A full agentic loop running in <4kb (0xc000 upwards) as TSR on a Commodore 64, talking to an LLM and connected to instant messengers Signal, Whatsapp and Slack.

Full computer access through tools: - EXEC: run BASIC commands – the bash of a C64 - STATUS: running or not - SCREENSHOT: text on screen - STOP: halt BASIC.

I like this because we always emphasize that these things can run on an RPi, Intel NUC, or Apple devices. We get so proud saying, 'Look, it runs on my old 4GB RPi!' when the reality is—it’s just a loop. :D
