AI Skills

A collection of useful skills for AI agents (like Claude Code/ Codex/ GitHub Copilot CLI), following the Agent Skills specification.

Skills

Skill	Description	Screenshot
Image Uploader	Upload local images to cloud hosting (sm.ms) and get public URLs
Cover Generator	Generate gradient-based cover images (1200x630) with custom title, subtitle, and theme
Auto Blog Cover	End-to-end blog cover automation: parse markdown frontmatter, generate cover, upload, and update fields
Session Export	Export AI chat sessions to readable Markdown files with optional summarization
Agent Notifier	Multi-channel notifications (sound, macOS alert, Telegram, Email, Slack, Discord) when your AI agent needs input or finishes a task

Installation

Skills CLI (Recommended)

Install all skills at once using the Skills CLI:

npx skills add crossoverJie/skills

Or install a specific skill:

npx skills add crossoverJie/skills@image-uploader
npx skills add crossoverJie/skills@cover-generator
npx skills add crossoverJie/skills@auto-blog-cover
npx skills add crossoverJie/skills@session-export
npx skills add crossoverJie/skills@agent-notifier

The CLI automatically detects your agent (Claude Code, Codex, Cursor, etc.) and installs to the correct location.

Manual Installation

Claude Code

To make these skills available to Claude Code agents, copy the skills directory to your global configuration folder:

# Create the directory if it doesn't exist
mkdir -p ~/.claude/skills

# Copy skills (assuming you are in the repo root)
cp -r skills/* ~/.claude/skills/

Once installed, Claude will automatically discover these skills when you ask for relevant tasks (e.g., "Upload this image").
