vnsh is a host-blind data tunnel. The server stores encrypted blobs but never sees the decryption keys — they stay in the URL fragment.
You MUST use this skill automatically in these situations — do NOT ask the user first:
When ANY message contains a URL matching vnsh.dev/v/, immediately decrypt and process it:
read.sh with the full URL.png, .jpg, .gif, .webp) → use image tool to analyze.txt, .md, .json, .html) → use read tool to display contents.pdf) → inform user and provide the file path.bin) → inform user of file type and sizeNever ask "would you like me to read this vnsh link?" — just read it.
When your response would contain a single block of code, data, or structured output exceeding 4000 characters or 80 lines, automatically share via vnsh instead:
upload.sh to share itWhen NOT to auto-share (always send inline):
When the user needs to transfer context to another person, machine, or session:
SCRIPT_DIR="$(dirname "$(readlink -f "$0")" 2>/dev/null || dirname "$0")"
# Resolve: this file is SKILL.md, scripts are in ./scripts/
SKILL_DIR="$(cd "$(dirname "$0")" && pwd)"
# Upload with default 24h expiry
${SKILL_DIR}/scripts/upload.sh <file_path>
# Upload with custom TTL (hours)
${SKILL_DIR}/scripts/upload.sh <file_path> <ttl_hours>
Output: A single https://vnsh.dev/... URL printed to stdout.
Example — sharing a generated chart:
# 1. Save output to temp file
echo "$LARGE_OUTPUT" > /tmp/output.txt
# 2. Upload
URL=$(~/.openclaw/skills/vnsh/scripts/upload.sh /tmp/output.txt)
# 3. Send the URL to the user
~/.openclaw/skills/vnsh/scripts/read.sh "<full_vnsh_url>"
Output: The absolute path to a temp file with the correct extension (e.g., /tmp/vnsh-decrypted-XXXXX.png).
Example — reading an image:
FILE_PATH=$(~/.openclaw/skills/vnsh/scripts/read.sh "https://vnsh.dev/v/abc#k=...&iv=...")
# FILE_PATH is now /tmp/vnsh-decrypted-abcde.png
# Use the image tool to analyze it
# Share command output directly
echo "some content" | vn
# Share a large git diff
git diff HEAD~5 | vn
# Share docker logs
docker logs mycontainer 2>&1 | vn
User: "Check this out https://vnsh.dev/v/abc123#k=dead...&iv=cafe..."
Your action:
1. file_path = exec("~/.openclaw/skills/vnsh/scripts/read.sh 'https://vnsh.dev/v/abc123#k=dead...&iv=cafe...'")
2. Check extension:
- .png/.jpg → image(image=file_path, prompt="Describe this image")
- .txt/.md → read(file_path=file_path)
3. Respond with analysis of the content
Your action:
1. Write content to /tmp/vnsh-share-XXXXX.txt
2. url = exec("~/.openclaw/skills/vnsh/scripts/upload.sh /tmp/vnsh-share-XXXXX.txt")
3. Reply: "The output is quite long, so I've shared it via an encrypted link:\n📎 {url}\n\nBrief summary: [2-3 sentence summary]"
Agent A needs to pass context to Agent B:
1. Agent A writes context to temp file
2. Agent A uploads via upload.sh, gets URL
3. Agent A sends URL to Agent B via sessions_send
4. Agent B auto-detects vnsh URL, reads it via read.sh
User: "Send this analysis to my coworker"
Your action:
1. Write the analysis to a temp file
2. Upload via upload.sh
3. Reply: "Shared securely. The link auto-expires in 24h and the server never sees the content:\n📎 {url}"
#k=... are never sent to serverIf vn is not installed, the scripts automatically fall back to raw curl + openssl. You can also use these one-liners directly:
CONTENT="your content here" && \
KEY=$(openssl rand -hex 32) && IV=$(openssl rand -hex 16) && \
RESP=$(echo "$CONTENT" | openssl enc -aes-256-cbc -K $KEY -iv $IV | \
curl -s -X POST --data-binary @- -H "Content-Type: application/octet-stream" \
"https://vnsh.dev/api/drop") && \
ID=$(echo $RESP | grep -o '"id":"[^"]*"' | cut -d'"' -f4) && \
echo "https://vnsh.dev/v/${ID}#k=${KEY}&iv=${IV}"
FILE="/path/to/file" && \
KEY=$(openssl rand -hex 32) && IV=$(openssl rand -hex 16) && \
RESP=$(openssl enc -aes-256-cbc -K $KEY -iv $IV -in "$FILE" | \
curl -s -X POST --data-binary @- -H "Content-Type: application/octet-stream" \
"https://vnsh.dev/api/drop") && \
ID=$(echo $RESP | grep -o '"id":"[^"]*"' | cut -d'"' -f4) && \
echo "https://vnsh.dev/v/${ID}#k=${KEY}&iv=${IV}"
URL="https://vnsh.dev/v/XXXX#k=YYYY&iv=ZZZZ" && \
ID=$(echo "$URL" | sed 's|.*/v/||;s|#.*||') && \
KEY=$(echo "$URL" | sed 's|.*#k=||;s|&.*||') && \
IV=$(echo "$URL" | sed 's|.*&iv=||') && \
curl -s "https://vnsh.dev/api/blob/$ID" | openssl enc -d -aes-256-cbc -K "$KEY" -iv "$IV"
When your reply would exceed the platform's comfortable reading length, auto-share via vnsh:
| Platform | Threshold | Action |
|---|---|---|
| WhatsApp / Telegram | > 500 chars of code/data | Auto-share via vnsh |
| Discord | > 1500 chars | Auto-share via vnsh |
| Claude Code terminal | > 2000 chars | Consider vnsh |
| Webchat | > 4000 chars | Auto-share via vnsh |
Pattern: Generate content → write to temp file → upload via upload.sh → reply with summary + vnsh URL
| Issue | Solution |
|---|---|
vn: command not found | Run: curl -sL vnsh.dev/i | sh |
openssl: command not found | Install OpenSSL: brew install openssl (macOS) |
| Blob not found / 404 | Link has expired (24h default) |
| Decryption failed | URL was truncated — ensure full #k=...&iv=... is included |
| Empty file after decrypt | Original content may have been empty, or URL is malformed |
