PCH Framework Adapters

Six thin OpenAI-compatibility wrappers letting developers use PathCourse Health from the AI agent frameworks they already use. Each subdirectory is its own publishable package.

The PCH gateway at https://gateway.pathcoursehealth.com/v1 is fully OpenAI API-compatible. Every adapter is a thin layer that points the framework's existing OpenAI integration at the PCH gateway. A developer with 10,000 lines of LangChain code switches by changing one line.

Publishing a new version

Python (PyPI)

cd <package-dir>                      # langchain-pathcourse, crewai-pathcourse, etc.
python -m build
python -m twine check dist/*
python -m twine upload dist/*         # production PyPI (set TWINE_USERNAME=__token__, TWINE_PASSWORD=<token>)

TypeScript (npm)

cd <package-dir>                      # langchain-pathcourse-js or pathcourse-ai-sdk
npm install
npm run build
npm publish --dry-run                 # inspect what will ship
npm publish --access public           # 2FA OTP prompt

Verifying a new release

pip install <package-name>
python -c "from <module> import <Class>; print('OK')"

npm install <@scope/name>
node -e "const p = require('<@scope/name>'); console.log('OK')"

Versioning

Each package version is independent. The PCH SDK at pathcourse-sdk / @pathcourse/sdk is on a separate version track. Bump only the packages you actually changed.
