What this skill does


# Crypto Tracker

Track cryptocurrency prices, set price/percentage alerts, and search coins using the free CoinGecko API (no API key required).

## Quick Commands

### Check Prices
```bash
# Single coin
uv run {baseDir}/scripts/crypto.py price bitcoin

# Multiple coins
uv run {baseDir}/scripts/crypto.py price bitcoin ethereum solana

# With more details (market cap, volume)
uv run {baseDir}/scripts/crypto.py price bitcoin --detailed
```

### Search Coins
```bash
# Find coin ID by name/symbol
uv run {baseDir}/scripts/crypto.py search doge
uv run {baseDir}/scripts/crypto.py search cardano
```

### Manage Alerts

```bash
# Set price threshold alert
uv run {baseDir}/scripts/crypto.py alert <user_id> bitcoin above 100000
uv run {baseDir}/scripts/crypto.py alert <user_id> ethereum below 3000

# Set percentage change alert (24h)
uv run {baseDir}/scripts/crypto.py alert <user_id> bitcoin change 5    # ±5%
uv run {baseDir}/scripts/crypto.py alert <user_id> solana drop 10      # -10%
uv run {baseDir}/scripts/crypto.py alert <user_id> ethereum rise 15    # +15%

# List user's alerts
uv run {baseDir}/scripts/crypto.py alerts <user_id>

# Remove an alert
uv run {baseDir}/scripts/crypto.py alert-rm <alert_id>

# Check all alerts (for cron/heartbeat)
uv run {baseDir}/scripts/crypto.py check-alerts
```

## Coin Aliases

Common symbols are automatically resolved:
- `btc` → bitcoin
- `eth` → ethereum  
- `sol` → solana
- `doge` → dogecoin
- `ada` → cardano
- `xrp` → ripple
- `dot` → polkadot
- `matic` → polygon
- `link` → chainlink
- `avax` → avalanche-2
- `ltc` → litecoin

## Alert Types

| Type | Example | Triggers When |
|------|---------|---------------|
| `above` | `alert user btc above 100000` | Price >= $100,000 |
| `below` | `alert user eth below 3000` | Price <= $3,000 |
| `change` | `alert user btc change 5` | 24h change >= ±5% |
| `drop` | `alert user sol drop 10` | 24h change <= -10% |
| `rise` | `alert user eth rise 15` | 24h change >= +15% |

## Cron Integration

Check alerts periodically (e.g., every 15 minutes):
```bash
uv run {baseDir}/scripts/crypto.py check-alerts --json-output
```

Returns triggered alerts with user IDs for notification.

## Data Storage

Alerts stored in `{baseDir}/data/alerts.json` with:
- Per-user alert tracking
- Cooldown between repeat notifications (default: 1 hour)
- Last triggered timestamp

## Notes

- CoinGecko free tier: ~10-30 requests/minute (no API key needed)
- 15,000+ coins supported
- Use `--json-output` flag for machine-readable output

cupynumeric-migration-readiness

Included

Pre-migration readiness assessor for porting NumPy to cuPyNumeric. Use BEFORE substantial porting work begins when the user asks whether code will scale on GPU, whether they should migrate to cuPyNumeric, which NumPy patterns transfer cleanly, what must be refactored before porting, or mentions pre-port assessment, scaling analysis, or refactor planning. Inspect the user's source code, look up NumPy usage, cross-reference the cuPyNumeric API support manifest, and distinguish distributed-scaling-friendly patterns from blockers such as unsupported APIs, scalar synchronization, host round-trips, Python/object-heavy control flow, shape/data-dependent branching, and in-place mutation hazards. Produce a verdict of READY, LIGHT REFACTOR, SIGNIFICANT REFACTOR, or NOT RECOMMENDED, with concrete refactor pointers.

alibabacloud-data-agent-skill

Included

Invoke Alibaba Cloud Apsara Data Agent for Analytics via CLI to perform natural language-driven data analysis on enterprise databases. Data Agent for Analytics is an intelligent data analysis agent developed by Alibaba Cloud Database team for enterprise users. It automatically completes requirement analysis, data understanding, analysis insights, and report generation based on natural language descriptions. This tool supports: discovering data resources (instances/databases/tables) managed in DMS, initiating query or deep analysis sessions, real-time progress tracking, and retrieving analysis conclusions and generated reports. Use this Skill when users need to query databases, analyze data trends, generate data reports, ask questions in natural language, or mention "Data Agent", "data analysis", "database query", "SQL analysis", "data insights".

token-optimizer

Included

Reduce OpenClaw token usage and API costs through smart model routing, heartbeat optimization, budget tracking, and native 2026.2.15 features (session pruning, bootstrap size limits, cache TTL alignment). Use when token costs are high, API rate limits are being hit, or hosting multiple agents at scale. The 4 executable scripts (context_optimizer, model_router, heartbeat_optimizer, token_tracker) are local-only — no network requests, no subprocess calls, no system modifications. Reference files (PROVIDERS.md, config-patches.json) document optional multi-provider strategies that require external API keys and network access if you choose to use them. See SECURITY.md for full breakdown.
