Traditional Context Engineering — 2024–2025 Snapshot

Status: provisional historical research snapshot

This skill is a provisional historical research snapshot of context-engineering practice as published in 2024–2025. It is NOT normative. Do not apply it prescriptively to current frontier models without re-verification. On any conflict, OpenRig current skills, explicit user rulings, and directly measured OpenRig practice PREVAIL over this document. Treat these areas as particularly suspect pending re-verification: compaction/summarization guidance, minimal-upfront versus broad orientation, just-in-time lookup assumptions, fixed context ceilings, and single-agent versus multi-agent advice.

Curated distillation of the best publicly available expertise on context engineering for coding agents, drawn from primary sources at Anthropic, OpenAI, and leading practitioners (Manus, Cognition, Chroma, LangChain, Drew Breunig, and others). Load on the moments the description names; it is deliberately not part of any base walk.
