Prompt spaghetti is real

Managing prompts in code leads to scattered, unmaintainable strings that waste tokens and require deployments for every change.

Scattered across the codebase

Centralized prompt library

Every change = deployment

Update without redeploying

Tokens wasted on irrelevant context

75% average token reduction

Logic in strings is a nightmare

Rich operator set + conditionals

Prompts that think before they speak

Variables render at runtime

Dynamic value injection with transforms and defaults.

Conditionals filter irrelevant sections

Runtime branching based on context variables.

Modular prompt blocks

import { EchostashClient } from "@echostash/sdk"

// Initialize the client
const client = new EchostashClient({
  apiKey: process.env.ECHOSTASH_API_KEY
})

// Fetch and render a prompt
const prompt = await client.getPrompt("welcome-message")
const rendered = client.render(prompt, {
  userName: "Alice",
  language: "English"
})
