SkillHub is a self-hosted platform that gives teams a private, governed place to share agent skills. Publish a skill package, push it to a namespace, and let others find it through search or install it via CLI. Built for on-premise deployment behind your firewall, with the same polish you'd expect from a public registry.

⭐ If SkillHub fits your team, star the repo to help other teams find it, and Watch → Custom → Releases to get notified when a new version ships.

Share Great Skills

Great Skills become more valuable when they are shared. If you have a Skill that has proved useful in real work or everyday life, share it with the SkillHub community and help grow an open, practical Skill ecosystem. We welcome Skills for daily life, office work, learning and research, travel and events, content creation, data analysis, and software development—not only engineering workflows.

High-quality community contributions may join the curated starter collection, making new SkillHub deployments useful from day one. You do not need to finish the full adaptation before joining in: open an issue with the Skill's source and the problem it solves, or submit a PR by following the Skill sharing guide.

Documentation

• 📖 User Guide — Skill publishing, search, CLI usage and other user guides
• 🛠️ Developer Docs — Architecture, API reference, local development, deployment and operations
• 🐍 Python Examples — Search, download, and publish skills from Python via the REST API

Governance and Safety

• Privacy and Data Governance — Data categories, operator responsibilities, retention, portability, and incident handling for public and self-hosted instances

Highlights

• Self-Hosted & Private — Deploy on your own infrastructure. Keep proprietary skills behind your firewall with full data sovereignty. One make dev-all command to get running locally.
• Publish & Version — Upload agent skill packages with semantic versioning, custom tags (beta, stable), and automatic latest tracking.
• Discover — Full-text search with filters by namespace, downloads, ratings, and recency. Visibility rules ensure users only see what they're authorized to.
• Team Namespaces — Organize skills under team or global scopes. Each namespace has its own members, roles (Owner / Admin / Member), and publishing policies.
• Review & Governance — Team admins review within their namespace; platform admins gate promotions to the global scope. Governance actions are audit-logged for compliance.
• Social Features — Star skills, rate them, and track downloads. Build a community around your organization's best practices.
• Account Merging — Consolidate multiple OAuth identities and API tokens under a single user account.
• API Token Management — Generate scoped tokens for CLI and programmatic access with prefix-based secure hashing.
• CLI-First — Native REST API plus a compatibility layer for existing ClawHub-style registry clients. Native CLI APIs are the primary supported path while protocol compatibility continues to expand.
• Pluggable Storage — Local filesystem for development, S3 / MinIO for production. Swap via config.
• Internationalization — Multi-language support with i18next.

Quick Start

Start the full local stack with:

rm -rf /tmp/skillhub-runtime
curl -fsSL https://imageless.oss-cn-beijing.aliyuncs.com/runtime.sh | sh -s -- up

The default command pulls the latest stable release images. Use --version edge if you want the newest build from main.

Configure public URL (recommended for production):

curl -fsSL https://imageless.oss-cn-beijing.aliyuncs.com/runtime.sh | sh -s -- up --public-url https://skillhub.your-company.com

The --public-url parameter sets the public access URL for your SkillHub instance. This ensures:

• CLI install commands show the correct registry URL
• Agent setup instructions display the correct skill.md URL
• OAuth callbacks and device auth links work properly

For users in China (Aliyun mirror):

curl -fsSL https://imageless.oss-cn-beijing.aliyuncs.com/runtime.sh | sh -s -- up --aliyun --public-url https://skillhub.your-company.com --version latest

If deployment runs into problems, clear the existing runtime home and retry.

SkillHub CLI

Install and manage Agent skills from the command line:

# Install CLI
npm install -g @astron-team/skillhub

# Or run directly
npx @astron-team/skillhub@latest version

# Login
skillhub login --token sk_xxx --registry https://skill.xfyun.cn

# Search and install skills
skillhub search pdf
skillhub install pdf-parser --agent codex

# List installed skills
skillhub list

Prerequisites

• Docker & Docker Compose

Local Development

make dev-all

For developers in China: If Maven dependency download times out, configure Aliyun mirror. See Local Development Guide for details.

