core v1.0 · 24 packages · MIT

Ship AI agents in JavaScript.Without gluing 8 libraries together.

AgentsKit gives you chat UI, runtime, tools, memory, RAG, and production guardrails in one ecosystem. Swap OpenAI for Claude, React for terminal, in-memory for vector DB. Start small, grow into the full stack, and keep your code intact.

CLI

Add and run agents in one line.

`npx agentskit add <agent>` copies the source into your project — you own the code. `--run` executes it on any provider.

Read the CLI docs
agentskit — zsh

Compose

Tools, RAG, MCP, memory, permissions.

Every agent is overridable. Wire web search, an MCP server, a retriever, memory, and a permission gate — all optional, no glue code.

const agent = createResearchAgent({
adapter,
tools: [webSearch(), ...mcpTools],
retriever: rag.retrieve,

The ecosystem

Everything you need. Nothing you don't.

Every number above is a click-through. Install what you need; the core stays under 10 KB gzipped.

Beyond the libraries

Registry↗
Ready-made agents

Copy production-ready agents into your project — research, PR review, support, and more. You own the source, zero lock-in.

Playbook↗
Best practices

The engineering standards for building agents that ship — runtime validation, quality gates, security, and evals.

AKOS↗
Production OS

The operating system for agents at scale — orchestration, egress control, and RBAC for running agents in production.

Proof, not promises

Start from a template, a demo, or a runnable recipe.

Scaffold a project, inspect a live demo, or copy a recipe and run it locally. Pick the angle you trust.

Scaffold a starter

Use `agentskit init` to spin up a React chat, Ink terminal app, runtime worker, or multi-agent starter.

Browse live examples

Open interactive demos for support bots, code assistants, RAG chat, runtime agents, and multi-agent planning.

Copy runnable recipes

Jump straight into end-to-end snippets for integrations, replay, security, evals, and retrieval pipelines.
