Description
Fetch recent finance news headlines for stock, ETF, and index symbols via Yahoo Finance (yfinance), with caching and structured JSON output.
Usage Guidance
This skill appears to be what it says: a small Python script that uses yfinance to fetch Yahoo Finance news, caches results locally, and outputs JSON. Before installing, note: (1) it will make outbound network requests to Yahoo via the yfinance library (no other external endpoints are present), (2) it creates and writes to .cache/finance-news in the skill directory, and (3) you need to install the yfinance dependency (recommended inside a virtualenv). If you are concerned about network activity, run it in an isolated environment or review the script (scripts/market_news.py) — it is short and straightforward. No credentials are requested and nothing in the skill appears disproportionate or unrelated to its purpose.
Capability Analysis
Type: OpenClaw Skill
Name: yahoofinance-news
Version: 1.0.1
The skill bundle is a legitimate tool for fetching financial news headlines using the yfinance library. The Python script (scripts/market_news.py) implements standard caching and data normalization logic, and the SKILL.md instructions correctly guide the agent on how to install dependencies and execute the script without any signs of malicious intent or prompt injection.
Capability Assessment
Purpose & Capability
Name/description match the actual files and runtime behavior. The script uses yfinance to fetch news, requires python3 and yfinance (requirements.txt), and creates a local cache directory (.cache/finance-news) which is declared in SKILL.md metadata. There are no unrelated binaries or credentials requested.
Instruction Scope
SKILL.md instructs the agent to install dependencies in a venv and run the included Python script per symbol, parse JSON, and present headlines with URLs. The instructions do not ask the agent to read unrelated files, access other credentials, or transmit data to unexpected endpoints. The skill will perform network calls via yfinance to fetch Yahoo data and write cache files under the declared cache directory.
Install Mechanism
This is instruction-only with a small code file and a requirements.txt containing only yfinance. There is no download-from-URL or archive extraction; installation is the normal pip install of a single dependency. No high-risk install mechanics are present.
Credentials
The skill requires only python3 and the yfinance package; it requests no environment variables, credentials, or config paths beyond a local cache directory. The absence of secrets or unrelated env vars is proportionate to its function.
Persistence & Privilege
The skill does not require always:true and does not request elevated privileges. It writes cache files under .cache/finance-news in the skill directory (matching SKILL.md metadata). It does not modify other skills or system-wide agent configuration.
How to Use
