The harness is the product, not the model

Cloudflare’s Project Glasswing write-up landed today and the Hacker News thread is mostly arguing about whether the prose was written by Mythos or by Opus. It is a fair complaint and an irrelevant one. The diagram halfway down the page is the actual deliverable, and almost nobody is talking about it. Cloudflare has published the reference architecture for doing vulnerability research with a frontier model at scale. The model in the headline is the easy part. The seven-stage agent pipeline around it is what makes the model useful, and it is the bit worth stealing. What the pipeline actually does Recon reads the repository top-down and produces a shared architecture document covering build commands, trust boundaries, entry points, and likely attack surface. Every downstream agent works from the same map. Hunt fires roughly fifty agents in parallel, each pinned to one attack class against one narrow scope. Each hunter can compile and execute proof-of-concept code in a per-task scratch…
