Crypto Price Alerter

Monitor live cryptocurrency prices, technical indicators, and support/resistance levels with customizable price alerts and portfolio summaries.

Security Scan

The skill's code, instructions, and requirements align with its stated purpose (fetching crypto prices and computing simple indicators); it uses only public CoinGecko endpoints and requests, asks for no credentials, and has no install steps — but the bundled script contains a likely syntax/formatting bug and minor implementation roughness you should review before running.

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.

Assessment

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.

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

1. Current Price — Live price, 24h change %, 24h volume, market cap
2. Technical Indicators — SMA(7), SMA(21), RSI(14) from 30-day historical data
3. Key Levels — 30-day resistance and support
4. Price Alerts — Triggered when 24h change >5% or price crosses user thresholds
5. JSON output — For automation pipelines: --output json

Scripts

• scripts/price_check.py — Main script. Run standalone with uv 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 < -5% → Bearish alert
• Price >= --upper threshold → Price ceiling alert
• Price <= --lower threshold → Price floor alert
