Understand the editor shell before shopping extensions.

This layer is Cursor's center of gravity: the homepage, docs, marketplace, CLI, and cloud-agent surfaces that define what the product thinks it is.

Layer thesis

How to read this branch of the ecosystem

This is the shortest explanation of what this layer is for and why it matters.

Cursor's own surfaces frame the whole ecosystem as an editor becoming an agent shell, so this is the fastest place to establish the mental model.

Work patterns

What people actually do here

These workflow slices connect the layer to real usage patterns.

Workflow pattern

Treat cloud, CLI, and model routing as escalation layers

Remote agents, command-line flows, and provider-routing tools matter strategically, but they are usually the second move after understanding the editor and conventions layer first.

Guardrails

What to remember while exploring

Layer-specific best-practice reminders that keep this branch legible.

Best practice

Read the official docs and marketplace as the product model, not just the feature list

The official surfaces repeatedly frame Cursor as an editor-plus-agent shell. That broader framing is what makes the ecosystem's rules, skills, plugins, MCP, and runtime branches coherent.
