## Standards observed

- AI Crawler User-Agent Tokens in robots.txt: https://cockroachlabs.com/robots.txt (https://agenticweb.wiki/protocols/ai-crawler-tokens-robots/)

## Cheapest next steps

1. llms.txt: one Markdown index file; the most widely read agent-facing file (https://agenticweb.wiki/protocols/llms-txt/)
2. Agentic Resource Discovery: a catalog at /.well-known/ard.json lets agents discover your APIs, MCP servers and data in one fetch (https://agenticweb.wiki/protocols/ard/)
3. AGENTS.md: instructions for coding agents working on or with the site (https://agenticweb.wiki/protocols/agents-md/)

## Agent pre-flight & practical readiness

Preferred mode: `exa_or_http_fetch`. No structured agent endpoint was found. The page has readable text, so fetch it directly or through a search index. cockroachlabs.com publishes no root agent discovery manifests, but docs.cockroachlabs.com serves /llms.txt (138 links). Probe docs.cockroachlabs.com or publish /.well-known/ard.json on cockroachlabs.com to link them.

Fetch: `GET https://cockroachlabs.com/` No structured agent endpoint was found. Fetch the public page or use a search index.

Subdomain discovery hint (`subdomain_stranded`): cockroachlabs.com publishes no root agent discovery manifests, but docs.cockroachlabs.com serves /llms.txt (138 links). Probe docs.cockroachlabs.com or publish /.well-known/ard.json on cockroachlabs.com to link them. (https://agenticweb.wiki/check/docs.cockroachlabs.com/)

Practical readability: exa_parsable yes, markdown negotiation no, render `ssr_rich`, HTML quality `high`, first content at byte 13824.

AI crawler posture: `open_to_all` · Assistant access: OpenAI `allowed`, Anthropic `allowed`, Google `partial`, Perplexity `partial`, Exa `allowed`.

Readiness subscores: reach 20/20, readability 20/30, capabilities 0/35, conformance 10/15, total 50/100, grade B.

## Rubric

+10 per lifecycle step with a standard observed, counting manifests that validate or that the probe rule for the standard recognises (a valid MCP server card counts for MCP; max 90); +3 per observed standard beyond the first two (max 15); conformance +15 (+10 with one manifest) minus 5 per agent-facing manifest with errors, never below 0 (security.txt is reported, not scored). Lifecycle grade: A+ >= 60, A >= 45, B >= 30, C >= 20, D >= 10. Strict 100-point composite (subscores.total_100 / subscores.grade_100): reach_and_policy (20) + readability (30) + capabilities (35) + conformance (15), where A+ >= 80, A >= 65, B >= 45, C >= 28, D >= 15.
