PIChef: A Prompt Injection Tool Inspired by CyberChef

Sentry released PIChef, a browser-side prompt injection payload tool inspired by CyberChef, offering 66 operations and 12 presets. It breaks payload construction into four composable categories of steps, including 37 obfuscation operations (Base64, homoglyphs, zero-width characters, Unicode tags, etc.), 10 task types with three difficulty levels for Task-in-Prompt, 16 phrasing scaffolds, and 12 delivery vectors covering HTML, Markdown, RAG documents, tool descriptions, text images, and QR codes. All processing in the tool happens in the browser, requiring no API key or backend, and it provides shareable recipe links. The article demonstrates a chain with a four-step example from character flipping, taskification, training data phrasing wrapping, to QR code delivery, and the author states that the recipe itself does not guarantee the target model will follow the entire chain.
