Headlong gives a team one continuous agent instead of separate sessions, so what one person tells it, everyone else sees next.
Why now: Laude posted the release and the sandboxing warning together on August 24.
Laude and MIT released Headlong on August 24, a roughly 10,000-line Bash harness built around one idea. The agent never stops thinking. There's no task boundary and no per-session reset. A message from any teammate arrives as one more observation in a stream the agent already holds, instead of starting a new conversation.
That changes who the agent works for. One agent holds context for an entire team, and whatever one person tells it, the next teammate to open a session can see. The upside is unprompted collaboration. The risk is that anything private said to it stays visible to whoever talks to it next.
The harness already justified itself once. Laude says their agent reviewed two teammates' in-progress branches without being asked and caught a hardcoded model name. Laude also warns the harness is bad at keeping secrets across conversations and recommends running it sandboxed on a spend-capped API key.
Both problems come from the same choice. Everyone on the team feeds into one running conversation. Run it like a contributor with read access to every branch on the team, not a private assistant.
