Why agent access matters

The web is no longer only for human browsers. Coding agents, research assistants, and AI search crawlers fetch curated surfaces first: llms.txt, markdown indexes, skill files, and structured data, not your full chrome-heavy HTML.

1. Discovery is a product surface

If agents cannot find a clean index of what you offer, they guess. Guessing produces wrong answers about your product. Shipping agent-readable files is infrastructure, like HTTPS or sitemaps, not a growth hack.

2. Training bots ≠ search bots

OpenAI, Anthropic, and others split crawlers: training, search indexing, and user-initiated fetches. Blocking GPTBot does not automatically block OAI-SearchBot. Conflating them is how teams accidentally disappear from AI answers while “protecting” the wrong thing.

3. Diagnosis without a fix is incomplete

A grade only helps if you can act. Paste-ready robots.txt, llms.txt, JSON-LD, and an agent fix prompt turn a scan into progress, without promising citation miracles.
