# sentry-svelte-sdk

A skill that walks your agent through full Sentry setup in Svelte and SvelteKit: it scans the project, proposes a feature set and writes the config files.

## What it does

The skill starts by reading your project. It checks `package.json` for `@sveltejs/kit` and `@sentry/sveltekit`, looks for `svelte.config.js` and `vite.config.ts`, and inspects `src/hooks.client.ts` and `src/hooks.server.ts`. The SvelteKit version decides the setup path: on 2.31.0 and newer, server init moves to `src/instrumentation.server.ts`; on older versions it stays in `hooks.server.ts`. Plain Svelte without SvelteKit gets `@sentry/svelte` instead.

Then it leads with a proposal rather than open questions: error monitoring, tracing and session replay, with logging via `Sentry.logger.*` added when the app already logs on the server through something like `pino` or `winston`. The manual route is spelled out step by step — install the package, edit `svelte.config.js` to enable `experimental.instrumentation` and `tracing`, then initialize the client and server sides.

There is a second route: the wizard, `npx @sentry/wizard@latest -i sveltekit`. You have to run that one yourself in a terminal, because it opens a browser for login and needs interactive input an agent cannot handle. It installs the SDK, wires the hooks, configures the Vite plugin and uploads source maps. The sample configs use `tracesSampleRate` of 1.0 and a comment advises dropping to 0.1–0.2 in production, so check that value before you ship.

## Requirements
- Works with: Sentry

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/sentry-for-ai --skill sentry-svelte-sdk -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/sentry-svelte-sdk/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sentry-svelte-sdk/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/sentry-for-ai --skill sentry-svelte-sdk -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/sentry-svelte-sdk/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/sentry-for-ai --skill sentry-svelte-sdk -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/sentry-svelte-sdk/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install getsentry/sentry-for-ai sentry-svelte-sdk
```

2. **Manually: put the files in place**
- File: `.github/skills/sentry-svelte-sdk/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/sentry-for-ai --skill sentry-svelte-sdk -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/getsentry/sentry-for-ai --path skills-legacy/sentry-svelte-sdk
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sentry-svelte-sdk/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add getsentry/sentry-for-ai --skill sentry-svelte-sdk -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/getsentry/sentry-for-ai/tree/HEAD/skills-legacy/sentry-svelte-sdk/SKILL.md

## When to use it
- wire error monitoring into a SvelteKit app
- set up tracing for client navigation and server requests
- turn on session replay with text and media masking
- correlate server logs with traces through `Sentry.logger.*`
- pick the right init pattern for your SvelteKit version

## Example prompts
- add Sentry to my SvelteKit project
- set up @sentry/sveltekit with tracing and session replay
- check what @sentry packages I already have and suggest the rest

# Sentry Svelte SDK

Opinionated wizard that scans your project and guides you through complete Sentry setup for Svelte and SvelteKit.

## Invoke This Skill When

- User asks to "add Sentry to Svelte" or "set up Sentry" in a Svelte/SvelteKit app
- User wants error monitoring, tracing, session replay, or logging in Svelte or SvelteKit
- User mentions `@sentry/svelte`, `@sentry/sveltekit`, or Sentry SDK for Svelte

> **Note:** SDK versions and APIs below reflect current Sentry docs at time of writing (`@sentry/sveltekit` ≥10.8.0, SvelteKit ≥2.31.0).
> Always verify against [docs.sentry.io/platforms/javascript/guides/sveltekit/](https://docs.sentry.io/platforms/javascript/guides/sveltekit/) before implementing.

## Phase 1: Detect

Run these commands to understand the project before making any recommendations:

```bash
# Detect framework type
cat package.json | grep -E '"svelte"|"@sveltejs/kit"|"@sentry/svelte"|"@sentry/sveltekit"'

# Check for SvelteKit indicators
ls svelte.config.js svelte.config.ts vite.config.ts vite.config.js 2>/dev/null

# Check SvelteKit version (determines which setup pattern to use)
cat package.json | grep '"@sveltejs/kit"'

# Check if Sentry is already installed
cat package.json | grep '"@sentry/'

# Check existing hook files
ls src/hooks.client.ts src/hooks.client.js src/hooks.server.ts src/hooks.server.js \
   src/instrumentation.server.ts 2>/dev/null

# Detect logging libraries (Node side)
cat package.json | grep -E '"pino"|"winston"|"consola"'

# Detect if there's a backend (Go, Python, Ruby, etc.) in adjacent directories
ls ../backend ../server ../api 2>/dev/null
cat ../go.mod ../requirements.txt ../Gemfile 2>/dev/null | head -3
```
