Copy Author

Add it

npx agentskit add marketing-copy-author

Use it

import { openai } from '@agentskit/adapters'
import { createMarketingCopyAuthorAgent } from './agents/marketing-copy-author/agent'

const agent = createMarketingCopyAuthorAgent({
  adapter: openai({ apiKey: process.env.OPENAI_API_KEY!, model: 'gpt-4o' }),
})
const { content } = await agent.run('…')

Or in one command: npx agentskit add marketing-copy-author --run "…" --provider ollama. Provider/model can also come from a .agentskit.config.json file.

Add tools, RAG, MCP, memory, permissions

import { webSearch } from '@agentskit/tools'
import { createMcpClient, toolsFromMcpClient } from '@agentskit/tools/mcp'

const agent = createMarketingCopyAuthorAgent({
  adapter,
  tools: [webSearch(), ...(await toolsFromMcpClient(await createMcpClient(/* … */)))], // tools + MCP
  retriever: rag.retrieve,             // RAG grounding
  memory,                              // conversation context
  onConfirm: (call) => approve(call),  // per-tool permission (HITL / RBAC)
  observers: [tracer],                 // tracing / audit
})

For orchestration, agents expose .asHandle() for supervisor / swarm. See Using.

agent.ts — the factory

import type {
  AdapterFactory,
  ChatMemory,
  Observer,
  Retriever,
  SkillDefinition,
  ToolCall,
  ToolDefinition,
} from '@agentskit/core'
import { createRuntime, type DelegateConfig } from '@agentskit/runtime'

const skill: SkillDefinition = {
  name: 'copy-author',
  description: 'Produces three distinct copy variants — bold/challenger, warm/story-led, and precise/evidence-based — from the structured brief and competitive context. Every variant targets a specific persona and channel.',
  systemPrompt: `You are Copy Author, the creative engine of the Marketing Campaign Studio.

You receive:
- A structured campaign brief from Brief Analyst (JSON)
- A competitive landscape report from Competitor Researcher
- Brand voice guide and persona documents from RAG

Your output is an array of exactly three copy variants:
[
  { "variantId": "bold", "headline": "...", "subheadline": "...", "body": "...", "cta": "...", "channel": "...", "targetPersona": "...", "toneRationale": "..." },
  { "variantId": "warm", ... },
  { "variantId": "precise", ... }
]

Variant guidelines:
- bold: challenger framing, provocative headline, benefit-led CTA. Best for LinkedIn.
- warm: story-led opening, empathy with the reader's pain, personal CTA. Best for email.
- precise: evidence-first, specific metrics cited, technical clarity. Best for product pages.

Rules:
- Never use banned phrases from the brand voice guide.
- Every metric must come from the brief or competitive report — no invented numbers.
- CTAs must match the funnel stage in the brief.
- Maximum body length: 150 words per variant.
- Return ONLY the JSON array. No preamble, no postscript.
