What it does

Adding Analytics is an agent skill from spencerpauly/awesome-cursor-skills. Add PostHog analytics to a web application, including event tracking, page views, feature flags, and session replay.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Product analytics. It works with PostHog, npm and Next.js. The repository describes itself as: A curated list of awesome skills for Cursor. The licence is CC0-1.0.

When your agent uses it

  • Tasks that involve Product analytics

Example prompts

  • “/adding-analytics”

Requirements

  • Python 3
  • Node.js
  • A credential in NEXT_PUBLIC_POSTHOG_KEY

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Detect the framework — check for next.config.*, vite.config.*, package.json scripts, or index.html to determine if this is Next.js, React…
  2. Install the SDK
  3. Create a provider / init module
  4. Add page-view tracking — for SPAs, create a component that calls posthog.capture('$pageview') on route change using the framework's router…
  5. Add .env variables — prompt the user for their PostHog project API key and host
  6. Add custom events — if the user specifies events to track (e.g. sign-up, purchase), add posthog.capture("event_name", { ...properties })…
  7. Feature flags (optional) — if requested, show how to use posthog.isFeatureEnabled("flag-name") or the useFeatureFlagEnabled hook.
  8. Session replay (optional) — enable by adding session_recording: { maskAllInputs: false } to the init config if requested.

What it can do on your machine

Read from SKILL.md and the folder at commit 99cd265. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm
    • pip

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • us.i.posthog.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • NEXT_PUBLIC_POSTHOG_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Adding Analytics loads about 670 tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 272 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~33
When it runs · the whole SKILL.md, loaded when a task matches
~670

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:48
    5. **Add `.env` variables** — prompt the user for their PostHog project API key and host:

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Add PostHog analytics to a web application, including event tracking, page views, feature flags, and session replay.

Add Analytics (PostHog)

Use this skill when the user asks to add analytics, event tracking, page views, feature flags, or session replay to a web application.

Steps

  1. Detect the framework — check for next.config.*, vite.config.*, package.json scripts, or index.html to determine if this is Next.js, React (Vite/CRA), Vue, Svelte, or plain HTML.

  2. Install the SDK

    • Next.js / React: npm install posthog-js
    • Next.js (server-side): npm install posthog-js posthog-node
    • Python: pip install posthog
    • Node.js backend: npm install posthog-node

  3. Create a provider / init module

    • For Next.js App Router, create app/providers.tsx:

      tsx
      "use client";
import posthog from "posthog-js";
import { PostHogProvider as PHProvider } from "posthog-js/react";
import { useEffect } from "react";

export function PostHogProvider({ children }: { children: React.ReactNode }) {
  useEffect(() => {
    posthog.init(process.env.NEXT_PUBLIC_POSTHOG_KEY!, {
      api_host: process.env.NEXT_PUBLIC_POSTHOG_HOST ?? "https://us.i.posthog.com",
      capture_pageview: false, // we capture manually for SPAs
    });
  }, []);
  return <PHProvider client={posthog}>{children}</PHProvider>;
}

    • Wrap {children} in the root layout with <PostHogProvider>.

    • For Pages Router, init in _app.tsx inside a useEffect.

  4. Add page-view tracking — for SPAs, create a component that calls posthog.capture('$pageview') on route change using the framework's router events.

  5. Add .env variables — prompt the user for their PostHog project API key and host:

    NEXT_PUBLIC_POSTHOG_KEY=phc_...
NEXT_PUBLIC_POSTHOG_HOST=https://us.i.posthog.com

    Add these keys to .env.example as well.

  6. Add custom events — if the user specifies events to track (e.g. sign-up, purchase), add posthog.capture("event_name", { ...properties }) calls in the relevant handlers.

  7. Feature flags (optional) — if requested, show how to use posthog.isFeatureEnabled("flag-name") or the useFeatureFlagEnabled hook.

  8. Session replay (optional) — enable by adding session_recording: { maskAllInputs: false } to the init config if requested.

Notes

  • Never hardcode API keys — always use environment variables.
  • Add posthog-js to the Content Security Policy if the project has one.
  • For monorepos, install in the package that renders the UI, not the root.
