 This structured approach allows LLMs to efficiently process your documentation at a high level and locate relevant content for user queries, improving the accuracy and speed of AI-assisted documentation searches.
 
 <Note>
-  Automatically generated `llms.txt` files cannot exceed 100,000 characters. As a file approaches this limit, Mintlify shortens page descriptions first, then drops entries and appends a note listing what it omitted. This limit does not apply to `llms-full.txt`. To list every page without truncation, add a [custom `llms.txt` file](#custom-files) at the root of your project.
+  Automatically generated `llms.txt` index files cannot exceed 100,000 characters. For large documentation sites, Mintlify splits the index into linked files under `/_llms/` so agents can discover every page without loading one oversized file. This limit does not apply to `llms-full.txt`.
 </Note>
 
+If you use a reverse proxy or maintain a path allowlist, forward `/_llms/*` in addition to `/llms.txt` so agents can follow the generated index links. For documentation hosted at a base path, forward `<base-path>/_llms/*` instead. Mintlify-managed custom domains do not require additional configuration. See [Reverse proxy](/deploy/reverse-proxy#routing-configuration) for routing guidance.

 Mintlify serves these files under your base path, like `<your-subdomain>.mintlify.site/docs/llms.txt`. They are available on your domain under your subpath, like `your-domain.com/docs/llms.txt`, through your main subpath route.
 
+The `/docs/*` route also covers generated `llms.txt` indexes under `/docs/_llms/*`. If your proxy uses a more granular path allowlist instead of forwarding all `/docs/*` requests, include `/docs/_llms/*` so agents can follow every index linked from `/docs/llms.txt`.
+
 The `/.well-known/skills/*`, `/.well-known/agent-skills/*`, `/skill.md`, `/llms.txt`, and `/llms-full.txt` routes are optional. Include them only if you also want to serve these files at root paths on your domain, like `your-domain.com/llms.txt`. Each root path maps to the file under your base path on your Mintlify subdomain.
