@veyorhq/anthropic

@veyorhq/anthropic provides Anthropic-backed implementations for Veyor actors.

It exposes two separate adapters:

• @veyorhq/anthropic/anthropic creates an Effect AI model layer for @veyorhq/ai-effect.
• @veyorhq/anthropic/claude runs a Veyor actor through the local Claude Code CLI in headless mode.

[!IMPORTANT] This package is under active development. It is private, remains at 0.0.0, and is not published to a package registry.

Anthropic API

Use anthropic(model) with agent(...) when the actor should call the Anthropic API through Effect AI.

import { agent } from "@veyorhq/ai-effect";
import { anthropic } from "@veyorhq/anthropic/anthropic";
import { Writer } from "./actors.js";

const WriterImpl = agent(Writer, anthropic("claude-opus-5"), {
  prompt: "Return a concise implementation plan.",
});

The adapter reads ANTHROPIC_API_KEY through Effect Config. Missing or invalid configuration fails when the model layer is used.

Claude Code CLI

Use claude(actor, model, options) when a Claude Code session should implement the actor. The adapter drives the CLI's supported headless mode (claude --print) with your own local authentication, passes the actor's output contract via --json-schema, and validates the structured result.

import { claude } from "@veyorhq/anthropic/claude";
import { Reviewer } from "./actors.js";

const ReviewerImpl = claude(Reviewer, "claude-opus-5", {
  effort: "high",
  cwd: process.cwd(),
  permissionMode: "dontAsk",
  instructions: "Review the assignment against its acceptance criteria.",
});

Options map onto CLI flags: effort, instructions (--append-system-prompt), permissionMode, allowedTools/disallowedTools, maxBudgetUsd, and cwd. Sessions run with --no-session-persistence; each invocation is a fresh, single-shot worker.

When several actors share the same model, effort, and permission mode, capture that once with claude.preset(...) instead of repeating it per actor:

import { claude } from "@veyorhq/anthropic/claude";
import { Reviewer } from "./actors.js";

const reviewWorker = claude.preset({
  model: "claude-opus-5",
  effort: "high",
  permissionMode: "dontAsk",
});

const ReviewerImpl = reviewWorker(Reviewer, {
  instructions: "Review the assignment against its acceptance criteria.",
});

claude.preset is sugar over claude — per-call options (including model) shallow-merge over the preset, with the per-call value winning.
