A skill operates within an ongoing conversation, keeping humans in the loop, while a sub-agent takes a single prompt, runs independently, and delivers a final output. Four key dimensions guide the decision: iteration model, voice fidelity, human gate placement, and task frequency. Community discussions on Reddit and Hacker News add nuance — sub-agents keep context windows clean but introduce orchestration complexity and non-determinism, while skills offer reusability across agents and flows. Pattabiraman concludes that the dichotomy is often false: skills and sub-agents compose cleanly, and layering one on top of the other frequently represents the most mature design. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What's the difference between a skill and a sub-agent when building AI agent systems? A skill operates within an ongoing conversation, reading files, asking questions, and iterating with a human in the loop, while a sub-agent takes a single prompt, runs independently to completion, and delivers one final output. The choice depends on four dimensions: iteration model, voice fidelity, human gate placement, and how frequently the task repeats, with frequency giving the clearest divide between a one-off task suited to a skill and a repeatable batch job suited to a sub-agent. _Explore more takes on agent architecture patterns like skills versus sub-agents on daily.dev._ ### Why do sub-agents help avoid polluting the context window in AI agent workflows? Sub-agents always start with a clean context, unlike skills, which take into account the whole ongoing conversation. This makes sub-agents useful when a step needs genuinely separate context, permissions, or a different knowledge source, while skills remain reusable across multiple agents or conversation flows since they share conversational context. _Developers designing multi-agent systems can track these context-management patterns via daily.dev._ ## Similar posts on daily.dev - [Tools vs. Subagents: Building Effective AI Agents Without Over-Engineering](https://daily.dev/posts/tools-vs-subagents-building-effective-ai-agents-without-over-engineering-oonittab6) · Machine Learning Mastery · 1 upvotes · 0 comments - [AI Agents or Skills?
