Installation

Install @zeroleaks/shield with your preferred package manager:

npm install @zeroleaks/shield

bun add @zeroleaks/shield

Peer Dependencies

Provider wrappers require the corresponding LLM client. All are optional; install only what you use:

Example: if you use the OpenAI wrapper only:

npm install @zeroleaks/shield openai

TypeScript

TypeScript support is included. No separate @types package is required. Types are exported from the main entry point and subpaths:

import { harden, detect, sanitize } from "@zeroleaks/shield";
import type { HardenOptions, DetectResult, SanitizeResult } from "@zeroleaks/shield";

// Provider-specific types
import { shieldOpenAI } from "@zeroleaks/shield/openai";
import type { ShieldOpenAIOptions } from "@zeroleaks/shield/openai";
