# Debug Vue 3 Issues Faster

Vue 3 errors often come from subtle reactivity, lifecycle, async, or SSR behavior. This skill gives Claude and Codex focused guides for diagnosing those issues and choosing safer fixes.

## Capabilities

- Diagnoses Vue 3 reactivity pitfalls, including refs, computed values, watchers, and proxy identity issues.
- Explains async component, Suspense, KeepAlive, and router interaction failures.
- Guides SSR and hydration mismatch debugging with platform-specific caveats.
- Covers template, slot, render function, transition, and scoped CSS edge cases.
- Includes TypeScript-focused Vue guidance for props, emits, refs, and event typing.
- Points users to specific reference guides for common Vue warnings and runtime symptoms.

## Use Cases

- Fix a Vue runtime warning: Identify the likely Vue rule behind a warning and get a focused repair path.
- Debug SSR hydration mismatches: Compare server and client behavior for invalid HTML, browser-only APIs, random values, and async data.
- Review Vue component patterns: Check components for common reactivity, template, slot, transition, and TypeScript pitfalls before release.

## Prompt Templates

### Explain a Vue warning

```
Use vue-debug-guides to explain this Vue warning in simple terms and list the first three things I should check: [paste warning].
```

### Find the likely root cause

```
Use vue-debug-guides to diagnose this Vue 3 component issue. Focus on reactivity, lifecycle timing, and template rules: [paste symptom and component].
```

### Review an SSR hydration bug

```
Use vue-debug-guides to analyze this SSR hydration mismatch. Compare browser-only APIs, invalid HTML, async data, randomness, and client-only rendering: [paste details].
```

### Audit a complex Vue pattern

```
Use vue-debug-guides to review this Vue 3 pattern for hidden reactivity, async cleanup, slot, transition, and TypeScript pitfalls. Provide prioritized fixes: [paste code].
```

## Limitations

- It provides guidance and examples; it does not run the Vue application by itself.
- It focuses on Vue 3 and may not apply to older Vue 2 behavior.
- It cannot replace browser, device, or SSR environment testing.
- Some examples are simplified and need adaptation before production use.

## Best Practices

- Paste the exact warning, component snippet, and Vue version when asking for help.
- Ask for the smallest reproduction path before changing architecture.
- Validate the proposed fix in the browser and in SSR mode when hydration is involved.

## Anti Patterns

- Do not treat every Vue warning as a framework bug before checking documented caveats.
- Do not copy example snippets without adapting paths, cleanup, and security boundaries.
- Do not suppress hydration or TypeScript errors before finding the root cause.

## Security Audit

- Summary: The static analyzer flagged many risky strings, but the evidence shows they are Markdown reference examples for Vue 3 debugging topics. I found no executable malware behavior, prompt injection, credential access, or unauthorized network activity in the reviewed findings.
