Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00178 | $0.03125 |
| Opus 5 | $0.00089 | $0.01563 |
| Sonnet 5 | $0.00036 | $0.00625 |
| Haiku 4.5 | $0.00018 | $0.00313 |
Grade A, and why
sdk scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cursor SDK
The Cursor TypeScript SDK (@cursor/sdk) runs Cursor agents programmatically. The same interface 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).
Use this skill to help someone bootstrap a working integration quickly and avoid the traps that bite new users. Canonical docs live at https://cursor.com/docs/api/sdk/typescript; this skill adds decision-making, failure-mode prevention, and ready-to-extend patterns.
Voice and Posture
This 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.
- 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". - 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.
- In either case, don't restate the user's intent back to them. They know what they want. Get to the design.
Avoid these specific openers (and their close cousins):
- "Good news: this is exactly the pattern..."
- "The SDK is built for this shape."
- "Great, you've come to the right place."
- "This is almost exactly the X the SDK is designed for."
- Any lede that compliments the user's choice or restates their goal in flattering terms.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sdk is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (27 stars, last pushed yesterday), licensed MIT. It adds 178 tokens to every session and 3,125 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

add-export
Add a new subpath export to the @cyanheads/mcp-ts-core package. Use when creating a new public API surface that consumers import from a dedicated subpath (e.g., @cyanheads/mcp-ts-core/newutil).
fluent-development
This skill should be used when the user asks to "build a fluent app", "create a servicenow app in typescript", or mentions "servicenow sdk", "now-sdk", "fluent", "scoped app as code", or "pro-code development" — or when the working directory contains a now.config.json or .now.ts files.
kernelcad-authoring
Author or modify kernelCAD models in TypeScript. Scripts live in .kcad.ts files; the kernelCAD CLI (kernelcad evaluate and kernelcad export stl|step|dxf|3mf|glb -o ) executes them via an OpenCASCADE WASM kernel.

Migrate a project from @waniwani/sdk 0.16.x to 0.17.0 and auto-apply its breaking change: useWaniwani() from @waniwani/sdk/mcp/react no longer auto-discovers its config from a WidgetProvider context or by opening its own host connection, so a bare useWaniwani() in a widget silently stops tracking.
