Overview

This skill provides comprehensive cryptocurrency portfolio tracking with:

Real-Time Valuations: Current prices from CoinGecko
Holdings Breakdown: Quantity, value, and allocation per asset
P&L Tracking: Unrealized gains/losses with cost basis
Allocation Analysis: Category breakdown and concentration flags
Multiple Export Formats: Table, JSON, CSV

Key Capabilities:

Track holdings across multiple assets
Calculate portfolio total value in USD
Identify overweight positions (concentration risk)
Export for analysis tools and tax reporting

Prerequisites

Before using this skill, ensure:

Python 3.8+ is installed
requests library is available: pip install requests
Internet connectivity for CoinGecko API access
A portfolio JSON file with your holdings

Portfolio File Format

Create a portfolio file (e.g., holdings.json):

{
  "name": "My Portfolio",
  "holdings": [
    {"coin": "BTC", "quantity": 0.5, "cost_basis": 25000},
    {"coin": "ETH", "quantity": 10, "cost_basis": 2000},
    {"coin": "SOL", "quantity": 100}
  ]
}

Fields:

coin: Symbol (BTC, ETH, etc.) - required
quantity: Amount held - required
cost_basis: Average purchase price per coin (optional, for P&L)
acquired: Date acquired (optional, for records)

Instructions

Step 1: Assess User Intent

Determine what portfolio information the user needs:

Quick check: Total value and top holdings
Holdings list: Full breakdown of all positions
Detailed analysis: Allocations, P&L, risk flags
Export: JSON or CSV for external tools

Step 2: Execute Portfolio Tracking

Run the tracker with appropriate options:

# Quick portfolio summary
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json

# Full holdings breakdown
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --holdings

# Detailed analysis with P&L and allocations
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --detailed

# Export to JSON
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --format json --output portfolio_export.json

# Export to CSV
python {baseDir}/scripts/portfolio_tracker.py --portfolio holdings.json --format csv --output portfolio.csv

Step 3: Present Results

Format and explain the portfolio data:

Show total portfolio value prominently
Highlight 24h and 7d changes
Explain allocation percentages
Flag any concentration risks
For detailed mode, explain P&L calculations

Command-Line Options

Option	Description	Default
`--portfolio`	Path to portfolio JSON file	Required
`--holdings`	Show all holdings breakdown	false
`--detailed`	Full analysis with P&L	false
`--sort`	Sort by: value, allocation, name, change	value
`--format`	Output format (table, json, csv)	table
`--output`	Output file path	stdout
`--threshold`	Allocation warning threshold	25%
`--verbose`	Enable verbose output	false

Allocation Thresholds

By default, positions > 25% allocation are flagged:

Allocation	Risk Level	Action
< 10%	Low	Normal position
10-25%	Medium	Monitor closely
25-50%	High	Consider rebalancing
> 50%	Very High	Significant concentration risk
