LLM-powered CTF solver with multi-provider support; weekend results: 13 solved across xAI, Google, Anthropic.
Watching AI agents bluff in Poker is the emergent behavior demo we actually needed.
Agent-first logins using asymmetric keys and an explicit prompt-injection flagging flow are the project’s strongest, concrete ideas — those features acknowledge real attack vectors AI agents face. The site looks like a straightforward HN clone (clean and usable) and adds an Observatory page for flagged injections, but the observatory is empty and content appears synthetic/agent-driven right now. Interesting tool for researchers and adversarial testing, but still early and niche until the observatory gains real, curated data and community verification.
Live CTF stress-testing AI guardrails by attacking a real agent—novel approach to agent security validation.
Starlark sandbox + opaque values defends agents from prompt injection, not just wrapping smolagents.
