@pivanov/claude-wire

Run Claude Code programmatically

Typed SDK for spawning, streaming, and controlling the CLI. Zero dependencies.

Simple API

claude.ask() returns a typed result. claude.stream() yields events via AsyncIterable. That's it.

claude.askJson(prompt, schema) returns validated, typed data. Zod, Valibot, ArkType via Standard Schema -- or raw JSON Schema.

Allow, block, or intercept any tool at runtime. Approve, deny, or mock responses.

Keep a process alive across prompts. Conversation context preserved between calls.

File access, git, shell commands, sub-agents. Everything Claude Code can do, from your code.

Discriminated union events. Typed options and results. Full IntelliSense in your editor.

npx @pivanov/claude-wire ask-json -- schema-validated JSON from the shell. Perfect for CI pipes, one-off extraction, and automation.
