Description

This plugin provides Security rules for Vercel AI SDK usage (prompt injection, data handling).

Philosophy

Interlace fosters strength through integration. Instead of stacking isolated rules, we interlace security directly into your workflow to create a resilient fabric of code. We believe tools should guide rather than gatekeep, providing educational feedback that strengthens the developer with every interaction.

⚙️ Configuration Presets

| Preset | Description | | :------------ | :--------------------------------------- | | recommended | Balanced security (7 errors, 7 warnings) | | strict | Maximum security (17 errors, 2 warnings) | | minimal | Minimal config |

📚 Supported Libraries

| Library | npm | Downloads | Detection | | -------------------- | ------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------- | ------------------------------ | | ai (Vercel AI SDK) | | | Prompt Injection, Data Leakage |

🤖 AI-Agent Optimized Messages

All rule messages follow a structured format optimized for AI coding assistants:

🔒 CWE-74 OWASP:A03-Injection CVSS:9 | Unsafe Prompt | CRITICAL [SOC2,GDPR]
   Fix: Validate input before use | https://owasp.org/...

By providing this structured context (CWE, OWASP, Fix), we enable AI tools to reason about the security flaw rather than hallucinating. This allows Copilot/Cursor to suggest the exact correct fix immediately.

🔧 Supported AI SDK Functions

| Function | Full Coverage | | ---------------------- | ------------------------------ | | generateText | ✅ All 19 rules | | streamText | ✅ All 19 rules + abort signal | | generateObject | ✅ All 19 rules | | streamObject | ✅ All 19 rules + abort signal | | tool() helper | ✅ Schema validation | | embed() / embeddings | ✅ Embedding validation |

📊 Test Coverage

| Metric | Coverage | | ------------- | -------- | | Rules | 19 | | Tests | 200 | | Lines | 98%+ | | Functions | 100% |

🙋 FAQ

What's the difference between this and generic AI security linters?

Generic linters guess at patterns. This plugin knows the exact Vercel AI SDK API.

Does this work with ESLint 9 Flat Config?

Yes! Designed specifically for ESLint Flat Config — works on ESLint 8 (with flat config), 9, and 10. See the ESLint Version Support Policy for the full matrix.

How do I suppress a rule for a specific line?

// eslint-disable-next-line vercel-ai-security/require-validated-prompt
await generateText({ prompt: internalPrompt });

Why is ASI06 (Memory Corruption) not covered?

TypeScript/JavaScript are memory-safe languages. Memory corruption vulnerabilities (buffer overflows, use-after-free, etc.) are not possible in these environments.

📦 Compatibility

| Package | Version | | -------------------- | --------------------------------------------------------------------------------------------------------- | | ai (Vercel AI SDK) | | | ESLint | | | Node.js | |
