PR Review Agent

Add it

npx agentskit add pr-review

Use it

import { openai } from '@agentskit/adapters'
import { createPrReviewAgent } from './agents/pr-review/agent'

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

Or in one command: npx agentskit add pr-review --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 = createPrReviewAgent({
  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.

Packages

Building agents like this for production? See the Agents Playbook for the patterns behind them.

Required env
