One skill. Every agent. 46 of them.

The problem
Every AI coding agent wants skills. Every agent invented a different format.
| Agent | Format | Directory |
|---|---|---|
| Claude Code | SKILL.md | .claude/skills/ |
| Cursor | .mdc | .cursor/skills/ |
| Copilot | Markdown | .github/skills/ |
| Windsurf | Markdown | .windsurf/skills/ |
| ... 41 more | ||
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 <owner/repo> 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.
What you can do
Install from anywhere
skillkit add anthropics/skills # GitHub
skillkit add gitlab:team/skills # GitLab
skillkit add ./my-local-skills # local path
skillkit add https://gist.github.com/... # gist
Translate between agents
Write once for Claude, ship everywhere:
skillkit translate my-skill --to cursor
skillkit translate --all --to windsurf,codex
skillkit translate my-skill --to copilot --dry-run
Stack-aware recommendations
SkillKit reads your repo, spots your stack, ranks skills:
$ skillkit recommend
92% vercel-react-best-practices
87% tailwind-v4-patterns
85% nextjs-app-router
81% shadcn-ui-components
Runtime skill discovery (REST)
Start the server, let agents fetch skills on demand:
skillkit serve
# http://localhost:3737
curl "http://localhost:3737/search?q=react+performance"
Or wire it up with MCP:
{
"mcpServers": {
"skillkit": { "command": "npx", "args": ["@skillkit/mcp"] }
}
}
Or call from Python:
from skillkit import SkillKitClient
async with SkillKitClient() as client:
results = await client.search("react performance", limit=5)
Auto-generate agent instructions
Analyze the codebase and write CLAUDE.md, .cursorrules, AGENTS.md, and friends:
skillkit primer --all-agents
Session memory
AI agents learn during a session, then forget. SkillKit captures what they learned:
skillkit memory compress
skillkit memory search "auth patterns"
skillkit memory export auth-patterns
AI skill generation
Generate skills from plain English with multi-source context:
skillkit generate
Pulls context from four places: Context7 docs, your codebase, 400K marketplace skills, your memory. Works with Claude, GPT-4, Gemini, Ollama (local), or any OpenRouter model.
Team collaboration
Share skills via a committable .skills manifest:
skillkit manifest init
skillkit manifest add anthropics/skills
git commit -m "add team skills"
Everyone else runs skillkit manifest install and matches state.
Mesh network
Distribute agents across machines with encrypted P2P:
skillkit mesh init
skillkit mesh discover
Chrome extension
Save any webpage as a skill from the browser. Click the extension, the page round-trips through the SkillKit API (Turndown, 5-source tag detection, GitHub URL support), the SKILL.md downloads, then run skillkit add ~/Downloads/skillkit-skills/<name>.

Creating skills
skillkit create my-skill
Or author a SKILL.md by hand:
---
name: my-skill
description: What this skill does

# 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');
