Why it matters
The 'harness-centric' framing reframes how defenders should assess agentic-AI offensive capability, shifting focus from model benchmarks to the tool/permission scaffolding that actually enables autonomous exploitation.
An opinion/analysis piece argues that in 2026 the decisive factor in offensive AI is not the underlying model but the 'harness' — the scaffolding of tools, sandboxed execution, planning loops, memory, and permissions that turns an LLM into an autonomous agent capable of chaining exploit steps end-to-end. The author cites academic work showing LLM agents can autonomously exploit one-day vulnerabilities and references reported autonomous AI cyberattack campaigns.
