Project Glasswing: what Mythos showed us
Cloudflare details running Anthropic's security-focused Mythos Preview LLM against 50+ of its own repos, covering how multi-agent harnesses — with parallel hunters, adversarial validators, and cross-repo tracers — dramatically improve vulnerability discovery over generic coding agents.

- Agentic workflows
Systems where AI agents execute multi-step tasks autonomously, raising interconnected questions about harness architecture, state management, reliability engineering, human oversight, and the organizational context those agents operate within.
- AI safety
AI safety spans containment of agentic systems, epistemic harms from sycophancy, skill atrophy from unreviewed code generation, and macro-level risks from rapid capability growth — each requiring different mitigations.
- LLM Agents
LLM agents are software systems that pair a language model with tools, memory, and control flow to accomplish multi-step tasks autonomously; the emerging consensus is that reliability requires engineering constraints, not better prompts.
- Multi-agent systems
Multi-agent systems coordinate multiple LLM-backed agents to handle tasks too large or complex for a single context window, but empirical research shows failure rates of 41–87% in production, making coordination structure and verification as important as raw model capability.
- Software architecture
Software architecture shapes how systems behave under pressure, how teams reason about codebases, and how much complexity accumulates over time — spanning module design, state management, deployment topology, and the feedback loops that keep all three honest.
