Description
Fetch real-time and historical financial data from Yahoo Finance using yf-cli. Use when the user asks about stock prices, company financials, earnings calend...
Usage Guidance
This skill is internally consistent: it uses the yf-cli tool to get Yahoo Finance data and does not ask for secrets. Before installing, ensure you trust the provenance of the external tools it invokes (uv and yf-cli) and that your environment allows network access. If you are concerned about autonomous invocation, note the skill can run yf-cli commands when invoked by the agent — consider restricting autonomous use or reviewing logs. If you need stronger guarantees, verify the sources for uv and yf-cli (package repositories/releases) and inspect the yf-cli code you will install.
Capability Analysis
Type: OpenClaw Skill Name: yf-finance Version: 1.0.0 The yf-finance skill bundle is a legitimate tool for fetching financial data from Yahoo Finance using the yf-cli utility. It contains standard installation procedures via the 'uv' package manager in scripts/install.sh and SKILL.md, and provides comprehensive documentation for various financial queries. No indicators of data exfiltration, malicious execution, or prompt injection were found; the included Python snippets in assets/examples.md are strictly for data processing.
Capability Assessment
Purpose & Capability
Name/description match the behavior: SKILL.md instructs running yf-cli to fetch quotes, history, financials, news, etc. No unrelated binaries or credentials are requested.
Instruction Scope
Runtime instructions only call yf-cli and (in examples) simple one-liner Python processing; they do not reference unrelated files, secrets, or external endpoints beyond normal network access to fetch Yahoo Finance data.
Install Mechanism
No install spec in the registry; the included install.sh only checks for yf and runs `uv tool install yf-cli` if missing. This is a low-risk, expected install pattern (no opaque downloads or extracted archives in the skill).
Credentials
The skill requires no environment variables, credentials, or config paths. Its stated requirements (Python 3.13+, uv, yf-cli) are reasonable for running the described CLI tool.
Persistence & Privilege
always is false and the skill does not request persistent system-wide configuration or elevated privileges. The small install script only invokes uv and yf and does not modify other skills or agent configuration.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install yf-finance
  3. After installation, invoke the skill by name or use /yf-finance
  4. Provide required inputs per the skill's parameter spec and get structured output
