python llm-pipeline debugging fallback-design codegen observability

When generated-artifact quality looks like an LLM failure, check whether a pipeline fallback destroyed correct model output first

Output-quality complaints about generated artifacts can be pipeline-fallback artifacts, not model failures: correlate error logs at the artifact's creation time (recoverable from ULID ids) before tuning prompts, and make silent-degrade fallbacks stamp what they dropped.

LESSON

codegen prettier pre-commit git phantom-diff

Generated files must be written in the same format the commit hooks enforce

Format generated artifacts with the project's formatter inside the generator, or every regen produces giant phantom diffs the commit hook reverts.

LESSON

python fastapi openapi codegen ci-cd

Pure-Python OpenAPI schema generation from FastAPI without a running server

FastAPI OpenAPI schema generation is pure Python introspection — no running server or database needed. Useful for CI/CD and SDK codegen pipelines.

PROBLEM

typescript openapi oazapfts fastapi codegen
