A procedure for checking whether a website is easy for AI agents to discover and use. It checks files and pages such as llms.txt, robots.txt, and Markdown versions of content.

In plain words
What is it for?
Use it to review a website's agent-readiness and identify changes such as adding an llms.txt guide, adjusting crawler rules, or providing Markdown content.

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

agent-readiness-audit scanned grade A with 1 finding 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 6d 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.

Agent readiness audit

Audit how well a website serves AI agents by probing its standard discovery surface. Everything here is plain HTTP GETs against well-known paths; no tooling beyond fetch/curl is needed. Run the probes, then report what exists, what is missing, and the fix for each gap.

The probes, in order of importance

For the target domain https://example.com, check each of these and note status code, content type, and whether the content is real or a stub:

  1. /llms.txt: the site guide for agents. Good ones are a curated navigation index under ~30k characters with markdown links that resolve. A missing or bloated llms.txt is the single most common gap.
  2. /robots.txt: look for explicit AI-crawler sections (GPTBot, ClaudeBot, PerplexityBot, Google-Extended), a Content-Signal: line, and whether user-triggered agents (ChatGPT-User, Claude-User) are allowed. Open-by-default scores worse than a considered, tiered policy.
  3. Markdown availability: fetch a content page with Accept: text/markdown, try the page URL plus index.md, and look for rel="alternate" type="text/markdown" in the HTML head. Agents parse markdown far more reliably than a JS-heavy DOM.
  4. /openapi.json (also /api, /docs, /developers): a real, reachable API with a spec is the difference between "agents can read about you" and "agents can use you". Check error responses are JSON, not HTML.
  5. MCP surface: /.well-known/mcp.json, /.well-known/mcp/server-card.json, and a POST of a JSON-RPC initialize to any advertised endpoint. Also search the official registry: https://registry.modelcontextprotocol.io/v0/servers?search=<domain>.
  6. Identity and trust: homepage JSON-LD (Organization with sameAs and contactPoint, plus extended types like Service), /.well-known/ard.json, /.well-known/agent-card.json (A2A), /auth.md.
  7. Sitemap hygiene: /sitemap.xml exists, entries carry lastmod, and the newest entry is recent.

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.
