gateway: Instructions file for Claude Code

CLAUDE.md

gateway CLAUDE.md is an instructions file for Claude Code from Portkey-AI/gateway. It costs 844 tokens per session, scanned A, original, MIT.

Repository instructions for Claude Code, an AI coding assistant, explaining how to develop the Portkey AI Gateway, software that sends requests to different large language model services through one system.

In plain words
What is it for?
Starting the gateway, building it, testing its main code and plugins, checking formatting, and deploying it to Cloudflare Workers or Node.js.
Why use it?
It gives the assistant the project’s commands for development, testing, formatting, building, and deployment instead of leaving those choices unclear.

About the project

Portkey AI Gateway is an open-source service that gives applications one interface for routing requests to language, vision, audio, and image models. Teams use it to connect AI applications to many model providers while handling retries, fallbacks, load balancing, and guardrails.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gateway CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This is the Portkey AI Gateway - a fast, reliable AI gateway that routes requests to 250+ LLMs with sub-1ms latency. It's built with Hono framework for TypeScript/JavaScript and can be deployed to multiple environments including Cloudflare Workers, Node.js servers, and Docker containers.

Development Commands

Core Development

  • npm run dev - Start development server using Wrangler (Cloudflare Workers)
  • npm run dev:node - Start development server using Node.js
  • npm run build - Build the project for production
  • npm run build-plugins - Build the plugin system

Testing

  • npm run test:gateway - Run tests for the main gateway code (src/)
  • npm run test:plugins - Run tests for plugins

  • npm run start:node - Start production Node.js server

Architecture

Core Components

Main Application (src/index.ts)

  • Hono-based HTTP server with middleware pipeline
  • Handles multiple AI provider integrations
  • Routes: /v1/chat/completions, /v1/completions, /v1/embeddings, etc.

Provider System (src/providers/)

  • Modular provider implementations (OpenAI, Anthropic, Azure, etc.)
  • Each provider has standardized interface: api.ts, chatComplete.ts, embed.ts
  • Provider configs define supported features and transformations

Middleware Pipeline

  • requestValidator - Validates incoming requests
  • hooks - Pre/post request hooks
  • memoryCache - Response caching
  • logger - Request/response logging
  • adminAuth - Node-only local UI session auth for /public/* login endpoints and /log/stream
  • portkey - Core Portkey-specific middleware for routing, guardrails, etc.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
