Vercel Updates Agent Browser to Serve Dynamic Runtime Tool Instructions

· Updated

Vercel, a frontend cloud platform and creator of the AI SDK, released a new skills command for agent-browser, its browser automation CLI for AI agents. The update replaces static SKILL.md files with a runtime service that provides version-matched instructions directly from the CLI.

Agents often fail when their cached instructions do not match the current tool syntax. By serving skills (reusable capabilities packaged for AI agents) at runtime, Vercel ensures the agent's manual is always in sync with the software. This shift improved agent compliance from 85% to 100% in internal evaluations.

You can install the new thin discovery skill using npx skills add vercel-labs/agent-browser. This integration works with agentic tools like Claude Code, Cursor, and Windsurf. Once installed, agents will automatically fetch the latest command syntax and instructions using the agent-browser skills get command.

New command: agent-browser skills Cached skills go stale when the CLI updates. Now the CLI serves skill content at runtime. One thin skill installed via: npx skills add vercel-labs/agent-browser Evals show agents pick agent-browser more often and use it correctly. https://t.co/XttpRFjY4J
