Description
Query real-time stock prices and market data using the Stock Prices API. Responses are in TOON format—decode with @toon-format/toon. Use when fetching stock...
Usage Guidance
This skill appears coherent and limited to fetching and decoding stock data. Before installing or using it, verify two things: (1) the API host (https://stock-prices.on99.app) — confirm you trust the operator, check HTTPS/TLS and any privacy or rate-limit policies; (2) the npm package @toon-format/toon — inspect the package source, maintainers, and download counts to ensure it's legitimate. If you plan to use this with private or sensitive data, consider whether the API requires/authenticates requests and avoid embedding secrets in plain query strings. If you need guaranteed provenance, prefer an official/known data provider or self-host a vetted decoder implementation.
Capability Analysis
Type: OpenClaw Skill
Name: stock-prices
Version: 1.0.1
The skill is classified as suspicious primarily due to the `pnpm add @toon-format/toon` instruction found in `SKILL.md`. If an AI agent executes this instruction as part of skill setup or execution, it introduces a significant supply chain vulnerability. This allows the agent to install an arbitrary external package, which could lead to arbitrary code execution if the `@toon-format/toon` package (or a typosquatted version) were compromised or malicious. While the stated purpose of the skill (fetching stock prices from `https://stock-prices.on99.app`) appears benign, this capability represents a high-risk action without clear malicious intent from the skill itself, thus classifying it as suspicious rather than malicious.
Capability Assessment
Purpose & Capability
Name/description, API base URL, endpoints, example requests, and decoding instructions all align with a stock-quote retrieval skill. There are no declared env vars, binaries, or config paths that are unrelated to fetching or decoding quotes.
Instruction Scope
SKILL.md only instructs the agent to call the provided HTTPS endpoint and decode the TOON response with an npm package; it does not direct access to unrelated files, environment variables, or external endpoints beyond the described API and the suggested decoder.
Install Mechanism
The skill is instruction-only (no install spec), which is low-risk. It suggests installing @toon-format/toon via pnpm for decoding; this is reasonable for the stated purpose but is an external package so verify its provenance before installing in environments with strict supply-chain requirements.
Credentials
The skill requests no environment variables, credentials, or config paths. This is proportionate to a public-stock-quote fetcher that does not advertise authenticated endpoints.
Persistence & Privilege
The skill does not request persistent/always-on privilege and uses default invocation settings. It does not instruct modifying other skills or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install stock-prices - After installation, invoke the skill by name or use
/stock-prices - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.1
- Responses are now provided in TOON (Token-Oriented Object Notation) format instead of JSON, saving ~40% tokens.
- Added instructions for decoding TOON responses using the @toon-format/toon package.
- Updated sample code and usage sections to demonstrate decoding and handling TOON data.
- Clarified that all API consumers must decode responses before use.
v1.0.0
Initial release of the stock-prices skill.
- Query real-time stock prices and market data using the Stock Prices API.
- Fetch quotes for individual or multiple ticker symbols (e.g., AAPL, NVDA, GOOGL).
- Supports common fields including current price, daily change, high/low, pre-market data, and more.
- Provides typical usage examples for price monitoring, portfolio tracking, and market summaries.
- Allows up to 50 symbols per request; all prices in USD and timestamps in ISO 8601 (UTC).