Then open:

• Web UI: http://localhost:3000
• Backend API: http://localhost:8080

By default, make dev-all starts the backend with the local profile. In that mode, local development keeps the mock-auth users below and also creates a password-based bootstrap admin account by default:

• local-user for normal publishing and namespace operations
• local-admin with SUPER_ADMIN for review and admin flows

Use them with the X-Mock-User-Id header in local development.

The local bootstrap admin is enabled by default in application-local.yml:

• username: admin
• password: ChangeMe!2026
• To disable it, set BOOTSTRAP_ADMIN_ENABLED=false before starting the backend.

Stop everything with:

make dev-all-down

Reset local dependencies and start from a clean slate with:

make dev-all-reset

Run make help to see all available commands.

Useful backend commands:

make test
make test-backend-app
make build-backend-app

Do not run ./mvnw -pl skillhub-app clean test directly under server/. skillhub-app depends on sibling modules in the same repo, and a standalone clean build can fall back to stale artifacts from the local Maven repository, which surfaces misleading cannot find symbol and signature-mismatch errors. Use -am, or the make test-backend-app and make build-backend-app targets above.

For the full development workflow (local dev → staging → PR), see docs/dev-workflow.md.

API Contract Sync

OpenAPI types for the web client are checked into the repository. When backend API contracts change, regenerate the SDK and commit the updated generated file:

make generate-api

For a stricter end-to-end drift check, run:

./scripts/check-openapi-generated.sh

This starts local dependencies, boots the backend, regenerates the frontend schema, and fails if the checked-in SDK is stale.

Container Runtime

Published runtime images are built by GitHub Actions and pushed to GHCR. This is the supported path for anyone who wants a ready-to-use local environment without building the backend or frontend on their machine. Published server and web images target linux/amd64, linux/arm64, and linux/riscv64; the scanner image currently targets linux/amd64 and linux/arm64.

Quick deployment with curl:

# Default (GHCR images)
curl -fsSL https://imageless.oss-cn-beijing.aliyuncs.com/runtime.sh | sh -s -- up --public-url https://skillhub.your-company.com

# Aliyun mirror (recommended for users in China)
curl -fsSL https://imageless.oss-cn-beijing.aliyuncs.com/runtime.sh | sh -s -- up --aliyun --public-url https://skillhub.your-company.com --version latest

Deployment parameters:

Important: Configure --public-url for production deployments to ensure CLI install commands and Agent setup instructions display the correct URLs.

For sub-path deployments, keep the public URL and runtime base path aligned in .env.release: set SKILLHUB_PUBLIC_BASE_URL=https://skill.example.com/skillhub, SKILLHUB_WEB_BASE_PATH=/skillhub/, and SKILLHUB_WEB_API_BASE_URL=/skillhub.

Manual deployment:

1. Copy the runtime environment template.
2. Pick an image tag.
3. Start the stack with Docker Compose.

cp .env.release.example .env.release

Recommended image tags:

• SKILLHUB_VERSION=latest for the latest stable release (default)
• SKILLHUB_VERSION=edge for the latest main build
• SKILLHUB_VERSION=vX.Y.Z for a fixed release

Start the runtime:

make validate-release-config
docker compose --env-file .env.release -f compose.release.yml up -d

Then open:

• Web UI: SKILLHUB_PUBLIC_BASE_URL 对应的地址
• Backend API: http://localhost:8080

Stop it with:

docker compose --env-file .env.release -f compose.release.yml down

The runtime stack uses its own Compose project name, so it does not collide with containers from make dev-all.

