Assertion-aware metrics and optimization

[manishshettym]

Tasks

• option to enable assert-aware-metric for each assert/suggest (i.e., optimizable):
  dspy.Suggest(constraint, msg, is_metric)
• track suggest/assert failures during evaluation
• propagate suggest/assert failures as an attribute of a bootstrapped program
• penalize optimization score according to the number of failures
• incorporate feedback traces into compilation
