Expert guide for ephemeral WebAssembly (WASM) and isolated micro-runtime sandboxes to securely execute AI-generated code, validate database migrations in-memory, and perform sub-millisecond fuzzing / Panduan ahli sandbox WebAssembly (WASM) efemeral dan micro-runtime terisolasi untuk eksekusi kode AI yang aman, validasi migrasi database in-memory, dan fuzzing sub-milidetik.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ephemeral-wasm-sandbox-executor — vibes-plug Skill [English](#english) | [Bahasa Indonesia](#bahasa-indonesia) --- <a name="english"></a> ## English ### Orchestration & Integration Connects and orchestrates with `brainstorming`, `zero-to-prod-orchestrator`, `autonomous-tdd-debugger`, `wasm-edge-computing-expert`, `autonomous-red-teamer`, and `production-ready-hardener` to safely execute untrusted AI-generated code, simulate database migrations in-memory, and run security fuzzers with zero host blast radius. ### Description Production guide for architecting ultra-low latency, zero-trust ephemeral sandboxes powered by WebAssembly (WASM) runtimes (such as Wasmtime, Extism, and PGlite/SQLite WASM). Provides agents with instant execution environments (<5ms startup overhead) to dry-run database migrations, test adversarial inputs, execute generated logic, and evaluate potential security hazards without Docker container overhead or risk to host systems. ### Trigger Conditions Activate this skill when: - Testing AI-generated code snippets or regex patterns that could trigger infinite loops or ReDoS. …

How to install
mdr add roedyrustam/vibes-plug/ephemeral-wasm-sandbox-executor@sha256:fe8d67ef9b6b995bThe line at the top of this page pins the label v4.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
