What is Cursor?
Cursor's Agent SDK turns custom agents into code projects you can test, then deploy anywhere.
Cursor has grown from an editor into a delivery platform: Projects coordinates cloud agents, Origin hosts repos with a 20+ app marketplace, Rollouts watches deploys, and the Environments API scripts agent sandboxes. On October 20 the Agent SDK went GA. An agent is now a folder with a prompt, typed tools, skills, MCP connections and channels, tested with evals and deployed either to Cursor or to the team's own infrastructure.
What is KubeArmor?
KubeArmor is hardening its eBPF DNS visibility and supply chain security posture in the v1.7.5 pre-release cycle.
KubeArmor is in active pre-release for v1.7.5, having shipped three release candidates. The rc1 switched the BPF hook for DNS traffic from udp_sendmsg to udp_send_skb — a kernel-level change that captures DNS at the correct interception point for accurate visibility. The rc2 added SLSA Level 3 provenance, isolated container builds, and improved OpenSSF Scorecard compliance to the project's build and release pipeline. Support for Ubuntu 26.04, openEuler 24.03 LTS-SP3, and kernel 6.17 DNS tracking arrived in the 1.7.4-rc3 cycle.

Cursor
7.5INFRA · APIS
Cursor's Agent SDK turns custom agents into code projects you can test, then deploy anywhere.
◆ Current state
Cursor has grown from an editor into a delivery platform: Projects coordinates cloud agents, Origin hosts repos with a 20+ app marketplace, Rollouts watches deploys, and the Environments API scripts agent sandboxes. On October 20 the Agent SDK went GA. An agent is now a folder with a prompt, typed tools, skills, MCP connections and channels, tested with evals and deployed either to Cursor or to the team's own infrastructure.
◆ Where it's heading
The last month has been about opening Cursor's agent stack to outside code: partner apps write into Origin, the Environments API exposes sandboxes, and the Agent SDK lets teams build their own bots on the same runtime. Agents that wake on PR, CI, Slack, webhook and cron events push Cursor past the IDE into always-on team automation. Cursor is selling the agent runtime itself, not just its own agents.
◆ Prediction
Expect more starter templates and SDK-built agents to appear in the app marketplace, and tighter links between SDK agents and Projects or Rollouts. Whether self-hosted deploys get the same dashboard tooling as Cursor-hosted ones is not yet clear from the entries.
KubeArmor
5.0INFRA · APIS
KubeArmor is hardening its eBPF DNS visibility and supply chain security posture in the v1.7.5 pre-release cycle.
◆ Current state
KubeArmor is in active pre-release for v1.7.5, having shipped three release candidates. The rc1 switched the BPF hook for DNS traffic from udp_sendmsg to udp_send_skb — a kernel-level change that captures DNS at the correct interception point for accurate visibility. The rc2 added SLSA Level 3 provenance, isolated container builds, and improved OpenSSF Scorecard compliance to the project's build and release pipeline. Support for Ubuntu 26.04, openEuler 24.03 LTS-SP3, and kernel 6.17 DNS tracking arrived in the 1.7.4-rc3 cycle.
◆ Where it's heading
KubeArmor is running two parallel improvement tracks: eBPF policy enforcement quality (BPF hook changes, quota handling via NPE, hostname/TLD matching improvements) and supply chain security compliance (SLSA, Scorecard, pinned dependencies, isolated builds). The latter is increasingly a table-stakes requirement for enterprise Kubernetes security teams auditing their toolchain, not a differentiator. New kernel and OS support signals broadening the deployment surface — particularly for regulated environments with specific OS requirements.
◆ Prediction
v1.7.5 stable will ship shortly given three RCs already published. The eBPF DNS visibility change enables syscall-level DNS auditing for workloads that need it; the SLSA Level 3 provenance will be cited in enterprise security reviews as a prerequisite for adoption.
