GitHub·medium signal

LangChain (139,113 stars) now describes itself as 'The agent engineering platform,' signaling a continued pivot from a prompt/chain library toward full production agent orchestration. The repositioning tracks the 2026 shift in which frameworks compete on agent tooling rather than chaining primitives. For builders, it's a signal that LangChain is repositioning against newer agent-native stacks.
