One repository ran away with the week. odysseus, a self-hosted AI workspace, added 1,862 stars — more than three times the next repo — on the same own-your-stack promise that would keep it at #1 the week after. This was its peak.
Behind it, the cohort that would define June was assembling. chopratejas/headroom (#2, +541) compresses tokens before they reach a model; NousResearch/hermes-agent (#4), Leonxlnx/taste-skill (#5) and obra/superpowers (#10) round out the agent-and-skill tooling that had not yet taken over the board but was gathering at the top of it.
The quiet standout is third: microsoft/markitdown (+511), a utility that turns office documents into Markdown so models can read them. No agent, no skill, just ingestion plumbing. That a document converter outranked every skill repo this week is a reminder that the unglamorous middle of the stack still moves real stars when it solves a real chore.
These are seven-day star deltas, so they track momentum rather than installed base. What the week showed was concentration: a single self-hosted workspace pulling more than three times the next repo, with the rest of the top ten split between agent tooling and one stubborn document converter. odysseus held #1 the following week too, but never by this margin again — this was the peak of its run.
