Anthropic Claude AgentRunner adapter for @pmcollab/coworkstream-engine.

Install

npm install @pmcollab/coworkstream-engine-anthropic @anthropic-ai/sdk

Use

import Anthropic from '@anthropic-ai/sdk'
import { createEngine, weightedVote, createMemoryStore, createMemoryTrustModel } from '@pmcollab/coworkstream-engine'
import { createAnthropicAgent } from '@pmcollab/coworkstream-engine-anthropic'

const client = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY })

const engine = createEngine({
  agents: [
    createAnthropicAgent({
      id: 'risk',
      client,
      model: 'claude-sonnet-4-6',
      system: 'You are a risk reviewer. Evaluate proposed actions for risk to revenue.',
    }),
    createAnthropicAgent({
      id: 'finance',
      client,
      model: 'claude-haiku-4-5',
      system: 'You are a finance reviewer. Evaluate cost and budget impact.',
    }),
  ],
  alignmentStrategy: weightedVote(),
  store: createMemoryStore(),
  trustModel: createMemoryTrustModel(),
})

await engine.process({ id: 'i1', category: 'decision', title: 'Discount: Globex Q4' })

How it works

• The adapter ships a respond tool that the model uses to record its decision (position, reasoning, confidence).
• Position is taken from the tool's position argument (preferred) or extracted from the model's text output (fallback).
• confidence defaults to 0.7 when the model returns text instead of using the tool.

Options

  id,                           // required

  name?, avatar?, capabilities?,
  model?: string,               // default 'claude-sonnet-4-6'
  system?: string,
  maxTokens?: number,           // default 1024
  defaultConfidence?: number,   // default 0.7
  formatItem?: (item, ctx) => string,
  extraTools?: AnthropicTool[],
})
