This AI Agent Can Actually Self-Evolve… Just Watch
David Ondrej demos a self-evolving agent — an agent that modifies its own prompts/tools as it runs.

Ondrej walks through an agent that rewrites its own scaffolding as it works.
What is it?
A David Ondrej demo video of a self-evolving agent — an agent setup where the system modifies its own prompts, tools, or routing logic in response to its own outputs across runs.
How does it work?
Ondrej runs the agent live, points at the moments where it edits its own scaffolding, and discusses how this differs from a static prompt + tool loop.
Why does it matter?
Self-modifying agents are the next frontier past simple ReAct loops. Concrete demos (vs. tweets) help calibrate where the actual capability is in late April.
Who is it for?
Builders interested in agent self-improvement patterns.
