alt Hacker NewsRe: lessons from coding agents, we're building some of the key abstractions like sandboxes, filesystem, skills/knowledge as Mastra primitives in over the next month.
For any agent you're shipped to production though you probably want a harness that's open-source so you more fully control / can customize the experience.
I think that’s fair, totally, but I also think a Skill would be considered a primitive in and of itself by Anthropic. So to me it’s still wrapping an open primitive. Anyway, trade offs.
