Install in OpenClaw
/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 only if you are comfortable sending crypto token lookup requests to CoinGecko and Hyperliquid and having temporary chart/cache files written under /tmp. For shared or multi-user hosts, prefer a hardened version that uses a private temp/cache directory and pinned dependencies.
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
Credentials
Network calls to public market-data APIs and writing PNG/JSON files under /tmp are proportionate to the skill's purpose and disclosed, though predictable /tmp filenames create a local cache-poisoning or symlink-risk hardening gap.
Install Mechanism
Installation is ordinary skill installation plus matplotlib; the dependency is lower-bounded rather than pinned, which is a reproducibility and supply-chain hygiene issue but not evidence of malicious behavior.
Instruction Scope
Activation language is broad for crypto price and market-data requests, but it remains within the advertised crypto price/chart domain and does not instruct the agent to change goals, bypass policy, or run unrelated tasks.
Persistence & Privilege
The only persistence found is a documented 300-second cache and generated chart images in /tmp; there are no startup hooks, background workers, credential stores, memory writes, or privilege-escalation behavior.
Purpose & Capability
The stated purpose is cryptocurrency price lookup and candlestick chart generation, and the script behavior matches that purpose using CoinGecko and Hyperliquid APIs.
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
