# Deep Agents combines plans, files, memory, and subagents

## Observation

The open-source Deep Agents stack packages common long-horizon primitives on top of LangGraph and LangChain.

## Why it matters

Repeated agent primitives are consolidating into a reusable runtime layer, reducing the need to rebuild planning and context management for each application.

## Provenance

Normalized from QWG AI Telegram message 2582. The original Russian-language record remains available at https://t.me/qwgai/2582.
