The agent engineering platform.
This period is measured from GitHub’s rebuilt star history — one point per week — because our own daily snapshots do not reach this far back yet. Period boundaries can be off by up to half a week; the repository page prints the real start date for each period. So far the history has been fetched for 12,567 of 62,640 tracked repositories, and only those can be ranked in this period.
Star counts measured between 00:28 and 06:42 (BKK).
