Why it matters
Prompt injection remains the top-ranked LLM vulnerability, and foundational explainers help defenders understand how context windows blend trusted and untrusted input, but this piece offers no new technique or finding.
An introductory explainer by 7s26Simon covering prompt injection (listed as LLM01:2025 on the OWASP Top 10 for LLMs) and the concept of the context window, describing how system, developer, user, RAG, and tool inputs share a token budget the model can process at once. The piece is part one of a series and sets up foundational concepts rather than demonstrating a specific attack.
