@jsonfirst/implants

One line of code to make any LLM structured, reliable, and hallucination-resistant — works with ChatGPT, Claude, Gemini, Llama and Mistral.

Install

npm install @jsonfirst/implants

Usage

const implants = require('@jsonfirst/implants');

// List available implants
implants.list();
// → ['universal', 'chatgpt', 'claude', 'gemini', 'llama', 'mistral']

// Get raw JSON string (to paste into your LLM)
implants.get('universal');

// Get as parsed object
implants.getJSON('claude');

// Get all implants
implants.getAll();

What it activates

• Anti-hallucination — zero invented names, prices, IDs or metrics
• Structured prose — no imposed JSON output, no filler openers
• Risk guard — blocks delete/deploy/transfer until explicit confirmation
• Mode confirmation — LLM confirms JSONFIRST_MODE Activé at startup
