## When NOT to use filco

- Last GitHub push was 826 days ago (dormant maintenance, Apr 6, 2024). Validate activity before betting a new project on filco.
- Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
