Show HN: ProofShot – Give AI coding agents eyes to verify the UI they build

Summary

Open-source, agent-agnostic CLI that gives AI coding agents eyes. Your agent builds a feature — ProofShot records video proof it works. Works with Claude Code · Cursor · Codex · Gemini CLI · Windsurf · GitHub Copilot · any agent that runs shell commands AI coding agents build UI features blind. They write code but can't verify the result looks right, works correctly, or throws no errors. ProofShot closes the loop: an open-source CLI that plugs into any AI coding agent and gives it a verification workflow — test in a real browser, record video proof, collect errors, and bundle everything for the human to review. The human gets a video recording, screenshots of key moments, and a report of any console or server errors found. View artifacts locally, or run proofshot pr to upload everything to the GitHub PR as an inline comment. No vendor lock-in. No cloud dependency. The interactive viewer: video recording with scrub bar, action markers, and step-by-step timeline npm install -g proofshot proofshot install The first command installs the CLI and agent-browser (with headless Chromium). The second detects your AI coding tools and installs the ProofShot skill at user level — works across all your projects automatically. Three-step workflow: start, test, stop. # 1. Start — open browser, begin recording, capture server logs proofshot start --run "npm run dev" --port 3000 --description "Login form verification" # 2. Test — the AI agent drives the browser agent-browser snapshot -i # See interactive elements agent-browser open http://localhost:3000/login # Navigate agent-browser fill @e2 "test@example.com" # Fill form agent-browser click @e5 # Click submit agent-browser screenshot ./proofshot-artifacts/step-login.png # Capture proof # 3. Stop — bundle video + screenshots + errors into proof artifacts proofshot stop The skill file teaches the agent this workflow automatically. The user just says "verify this with proofshot" and the agent handles the rest. Each session produces a ...
