name: send-secret version: 0.0.1 description: This skill should be used when the user asks to "share a secret", "send secret", "share credentials", "share password", "share securely", "encrypted sharing", "one-time secret link", "self-destructing message", "secure file transfer", or mentions "send-secret" without specifying file/clipboard/receive. Routes to the appropriate specialized skill based on context. allowed-tools: Bash(npx send-secret*)

Send Secret - Secure P2P Sharing

send-secret enables zero-trust, one-time encrypted sharing. Secrets are encrypted locally with AES-256-GCM and served via temporary Cloudflare tunnels. The decryption key stays in the URL fragment (never sent to servers).

Quick Reference

Routing Logic

1. User provides a file path

→ Use send-secret-file skill

Example triggers:

• "Send my .env file securely"
• "Share credentials.json with teammate"
• "Encrypt and send this config file"

2. User mentions clipboard

→ Use send-secret-clipboard skill (macOS only)

Example triggers:

• "Share what I copied"
• "Send my clipboard securely"
• "I copied a password, share it"

3. User provides a trycloudflare URL

→ Use receive-secret skill

URL pattern: https://*.trycloudflare.com/s/*#key=*

Example triggers:

• "Get this secret: https://xyz.trycloudflare.com/s/abc#key=..."
• "Download from this link"
• "Receive this encrypted file"

4. User is vague

→ Ask for clarification

Example response: "I can help you share secrets securely. What would you like to share?

• A file (I'll need the file path)
• Something in your clipboard (copy it first, then I'll send it)
• Or do you have a link to receive a secret from?"

Security Principles

Critical for all send-secret operations:

1. Never read secret content - Agent handles paths/URLs only
2. Never display received secrets - Always save to file with -o
3. Never commit secrets - Remind users about .gitignore
4. Never pipe content through agent - Use direct file paths or pbpaste |

CLI Quick Reference

Copy# Send a file
npx send-secret <filepath>

# Send clipboard (macOS)
pbpaste | npx send-secret

# Receive to file
npx send-secret -r "<url>" -o ./filename.txt

# Options
-n <count>    # Allow multiple views
-t <seconds>  # Auto-expire timeout
-o <file>     # Output path for receiving

Common Workflows

Onboarding new team member

1. User: "I need to share our API keys with the new dev"
2. Clarify: File or clipboard?
3. If file: npx send-secret ./api-keys.env
4. Share URL, remind to keep terminal open

Receiving shared credentials

1. User provides trycloudflare URL
2. Use receive-secret skill
3. npx send-secret -r "<url>" -o ./credentials.txt
4. Remind about .gitignore

Quick password share

1. User: "Share my copied password"
2. Confirm they've copied it
3. pbpaste | npx send-secret -t 120
4. Share URL with timeout info
