## Purpose

Source: AI-written repository summary; verify against source.

> DeerFlow is an open-source super-agent harness (version 2.0, a ground-up rewrite) that orchestrates sub-agents, persistent memory, sandboxed execution, and extensible skills to handle long-horizon tasks that take minutes to hours—combining research, coding, and content creation in a single framework.

## Main parts

> Frontend & UI: Next.js-based web interface for agent interaction and result visualization.

## Evidence gaps

> RepoPilot has not run the setup commands or tests.
> Files marked “likely” are guessed from their names.
> Could not capture README.md: source unavailable or larger than the capture limit. Open its source link to check setup.
> An installation or usage excerpt was not captured. Read the README for how to use the published project.
> Runtime versions and other prerequisites were not captured.
> Setup has not been executed. Environment variables, external services and command order may require additional source documentation.
