Agents are becoming a new kind of user. They read docs, call tools, run commands, inspect state, and act on someone’s behalf. That changes how software should be built. Using examples from Codex and OpenAI’s plugin ecosystem, Corey Ching will show how to make products useful to agents: when to reach for a skill, MCP server, app, CLI, or a focused combination. The best agent experiences provide the right capabilities that give the agent the missing piece it needs to finish the job.
