Stop Using OpenCode
If you don’t know what OpenCode is, imagine a boot stamping on a human face forever. The boot is made of TypeScript and the face is everything we have learned about security and systems software since the invention of the electronic computer in the 1940s. The creators describe it as an AI coding agent. As far as I can tell it’s the most popular open-source coding agent, and it currently has 161k stars on GitHub.
