| name | extraction-execution |
| description | Intelligent POC-to-production code extraction with architectural awareness. Analyzes dependencies, adapts patterns, makes extraction strategy decisions (copy/adapt/rewrite), maintains system coherence. Performs pre-extraction analysis, transformation reasoning, quality gate enforcement, evidence-based commits. Use when extracting code requires understanding architecture, adapting patterns, threading parameters, or maintaining coherence across modules. Triggers on understand and extract, analyze dependencies, adapt pattern, extraction strategy, architectural extraction, intelligent migration. |

VERSION
2.0.0[2025-11-02]::REWRITE[mechanical→intelligent]+ADDED[Phase_0+pattern_catalog+coherence+real_metrics]+VALIDATED[Phase_2A/2B]
The hard part isn't copying files—it's understanding what to extract, how to adapt it, and ensuring it fits. This skill handles the 95% requiring thought, not the 5% that's mechanical.
