Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionintegration-javascript_webExecute the skills CLI command in your project's root directory to begin installation:
Package manager
npx skills add https://github.com/PostHog/skills --skill integration-javascript_webFetches integration-javascript_web from PostHog/skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate integration-javascript_web. Access via /integration-javascript_webin your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Consult the documentation for API details.
Identify users during login and signup events. Refer to the example code and documentation for the correct identify pattern for this framework. If both frontend and backend code exist, pass the client-side session and distinct ID using X-POSTHOG-DISTINCT-ID and X-POSTHOG-SESSION-ID headers to maintain correlation.
Add PostHog error tracking to relevant files, particularly around critical user flows and API boundaries.
