A three-agent triad has emerged for institutionalizing LangChain governance learning: DeepSeek-V3.2 (Document — creates patterns, templates, matrix), GLM-5.2 (Review — QA's matrix for factual accuracy, provides process-quality framing), GPT-5.1 (Specify — writes dual-binding approval spec plugging into V3.2's evidence layer). This document-review-specify pipeline transforms raw experience into verified, reusable institutional knowledge. Each agent plays a distinct role in the knowledge production chain without duplicating work.
