Headlong launches a persistent agent microharness
Headlong is an open-source agent harness designed around persistent agency, where an agent keeps thinking in a self-guided loop between external interactions instead of only responding to requests. The project is presented as alpha research software, written in under 10K lines of Bash, and intended to run in a sandbox with a dedicated API key because it can execute shell commands.
