Add ask-crypto skill (Velvet Unicorn /ask)

[postmachines]

Summary

Adds a new ask-crypto skill that integrates Velvet Unicorn’s /ask endpoint to provide AI-powered crypto intelligence within the agentic wallet ecosystem.

What it does

Enables agents to:

• Answer natural-language crypto questions (e.g., “What do you think about Base?”)
• Analyze tokens and protocols (fundamentals, narrative, risk, momentum)
• Analyze EVM wallets (exposure, positioning, activity patterns)
• Provide market outlook and trade commentary
• Return optional proposed transaction data (txdata) for downstream execution skills

This skill is informational and read-only. It does not execute, sign, or broadcast transactions.

What is Velvet Unicorn?

Velvet Unicorn is an AI-powered crypto intelligence engine developed by VelvetDAO. It processes natural-language crypto queries and returns structured responses including categorized analysis and optional transaction intent data.

Endpoint used:

https://gentweet.velvetdao.xyz/ask

Response structure:

• meta_category
• vu_category
• answer
• txdata (proposal only)

How it works

The skill sends a POST request to the Velvet /ask endpoint with:

{
  "question": "...",
  "context": "...",
  "userid": "0x...",
  "userid_sol": "",
  "previous_questions": []
}

The agent:

• Returns the answer directly to the user
• Treats txdata as proposed transaction data only
• Requires explicit user confirmation before passing any intent to execution skills (e.g., trade or send)

Safety Model

• Read-only skill
• No signing or transaction broadcasting
• No automatic execution of txdata
• Explicit user confirmation required before any downstream execution

Example Use Cases

• “What do you think about Base right now?”
• “Analyze this wallet: 0xabc…”
• “Should I rotate from UNI into ARB?”
• “Summarize risk and momentum for OP vs ARB”
