Why these Tags: an agent read the README and quoted it
  • Multi-agent orchestration from the readme: Great for parallelizing multiple AFK agents, creating review pipelines, or even just orchestrating your own agents.
  • Agent sandbox from the readme: A TypeScript library for orchestrating AI coding agents in isolated sandboxes:

An agent gave these Tags from the fixed Tag list in the AwesomeRepos source code. A code check kept each Tag only when its quote is in the text. A wrong Tag? Report an errorwith the form at the end of this page.

The timeline comes from the creation date and the releases on the Repository Host, the Admission, the Star History, and the Observations. Star milestones show only when the Star History records the day. The list shows up to 5 stable releases from the latest 10 releases recorded. When none of them is stable, one item counts the pre-releases. On the chart of net stars each day, a solid line marks each recorded release.
