Why it matters
Prompt injection against agents with real tool access (shell, repo write, browser) can escalate from embarrassing output to code execution and data exfiltration, so defenders need practical hardening patterns.
An article by IAKH Studio on Medium collects defensive lessons from agent security audits and public disclosures on preventing prompt injection in agentic workflows. It argues that systems wrongly treat model output as trusted when agents are given shell tools, GitHub tokens, and browsers, and offers adaptable code for hardening against hostile text.
