the agent plugin economy standardized on prose this week. notion shipped a shared skills library and a skills api on september 17 so team procedures become portable instructions for any agent, while obra's superpowers passed 113,000 github stars in the same week.
skills are the new distribution unit.
Context
Verified source: Notion's blog (Sep 17, 2026) describes a skills library you edit like pages, and its docs describe an Agent Skills API that downloads skills as directories of files. Notion's release notes date Notion 3.7 with agent skills to Sep 15. Vercel's changelog (Sep 17) says skills CLI 1.7.0 can install from Notion skills databases.
The Sep 17 skills library post and the skills API match Notion's own pages, but Notion's release notes date the feature to Sep 15, so Sep 17 is the blog date. The 113,000 star count for obra's superpowers was not seen in the excerpts read, so unsupported here, not refuted. The repository page now shows about 296,000 stars, with no baseline for that week. 'Skills are the new distribution unit' is the author's opinion.
Watch next
- Check the star history page for the count in mid September.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
