Overview
Track cryptocurrency holdings with real-time CoinGecko valuations, allocation analysis, P&L tracking, and concentration risk alerts.
Prerequisites
- Python 3.8+ installed
- Dependencies:
pip install requests - Internet connectivity for CoinGecko API access
- A portfolio JSON file with your holdings (see
references/implementation.mdfor format)
Instructions
-
Assess user intent - determine what portfolio view is needed:
- 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
-
Run the portfolio tracker with appropriate options:
# Quick portfolio summary python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json # Full holdings breakdown python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json --holdings # Detailed analysis with P&L and allocations python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json --detailed -
Export results for analysis tools or tax reporting:
python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json --format json --output portfolio_export.json python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json --format csv --output portfolio.csv -
Present results to the user:
- Show total portfolio value prominently
- Highlight 24h and 7d changes
- Explain allocation percentages
- Flag any concentration risks (positions > 25% allocation by default)
Output
Summary showing total value, 24h/7d changes, per-asset allocation, and concentration warnings for positions exceeding threshold:

Error Handling
| Error | Cause | Solution |
|---|---|---|
| Portfolio file not found | Invalid path | Check file path exists |
| Invalid JSON | Malformed file | Validate JSON syntax |
| Coin not found | Unknown symbol | Check symbol spelling, use standard symbols |
| API rate limited | Too many requests | Wait and retry, use caching |
See ${CLAUDE_SKILL_DIR}/references/errors.md for comprehensive error handling.
Examples
Portfolio tracking workflows from quick checks to detailed analysis and export:
# Basic portfolio check
python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio ~/crypto/holdings.json
# All holdings sorted by allocation
python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json --holdings --sort allocation
# Detailed analysis with custom 15% threshold
python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json --detailed --threshold 15
# Export for tax software
python ${CLAUDE_SKILL_DIR}/scripts/portfolio_tracker.py --portfolio holdings.json --format csv --output tax_export.csv

Expert guidance for Next.js Cache Components and Partial Prerendering (PPR). **PROACTIVE ACTIVATION**: Use this skill automatically when working in Next.js projects that have `cacheComponents: true` in their next.config.ts/next.config.js. When this config is detected, proactively apply Cache Components patterns and best practices to all React Server Component implementations. **DETECTION**: At the start of a session in a Next.js project, check for `cacheComponents: true` in next.config. If enabled, this skill's patterns should guide all component authoring, data fetching, and caching decisions. **USE CASES**: Implementing 'use cache' directive, configuring cache lifetimes with cacheLife(), tagging cached data with cacheTag(), invalidating caches with updateTag()/revalidateTag(), optimizing static vs dynamic content boundaries, debugging cache issues, and reviewing Cache Component implementations.
