MissingFactError may be too strict

[segfly]

Problem Description

AI conditions enforce that at least 1 fact placeholder is present. This may be too strict for some use cases, where a rule wants to use the internal knowledge of an LLM (especially if fine-tuned) without referring to any additional context.

Steps to Reproduce the Problem

condition("Is the moon round?")

Results in:

MissingFactError: An AI condition requires at least one referenced fact.

Expected Behavior

AI conditions without a fact should only issue a warning, not an error.

Environment:

vulcan-core: 1.1.4

Additional context

None
