[cornerstone] Phase 4.7f — Port Code Generation & Execution to Python#7971
Conversation
## What Ports the `generate_and_execute_code` agent function from TypeScript to Python, completing the final function group in Phase 4.7. ## Why Completes all six agent function groups (text, image, video, speech, music, code). Code gen reuses the existing `from_pidgin_string` / `conform_body` / `stream_generate_content` pipeline from `generate_text`, so no new infrastructure was needed. ## Changes ### `opal-backend-shared` - **Modified** `functions/generate.py` — adds `_define_generate_and_execute_code` (Gemini + `codeExecution` tool, optional `googleSearch`, handles `inlineData` file outputs and `codeExecutionResult` error tracking). Updated instruction text with code gen prompt guidelines. Wired into `get_generate_function_group`. - **New** `tests/test_code_gen.py` — 16 tests covering all code paths ### `PROJECT_CORNERSTONE.md` - Marks Phase 4.7f as complete ## Testing ```bash cd packages/opal-backend-shared && source .venv/bin/activate python -m pytest tests/test_code_gen.py tests/test_generate.py -v ``` All 36 tests pass (16 new + 20 existing `generate_text`).
