ideally this should just be a file in the repo that is generated on PR using a github action (see .github/workflows). it should take all of the .mdx files in the docs folder and compile them into one single llms.txt.

i can then point https://agentstack.sh/llms-txt to serve this file for easier use with chat-with-docs, plugins, codegen, etc

@srilaasya Workflow is failing because the path to the script is incorrect.

cd docs
  python compile_llms.py
