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.
| Feature | Package | Command |
|---|---|---|
| Terminal UI | @skillkit/tui |
skillkit ui |
| REST server | @skillkit/api |
skillkit serve |
| Peer mesh | @skillkit/mesh |
skillkit mesh |
| Agent messaging | @skillkit/messaging |
skillkit message |
Cold install numbers on a fresh npm cache:
| Mode | Packages | Time | Vulns (crit/high) |
|---|---|---|---|
npm i -g skillkit |
418 | 18s | 0/0 |
npm i -g skillkit --omit=optional |
118 | 9s | 0/0 |
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.

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');
