Why it matters

A lightweight, dependency-free detector for indirect prompt injection gives defenders a runnable pattern-matching baseline for screening untrusted content before it reaches an LLM or agent.

Cheikh seck describes building a prompt injection detector in Go using only the standard library — 29 regex rules and no ML models — tested against a product page seeded with 12 attack techniques drawn from a 2026 CrowdStrike prompt-injection taxonomy report. The accompanying code is published on GitHub (github.com/cheikh2shift/go-snippets/tree/main/prompt-injection).
