About Implit – Catch fake AI-generated dependencies
Implit is an open-source CLI tool that scans AI-generated code to validate every import before execution. It checks external npm packages against the npm registry, detects typos with fuzzy matching, validates local import paths against actual file exports, and recognizes Node.js built-in modules. Designed to prevent broken builds and supply chain attacks caused by hallucinated dependencies, Implit works with zero configuration and outputs results in under a second.
Key Features
npm package verification against registry.npmjs.org with fuzzy matching
Local import validation scanning actual exports in project files
Node.js built-in module detection (e.g., fs, path, http)
Smart caching of npm lookups for 24 hours to reduce network overhead
Zero configuration – works out of the box with npx
AI-friendly --fix flag generates ready-to-paste prompts for AI tools
Pros & Cons
Pros
- Extremely fast – scans files in approximately 0.3 seconds
- Zero configuration required – just npx and go
- Detects typos with 'Did you mean?' suggestions
- Prevents security risks from fake or malicious packages
- Generates fix prompts that can be fed back to AI assistants
Cons
- Only checks static imports, not dynamic requires or runtime behavior
- Currently limited to the npm registry and Node.js ecosystem
- Network lookup required for uncached npm packages, though mitigated by 24-hour caching

FAQ
What is Implit?
Implit is a CLI tool that validates imports in AI-generated code to catch fake dependencies, typos, and invalid local paths before running the code.
How fast is Implit?
According to the project, Implit can scan a file and catch hallucinated imports in about 0.3 seconds.
Does Implit require configuration?
No, Implit works out of the box with zero configuration. You can use it with npx @neurall.build/implit check <file> or install it globally.
Can Implit fix the invalid imports automatically?
No, but the --fix flag generates a ready-to-paste prompt with details about each invalid import, which can be fed back to AI tools like Claude, GPT, or Gemini to regenerate correct code.
