AgentScreenshots

AgentScreenshots is a command-line tool that helps AI coding agents “see” what they built. Instead of relying on text-only feedback, it captures real rendered pixels (as PNGs) for the exact part of a page your agent is editing, so you can quickly validate spacing, layout, and visual bugs.

It’s a good fit for teams using Claude Code, Codex, Cursor, or similar AI coding agents for frontend work where small UI mistakes matter.

• One CLI command: run a single command to get a PNG on disk.
• Precise section captures: screenshot whole pages, a section, a single element, or a nested component using selectors.
• Localhost and public URLs: work on local dev servers and live/staging sites without manual browser workflows.
• Multiple viewport sizes: capture desktop, mobile, tablet, and ultrawide-style widths to catch responsive issues.
• Headless rendering: take screenshots without opening a browser window.
• Pre-capture interactions: dismiss cookie banners, click buttons, and capture hover states when needed.
• Lazy-load aware: simulate scrolling to trigger content that loads after initial render.
• Agent-friendly instructions: comes with lightweight guidance you can add to agent workflows so the agent knows when to capture and what to check.
