The problem

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

AgentFormatDirectory
Claude CodeSKILL.md.claude/skills/
Cursor.mdc.cursor/skills/
CopilotMarkdown.github/skills/
WindsurfMarkdown.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.

FeaturePackageCommand
Terminal UI@skillkit/tuiskillkit ui
REST server@skillkit/apiskillkit serve
Peer mesh@skillkit/meshskillkit mesh
Agent messaging@skillkit/messagingskillkit message

Cold install numbers on a fresh npm cache:

118 packages 9s install 0 vulnerabilities

ModePackagesTimeVulns (crit/high)
npm i -g skillkit41818s0/0
npm i -g skillkit --omit=optional1189s0/0

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 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');
