// IMPORTED CONTENT

addyosmani/agent-skills — MIT

github.com/addyosmani/agent-skills · by Addy Osmani · imported 2026-04-09 · ULK-048

Imported verbatim with attribution headers:

  • agents/_shared/checklists/accessibility-checklist.md — WCAG 2.1 AA quick reference
  • agents/_shared/checklists/performance-checklist.md — Core Web Vitals targets, frontend/backend checklists
  • agents/_shared/checklists/security-checklist.md — OWASP Top 10, auth, headers, CORS

Wired into 06-a11y-auditor, 07-perf-auditor, 45-sargeras, frontend-qa, and the test agents. We did not import the 20 skills, 3 personas, 7 slash commands, or the simplify-ignore hook — users can install the full plugin separately.

Streamline Icons — CC BY 4.0

streamlinehq.com/icons/pixel · by Streamline · imported 2026-04-11 · ULK-056

All agent icons on this site are drawn from the Streamline Pixel pack (662 pixel-art glyphs), consumed via Iconify through @iconify-json/streamline-pixel and rendered by astro-icon. The mapping from each ulk agent to its icon lives in site/src/lib/agent-icons.ts.

Streamline Pixel is released under Creative Commons Attribution 4.0 International (CC BY 4.0) . The license requires attribution on any page where the icons are displayed — which this card provides for the entire site.

internet-development/www-sacred — MIT

github.com/internet-development/www-sacred · the Sacred Computer design system

This site is a native Astro port of Sacred Computer, the terminal-aesthetic component library by Internet Development Studio Company. Every component under site/src/components/srcl/ mirrors a component from www-sacred, rewritten as a pure .astro component with the same visual grammar — 1ch grid, IBM Plex Mono, box-drawing characters, and the original colors.json palette (#e4f221 lime brand, monochrome terminal surfaces).

// PRINCIPLES

  1. No vendoring by default. We prefer referencing upstream projects via install-path flags rather than copying source code. Exception: small, tactical files (checklists, patterns, snippets) that evolve slowly and benefit from being inlined for zero-latency reference by agents.
  2. Preserve attribution. Every imported file carries an HTML comment header pointing to upstream source, license, author, import date, and ticket number.
  3. Credit upstream authors. This page is the central registry. Contributions upstream remain with their original authors.
  4. Licenses compatible with ulk (MIT). We only import from MIT, Apache-2.0, BSD, or similar permissive licenses.
REPORTING ATTRIBUTION ISSUES

If you are an upstream author and believe this page under-credits your work, or if you would prefer a specific import to be removed, please open an issue at github.com/izo/ulk/issues.
