PostHog error tracking for Svelte
What this skill does
# PostHog error tracking for Svelte This skill helps you add PostHog error tracking to Svelte applications. ## Reference files - `references/svelte.md` - Sveltekit error tracking installation - docs - `references/fingerprints.md` - Fingerprints - docs - `references/alerts.md` - Send error tracking alerts - docs - `references/monitoring.md` - Monitor and search issues - docs - `references/assigning-issues.md` - Assign issues to teammates - docs - `references/upload-source-maps.md` - Upload source maps - docs Consult the documentation for API details and framework-specific patterns. ## Key principles - **Environment variables**: Always use environment variables for PostHog keys and host URLs. Never hardcode them. - **Minimal changes**: Add error tracking alongside existing error handling. Don't replace or restructure existing error handling code. - **Autocapture first**: Enable exception autocapture in the SDK initialization before adding manual captures. - **Source maps**: Upload source maps so stack traces resolve to original source code, not minified bundles. - **Manual capture for boundaries**: Use `captureException()` at error boundaries and catch blocks for errors that don't propagate to the global handler. ## Framework guidelines - Set paths.relative to false in svelte.config.js — this is required for PostHog session replay to work correctly with SSR and is easy to miss - Use the Svelte MCP server tools to check Svelte documentation (list-sections, get-documentation) and validate components (svelte-autofixer) — always run svelte-autofixer on new or modified .svelte files before finishing

generating-lwc-components
IncludedLightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.
tanstack-query
IncludedManage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
document-processor-api
IncludedProcess documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.

tanstack-query
IncludedManage server state in React with TanStack Query v5. Covers useMutationState, simplified optimistic updates, throwOnError, network mode (offline/PWA), and infiniteQueryOptions. Use when setting up data fetching, fixing v4→v5 migration errors (object syntax, gcTime, isPending, keepPreviousData), or debugging SSR/hydration issues with streaming server components.

IncludedNext.js performance optimization and best practices. Use when writing Next.js code (App Router or Pages Router); implementing Server Components, Server Actions, or API routes; optimizing RSC serialization, data fetching, or server-side rendering; reviewing Next.js code for performance issues; fixing authentication in Server Actions; or implementing Suspense boundaries, parallel data fetching, or request deduplication.
