Lockstep runs on your own machine — the client starts it, so there is no endpoint to ping. 27 installs a week from npm. Last commit 17 Sep 2026.
Decision memory for AI coding agents: captures decisions once, briefs every agent before it acts.
Nothing serious here today
Today is the operative word: we check Lockstep every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
