We built most of our 'agents' wrong. At Dust, we had packaged capabilities as standalone agents that other agents could call. Worked fine. But it meant every capability lived in a silo. Then we realized: what if instead of building 50 specialized agents, we built Skills—reusable packages of tools and instructions that any capable agent could compose together? Same underlying capability. 10x the flexibility. Example: Deep Dive used to be its own agent. Now it's a Skill. Any agent can access those research capabilities and combine them with other tools on the fly. The lesson for anyone building: before you create another agent, ask if you're actually building a reusable skill that should be composable. More in comments below.
