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 FOSSA CLI?

fossa-cli's releases are ecosystem-by-ecosystem repairs to how lockfiles are read.

Releases arrive every one to three weeks and almost all of the substance is per-ecosystem dependency resolution. In this window: Node workspaces declared with a leading ./ now match, npm v3 lockfiles get target-level dependency scoping, pnpm lockfile handling was refactored, and sbt 1.4+ projects with an explicit DependencyTreePlugin route to the built-in command. Around that sit operational adjustments — the default scan timeout raised from 30 seconds to a minute, release-group project resolution moved to a server-side lookup — and two tags that carry nothing but a Themis version bump or a release cut.

Cursor vs FOSSA CLI: editorial side-by-side

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.

fossa-cli's releases are ecosystem-by-ecosystem repairs to how lockfiles are read.

◆ Current state

Releases arrive every one to three weeks and almost all of the substance is per-ecosystem dependency resolution. In this window: Node workspaces declared with a leading ./ now match, npm v3 lockfiles get target-level dependency scoping, pnpm lockfile handling was refactored, and sbt 1.4+ projects with an explicit DependencyTreePlugin route to the built-in command. Around that sit operational adjustments — the default scan timeout raised from 30 seconds to a minute, release-group project resolution moved to a server-side lookup — and two tags that carry nothing but a Themis version bump or a release cut.

◆ Where it's heading

The work is breadth-of-accuracy, not new features: every release closes a case where a real project layout produced an incomplete or wrong dependency graph. That is the correct shape for a compliance scanner, where a missed transitive dependency is a failed audit rather than a rough edge. The steady stream of package-manager-specific fixes suggests coverage is still being driven by customer projects that scan badly, which means the tail of ecosystems is long and being worked through one at a time.

◆ Prediction

Expect the pattern to continue with another package manager's lockfile format — the timeout increase hints scans are also getting slower on large monorepos, so performance work on the same paths is likely next.
