Your agent can make a better guess.", "summary": "Pixy, a design tool, records visual context from changes made on a running website to help coding agents implement them accurately, reducing the need for verbose prompts. The tool captures the target element, property, old and new values, viewport width, and scope, allowing the agent to decide how to implement the change based on the repository.", "body_md": "You are looking at a page thinking, \"Move this down, use the same spacing as that card, but only on mobile.\" You know exactly what you mean because you're looking at it. Your coding agent is looking at a repository.\n\nYour coding agent cannot read your mind\n\nSo you translate what you see into a prompt. Which element, which page, which breakpoint, this instance or every instance. Add a screenshot and the agent can see the pixels, but it still has to connect them to the right element, component, rule, and scope.\n\nFor visual work, the useful context is already there when you make the change. You know the target, the property, the old and new values, the viewport width, and whether you changed one element or a shared rule. Throw that context away and you get to describe it all again in English.\n\nThis is the idea behind [Pixy](https://pixydesignapp.com/). Make the change on the running site and Pixy records the visual context for your coding agent. The agent still decides how to implement it because it has the repository and knows whether that 16px lives in Tailwind, a CSS module, a prop, or somewhere in `globals.css` you'd rather not discuss.\n\nYou already made the change. Describing it again just gives your agent another chance to misunderstand you.", "url": "https://wpnews.pro/news/you-can-write-a-better-prompt-your-agent-can-make-a-better-guess", "canonical_source": "https://dev.to/astroscout/you-can-write-a-better-prompt-your-agent-can-make-a-better-guess-2hni", "published_at": "2026-09-09 20:53:38+00:00", "updated_at": "2026-09-09 21:11:49.071028+00:00", "lang": "en", "topics": ["developer-tools", "ai-agents"], "entities": ["Pixy"], "alternates": {"html": "https://wpnews.pro/news/you-can-write-a-better-prompt-your-agent-can-make-a-better-guess", "markdown": "https://wpnews.pro/news/you-can-write-a-better-prompt-your-agent-can-make-a-better-guess.md", "text": "https://wpnews.pro/news/you-can-write-a-better-prompt-your-agent-can-make-a-better-guess.txt", "jsonld": "https://wpnews.pro/news/you-can-write-a-better-prompt-your-agent-can-make-a-better-guess.jsonld"}}
