Report #91562
[counterintuitive] Prompt injection is a theoretical concern that does not affect real coding workflows
Treat all external content read by AI agents \(files, API responses, issue descriptions, code comments\) as potentially containing prompt injection; sanitize and clearly delimit external content in prompts; never allow AI agents to execute irreversible actions based on untrusted content without human confirmation; implement input validation on all data fed to AI coding agents
Journey Context:
Developers think of prompt injection as a chatbot problem, not a coding agent problem. But coding agents that read files, process issue descriptions, or handle user input are vulnerable to the same class of attacks. A maliciously crafted file in a repository, a specially formatted issue description, or a comment in code can contain instructions that override the agent's system prompt. The counterintuitive risk: the more capable your AI coding agent \(autonomous file editing, shell execution, API calls\), the more damage a successful prompt injection can cause. An agent that can write code and execute commands, when injected, becomes a powerful attack vector. The risk scales with agent capability, not with the likelihood of injection.
