@vctools/llm

Anthropic Claude client used by the vctools suite. A thin wrapper around @anthropic-ai/sdk that returns JSON-shaped responses via tool_use.

import { LlmClient } from "@vctools/llm";

const client = new LlmClient({ model: "claude-haiku-4-5-20251001" });
const result = await client.callStructured<{ summary: string }>({
  systemPrompt: "Summarise the input in one sentence.",
  userPrompt: "...",
  toolName: "summarise",
  toolDescription: "Return a one-sentence summary.",
  schema: {
    type: "object",
    properties: { summary: { type: "string" } },
    required: ["summary"],
  },
});

Reads ANTHROPIC_API_KEY from the environment by default. Throws MissingApiKeyError if absent.
