AI Agent Skills

My curated library of agent skills, plus the package to build your own.

The skills I actually keep around, organized the way I work.

_{17 house copies · 93 cataloged upstream}

Picked, shelved, and maintained by hand.

Build your own library · For your agent

Library

ai-agent-skills does two things.

It ships my curated library, and it gives you the CLI and TUI to build and manage your own.
It works with any Agent Skills-compatible agent.

The bundled library is organized the way I work:

• Start with a shelf like frontend or workflow
• Keep the set small enough to browse quickly
• Keep provenance visible
• Keep notes that explain why a skill is here

Use skills.sh for the broad ecosystem.
Use ai-agent-skills when you want a smaller library with shelves, provenance, and notes.

What's New in 4.2.0

• Managed team libraries you can share over GitHub and install with install <owner>/<repo>
• Machine-readable CLI flows with --format json, --fields, pagination, and safer non-interactive output
• More authored workflow skills for curating, reviewing, syncing, and sharing libraries
• Dependency-aware installs, sync as the main refresh verb, and stronger installed-state visibility across the CLI and TUI
• A cleaner curator loop around shelves, provenance, trust, and shared starter packs

What It Is Now

I launched this on December 17, 2025, before skills.sh existed and before the ecosystem had a clear default universal installer.

Originally this repo was that installer. It still does that.

What started as an installer is now a place to build and manage your own library of skills.

How It Works

Each skill here is either a house copy or a cataloged upstream pick.

• House copies
  Local folders under skills/<name>/.
  These install fast, work offline, and ship with the npm package.

• Cataloged upstream
  Metadata in skills.json with no local folder.
  These stay upstream and install from the source repo when you ask for them.

Upstream work stays upstream. That keeps the library lean.

For Your Agent

Tell your agent to build you a library. Paste this, or just point it at this repo — the protocol below has everything it needs.

Full protocol with curator decision framework: FOR_YOUR_AGENT.md

Paste this into your agent

Set up a managed team skills library for me with `ai-agent-skills`.

Read the full agent protocol here before starting:
https://raw.githubusercontent.com/MoizIbnYousaf/Ai-Agent-Skills/main/FOR_YOUR_AGENT.md

Use the CLI with `npx`. Do not hand-edit `skills.json`, `README.md`, or `WORK_AREAS.md` if the command already exists.

1. Fetch and read FOR_YOUR_AGENT.md above — it has the full curator decision protocol.
2. Create a workspace with `npx ai-agent-skills init-library <name>`.
3. Ask me at most 3 short questions: what kinds of work, small or broad, local draft or shared repo.
4. Map my stack to shelves: frontend, backend, mobile, workflow, agent-engineering.
5. Run a discovery loop: `list --area <shelf>`, `search <query>`, `collections`.
6. Add 3-8 skills with explicit `--area`, `--branch`, and `--why` on every mutation.
7. Run `npx ai-agent-skills build-docs` before finishing.
8. If I want it shared: `git init && git add . && git commit -m "Initialize skills library" && gh repo create`.
9. Tell me what you added, which shelves, and the install command for teammates.

The companion workflow skills (installed automatically when you use the library):

npx ai-agent-skills install install-from-remote-library
npx ai-agent-skills install curate-a-team-library
npx ai-agent-skills install share-a-library
npx ai-agent-skills install browse-and-evaluate
npx ai-agent-skills install update-installed-skills
npx ai-agent-skills install build-workspace-docs
npx ai-agent-skills install review-a-skill
npx ai-agent-skills install audit-library-health
npx ai-agent-skills install migrate-skills-between-libraries

Quick Start

Use the bundled library

# Open the terminal browser
npx ai-agent-skills

# List the shelves
npx ai-agent-skills list

# Install a skill from the library
npx ai-agent-skills install frontend-design

# Install the Swift hub to the default global targets
npx ai-agent-skills swift

# Install an entire curated pack
npx ai-agent-skills install --collection swift-agent-skills -p

# Install the mktg marketing pack
npx ai-agent-skills mktg
npx ai-agent-skills marketing-cli

# Install to the project shelf
npx ai-agent-skills install pdf -p

# Install all skills from an upstream repo to the default global targets
npx ai-agent-skills anthropics/skills

# Browse a repo before adding or installing from it
npx ai-agent-skills install openai/skills --list

Default install targets:

• Global: ~/.claude/skills/
• Project: .agents/skills/

Legacy agent-specific targets still work through --agent <name>.

Start your own library

# Create a managed workspace
npx ai-agent-skills init-library my-library
cd my-library

# Add a bundled pick, install it, refresh it, and rebuild the docs
npx ai-agent-skills add frontend-design --area frontend --branch Implementation --why "I want this on my shelf."
npx ai-agent-skills install frontend-design -p
npx ai-agent-skills sync frontend-design -p
npx ai-agent-skills add anthropics/skills --skill webapp-testing --area workflow --branch Testing --why "I use this when I want browser-level checks in the workspace."
npx ai-agent-skills build-docs

# Or bootstrap an existing flat repo of skills in place
cd ~/projects/my-skills
npx ai-agent-skills init-library . --areas "mobile,workflow,agent-engineering" --import --auto-classify
npx ai-agent-skills browse

# Invalid private-only names are skipped and reported.
# Low-confidence imports fall back to workflow with a needs-curation label.

Workspace Mode

Workspace mode is part of the normal flow now.

