@agentskit/skills

Pre-tuned agent personas that work out of the box — skills are what your agent IS, tools are what it CAN DO.

Why skills

• Skip prompt engineering — researcher, coder, planner, critic, and summarizer are battle-tested behavioral profiles; activate one and your agent immediately behaves like a specialist
• Composable by design — combine skills with composeSkills to merge prompts, tools, and delegates; build a research-and-code pipeline in one line
• Multi-agent delegation built in — the planner skill knows how to coordinate researcher and coder as sub-agents, so you get multi-agent workflows without writing orchestration code
• Extend without starting over — override just systemPrompt or temperature on top of an existing skill via @agentskit/templates

Install

npm install @agentskit/skills

Quick example

import { createRuntime } from '@agentskit/runtime'
import { anthropic } from '@agentskit/adapters'
import { researcher, coder, composeSkills } from '@agentskit/skills'
import { webSearch, filesystem } from '@agentskit/tools'

const runtime = createRuntime({
  adapter: anthropic({ apiKey: process.env.ANTHROPIC_API_KEY, model: 'claude-sonnet-4-6' }),
  tools: [webSearch(), ...filesystem({ basePath: './workspace' })],
})

const result = await runtime.run('Research best practices for TypeScript error handling and write an example', {
  skill: composeSkills(researcher, coder),
})
console.log(result.content)

Features

• Built-in skills: researcher, coder, planner, critic, summarizer, codeReviewer, prReviewer, sqlGen, dataAnalyst, translator
• composeSkills(...skills) — merge system prompts and behavioral defaults
• Skill contract v1 (ADR 0005): { name, description, systemPrompt }
• Works with @agentskit/runtime, useChat, and the CLI --skill flag
• Fork and override with @agentskit/templates createSkillTemplate
