Description
Monitor live cryptocurrency prices, technical indicators, and support/resistance levels with customizable price alerts and portfolio summaries.
README (SKILL.md)
Crypto Price Alerter
Fetch live cryptocurrency prices and technical indicators via CoinGecko free API.
Quick Usage
uv run python scripts/price_check.py --symbol BTC --currency USD
uv run python scripts/price_check.py --symbol ETH --currency USD --upper 4000 --lower 2000
uv run python scripts/price_check.py --symbol SOL --currency USD --output json
Core Features
- Current Price — Live price, 24h change %, 24h volume, market cap
- Technical Indicators — SMA(7), SMA(21), RSI(14) from 30-day historical data
- Key Levels — 30-day resistance and support
- Price Alerts — Triggered when 24h change >5% or price crosses user thresholds
- JSON output — For automation pipelines:
--output json
Scripts
scripts/price_check.py— Main script. Run standalone withuv run python scripts/price_check.py [args]
Arguments
| Arg | Description |
|---|---|
--symbol |
Crypto symbol (e.g. BTC, ETH, SOL) — required |
--currency |
Fiat currency (default: USD) |
--upper |
Upper price threshold for alert |
--lower |
Lower price threshold for alert |
--days |
Historical days for SMA (default: 30) |
--output |
text (default) or json |
Technical Signals
See references/signals.md for explanation of SMA, RSI, support/resistance, and trading signal interpretation.
Alert Logic
- 24h change > +5% → Bullish alert
- 24h change \x3C -5% → Bearish alert
- Price >=
--upperthreshold → Price ceiling alert - Price \x3C=
--lowerthreshold → Price floor alert
Usage Guidance
This skill appears to do what it claims: it queries CoinGecko and computes simple indicators, with no credential requests. Before installing or running it: (1) inspect and fix the bundled script — there is a likely string/quote formatting error in build_report that will cause a Python syntax error, so the script may not run as-is; (2) ensure the runtime has Python and the 'requests' package installed; (3) run it in a sandbox or controlled environment (no secrets) and verify network access is restricted to only the CoinGecko endpoints if you require that; (4) be aware CoinGecko is rate-limited and responses can change — consider adding error/rate-limit handling if you rely on it for alerts; (5) no credentials are needed, so do not add API keys unless you intentionally extend the skill and understand the implications.
Capability Analysis
Type: OpenClaw Skill
Name: crypto-price-alerter
Version: 1.0.0
The crypto-price-alerter skill is a standard utility for fetching and analyzing cryptocurrency data from the CoinGecko API. The Python script (scripts/price_check.py) uses legitimate API endpoints, handles network requests safely using the requests library, and performs local mathematical calculations for technical indicators like SMA and RSI. There is no evidence of data exfiltration, unauthorized file access, or malicious prompt injection in the documentation (SKILL.md).
Capability Tags
Capability Assessment
Purpose & Capability
Name/description match the provided script: the code queries CoinGecko endpoints and computes SMA/RSI/support-resistance and alerts. No unrelated services, binaries, or credentials are requested.
Instruction Scope
SKILL.md only instructs running the included script and describes expected args/outputs. It does not ask the agent to read unrelated files, access secrets, or transmit data to unknown endpoints; all network calls are to CoinGecko public APIs.
Install Mechanism
No install spec is provided (instruction-only with a bundled script). This means nothing is downloaded or written during install. Note: the script depends on the 'requests' library (not declared), so ensure runtime has that dependency.
Credentials
No environment variables, credentials, or config paths are requested. The skill does not attempt to read secrets or unrelated system config — access requests are proportional to the stated purpose.
Persistence & Privilege
The skill does not request always:true or any elevated persistence. Model invocation is allowed by default but that's normal; nothing in the skill tries to modify other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install crypto-price-alerter - After installation, invoke the skill by name or use
/crypto-price-alerter - Provide required inputs per the skill's parameter spec and get structured output
