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.

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({

tools: [webSearch(), ...mcpTools],
retriever: rag.retrieve,

The ecosystem

One core. Everything else plugs in.

Six contracts on one tiny core. Every layer is optional and swappable — click any to dive in.

@agentskit/core
< 10 KB
zero dependencies

Types, events, and six contracts. Every package plugs into this — swap any layer without touching the rest.

One foundation. A useful next step for every stage.

These are contextual handoffs, not another catalog. Start with the problem you have now; every product remains optional.

Build the agent.Skip the plumbing.

One install. First streaming agent in under 10 lines. Swap providers, UI, and memory without a rewrite. No signup, no lock-in — MIT all the way down.

Scaffold a UI binding, terminal, or runtime starter via @agentskit/cli — not product Chat. For versioned multi-surface chat apps use AgentsKit Chat (@agentskit/chat-cli) at chat.agentskit.io.
