The problem

Every AI coding agent wants skills. Every agent invented a different format.

You rewrite the same skill for each agent. Or you lock in to one.

The fix

SkillKit is the package manager for AI agent skills. Install from 400K+ skills across 31 sources. Auto-translate between formats. Persist session learnings. Ship to 46 agents at once.

npx skillkit add anthropics/skills

That is the whole first-run. Pick your agent (your detected agent is pre-selected), confirm, done.

Quick start

npx skillkit init                     # detect agent, create dirs
skillkit recommend                    # stack-aware suggestions
skillkit add anthropics/skills        # install from marketplace
skillkit sync                         # deploy to agent config

Four commands. Your agent now has PDF processing, code review, auth patterns, and whatever you need.

What the first install looks like

$ npx skillkit add anthropics/skills

 ◇ Detected 32 agents
 │
 ◆ Install to
 │  ● Just Claude Code (detected)      claude-code
 │  ○ Select specific agents           space to toggle
 │  ○ All supported agents             32 agents, writes to every adapter
 └

 ◇ Cloning anthropics/skills
 ◇ Security scan: 42/42 skills pass
 ◇ Installed 42 skills to Claude Code
 │
 └ Done in 3.1s. Run `skillkit list` to see them.

Install

Pick one. All three do the same thing.

npm install -g skillkit       # npm
pnpm add -g skillkit          # pnpm
bun add -g skillkit           # bun

Both skillkit and sk work as the binary name.

Full vs slim

Four features ship as optional packages so a bare CLI stays small. The default install pulls everything. Add --omit=optional if you only want the core.

Cold install numbers on a fresh npm cache:

Skipped optional? Add just the one you want later:

npm i -g @skillkit/tui         # enables: skillkit ui
npm i -g @skillkit/api         # enables: skillkit serve
npm i -g @skillkit/mesh        # enables: skillkit mesh
npm i -g @skillkit/messaging   # enables: skillkit message

The CLI catches missing optional packages and prints a one-line hint. No stack trace.

Using npx

npx skillkit add works with zero install. First call caches the package under ~/.npm/_npx/. Every run after that is instant until a new version ships.

npx skillkit add anthropics/skills                    # full
npx --omit=optional skillkit add anthropics/skills    # slim

If you reach for npx skillkit more than twice, switch to a global install. Kills the prompt-to-proceed and the per-release refetch.

Creating skills

skillkit create my-skill

Or author a SKILL.md by hand:

---
name: my-skill
description: What this skill does
license: MIT

# My Skill

Instructions for the agent.

## When to use
- scenario 1
- scenario 2

## Steps
1. first
2. second

Programmatic API

import { translateSkill, analyzeProject, RecommendationEngine } from 'skillkit';

const skill = await translateSkill(content, 'cursor');

const profile = await analyzeProject('./my-project');
const engine = new RecommendationEngine();
const recs = await engine.recommend(profile);

import { startServer } from '@skillkit/api';
await startServer({ port: 3737, skills: [...] });

import { MemoryCache, RelevanceRanker } from '@skillkit/core';
const cache = new MemoryCache({ maxSize: 500, ttlMs: 86_400_000 });
const ranker = new RelevanceRanker();
const results = ranker.rank(skills, 'react performance');
