Deepfreeze

Deepfreeze

Load skills from the internet without installing them permanently. Skills are cached in a session-scoped temp directory and cleaned up on demand.

CRITICAL: Temporary Only — Never Install

This skill exists to PREVENT permanent installation. You MUST:

• NEVER run npx skills add, npx skills install, or any install command
• NEVER copy files into ~/.config/kilo/skills/ or ~/.kilocode/skills/ (outside .temp/)
• NEVER modify package.json, .skill-lock.json, or any config to register a skill
• NEVER suggest the user permanently install a skill you fetched temporarily
• If the temp loading fails, report the error — do NOT fall back to permanent installation

ALL skills — including those from the Default Skill Library below — are temporary. They go into .temp/, they load into context for the current session, and they get cleaned up. Nothing persists permanently.

Session Limit: Max 50 Skills

A maximum of 50 temp skills can be loaded per session. Before fetching a new skill:

1. Count existing skills in .temp/ directory
2. If count >= 50, refuse and tell the user: "Session limit reached (50 temp skills). Say 'clear temp skills' to free up slots, then try again."
3. If count

### Manual Cleanup

```bash
deepfreeze clear         # Remove all temp skills (frozen skills untouched)
deepfreeze clear --all   # Remove ALL skills (temp + frozen)

Deep Freeze: Pin Skills Across Sessions

Frozen skills persist across sessions and are protected from auto-cleanup. Use this for skills you always want available.

Commands

deepfreeze freeze      # Pin a temp skill → moves to .frozen/
deepfreeze unfreeze    # Unpin → returns to .temp/ (auto-cleanup again)
deepfreeze frozen            # List all frozen (pinned) skills

When to Freeze

• Freeze a skill when you want it available in every session without re-fetching
• Unfreeze when you no longer need it pinned, or want to update it
• Frozen skills are not counted toward the 50 temp skill limit

Example Workflow

deepfreeze load https://github.com/user/repo    # Load as temp
deepfreeze freeze pdf                            # Pin it
deepfreeze frozen                                # Confirm it's frozen
# ... session ends, new session starts ...
deepfreeze list                                  # Temp is empty (auto-cleared)
deepfreeze frozen                                # 'pdf' still here!
deepfreeze unfreeze pdf                          # Return to temp when done

For Agent Developers

When the user says "freeze this skill" or "pin this skill", run:

deepfreeze freeze 

When they say "unfreeze" or "unpin":

deepfreeze unfreeze 

Quick Start

User: load temp skill from https://github.com/vercel-labs/agent-skills
Agent: Fetches, caches, and loads the skill for this session.

Supported URL formats:

• GitHub repo: https://github.com/user/repo → fetches SKILL.md from repo root
• GitHub subfolder: https://github.com/user/repo/tree/main/path → fetches SKILL.md from that path
• Raw URL: https://example.com/SKILL.md → fetches directly
• Raw GitHub: https://raw.githubusercontent.com/... → fetches directly

URL Resolution

When the user provides a URL, resolve it to a raw SKILL.md URL using these rules:

1. GitHub blob URL (github.com/user/repo or github.com/user/repo/tree/branch/path):

• Extract user, repo, branch (default: main), and path (default: root)
• Convert to: https://raw.githubusercontent.com/{user}/{repo}/{branch}/{path}/SKILL.md
• If the path already ends with .md, use it as-is (don't append /SKILL.md)

1. Raw GitHub URL (raw.githubusercontent.com/...):

• Use as-is

1. Any other HTTP(S) URL:

• Use as-is (must point to SKILL.md content)

Resolution Examples

| Input | Resolved URL | |---|---| | https://github.com/vercel-labs/agent-skills | https://raw.githubusercontent.com/vercel-labs/agent-skills/main/SKILL.md | | https://github.com/user/repo/tree/dev/skills/my-skill | https://raw.githubusercontent.com/user/repo/dev/skills/my-skill/SKILL.md | | https://raw.githubusercontent.com/user/repo/main/SKILL.md | https://raw.githubusercontent.com/user/repo/main/SKILL.md | | https://example.com/my-skill.md | https://example.com/my-skill.md |

Fetching & Caching

Step 0: Check Session Limit

Before fetching, count existing temp skills:

