/install crypto-price
Description
Get cryptocurrency token price and generate candlestick charts via CoinGecko API or Hyperliquid API. Use when user asks for token price, crypto price, price chart, or cryptocurrency market data.
Usage Guidance
Install this if you are comfortable with a skill that runs a local Python script, contacts CoinGecko or Hyperliquid for public market data, and writes temporary cache/chart files in /tmp. Do not treat prices as financial advice, and consider pinning dependencies if you need reproducible installs.
Capability Analysis
Type: OpenClaw Skill
Name: crypto-price
Version: 0.2.2
The OpenClaw AgentSkills skill bundle is benign. The `SKILL.md` file contains instructions for the AI agent on how to format its output to display charts (`MEDIA: <chart_path>`), which is a functional prompt injection aligned with the skill's purpose and not malicious. The `get_price_chart.py` script interacts with legitimate cryptocurrency APIs (CoinGecko, Hyperliquid), uses standard Python libraries, and stores temporary cache and chart files in the `/tmp` directory. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or obfuscation. All network calls are to known public endpoints, and the `matplotlib` dependency is standard for plotting.
Capability Assessment
Purpose & Capability
The stated purpose is cryptocurrency price lookup and candlestick chart generation, and the artifacts consistently implement that through CoinGecko/Hyperliquid API calls, JSON output, and PNG chart creation.
Instruction Scope
The skill instructs the agent to run a bundled Python script and emit a MEDIA line for the generated chart; this is a formatting/control instruction, but it is disclosed and necessary for the chart-attachment workflow.
Install Mechanism
Installation requires Python 3 and matplotlib via requirements.txt; matplotlib is a normal charting dependency, though the dependency is version-bounded rather than exactly pinned.
Credentials
Outbound requests to CoinGecko and Hyperliquid and writes under /tmp are disclosed and proportionate to fetching prices, caching public data, and saving generated charts.
Persistence & Privilege
The only persistence found is a 5-minute /tmp cache and generated PNG files; there are no startup hooks, background workers, credential/session access, privilege escalation, or destructive file operations.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install crypto-price - After installation, invoke the skill by name or use
/crypto-price - Provide required inputs per the skill's parameter spec and get structured output
