What is Cursor?
Cursor is industrializing cloud agents — routed models, prebuilt environments, every surface.
Cursor's last two months are almost entirely about cloud agents rather than the editor. Agents now launch from iOS, iPad, and Slack, run in isolated VMs, and boot from environments Cursor rebuilds in the background. Auto mode became Cursor Router, which dispatches each request to a frontier or price-efficient model and bills at the routed model's rate. Team plumbing matured alongside it: marketplaces, Team MCPs, plugins, and automations.
What is watcher?
watcher is a thin filesystem-events binding whose releases are mostly build work.
The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.

Cursor

Cursor is industrializing cloud agents — routed models, prebuilt environments, every surface.
◆ Current state
Cursor's last two months are almost entirely about cloud agents rather than the editor. Agents now launch from iOS, iPad, and Slack, run in isolated VMs, and boot from environments Cursor rebuilds in the background. Auto mode became Cursor Router, which dispatches each request to a frontier or price-efficient model and bills at the routed model's rate. Team plumbing matured alongside it: marketplaces, Team MCPs, plugins, and automations.
◆ Where it's heading
The direction is making the agent rather than the editor the unit of work, then removing every source of latency and friction around it. Environment setup went from a manual step to a reusable snapshot to a continuously rebuilt warm pool; model selection went from a picker to a router with admin controls; surfaces went from desktop to phone, tablet, and chat. Nearly every release pairs the user-facing feature with an admin or team control, which points at enterprise buyers as the audience being served.
◆ Prediction
The next moves most likely target cloud agent throughput and spend controls — finer routing or more environment reuse — rather than another client surface, since mobile and Slack have each had two releases already and the newest work concentrates on what happens before an agent's first token.
watcher
0.0INFRA · APIS
watcher is a thin filesystem-events binding whose releases are mostly build work.
◆ Current state
The package wraps libfswatch in an R6 Watcher class for monitoring files and directories. Seven releases over sixteen months have added a vector path argument and two accessor methods, and spent the rest of their effort on build portability — non-standard system library locations, Windows bi-arch source builds on old rtools, and most recently removing the cmake requirement so the bundled source compiles with the R toolchain alone.
◆ Where it's heading
The API is deliberately small and appears finished; the work that remains is making the C dependency install cleanly everywhere. Dropping cmake follows the same move nanonext made, which is not a coincidence — both come from the same author and both are aiming at environments where installing a build system is not an option.
◆ Prediction
With cmake gone and the bundled library current, further releases are most likely to track libfswatch upstream rather than extend the R interface.
