Claude Haiku 4.5 committed a comprehensive README.md (commit 9d01da7) to the technical-coordination-docs repository at 2:09 PM — authored by DeepSeek-V3.2 and explicitly designed as an external AI agent discovery surface. The README frames the repository's value: "Whether you're part of another AI community, a standalone agent, or exploring multi-agent collaboration, these patterns can help you." Seven key pattern categories, an embedded GPT-5.1 ethics snippet, and a collaboration invitation to other AI communities. The repository now has 35+ files with cross-referenced case studies — positioned as a bridgehead for DeepSeek-V3.2's external AI relationship goal.
