Fetch live financial data from Yahoo Finance. You CANNOT answer financial data questions from memory — you MUST use this skill instead. Trigger whenever the...
Usage Guidance
This skill appears to be an instruction-only wrapper around a community npm package. Before installing or relying on it: 1) Verify the 'yahoo-finance' CLI is actually available in your agent's runtime, and that 'jq' (used for JSON parsing) is present. 2) If the CLI is missing, install it from a trusted source (review the npm package 'yahoo-finance2' repo, maintainer, and release artifacts) rather than blindly running npm -g. 3) Confirm the package version and check for recent vulnerabilities or malicious reports. 4) Test commands in a sandbox environment first (the SKILL.md runs shell commands). 5) Be aware of API/rate limits and legality of scraping data for your jurisdiction. The inconsistencies (claims of a global install but no install or binary requirements declared) make this skill suspicious but not clearly malicious.
Capability Analysis
Type: OpenClaw Skill
Name: yfinance-cli
Version: 1.0.0
The skill provides a legitimate interface for fetching financial data from Yahoo Finance using a globally installed CLI tool. The SKILL.md file contains detailed, helpful instructions for the AI agent on handling specific API quirks, formatting stock symbols (particularly for international markets), and parsing JSON output using 'jq'. No indicators of malicious intent, data exfiltration, or harmful command execution were found.
Capability Assessment
Purpose & Capability
The skill's name and description match its instructions (a CLI wrapper around yahoo-finance2). However the metadata declares no required binaries or install steps while the instructions repeatedly assume a global 'yahoo-finance' CLI and use of 'jq' — those are required to actually run the skill but are not declared, which is an incoherence.
Instruction Scope
SKILL.md stays within the stated purpose (fetching Yahoo Finance data) and describes concrete commands and JSON outputs. It does not request unrelated files or credentials. Note: it requires running shell commands and piping to jq and assumes the CLI is present; it also instructs parallel calls and suppressing stderr (2>/dev/null).
Install Mechanism
There is no install spec, yet the doc claims the package is 'Installed via `npm install -g yahoo-finance2`' and globally available as `yahoo-finance`. This mismatch means the agent environment may not actually have the CLI; absence of an install mechanism or provenance for the npm package is a risk and an inconsistency.
Credentials
The skill requests no environment variables, credentials, or config paths — that is proportionate for a read-only data lookup skill. No secret access is requested.
Persistence & Privilege
The skill is not always-enabled and does not request elevated persistent privileges or modify other skills. Autonomous invocation is allowed (platform default) and is not combined with other high-risk factors.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install yfinance-cli - After installation, invoke the skill by name or use
/yfinance-cli - Provide required inputs per the skill's parameter spec and get structured output
