Load agent skills from the internet temporarily without permanent installation. Works with Kilo, Claude Code, Cursor, Copilot, Windsurf, Gemini, and any agent that supports skills.

Why?

• Try before you install — test any skill for the current session
• No clutter — skills are cached in a temp directory, cleaned up on demand
• No npm install — fetches SKILL.md files directly from GitHub or any URL
• 50 skill limit — prevents context bloat per session
• 100 curated skills — built-in library of top coding & development skills

Install

npm (global CLI)

npm install -g deepfreeze-cli

Then use the deepfreeze command:

deepfreeze load https://github.com/vercel-labs/agent-skills
deepfreeze list
deepfreeze clear

npx (no install)

npx deepfreeze-cli load https://github.com/vercel-labs/agent-skills

Kilo / Claude Code / Cursor / Copilot

Copy the deepfreeze/ directory to your agent's skills folder:

# Kilo
cp -r deepfreeze/ ~/.config/kilo/skills/deepfreeze/

# Claude Code
cp -r deepfreeze/ ~/.claude/skills/deepfreeze/

# Cursor
cp -r deepfreeze/ ~/.cursor/skills/deepfreeze/

# Copilot
cp -r deepfreeze/ ~/.copilot/skills/deepfreeze/

Then say: load temp skill from https://github.com/user/repo

CLI Usage

deepfreeze load <url>     # Load a skill from URL
deepfreeze list           # List loaded temp skills
deepfreeze freeze <name>  # Pin a temp skill (persists across sessions)
deepfreeze unfreeze <name> # Unpin a frozen skill
deepfreeze frozen         # List frozen (pinned) skills
deepfreeze session        # Show session info and skill count
deepfreeze clear          # Remove all temp skills (frozen untouched)
deepfreeze clear --all    # Remove all temp + frozen skills
deepfreeze help           # Show help

Two modes: Temp (auto-cleanup on restart) vs Frozen (persists, protected). Set OPENCLAUDE_SESSION_ID env var for explicit session boundaries.

Examples

# Load from GitHub repo (auto-resolves SKILL.md)
deepfreeze load https://github.com/vercel-labs/agent-skills

# Load from GitHub subfolder
deepfreeze load https://github.com/anthropics/skills/tree/main/pdf

# Load from raw URL
deepfreeze load https://raw.githubusercontent.com/user/repo/main/SKILL.md

# List loaded skills
deepfreeze list

# Clear all
deepfreeze clear

How It Works

1. Fetch — Downloads SKILL.md from GitHub or raw URL via HTTP
2. Validate — Checks for valid frontmatter (name: and description: fields)
3. Cache — Saves to ~/.config/kilo/skills/.temp/<skill-name>/SKILL.md
4. Load — Agent reads the cached file and injects into context
5. Cleanup — User says "clear temp skills" or runs deepfreeze clear

Safety

• Temporary only — never modifies permanent skill directories
• No scripts — only fetches SKILL.md files, no executables
• Max 50 skills — prevents context bloat
• User-initiated — no automatic background fetching

Compatibility

| Tool | Install Method | |---|---| | Kilo | cp deepfreeze/ ~/.config/kilo/skills/ | | Claude Code | cp deepfreeze/ ~/.claude/skills/ | | Cursor | cp deepfreeze/ ~/.cursor/skills/ | | GitHub Copilot | cp deepfreeze/ ~/.copilot/skills/ | | Windsurf | cp deepfreeze/ ~/.windsurf/skills/ | | Gemini CLI | cp deepfreeze/ ~/.gemini/skills/ | | Cline | cp deepfreeze/ ~/.cline/skills/ | | Any agent | Copy deepfreeze/ to the agent's skills directory |
