Show HN: NiftyAgent – Single file agent CLI under 500 LOC

I built this as I wanted to see how little setup is needed for a useful coding agent which I could use as a baseline for experimenting with different context management or task completion strategies.

The whole thing is under 500 nodejs lines and has no framework or libraries as dependencies. Its basically a loop with a small set of tools to read/edit files.

The interesting part to me is being able to quickly iterate on agent architectures without being too committed to an existing implementation.

Curious what others think of it.
