Install in OpenClaw
/install yahoo-finance
Description
Get stock prices, quotes, fundamentals, earnings, options, dividends, and analyst ratings using Yahoo Finance. Uses yfinance library - no API key required.
Usage Guidance
Before installing, prefer package-manager installation for uv, such as Homebrew or pip, over piping remote installer scripts directly into a shell. Also note that this artifact does not include the referenced yf script, so installation may not provide a working CLI unless the missing script is supplied elsewhere.
Capability Analysis
Type: OpenClaw Skill
Name: yahoo-finance
Version: 1.0.0
The skill bundle is classified as suspicious due to the use of high-risk installation methods for the `uv` package manager, specifically `curl -LsSf https://astral.sh/uv/install.sh | sh` and `powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"` found in `SKILL.md`. While `uv` is a legitimate tool and `astral.sh` is its official domain, these methods involve downloading and executing arbitrary remote scripts, which bypasses package manager integrity checks and presents a significant security risk, even if plausibly needed for the skill's stated purpose. There is no clear evidence of intentional malicious behavior like data exfiltration or persistence.
Capability Assessment
Purpose & Capability
The stated purpose is to fetch stock and market data using Yahoo Finance/yfinance, and the documented commands match that purpose. The artifact contains only SKILL.md and no bundled yf executable, which is a functionality/completeness note rather than a security concern.
Instruction Scope
The runtime instructions are limited to installing prerequisites and running stock-data commands; no prompt override, hidden agent behavior, destructive instruction, or unrelated data access was found.
Install Mechanism
The documentation includes curl-to-shell and PowerShell iex installers for uv, plus safer alternatives such as Homebrew and pip. These are disclosed, user-directed setup options, not automatic execution by the skill.
Credentials
Expected network access is limited to package installation and public finance data retrieval; the artifact says no API key is required and does not request credentials, local profile stores, or sensitive files.
Persistence & Privilege
The skill describes uv dependency caching and an optional symlink into /usr/local/bin, but no background service, privilege escalation, autostart, or unbounded persistence is present.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install yahoo-finance - After installation, invoke the skill by name or use
/yahoo-finance - Provide required inputs per the skill's parameter spec and get structured output
