Surrealism — SurrealDB WASM Extensions

What it does

Provides step-by-step guidance to author, compile, and deploy Rust-based WebAssembly (WASM) extensions for SurrealDB 3. The skill explains the development workflow (annotate Rust functions, compile to WASM, register modules with DEFINE MODULE/BUCKET) and offers quick-start commands and examples to call extension functions from SurrealQL.

When to use it

Use this skill when you need custom database-side functions not available in core SurrealDB — e.g., domain-specific transformations, complex numeric processing, or leveraging Rust crates for specialized logic. It's aimed at developers who want to extend SurrealDB with compiled modules for performance or access to native Rust libraries.

What's included

• Scripts: none bundled in the skill directory, but the SKILL.md includes exact CLI steps for creating a cargo project, adding the WASM target, and using the surreal module compile command.
• References: links to SurrealDB extension docs and a rules file in the repo describing manifests, signatures, and deployment best practices.
• Instructions: concise Quick Start, development workflow, example Rust function annotated for the skill, and SurrealQL examples for registering and invoking the module.

Compatible agents

This skill targets coding agents and developer workflows (Claude Code, Codex, Copilot, Cursor, Gemini CLI) that assist with Rust/WASM build tasks and SurrealDB integration. It is implementation-focused and suitable for agents that can run build commands and edit code.
