Regenerate the Arthur GenAI API Client

The arthur_genai_client package under python/src/ is auto-generated and gitignored. It must be present before running tests, linting (mypy), or using prompt management features.

Steps

1. Check prerequisites

node --version   # needs Node.js (any recent LTS)
java -version    # needs Java 11+

If either is missing, tell the user to install them and stop.

2. Generate and install

From the arthur-observability-sdk/ directory:

./scripts/generate_openapi_client.sh generate python
./scripts/generate_openapi_client.sh install python

generate python will:

• Install / update openapi-generator-cli via npm if needed
• Read genai-engine/staging.openapi.json
• Write the generated package to python/src/arthur_genai_client/

install python runs uv sync to register the generated package in the venv.

3. Verify

python -c "from arthur_genai_client.models.agentic_prompt import AgenticPrompt; print('OK')"

If that prints OK, the client is ready. If it errors, re-run step 2.

Notes

• Do not hand-edit any file inside python/src/arthur_genai_client/ — changes will be lost on the next regeneration.
• The generator requires the GenAI Engine spec at genai-engine/staging.openapi.json. If that file is missing, update it from the running GenAI Engine: curl http://localhost:3030/openapi.json > ../genai-engine/staging.openapi.json
