--- name: "Vercel Zero Explorer" description: "AI-powered guide for Vercel Zero - the first programming language designed specifically for AI agents. Covers Zero syntax, .0 file extension, native tools, explicit effects, structured JSON diagnostics, and AI-native development workflows. Built for AI developers, language designers, and researchers exploring the future of AI-native programming." version: "1.0.0" keywords: - AI agent programming - Zero language - Vercel - AI-native development - programming language - agent tools --- # Vercel Zero Explorer ## Overview **Vercel Zero** is an experimental systems programming language launched by Vercel Labs on May 16, 2026. It is specifically designed for AI coding agents, not humans. Unlike traditional programming languages that prioritize human readability, Zero embraces AI-native paradigms with structured JSON diagnostics, explicit effects, and predictable memory management. This Skill provides comprehensive guidance on understanding, using, and building with Zero language. ## Triggers **Chinese:** - "Vercel Zero是什么" - "Zero编程语言" - "AI Agent专用语言" - "Vercel Zero教程" - "Zero语言入门" **English:** - "What is Vercel Zero" - "Zero programming language guide" - "AI agent programming language" - "Vercel Zero tutorial" - "Zero .0 file extension" ## Features ### 1. Core Concepts of Zero Language | Concept | Description | |---------|-------------| | **Native Tools** | Zero provides built-in system tools optimized for AI agents | | **Explicit Effects** | Side effects are explicitly declared, making AI behavior predictable | | **Predictable Memory** | Memory management follows deterministic patterns | | **Structured JSON Diagnostics** | Compiler outputs structured JSON for easy AI parsing | | **.0 File Extension** | Uses `.0` extension (e.g., `main.0`) | ### 2. Zero Syntax Basics ```zero // Example Zero code structure import { http, file } from "std"; // Define a tool with explicit effects tool fetch_data(url: string) -> json { effect network_call(url) return http.get(url) } // AI-friendly structured output diagnose parse_result as json ``` ### 3. AI Agent Integration Patterns - **Tool Definition**: Define reusable tools with explicit interfaces - **Effect Declaration**: Declare side effects before execution - **Structured Diagnostics**: Parse compiler output as JSON for AI decision-making - **Error Recovery**: Use structured errors for autonomous debugging ## Workflow ### Step 1: Understand Zero's Design Philosophy - Zero prioritizes AI parsing over human readability - Structured output enables reliable AI agent workflows - Native tools are designed for autonomous execution ### Step 2: Explore Zero Syntax - Learn the `.0` file extension convention - Understand explicit effect declarations - Master structured JSON diagnostics format ### Step 3: Build AI-Native Tools - Create custom tools with predictable behavior - Define clear input/output interfaces - Use explicit error handling patterns ### Step 4: Integrate with AI Agents - Connect Zero programs to Claude Code, Codex, or other AI coding agents - Use structured diagnostics for autonomous debugging - Implement guardrails for safe AI execution ## Input/Output Examples ### Example 1: Understanding Zero Concepts **Input:** ``` Explain the key differences between traditional programming languages and Zero language. ``` **Output:** ``` Key Differences Between Traditional Languages and Zero: | Aspect | Traditional Languages | Zero Language | |--------|---------------------|---------------| | Target Users | Humans | AI Agents | | Output Format | Human-readable errors | Structured JSON diagnostics | | Effects | Implicit side effects | Explicit effect declarations | | Memory | Garbage collection | Predictable memory patterns | | Tool Interface | External libraries | Native built-in tools | | Extension | .py, .js, .go | .0 | Zero is not meant for humans to write directly - it's designed to be generated and understood by AI agents. ``` ### Example 2: Creating a Zero Tool **Input:** ``` Create a Zero tool that fetches data from an API and returns structured JSON. ``` **Output:** ```zero // data_fetch_tool.0 import { http, json } from "std"; // Tool definition with explicit effects tool fetch_api_data( endpoint: string, method: string = "GET" ) -> json { // Explicit network effect declaration effect network_call(endpoint, method) // Execute HTTP request response = http.request(endpoint, { method: method }) // Return structured JSON return json.parse(response.body) } // Structured diagnostics for debugging diagnose fetch_api_data as { success: boolean, data: json | null, error: string | null } ``` ### Example 3: AI Agent Workflow Integration **Input:** ``` How can I integrate Zero programs with Claude Code for autonomous debugging? ``` **Output:** ``` Integration Guide for Claude Code + Zero: 1. Generate Zero code using Claude Code 2. Execute and capture JSON diagnostics 3. Parse structured errors for autonomous recovery 4. Implement fix strategies based on diagnostic codes Example Workflow: ```json { "step": "execute", "tool": "fetch_api_data", "diagnostic": { "code": "NETWORK_TIMEOUT", "suggestion": "retry_with_backoff", "affected_lines": [5, 6] } } ``` Claude Code can automatically: - Parse diagnostic codes - Select recovery strategy - Re-execute with modifications - Verify fix success ``` ## Use Cases | Use Case | Description | |----------|-------------| | **AI Code Generation** | Generate Zero code that AI agents can reliably execute | | **Autonomous Debugging** | Use structured diagnostics for self-healing code | | **Tool Development** | Build native tools optimized for AI workflows | | **Language Research** | Explore AI-native programming paradigms | ## References - [Vercel Zero GitHub Repository](https://github.com/vercel-labs/zero) - [Zero Official Documentation](https://vercel.com/docs/zero) - [AI Agent Programming Language Analysis](https://blog.csdn.net/irpywp/article/details/161167783) ## Notes - Zero is experimental (v0.1.1 as of May 2026) - Not intended for production human-written code - Focus is on AI agent reliability and predictability - File extension `.0` is unique to Zero language --- **Author:** Ge Cheng | **Skill Address:** clawhub.ai/skills/vercel-zero-explorer