The production Compose stack now defaults to the docker profile only. It does not enable local mock auth. The release template (.env.release.example) enables the bootstrap admin by default, so zero-config quickstart via runtime.sh works out of the box:

• username: admin
• password: ChangeMe!2026

Recommended production baseline:

• set SKILLHUB_PUBLIC_BASE_URL to the final HTTPS entrypoint
• if the service is published under a sub-path such as /skillhub/, set SKILLHUB_WEB_BASE_PATH=/skillhub/ and SKILLHUB_WEB_API_BASE_URL=/skillhub as well
• keep PostgreSQL / Redis bound to 127.0.0.1
• use external S3 / OSS via SKILLHUB_STORAGE_S3_*
• change BOOTSTRAP_ADMIN_PASSWORD to a strong password (validate-release-config.sh rejects the default ChangeMe!2026)
• rotate or disable the bootstrap admin after initial setup
• run make validate-release-config before docker compose up -d

If the GHCR package remains private, run docker login ghcr.io before docker compose up -d.

Upload Allowlist Override

Skill package upload validation uses the default extension allowlist from SkillPackagePolicy.java. SkillPublishProperties uses that same list by default for skillhub.publish.allowed-file-extensions.

If you need to replace the default allowlist at runtime, set:

SKILLHUB_PUBLISH_ALLOWED_FILE_EXTENSIONS=.md,.json,.xsd,.xsl,.dtd,.docx,.xlsx,.pptx

Spring Boot binds this environment variable to skillhub.publish.allowed-file-extensions. When set, it replaces the default allowlist instead of appending to it.

Monitoring

A Prometheus + Grafana monitoring stack lives under monitoring/. It scrapes the backend's Actuator Prometheus endpoint.

Start it with:

cd monitoring
docker compose -f docker-compose.monitoring.yml up -d

Then open:

• Prometheus: http://localhost:9090
• Grafana: http://localhost:3001 (admin / admin)

By default Prometheus scrapes http://host.docker.internal:8080/actuator/prometheus, so start the backend locally on port 8080 first.

Kubernetes

Basic Kubernetes manifests are available under deploy/k8s/:

• configmap.yaml
• secret.yaml.example
• backend-deployment.yaml
• frontend-deployment.yaml
• services.yaml
• ingress.yaml

For a configurable deployment with bundled PostgreSQL and Redis dependencies, use the Helm chart under charts/skillhub/:

helm dependency build ./charts/skillhub
helm upgrade --install skillhub ./charts/skillhub \
  --namespace skillhub \
  --create-namespace \
  -f values-production.yaml

See the Helm chart guide for required secrets, Ingress/TLS, external data services, storage migration, and upgrade constraints.

Apply them after creating your own secret:

kubectl apply -f deploy/k8s/configmap.yaml
kubectl apply -f deploy/k8s/secret.yaml
kubectl apply -f deploy/k8s/backend-deployment.yaml
kubectl apply -f deploy/k8s/frontend-deployment.yaml
kubectl apply -f deploy/k8s/services.yaml
kubectl apply -f deploy/k8s/ingress.yaml

Smoke Test

A lightweight smoke test script is available at scripts/smoke-test.sh.

Run it against a local backend:

./scripts/smoke-test.sh http://localhost:8080

Local Compose and staging runs can keep using one backend URL. For an ingress deployment where the public URL exposes application APIs but keeps Actuator on the backend service, set a separate Actuator target:

ACTUATOR_BASE_URL=http://skillhub-server:8080 \
  ./scripts/smoke-test.sh https://skillhub.example.com

The health check requires an Actuator JSON response, so an HTML SPA fallback is reported as a routing or target error instead of a successful health response.

Admin label-management smoke checks run only when current admin credentials are supplied explicitly:

SMOKE_ADMIN_USERNAME=admin SMOKE_ADMIN_PASSWORD='current-password' \
  ./scripts/smoke-test.sh http://localhost:8080

Use SMOKE_ADMIN_CHECKS=false for persistent environments where only non-admin smoke checks should run. The script no longer falls back to bootstrap admin password defaults.

SkillHub and the Agent Skills Ecosystem

SkillHub is a registry and governance platform — not a skill collection. It is complementary to open skill catalogs such as anthropics/skills: that repository popularized the Agent Skill format (a SKILL.md with name / description frontmatter plus supporting files) and ships a curated set of example skills. SkillHub is where your organization hosts, versions, governs, and distributes those skills privately.

