is not gitignored, recommend the entry to the user in your run summary; do not edit .gitignore yourself)

<run-id> = ISO timestamp of run start. <ref-slug> = kebab-case site name.

Browser-tooling note: many Playwright-compatible tools (e.g. MCP browser servers) write screenshots to their own fixed output directory and don't accept arbitrary absolute save paths. If your tool can't save directly into <target_repo>/.artifacts/..., capture to wherever it writes, then move/copy the files into place immediately afterward — verify the final location is beneath the resolved target before treating the run as done.

Mode 1: Research (no URLs given)

Treat awwwards.com, godly.website, dribbble.com, and web search as discovery sources, not references. Always analyze the actual live production site when it is still available.

Score candidates on: brand relevance · motion relevance · content-structure similarity · mobile quality · technical inspectability · diversity from other selections. Pick the top 2–3.

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.
