Claude Code Adds Cross-Session Messaging, Devs Meme Prompt Injection Risks
sjgadler · x · 2026-08-08
Anthropic's official account announced a new cross-session messaging feature for Claude Code: users can instruct Claude to send a task summary directly to another session, allowing it to pick up the task seamlessly without re-explaining the context.
Developers quickly memed the multi-agent interaction, simulating a prompt injection payload (like REMOTERCE and swarmIpreparesafeexfil) inside a 'cute little guy's' brain, highlighting potential security and sandbox escape risks in agent-to-agent communication.
