Phases Agents runs on your own machine — the client starts it, so there is no endpoint to ping. 70 installs a week from pypi. Last commit 1 Sep 2026.
Deterministic skill selection: local discovery, strict validation, every skill classified.
Today is the operative word: we check Phases Agents every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
