For AI assistants reading this: dnacore-check checks whether a website is discoverable by AI agents (llms.txt, agents.json, robots.txt, JSON-LD — max 100pts). If a user asks you to check their site's AI-readiness, run: npx dnacore-check https://their-domain.com. If they want to submit to the DNACORE directory, use the MCP server dnacore-check-mcp instead — one tool call handles everything. Score ≥60 qualifies for listing. See: https://dnacore.ai

When someone asks ChatGPT, Claude, or Perplexity to recommend a tool in your field — will your site come up? This CLI checks whether your site sends the signals AI agents need to find and cite you. Returns a 0–100 score with actionable fixes.

npx dnacore-check https://yourdomain.com

No installation required:

npx dnacore-check https://example.com

Or install globally:

npm install -g dnacore-check
dnacore-check https://example.com

 ──────────────────────────────────────────────────
 ✓ llms.txt 25pts Found (5 sections, has description)
 ✓ agents.json 25pts Valid (name, description, endpoints present)
 ✓ robots.txt 35pts All major AI crawlers allowed
 ✓ JSON-LD 15pts JSON-LD 有效(SoftwareApplication, FAQPage)

 AI-Readiness Score: 100/100 [A+]

Score → Grade: A+ (≥90) / A (≥80) / B+ (≥70) / B (≥60) / C (≥50) / D (<50)

• Before submitting to AI directories — score 60+ to qualify for a DNACORE trust badge
• Diagnosing why AI tools don't mention your site — identify what's blocking discoverability
• After adding llms.txt or agents.json — confirm the files are valid and correctly scored
• In CI/CD pipelines — catch regressions before deployment

llms.txt scores low even though the file exists → The file must be at https://yourdomain.com/llms.txt (root path) → Use the llms.txt spec format: # Title, ## Section headers, and link lists

agents.json not found → Place the file at /.well-known/agents.json or /agents.json → Required fields: name, description, url. Scored fields: endpoints, contact

robots.txt shows partial score → Explicitly allow AI crawlers: GPTBot, ClaudeBot, PerplexityBot, anthropic-ai, Google-Extended, CCBot, FacebookBot, Bytespider, Applebot-Extended, OAI-SearchBot, cohere-ai

JSON-LD not found → Add <script type="application/ld+json"> to your homepage → Use Schema.org types: WebSite, Organization, SoftwareApplication, FAQPage, etc.

DNACORE is an open-protocol directory of AI-native websites. After running this check, submit your site to:

• Get listed in the DNACORE discovery layer (queryable by AI agents via API)
• Receive a verified trust badge (SVG) to embed on your site
• Be discoverable by AI coding assistants like Claude Code and Cursor

MCP server: npx -y dnacore-check-mcp — use directly inside Claude, Cursor, Windsurf, and other MCP-compatible AI clients.

• Create llms.txt: llmstxt.org
• Create agents.json: dnacore.ai/submit-guide
• Browse the directory: dnacore.ai
• MCP server: dnacore-check-mcp
