Right you are, Ken!

Why is everyone making their own code execution agent runtime engines I have an entire project built on top of openshell already, why not first come up with a sandboxing policy design, like unix did, and then build on top of that.

Currently all project do tend to agree on what and how they work but certain things being different makes porting tedius, if all of them have a bare minimum subset common amongst them it would be much easier to switch, and validate security surface area.

I feel like there are more vulnerabilities in this vibe coded slop sandboxes, and it's more likely everyone one of us trusting them to build projects around them will shoot our foot off once a cve is hit in one that's common in all of them but since they are all slop copies someone will have to figure out how they apply to all others and then manually fix it properly, and if one of them makes a CVE public it will leave dozens of these runtimes open to exploits.

I wish the best to my future self with regards to security I feel like we are completely screwed. Since we can no longer depend on upstream for security.
