通过 Yahoo Finance 获取全球多市场股票、指数、外汇及加密货币的历史行情、财务数据、实时报价和财务日历。
Usage Guidance
This skill is broadly coherent with a data-pipeline/backtest helper, but has several practical mismatches you should be aware of before installing or running it:
- The skill will check for and may ask you to install Python packages (zvt) and initialize a data directory (~/.zvt). Only proceed if you trust the upstream packages and are comfortable the agent may run pip or shell commands.
- SKILL.md reads the ZVT_HOME environment variable and expects provider API tokens (joinquant, etc.) though none are declared in the registry metadata. Do not provide sensitive API keys without verifying the skill's source and license. Prefer creating minimal-permission keys or sandbox accounts for testing.
- The skill references an unfamiliar 'uv' package manager; verify what that is (and its trustworthiness) before installing or allowing any automatic install steps.
- Evidence-quality notes in SKILL.md warn that only ~30% of evidence was verified and show audit failures — treat generated results as potentially incomplete and validate critical outputs against authoritative sources.
- Practical steps: ask the publisher/source (there is none listed) for a homepage or upstream repo; verify the LICENSE and the zvt package versions it intends to use; set ZVT_HOME to a writable directory you control; run any install steps in a disposable environment (virtualenv/containers) first; and avoid pasting high-privilege credentials into prompts until you confirm the skill's provenance.
If the publisher/source is provided and the skill's metadata is updated to declare the environment requirements (ZVT_HOME, provider tokens) and explain the 'uv' manager, my confidence that this is benign would increase.
Capability Analysis
Type: OpenClaw Skill
Name: yfinance-market-data
Version: 0.3.3
This skill bundle provides a highly structured framework for financial market data retrieval and backtesting, primarily utilizing the `zvt` library and Yahoo Finance. The instructions for the AI agent (found in `SKILL.md` and `seed.yaml`) are focused on enforcing financial logic and data integrity, such as 'Semantic Locks' to prevent look-ahead bias (`SL-02`) and 'Constraints' to ensure proper HTTP session management (`finance-C-001`). There is no evidence of data exfiltration, malicious code execution, or harmful prompt injection; the bundle's complexity is dedicated to preventing common quantitative trading errors and ensuring compliance with market-specific rules like A-share T+1 trading.

Capability Assessment
Purpose & Capability
Name/description focus on Yahoo Finance data, and the content does implement multi-market data-sourcing and ZVT-based pipelines (historical prices, streaming, screeners). However the SKILL.md also references many other providers and a full ZVT pipeline (recorders, traders, backtest), so actual capabilities are broader than the simple name implies. This breadth is plausible for a market-data skill but is larger than a minimal 'yfinance' fetcher.
Instruction Scope
The SKILL.md contains explicit runtime preconditions that run python -c checks, read ZVT_HOME, instruct pip installs (on precondition failures), and require re-loading seed.yaml before decisions. These are file/OS interactions and package-install actions not declared in the registry metadata. The instructions thus direct the agent to read env vars and modify the runtime environment (install packages, initialize ~/.zvt), which is beyond a simple API-caller scope and should be expected and consented to by the user.
Install Mechanism
There is no formal install spec (instruction-only), which reduces automated install risk. However SKILL.md demands 'Python 3.12+ with uv package manager' and the seed.yaml execution_protocol instructs running host install recipes and import checks — implicit install steps may be executed by the agent or user. The ambiguous dependency on an unfamiliar 'uv' package manager is unusual and worth verifying.
Credentials
Registry metadata lists no required env vars, but the instructions explicitly read ZVT_HOME and expect data-source API tokens for some providers (joinquant, etc.) per the constraints. The skill expects access to filesystem locations (~/.zvt) and may prompt for provider tokens, yet does not declare those credentials. This mismatch (undeclared env access and credential expectations) reduces transparency and could lead to unintentional exposure of secrets or filesystem changes.
Persistence & Privilege
always is false and the skill is not marked to be force-included. The SKILL.md does instruct initialization of ZVT directories and running preconditions, but it does not request persistent global privileges or modify other skills. No evidence of attempts to alter other skills' configs or enable permanent autonomous presence.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install yfinance-market-data - After installation, invoke the skill by name or use
/yfinance-market-data - Provide required inputs per the skill's parameter spec and get structured output
