Agent-Security Category Explodes: 15+ New Runtime-Governance Repos (Armorer, AgentWard, agent-aegis, immunity-agent, Adrian, vigils) Appear in a Single Week
A single week of GitHub trending surfaced more than fifteen brand-new repos all targeting agent runtime security and governance: ArmorerLabs/Armorer (control plane with sandboxes, approvals, guardrails), antgroup/agent-aegis (full-lifecycle protection for OpenClaw), PrismorSec/immunity-agent (skill governance + secret protection), secureagentics/Adrian (real-time malicious tool-use detection), and duncatzat/vigils (local Rust/Tauri approval plane). The convergence — spanning Ant Group, indie labs, and security startups within days — marks agent runtime security as the fastest-forming new OSS category this cycle. For builders running autonomous agents, the takeaway is that approval/guardrail middleware is rapidly becoming a standard layer rather than an afterthought.
