Cheapest next steps

1. llms.txt: one Markdown index file; the most widely read agent-facing file
   Generate starter /llms.txt for gcore.com

   # Gcore
   
   > Gcore and what it offers to agents
   
   Short notes an agent should know before using the site: what it is for, who runs it, how to cite it.
   
   ## Docs
   - [Getting started](https://gcore.com/docs/getting-started): the first page to read
   - [API reference](https://gcore.com/openapi.json): OpenAPI description
   
   ## Optional
   - [Changelog](https://gcore.com/changelog): what changed, newest first
   

2. Agentic Resource Discovery: a catalog at /.well-known/ard.json lets agents discover your APIs, MCP servers and data in one fetch (emerging spec — publish only if you run the underlying endpoints; generate via MCP template({"id": "ard", "domain": "gcore.com"}))
3. AGENTS.md: instructions for coding agents working on or with the site
   Generate starter /AGENTS.md for gcore.com

Agent pre-flight & practical readiness

Preferred mode: mcp (fallback openapi). Call the MCP endpoint at https://gcore.com/mcp first. Do not scrape the HTML when a tool can answer.

Fetch: POST https://gcore.com/mcp POST a JSON-RPC tools/list, or server/discover on the 2026-07-28 revision, before reading HTML.

Practical readability: exa_parsable yes, markdown negotiation yes, render markdown_native, HTML quality high, first content at byte 0.

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

Readiness subscores: reach 20/20, readability 28/30, capabilities 22/35, conformance 15/15, total 85/100, grade A+.

How the grade is made

+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. Errors are specification violations; warnings are best-practice gaps. Only public paths are fetched, without credentials, so standards that need a login (skipped in the probe) are not counted either way. The same report is the validate_manifest tool on the MCP server.
