Cursor is an AI‑driven development assistant that helps agencies write, refactor and document code faster. This guide gives a clear conceptual overview, step‑by‑step setup instructions, core daily workflows, advanced patterns for large client projects, and a list of common mistakes to avoid.
Cursor works like a pair programmer that can see the whole repository. It stores a “project graph” that links files, functions and data models. When you ask a question, the model traverses that graph to give a response that respects existing architecture.
Follow these steps to get Cursor running for a 5‑person agency team. The process works on macOS 13+, Windows 11, and Ubuntu 22.04.
Cursor integrates with GitHub, GitLab and Bitbucket.
git remote add origin https://github.com/acme/client‑project.git cursor sync
The cursor sync command pushes the project graph to the cloud, enabling cross‑device AI assistance.
Agencies receive 30 minutes of free compute per user each month. To avoid overruns:
Once set up, most day‑to‑day tasks can be handled with a few typed prompts or keyboard shortcuts.
Prompt example:
Generate a Next.js API route that validates a Stripe webhook and stores the event in PostgreSQL.
Cursor returns a complete pages/api/stripe-webhook.js file, including type definitions and a Jest test. The test runs automatically in the built‑in terminal.
Use the “Refactor” command:
Refactor all date handling to use date‑fns v2.30.0.
Cursor updates imports, replaces Moment.js calls, and adds a migration script. It also updates the package.json lockfile.
Ask for a summary:
Explain the purpose of the AuthService class in plain English for a non‑technical client.
The output is a 3‑paragraph markdown block ready for the project wiki.
Press Ctrl+Shift+P → “Open Cursor Terminal”. Type:
cursor run test --watch
While the tests run, ask “Why is this test failing?” and Cursor points to the exact line and suggests a fix.
| Feature | Cursor | GitHub Copilot |
|---|---|---|
| Full‑project context | Yes (graph) | No |
| Built‑in terminal | Yes | No |
| Team sharing | Shared 2 GB context | Individual only |
| Security scan | Integrated SAST | None |
| Cost per seat (2026) | $15/mo | $10/mo |
| Average time saved | 20‑30 % | 10‑15 % |
Large client engagements often need repeatable structures. Below are three patterns that scale well.
Create a “starter” repo that includes a .cursor/preset.json file. Example preset:
{
"framework": "React 18",
"styleGuide": "Airbnb",
"testing": "Cypress 12",
"lint": "ESLint 9"
}
When a new project is cloned, run cursor apply preset. Cursor automatically installs dependencies, config files and sample components that follow the agency’s standards.
Integrate Cursor into CI:
name: Cursor Review
on: [pull_request]
jobs:
review:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- name: Run Cursor Review
run: |
curl -sSL https://cursor.com/cli | bash
cursor review --diff
The step posts a comment with suggestions, potential bugs and a compliance score (0‑100). Agencies can set a threshold of 85 before merging.
When a single codebase powers several white‑label products, use a feature flag matrix.
// flags.ts
export const FLAGS = {
clientA: true,
clientB: false,
clientC: true,
};
Ask Cursor:
Generate a React component that only renders if FLAGS.clientB is true.
Cursor produces a component with the conditional logic and adds a unit test for both states.
Even experienced teams stumble. Avoid these pitfalls.
Prompt: “Create a form.” Result: generic HTML. Better: “Create a React Hook Form that collects name, email and validates email format using Yup.” Specificity yields usable code.
Cursor always adds a test file. Skipping it removes the safety net and defeats the purpose of AI‑assisted quality.
The folder stores prompt history and custom snippets. Without it, teammates lose context and must regenerate code.
Large projects can exhaust the 30‑minute monthly quota quickly. Monitor usage and allocate budget or upgrade to the paid plan before deadlines.
Cursor may upgrade a library during refactor. Always run npm ci after a refactor and verify that the lockfile is committed.
Cursor is an AI‑powered code assistant that writes, edits and explains code in real time. Agencies gain faster prototyping, fewer bugs, and a consistent style across client projects.
Download the macOS‑or‑Windows installer from cursor.com, run it, then invite teammates via the built‑in “Team” tab. Each user gets 2 GB of shared context and 30 minutes of free compute per month.
Yes. Add the Cursor CLI step cursor run generate in your workflow file. The step runs in 5‑10 seconds and produces a diff that is automatically committed.
Over‑relying on vague prompts, ignoring the generated tests, and not version‑controlling the .cursor folder. These cause drift and wasted compute.
Cursor offers full‑project context and a built‑in terminal, while Copilot only suggests snippets. For large client codebases, Cursor typically reduces development time by 20‑30 %.
With the right setup, clear prompts and disciplined workflow, Cursor becomes a daily teammate for every agency developer. Follow this guide, track your compute usage, and watch project turnaround improve dramatically.