Start with a managed workspace, add a few skills, then keep your shelves current with add, catalog, vendor, sync, and build-docs.

npx ai-agent-skills init-library my-library
cd my-library

npx ai-agent-skills add frontend-design --area frontend --branch Implementation --why "I want this on my shelf."
npx ai-agent-skills install frontend-design -p
npx ai-agent-skills add anthropics/skills --skill webapp-testing --area workflow --branch Testing --why "I use this when I want browser-level checks in the workspace."
npx ai-agent-skills sync frontend-design -p
npx ai-agent-skills build-docs

# Bulk import an existing library after bootstrap
npx ai-agent-skills import --auto-classify

# Review the fallback bucket and fix shelf placement
npx ai-agent-skills list --area workflow
npx ai-agent-skills curate some-skill --area mobile --branch "Mobile / Testing" --why "Why it belongs."

Workflow guides:

• Start a library
• Add an upstream skill
• Make a house copy
• Organize shelves
• Refresh installed skills

Browse

Most browsing starts in one of two places:

View	Why it exists	Start here
Shelves	The main way to understand the library: start with the kind of work, then drill into the small set of picks on that shelf.	npx ai-agent-skills list
Sources	The provenance view: see which publishers feed which shelves and branches.	npx ai-agent-skills info frontend-design

The other views are still useful, just more situational:

• npx ai-agent-skills browse for the TUI
• npx ai-agent-skills list --collection my-picks for a cross-shelf starter stack
• npx ai-agent-skills install --collection swift-agent-skills -p for an installable curated pack
• npx ai-agent-skills curate review for the curator cleanup queue

Shelves

The shelves are the main structure.

Shelf	Skills	What it covers
Frontend	10	Interfaces, design systems, browser work, and product polish.
Backend	5	Systems, data, security, and runtime operations.
Mobile	24	Swift, SwiftUI, iOS, and Apple-platform development, with room for future React Native branches.
Workflow	11	Files, docs, planning, release work, and research-to-output flows.
Agent Engineering	14	MCP, skill-building, prompting discipline, and LLM application work.
Marketing	46	Brand, strategy, copy, distribution, creative, SEO, conversion, and growth work.

The full map lives in WORK_AREAS.md.

Collections

Collections are smaller sets. Useful, but secondary to the shelves.

Collection	Why it exists	Start here
my-picks	A short starter stack. These are the skills I reach for first.	frontend-design, mcp-builder, pdf
build-apps	Frontend, UI, and design work for shipping polished apps.	frontend-design, frontend-skill, shadcn
swift-agent-skills	The main Swift and Apple-platform set in this library. Install it all at once or pick from it.	swiftui-pro, swiftui-ui-patterns, swiftui-design-principles
build-systems	Backend, architecture, MCP, and security work.	mcp-builder, backend-development, database-design
test-and-debug	QA, debugging, CI cleanup, and observability.	playwright, webapp-testing, gh-fix-ci
docs-and-research	Docs, files, research, and writing work.	pdf, doc-coauthoring, docx
mktg	The full upstream mktg marketing playbook. Install the whole set at once or pick from it.	cmo, brand-voice, positioning-angles

Curating the catalog

Use catalog when you want to add an upstream skill without vendoring it.

In a managed workspace, start with add.
Use catalog and vendor when you want more control.

npx ai-agent-skills catalog openai/skills --list
npx ai-agent-skills catalog openai/skills --skill linear --area workflow --branch Linear
npx ai-agent-skills catalog openai/skills --skill security-best-practices --area backend --branch Security
npx ai-agent-skills catalog conorluddy/ios-simulator-skill --skill ios-simulator-skill --area mobile --branch "Swift / Tools" --collection swift-agent-skills
npx ai-agent-skills catalog shadcn-ui/ui --skill shadcn --area frontend --branch Components

It does not create a local copy.
It adds metadata and placement in the active library:

• which shelf it belongs on
• what branch it lives under
• why it earned a place
• how it should install later

For existing picks, use curate for quick edits:

npx ai-agent-skills curate frontend-design --branch Implementation
npx ai-agent-skills curate ios-simulator-skill --collection swift-agent-skills
npx ai-agent-skills curate ios-simulator-skill --remove-from-collection swift-agent-skills
npx ai-agent-skills curate frontend-design --why "A stronger note that matches how I actually use it."
npx ai-agent-skills curate review

When I want a local copy, I use vendor:

npx ai-agent-skills vendor <repo-or-path> --skill <name> --area <shelf> --branch <branch> --why "Why this deserves a local copy."
npx ai-agent-skills vendor <repo-or-path> --skill <name> --area mobile --branch "Swift / Tools" --collection swift-agent-skills --why "Why this deserves a place in the Swift pack."

The two biggest upstream publishers in this library are Anthropic and OpenAI.
I browse, pick, and shelve. I do not mirror everything they publish.

Testing

• npm test
  Fast regression coverage for CLI behavior, schema rules, routing, and local install flows.
• npm run test:live
  No-mock live verification. Clones the real upstream repos, captures raw SKILL.md frontmatter and file manifests, runs real install/sync/uninstall flows in isolated temp homes and projects, drives the TUI through a real PTY, and writes a report to tmp/live-test-report.json.
• npm run test:live:quick
  A smaller live matrix for faster iteration with the same no-mock pipeline.

Legacy Agent Support

Still supported through --agent <name>:

• claude
• cursor
• codex
• amp
• vscode
• copilot
• gemini
• goose
• opencode
• letta
• kilocode
• project

What I Care About

• Small shelves
• Clear provenance
• Notes that explain why something stays
• Upstream repos staying upstream
• A library that looks cared for
