SkillHub CLI

SkillHub CLI is the official command-line tool for SkillHub, designed for searching, installing, managing, and publishing Agent skill packages.

📦 Installation

# Install globally via npm
npm install -g @astron-team/skillhub

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

# Or install globally via Bun
bun add -g @astron-team/skillhub

🚀 Quick Start

# Login
skillhub login --token sk_xxx

# Search skills
skillhub search pdf

# Install skill to Agent directory
skillhub install pdf-parser --agent codex

# List installed skills
skillhub list

# Publish skill
skillhub publish ./my-skill --namespace myspace

🌐 Registry Configuration

The active registry is resolved in the following priority order:

1. --registry <url> command-line argument
2. SKILLHUB_REGISTRY environment variable
3. registry in ~/.skillhub/config.json
4. Default value https://skill.xfyun.cn

# Temporarily use another registry
skillhub search pdf --registry https://skillhub.example.com

# Set via environment variable (Linux/macOS)
export SKILLHUB_REGISTRY=https://skillhub.example.com

Windows PowerShell:

$env:SKILLHUB_REGISTRY="https://skillhub.example.com"

Windows CMD:

set SKILLHUB_REGISTRY=https://skillhub.example.com

🔐 Authentication

Token resolution priority:

1. --token <token> command-line argument
2. SKILLHUB_TOKEN environment variable
3. Token stored in ~/.skillhub/credentials.json (per registry)

Login

# Login with API token
skillhub login --token sk_xxx

# Login to specific registry
skillhub login --token sk_xxx --registry https://skillhub.example.com

login validates the token, stores it in ~/.skillhub/credentials.json, and writes the registry to ~/.skillhub/config.json.

Check Current Identity

skillhub whoami

# Check specific registry
skillhub whoami --registry https://skillhub.example.com

# Temporarily use different token
skillhub whoami --token sk_other

Logout

skillhub logout

# Logout from specific registry
skillhub logout --registry https://skillhub.example.com

Logout only removes the token for the specified registry, preserving registry configuration and installation records.

🔍 Search

# Keyword search
skillhub search pdf

# List all skills (empty query)
skillhub search "" --limit 50

# JSON output
skillhub search pdf --json

Output format: namespace/slug version summary

📥 Install Skills

# Install to auto-detected Agent directory
skillhub install pdf-parser

# Specify namespace (default: global)
skillhub install pdf-parser --namespace myspace

# Specify version
skillhub install pdf-parser --version 1.2.0

# Install to specific Agent
skillhub install pdf-parser --agent codex

# Install to multiple Agents
skillhub install pdf-parser --agent codex --agent claude-code

# Install to custom directory
skillhub install pdf-parser --dir ~/.claude/skills

# Force overwrite existing installation
skillhub install pdf-parser --force

Install Target Resolution

The CLI determines the installation location using the following logic:

1. If --dir is specified: Install to that directory, agent marked as custom
2. If --agent is specified: Install to the corresponding Agent's skills directory
3. If neither is specified: Auto-scan current directory to detect existing Agent config directories
   • 1 Agent detected → Install directly
   • Multiple Agents detected → Interactive selection (TTY mode) or error (non-interactive mode)
   • No Agent detected → Fallback to <cwd>/.agents/skills/

--dir and --agent cannot be used together.

Install Paths

Each Agent has both project-level and user-level skills directories:

| Agent | Project-level Path | User-level Path | |-------|-------------------|-----------------| | claude-code | <project>/.claude/skills/ | ~/.claude/skills/ | | codex | <project>/.codex/skills/ | ~/.codex/skills/ | | cursor | <project>/.cursor/skills/ | ~/.cursor/skills/ | | github-copilot | <project>/.github-copilot/skills/ | ~/.github-copilot/skills/ | | gemini-cli | <project>/.gemini-cli/skills/ | ~/.gemini-cli/skills/ | | windsurf | <project>/.windsurf/skills/ | ~/.windsurf/skills/ | | kiro-cli | <project>/.kiro-cli/skills/ | ~/.kiro-cli/skills/ | | roo | <project>/.roo/skills/ | ~/.roo/skills/ | | trae | <project>/.trae/skills/ | ~/.trae/skills/ | | trae-cn | <project>/.trae-cn/skills/ | ~/.trae-cn/skills/ | | openhands | <project>/.openhands/skills/ | ~/.openhands/skills/ | | openclaw | <project>/.openclaw/skills/ | ~/.openclaw/skills/ | | opencode | <project>/.opencode/skills/ | ~/.opencode/skills/ | | kilo | <project>/.kilo/skills/ | ~/.kilo/skills/ |

