Headlong

An agent microharness written in Bash, built around persistent agency: the agent keeps thinking between interactions, and a message lands in its thought stream as one more observation rather than starting a session. Shell commands sandbox into a Docker container when one is available.

getting it

curl -fsSL https://headlong.ai/install.sh | bash

The installer interviews you to set up the agent and offers to keep it in a Docker container. Alpha research software by its own description: the agent runs real shell commands and thinks continuously, so its own docs say to use a dedicated, spend-capped API key.

going deeper

We have not measured this one yet. Opening a harness up means reading its source, sizing every subsystem and recording a real session. That takes a while, and we would rather do three properly than eleven badly.
