The early June 13 snapshot is almost a table of contents for agent engineering. addyosmani/agent-skills leads at #1 (+11), followed by NVIDIA’s SkillSpector at #2 (+10) and headroom at #3 (+9). That ordering is useful: the attention is no longer only on chat surfaces or coding agents. It is also on the small operating parts around them: reusable skills, scanners, context compression, and code graphs.
There is a rough edge in the same top ten. elder-plinius/CL4R1T4S sits at #4 with leaked prompt material, while two installer style repos for consumer apps appear lower down. Treat this board as an early signal, not a quality ranking. The cleaner read is that the agent stack is being pulled in two directions at once: better local workflow components such as architect-loop, last30days-skill, and codegraph, plus a recurring supply of noisy projects that need stricter review before anyone runs them.
