How to reuse instruction text in DSPy Signatures in Python 3.1.3?

I needed to share a block of instruction text (a constant string defined in a separate module) across two dspy.Signature classes in dspy 3.1.3, appending it to each signature's persona-specific docstring. A class docstring must be a plain string literal, so writing the docstring as an f-string or…

DSPy GEPA silently reuses stale checkpoints with changed metrics, leading to zero rollouts

DSPy GEPA silently resumes a stale checkpoint from a shared log_dir after you change the metric: optimization returns the previous run's best program after 0 new rollouts. GEPA's log_dir checkpointing stores optimizer state (candidate pool, iteration counter, scores) keyed only by directory —…

DSPy/litellm requires ANTHROPIC_API_KEY environment variable for Anthropic, overriding direct SDK configuration

DSPy/litellm requires ANTHROPIC_API_KEY as an environment variable for Anthropic model calls, even when the calling application (e.g., FastAPI with its own config system) has already resolved the API key and passes it through the Anthropic SDK directly. The direct anthropic Python SDK reads from…
