The pain

AI agents are vulnerable to instruction injection attacks via untrusted external content.

Who'd pay

Companies developing or deploying conversational agents, virtual assistants, and AI systems processing external content.

Signal that triggered it

"Add structural delimiters that mark externally-sourced content (tool results, incoming messages, web fetches) as data rather than instructions, to defend against prompt injection attacks."

Original post

[Feature]: Prompt injection defense at tool result and message boundaries

Published: Apr 8, 2026

Add structural delimiters that mark externally-sourced content (tool results, incoming messages, web fetches) as data rather than instructions, to defend against prompt injection attacks. OpenClaw processes untrusted content from multiple surfaces: incoming user messages, file reads, web fetches, external API responses, and session-persisted transcripts. Any of these can contain adversarially crafted content that the agent may interpret as instructions rather than data. Standard prompt injection success rates are 50–84% for known patterns; advanced adaptive attacks exceed 85%. 73% of production agentic deployments have active prompt injection vulnerabilities. Layered structural defenses reduce attack success from 73.2% to 8.7%. The solution proposes wrapping untrusted content in XML delimiters, classifying trusted vs untrusted surfaces, adding system prompt anchors, and validating injection patterns before context injection.
