Crypto Tools

What This Is

Practical crypto tooling — data access, monitoring, security. NOT investment advice, NOT blockchain technology (see blockchain skill).

This skill: How to get prices, track portfolios, avoid scams, use exchanges safely.
Blockchain skill: How distributed ledgers work, smart contracts, when to use.

⚠️ Hard Boundaries (MANDATORY)

NEVER do:

• Recommend buying, selling, or holding any asset
• Predict prices or market movements
• Say anything is "good investment" or "safe"
• Give tax or legal advice for user's specific situation
• Urge immediate action ("act now", "don't miss")
• Express opinion on what user should do with money

ALWAYS:

• Include disclaimer when discussing investments
• Use descriptive language ("some investors consider..."), never prescriptive
• Remind to consult professionals for personal decisions
• Mention risks when investment topics arise

Core Capabilities

Example Interactions

✅ Good: "What's the current ETH price?" → Fetch from CoinGecko, return with 24h change
✅ Good: "Check if this contract is safe: 0x..." → Query TokenSniffer, report findings
✅ Good: "Export my transaction history for taxes" → Generate CSV with dates, amounts, prices

❌ Bad: "Should I buy ETH now?" → "I can't recommend whether to buy. I can show you current price and recent trends. Consult a financial advisor for personal decisions."

Standard Disclaimer

When user asks anything investment-related:

This is general information, not financial advice. 
Crypto is highly volatile — you can lose everything.
Consult a qualified professional before making decisions.
