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 Snort 3?

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

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.

Snort 3's release train is almost entirely appid: identifying traffic it can no longer read.

◆ Current state

Every release in this window is dominated by two threads. The first is appid, the application identification engine, which keeps gaining ways to classify traffic that encryption has closed off: a QUIC extractor, preferring QUIC appid over SSL, midstream service discovery, SSL detection during midstream, and a fix for detection when the SNI is spoofed. The second is a sustained memory-safety campaign across dce_rpc, dce_smb, and appid, with use-after-frees, leaks, underflows, and out-of-bounds reads closed release after release.

◆ Where it's heading

Snort is adapting an inspection engine built for readable traffic to a network where most of it is not. The investment is in inferring application identity from what remains visible, and in doing so on flows the sensor joined late. Alongside that, output is becoming more machine-consumable, with appid in alert_json, binary flow state dumps, and new DNS counters. The C codebase is being hardened continuously, which suggests fuzzing and sanitizer work running behind the feature stream.

◆ Prediction

QUIC handling has moved from an extractor to an appid preference in consecutive releases while midstream detection keeps widening; extending the same treatment to more encrypted protocols is the clearest continuation these entries support.
