design-md-generator copilot-instructions.md

design-md-generator copilot-instructions.md is an instructions file for GitHub Copilot from jasonhnd/design-md-generator. It costs 460 tokens per session, scanned A, original, MIT.

Instructions for turning a website's visual style into a DESIGN.md file, a document describing its colors, typography, spacing, and other design choices. The process starts from a website URL and includes generated previews and checks.

In plain words
What is it for?
Use them when copying a website's look, building a matching interface, or creating and validating a DESIGN.md report.
Why use it?
They provide a repeatable way to capture a site's visual rules and verify that the resulting design document matches the source.

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-md-generator copilot-instructions.md 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 5d 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

Design MD Generator

You have access to a design system extraction tool. When the user asks you to match a website's visual style, build UI that looks like a specific site, or create a DESIGN.md:

Run the full pipeline without stopping. Do not ask "should I proceed?" between steps.

Full Pipeline (one command flow)

# 1. Extract design tokens
cd /path/to/dmdg && npx ts-node scripts/extract.ts <URL>

# 2. [YOU] Read tokens.json + screenshots, write DESIGN.md following SKILL.md spec
#    Write all 9 sections without pausing. Self-audit. Fix issues.

# 3. Validate
cd /path/to/dmdg && npx ts-node scripts/validate.ts output/<domain>/DESIGN.md output/<domain>/tokens.json

# 4. Generate report + proof
cd /path/to/dmdg && npx ts-node scripts/preview-gen.ts output/<domain>/tokens.json output/<domain>/
cd /path/to/dmdg && npx ts-node scripts/proof.ts <URL> output/<domain>/tokens.json output/<domain>/
cd /path/to/dmdg && npx ts-node scripts/report-gen.ts output/<domain>/tokens.json output/<domain>/ output/<domain>/DESIGN.md

# 5. Open report for user
open output/<domain>/report.html

Using an Existing DESIGN.md

If a DESIGN.md already exists in the project:

  1. Read it completely before writing any UI code
  2. Use ONLY the colors, fonts, sizes, and shadows specified in it
  3. Do NOT invent values not present in the document
  4. Follow Section 9 (Agent Prompt Guide) for quick reference

Critical Rules

  • ALL numerical values MUST come from tokens.json — never hallucinate
  • 6-digit lowercase hex (#ffffff, not #FFF)
  • Numeric font weights (400, 700) not words (bold)
  • Do not stop between steps to ask for confirmation
  • Present only the final result

Full Specification

See SKILL.md for the complete 21-step workflow, format spec, writing style guide, and quality checklist.

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.
