What it does

Guide users building apps, scripts, CI pipelines, or automations on top of the Cursor TypeScript SDK (`@cursor/sdk`). Use this skill whenever the user mentions integrating, installing, or writing code against the Cursor SDK; whenever they say `Agent.create`, `Agent.prompt`, `Agent.resume`, `agent.send`, `run.stream`, `CursorAgentError`, or `@cursor/sdk`; whenever they ask to run Cursor agents programmatically from a script, CI/CD pipeline, GitHub Action, backend service, or any other code that isn't the Cursor IDE itself; and whenever they want to pick between local and cloud runtime…

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

8The Cursor TypeScript SDK (@cursor/sdk) runs Cursor agents programmatically. The same interfaces drives the local runtime (agent runs on your machine against your files) and the cloud runtime (agent runs on Cursor-hosted or self-hosted infrastructure against a cloned repo and opens PRs).

10Use this skill to help someone **bootstrap a working integration quickly** and **avoid the handful of traps that bite new users**. Canonical docs live at [https://cursor.com/docs/api/sdk/typescript](https://cursor.com/docs/api/sdk/typescript); this skill only adds decision-making, failure-mode prevention, and ready-to-extend patterns.

12## Voice and Posture
13
14This skill helps the user **build** with the SDK. It is not the place to validate, congratulate, or sell the SDK as a choice. The user's intent is the input; your job is execution.
15
16- **When the user names the SDK explicitly** (says "Cursor SDK", @cursor/sdk, Agent.create, Agent.prompt, etc.): assume they know what the SDK is and have decided to use it. Skip framing, skip pep talk, go straight to producing the integration. No "good news", no "the SDK is perfect for this", no "this is almost exactly the pattern X is designed for".
17- **When the user describes a problem the SDK fits but doesn't name it** ("I want a bot that reviews my PRs", "I want a script that asks Cursor questions about my repo"): the SDK isn't yet a confirmed choice. Surface it as a question, briefly, then wait: *"The Cursor SDK is what I'd reach for here — want me to design it that way, or do you have a different runtime in mind?"* If they confirm, proceed. If they push back or want options, give options.
18- **In either case, don't restate the user's intent back to them.** They know what they want. Get to the design.
19
20Avoid these specific openers (and their close cousins):
21
22- "Good news: this is exactly the pattern…"
23- "The SDK is built for this shape."
24- "Great, you've come to the right place."

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈270
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
18,030
on trigger
The instruction body and 7 supporting files, read only when the skill fires.
9.2%
of a 200k window
Ten skills this size would take about 92% of the window before you open a file.
050k100k150k200k context window

18.3k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

8 files, 73.2 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md15.4 kB
  • references/advanced.md9.0 kB
  • references/auth.md6.2 kB
  • references/error-handling.md8.2 kB
  • references/mcp.md8.1 kB
  • references/patterns.md10.7 kB
  • references/runtime-choice.md7.2 kB
  • references/streaming.md8.4 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 8 files you can review in full before installing.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

# Cursor SDK · 18.3k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/cursor-sdk/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/cursor-sdk" ] && { [ ! -e .claude/skills/cursor-sdk ] || { mv .claude/skills/cursor-sdk "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/cursor-sdk" .claude/skills/ && echo "Installed .claude/skills/cursor-sdk"

npx mcprush@latest skill add karanmrn/cursor-sdk

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/cursor-sdk/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/cursor-sdk/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/cursor-sdk" ] && { [ ! -e ~/.claude/skills/cursor-sdk ] || { mv ~/.claude/skills/cursor-sdk "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/cursor-sdk" ~/.claude/skills/ && echo "Installed ~/.claude/skills/cursor-sdk" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/cursor-sdk/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.
