The Design Philosophy

"The user is an AI, not a human. JSON output instead of pretty tables. --help flags instead of UI. Decision trees instead of menus. When your user is an AI, simplicity wins."

— Jake Strait

What It Does

Four CLI scripts, all outputting structured JSON that agents parse directly:

  • live-price — Current price, market cap, volume, 24h change for any coin
  • market-overview — Top coins + global stats (BTC dominance, total market cap)
  • trend-analysis — Historical data with direction detection and volatility scoring
  • coin-compare — Side-by-side metrics with best/worst performer summary

How It Works

Install the skill, then just ask your AI agent:

  • "What's the price of Bitcoin?"
  • "Compare ETH and SOL"
  • "Show me the top 10 coins by market cap"

The agent activates the right script automatically and returns structured data it can act on.

Agent Skills Standard

Built on the Agent Skills open standard — giving AI agents new capabilities through declarative skill files. The agent reads a skill.md file, knows when to activate, and runs the right script automatically.

Build once, works across 20+ AI tools.

Compatibility

Works out of the box with:

Claude Code • Cursor • VS Code Copilot • Gemini CLI • Codex • And 20+ more
