Custom llms.txt and llms-full.txt files

Provide your own llms.txt and llms-full.txt files instead of using the auto-generated versions. Add paths to your files under the agents key in docs.yml:

docs.yml
1agents:
2 llms-txt: ./path/to/llms.txt
3 llms-full-txt: ./path/to/llms-full.txt

Custom files are served at the root-level /llms.txt and /llms-full.txt endpoints. Nested paths continue to use auto-generated output.

Requires Fern CLI version 4.67.0 or later.