Because SkillHub speaks the same SKILL.md format, skills from anthropics/skills — or any Agent Skill folder — publish straight into your registry:

# Grab a skill from an open collection...
git clone https://github.com/anthropics/skills

# ...and publish it into your private SkillHub registry
export CLAWHUB_REGISTRY=https://skillhub.your-company.com
npx clawhub publish ./skills/<category>/<skill-name>

⚖️ Licensing: honor each skill's own license when republishing. Most skills in anthropics/skills are Apache 2.0, but the document skills (DOCX/PDF/PPTX/XLSX) are source-available rather than open source — check the skill's LICENSE before redistributing.

In short: use collections like anthropics/skills for content, and SkillHub to distribute it across your organization under governance.

Usage with Agent Platforms

SkillHub works as a skill registry backend for several agent platforms. Point any of the clients below at your SkillHub instance to publish, discover, and install skills.

OpenClaw

OpenClaw is an open-source agent skill CLI. Configure it to use your SkillHub endpoint as the registry:

# Configure registry URL
export CLAWHUB_REGISTRY=https://skillhub.your-company.com

# Authenticate once if needed
clawhub login --token YOUR_API_TOKEN

# Search and install skills
npx clawhub search email
npx clawhub install my-skill
npx clawhub install my-namespace--my-skill

# Publish to global namespace
npx clawhub publish ./my-skill --slug my-skill --version 1.0.0

# Publish to a team namespace such as my-space
npx clawhub publish ./my-skill --slug my-space--my-skill --version 1.0.0

my-space--my-skill is the canonical compat slug. SkillHub parses it as namespace my-space plus skill slug my-skill.

💡 Tip: The above commands are not only applicable to OpenClaw, but also to other CLI Coding Agents or Agent assistants by specifying the installation directory (--dir). For example: npx clawhub --dir ~/.claude/skills install my-skill

Hermes Agent

Hermes Agent uses the standard SKILL.md format and recursively discovers skills under $HERMES_HOME/skills/. Use SkillHub CLI's explicit --dir option to install a complete SkillHub package into Hermes without a registry adapter, then verify it with hermes skills list.

HarnessClaw Engine

HarnessClaw Engine is a Go LLM programming assistant engine that exposes its capabilities over WebSocket. It loads skills from SKILL.md files with YAML frontmatter and parameter substitution, scanning each configured directory for skill-name/SKILL.md (default ~/.harnessclaw/workspace/skills/, with earlier directories taking priority on name conflicts). Install a SkillHub package straight into that directory with the CLI's --dir option, no registry adapter required:

npx clawhub --dir ~/.harnessclaw/workspace/skills install my-skill

AstronClaw

AstronClaw is a cloud AI assistant built on OpenClaw's core capabilities, providing 24/7 online service through enterprise platforms like WeChat Work, DingTalk, and Feishu. It features a built-in skill system with over 130 official skills. You can connect it to a self-hosted SkillHub registry to enable one-click skill installation, search repository, dialogue-based automatic installation, and even custom skills management within your organization.

Loomy

Loomy is a desktop AI work partner focusing on real office scenarios. It integrates deeply with local files and system tools to build efficient automated workflows for individuals and small teams. By connecting Loomy to your SkillHub registry, you can easily discover and install organization-specific skills to enhance your local desktop automation and productivity.

astron-agent

astron-agent is the iFlytek Astron agent framework. Skills stored in SkillHub can be referenced and loaded by astron-agent, enabling a governed, versioned skill lifecycle from development to production.

Related Projects

SkillHub is part of the iFlytek Astron open-source ecosystem. If SkillHub is useful to you, these sibling projects may be too:

• astron-agent — Enterprise-grade, commercial-friendly agentic workflow platform for building next-generation SuperAgents. Skills published to SkillHub can be loaded and run by astron-agent.
• astron-rpa — Agent-ready RPA suite with out-of-the-box automation tools, built for individuals and enterprises.
