Tweet 1 (240 chars)
@Google invented the Google-Extended user-agent in 2023. The AI-training opt-out the rest of the web’s robots.txt now references.
We checked four Google surfaces.
None of them use it.
Score: 25/100. Level 1. Highest of four.

The variance: 25 / 15 / 5 / 5.
developers.google.com — 25/100, Level 1. The high water mark. cloud.google.com — 15/100, Level 1. google.com — 5/100, Level 0. blog.google — 5/100, Level 0.
developers.google.com/robots.txt is 3 lines long. That’s it.
Tweet 3 (258 chars)
The reason it’s the high water mark: the homepage hero references the CLI. gcloud, gemini-cli, firebase.
10 of 30 in agent-capabilities. Full marks in visibility-of-agent-integrations.
Cloud says SDK in body copy but doesn’t promote install above the fold.
Tweet 4 (258 chars)
Bot-access-control: 0/15 across all four surfaces.
No Google-Extended. No GPTBot. No ClaudeBot. No anthropic-ai. No Content-Signal.
Two and a half years after Google wrote the convention, none of these surfaces declare it.
The fix is one robots.txt block.
Tweet 5 (274 chars)
Discoverability: 0/25 across all four.
No /llms.txt anywhere. Not on developers, not on cloud, not on the blog, not on the marketing root.
Anthropic, Stripe, Vercel, Cloudflare ship it. Google’s developer subdomain — feeding the largest first-party docs corpus — does not.
Tweet 6 (268 chars)
Workspace MCP server is real. Vertex AI Agent Builder is real. Gemini exposes function-calling.
Zero of that is discoverable from any of these four URLs.
Two flagged anti-patterns: Invisible Product on google.com + blog.google. Agents Without Rules on the other two.
Tweet 7 (219 chars)
Top fix: publish Google-Extended on every Google-owned domain. The company that wrote the convention should be the one using it.