For Agents not in the list, use --dir to specify the installation path.

File Structure After Installation

└── .skillhub/
    └── metadata.json            # Installation metadata

metadata.json example:

  "slug": "pdf-parser",

📋 Local Management

List Installed Skills

# List all installed skills
skillhub list

# Filter by Agent
skillhub list --agent codex

# Filter by multiple Agents
skillhub list --agent codex --agent claude-code

# Filter by directory
skillhub list --dir ~/.codex/skills

# JSON output
skillhub list --json

Remove Skills

# Remove all local installation targets
skillhub remove pdf-parser

# Remove only specific Agent's installation
skillhub remove pdf-parser --agent codex

# Remove all targets (skip interactive confirmation)
skillhub remove pdf-parser --all

# Remove remote skill (requires authentication, prompts for confirmation)
skillhub remove pdf-parser --remote --namespace myspace

# Skip remote deletion confirmation
skillhub remove pdf-parser --remote --hard --namespace myspace

Parameter exclusivity rules:

• --all cannot be used with --agent
• --remote cannot be used with --agent or --all
• Remote deletion in non-interactive environments requires --hard

Rebuild Local Inventory

skillhub doctor

doctor performs the following operations:

1. Scans <cwd>/.<agent>/skills/<slug>/.skillhub/metadata.json
2. Groups by registry + namespace + slug
3. Backs up old inventory.json (if exists)
4. Writes new inventory.json

If the same skill has version conflicts across different targets, that skill will be skipped and reported.

🚢 Publishing

# Publish directory (auto-packaged as zip)
skillhub publish ./my-skill --namespace myspace

# Publish existing zip file
skillhub publish ./my-skill.zip --namespace myspace

# Specify visibility
skillhub publish ./my-skill --namespace myspace --visibility private

Visibility options:

• public (default) — Visible to everyone
• namespace-only — Visible to namespace members only
• private — Visible to yourself only

After successful publication, the skill detail page URL will be displayed.

⬆️ Self-Update

# Check for new version
skillhub update --check

# Execute update
skillhub update

Update mechanism:

• Installed via npm globally: Auto-executes npm install -g @astron-team/skillhub@latest
• Installed via Bun globally: Auto-executes bun add -g @astron-team/skillhub@latest
• Run via npx: Prompts manual update command
• Unknown installation method: Prompts manual update

🔧 Environment Variables

| Variable | Description | Priority | |----------|-------------|----------| | SKILLHUB_REGISTRY | Default registry URL | Lower than --registry parameter | | SKILLHUB_TOKEN | API token | Lower than --token parameter, higher than stored token |

🔒 Security Notes

• Tokens are stored only in user directory ~/.skillhub/credentials.json
• On Linux/macOS, credential file permissions are automatically set to 0600
• Tokens are never written to any project-local files
• Remote delete operations require explicit confirmation or --hard parameter
• remove command validates path safety to prevent deletion of non-skill directories

🐛 Troubleshooting

Authentication Failure

# Verify token validity
skillhub whoami

# Re-login
skillhub login --token sk_xxx

Network Error

# Check if registry is accessible
curl https://skill.xfyun.cn/api/cli/v1/skills/search?q=test&limit=1

# Use alternative registry
skillhub search test --registry https://skillhub.example.com

Installation Directory Conflict

# Use --force to overwrite
skillhub install pdf-parser --force

# Or remove first then install
skillhub remove pdf-parser
skillhub install pdf-parser

Corrupted Inventory

# Rebuild inventory
skillhub doctor
