Create Classifier Skill

Purpose: Training infrastructure for task-specific classifiers that improve extractor pipeline accuracy through ML-based detection instead of regex/heuristics.

Overview

This skill provides end-to-end infrastructure for creating, training, and deploying classifiers for extraction tasks:

• Data Collection: Mine labeled data from successful pipeline runs
• Training Templates: Vision, text, and hybrid classifier architectures
• Execution Feedback: GRPO-style training with pipeline success as reward
• Confidence Routing: Automatic fallback to heuristics when confidence is low
• Shadow Deployment: Compare classifier vs heuristics before full rollout

Success Story: Table Strategy Classifier

The table extraction classifier (S05) achieved:
