@reactive-agents/prompts

Prompt management for the Reactive Agents framework.

A template engine with variable interpolation and a built-in library of agent prompts for common use cases.

Installation

bun add @reactive-agents/prompts

Features

• Template engine — {{variable}} interpolation with type-safe bindings
• Prompt library — pre-built system prompts for researcher, coder, analyst, and more
• Versioning — store and retrieve prompt versions

Usage

import { PromptTemplate, PromptLibrary } from "@reactive-agents/prompts";

// Use a built-in prompt
const systemPrompt = PromptLibrary.get("researcher");

// Or define your own
const template = PromptTemplate.create({
  template: "You are a {{role}} expert. Answer in {{language}}.",
  variables: { role: "TypeScript", language: "English" },
});

const prompt = template.render({ role: "React", language: "Spanish" });

With the builder:

import { ReactiveAgents } from "reactive-agents";

// Enable built-in prompt templates (reasoning, evaluation, agent)
const agent = await ReactiveAgents.create()
  .withName("researcher")
  .withProvider("anthropic")
  .withPrompts() // registers all built-in templates
  .build();

// Or register custom templates at build time:
const customAgent = await ReactiveAgents.create()
  .withName("custom")
  .withProvider("anthropic")
  .withPrompts({
    templates: [
      {
        id: "custom.system",
        name: "Custom System Prompt",
        version: 1,
        template: "You are a {{role}} expert. Answer in {{language}}.",
        variables: [
          { name: "role", required: true, type: "string" },
          {
            name: "language",
            required: false,
            type: "string",
            defaultValue: "English",
          },
        ],
      },
    ],
  })
  .build();
