Apply LangChain's four context operations — write, select, compress, isolate — as a checklist

Taskade·low signal

LangChain formalized context engineering into four operations: write (persist context externally), select (retrieve only what's relevant), compress (summarize/compact long history), and isolate (separate contexts per agent). Treating these as a design checklist targets the real cause of most agent failures in 2026 — context failures, not model failures — and gives a vocabulary for deciding which lever a given bug needs.