# On Windows (PowerShell)
$count = (Get-ChildItem "$HOME\.config\kilo\skills\.temp" -Directory -ErrorAction SilentlyContinue).Count
if ($count -ge 50) { Write-Host "LIMIT REACHED: $count/50 temp skills loaded. Run 'clear temp skills' to free slots." }

# On macOS/Linux
count=$(ls -d ~/.config/kilo/skills/.temp/*/ 2>/dev/null | wc -l)
if [ "$count" -ge 50 ]; then echo "LIMIT REACHED: $count/50 temp skills loaded. Run 'clear temp skills' to free slots."; fi

If limit reached, STOP and inform the user. Do NOT fetch.

Step 1: Check Cache First

Before fetching, check if the .temp directory exists and create it if needed:

# On Windows (PowerShell)
New-Item -ItemType Directory -Path "$HOME\.config\kilo\skills\.temp" -Force

# On macOS/Linux
mkdir -p ~/.config/kilo/skills/.temp

Use the appropriate command for the current platform. The bash tool abstracts this — just run the command.

Step 2: Fetch the SKILL.md Content

Use the webfetch tool with the resolved URL:

webfetch(url=resolved_url, format="text")

Step 3: Validate the Content

The fetched content MUST contain valid SKILL.md frontmatter. Check for:

• Starts with ---
• Contains name: field
• Contains description: field
• Ends the frontmatter block with ---

If validation fails, report the error to the user and stop.

Step 4: Extract Skill Name

Parse the name: field from the frontmatter. This becomes the cache directory name.

Step 5: Save to Cache

# On Windows (PowerShell)
$skillDir = "$HOME\.config\kilo\skills\.temp\{skill-name}"
New-Item -ItemType Directory -Path $skillDir -Force
Set-Content -Path "$skillDir\SKILL.md" -Value $fetchedContent

# On macOS/Linux
mkdir -p ~/.config/kilo/skills/.temp/{skill-name}
echo "$fetchedContent" > ~/.config/kilo/skills/.temp/{skill-name}/SKILL.md

Replace {skill-name} with the actual name extracted from frontmatter. Use the Write tool if available, otherwise use platform-appropriate shell command.

Loading into Context

After saving the skill to cache, load it into the conversation context.

Method 1: Skill Tool (Preferred)

Try loading via the Skill tool using the full path:

Skill(name="$HOME\.config\kilo\skills\.temp\{skill-name}\SKILL.md")

If this works, the skill is now available in context.

Method 2: Direct Read (Fallback)

If the Skill tool cannot resolve the temp path, read the file directly:

Read(filePath="$HOME\.config\kilo\skills\.temp\{skill-name}\SKILL.md")

Then inject the content as context in your response. The skill instructions will be available for the current conversation.

Confirmation

After loading, confirm to the user: "Loaded temp skill '{skill-name}' from {url}. It's now available for this session."

Cleanup

When the user says "clear temp skills", "cleanup temp skills", or "remove temp skills":

Step 1: List Cached Skills

# On Windows (PowerShell)
Get-ChildItem "$HOME\.config\kilo\skills\.temp" -Directory -ErrorAction SilentlyContinue | Select-Object Name

# On macOS/Linux
ls -la ~/.config/kilo/skills/.temp/ 2>/dev/null

If the .temp directory doesn't exist or is empty, inform the user: "No temp skills to clean up."

Step 2: Delete the Temp Directory

# On Windows (PowerShell)
Remove-Item "$HOME\.config\kilo\skills\.temp" -Recurse -Force -ErrorAction SilentlyContinue

# On macOS/Linux
rm -rf ~/.config/kilo/skills/.temp

Step 3: Confirm Cleanup

"Cleared all temp skills from cache."

Error Handling

| Error | Response | |---|---| | Invalid URL format | "The URL doesn't appear to be valid. Please provide a GitHub repo URL or a direct link to a SKILL.md file." | | Fetch fails (404) | "Could not find a skill at that URL. Please check the URL and try again." | | Fetch fails (network) | "Network error while fetching the skill. Please check your connection and try again." | | No frontmatter in response | "The content at that URL doesn't appear to be a valid SKILL.md file (missing frontmatter)." | | Missing name: field | Use the last path segment of the URL as the skill name. Inform the user: "No skill name found in frontmatter, using '{segment}' as the name." | | Skill name conflicts with installed skill | Warn the user: "A skill named '{name}' is already installed. The temp version will be loaded instead for this session." |

Default Skill Library

100 coding & development skills from the open agent skills ecosystem. All loaded TEMPORARILY — never installed permanently. Max 50 per session.
