Description
Free stock and crypto momentum scanner with social sentiment analysis. Scans S&P 500, Nasdaq 100, and crypto for momentum signals using RSI, EMA, Bollinger S...
Usage Guidance
Key things to consider before installing:
- The README/SKILL.md claim "No API keys required," but the bundled script can use a TAVILY_API_KEY to query a third-party (Tavily) for Reddit sentiment. That credential is not declared in the skill metadata — only provide it if you trust the Tavily service and the skill's author.
- If you do NOT set TAVILY_API_KEY, Reddit sentiment calls will silently be disabled (the code returns None), but StockTwits and yfinance calls will still make outbound network requests.
- The skill writes data to ~/.openclaw/workspace/memory/ripe_scanner and /tmp; snapshots may include symbol lists and scraped social results. Review those files if you run the skill.
- Source/homepage are unknown — consider reviewing the full script locally (scripts/ripe-scan.py) for any additional network endpoints or unexpected behavior before running.
- If you want to be cautious: run the skill in a sandboxed environment or network-restricted container, or remove/inspect the Tavily call before use. If you need safer behavior, ask the author to declare TAVILY_API_KEY in metadata and document when it will be used.
Capability Analysis
Type: OpenClaw Skill
Name: ripe-scanner
Version: 1.1.0
The ripe-scanner skill is a legitimate financial analysis tool designed to scan stocks and cryptocurrencies for momentum signals. The Python script (scripts/ripe-scan.py) uses standard libraries like yfinance, pandas, and numpy to calculate technical indicators and fetches social sentiment data from StockTwits and Tavily (for Reddit search). The code logic is transparent, follows the functionality described in SKILL.md and README.md, and stores data locally within the designated OpenClaw workspace. No evidence of data exfiltration, malicious execution, or prompt injection was found.

Capability Assessment
Purpose & Capability
Name/description (momentum + social sentiment scanner) aligns with the code's behavior (yfinance technicals, StockTwits, Reddit). However SKILL.md and README repeatedly state "No API keys required," yet the script includes logic to call an external Tavily API using TAVILY_API_KEY for Reddit sentiment. That environment secret is not declared in the skill metadata and contradicts the 'no API keys' claim.
Instruction Scope
Runtime instructions tell the agent to run the bundled Python script and save snapshots under ~/.openclaw/workspace/memory/ripe_scanner — that's expected. The script makes external network calls (Wikipedia, yfinance/Yahoo, StockTwits, and optionally Tavily) and writes cache/snapshots to the user's home area. The hidden/undeclared use of a third-party Tavily endpoint for Reddit sentiment expands the instruction scope beyond what's promised and is not surfaced in the SKILL.md metadata.
Install Mechanism
This is effectively an instruction-only skill with an included Python script; there is no package download or install spec beyond asking the user to pip install yfinance,pandas,numpy. No installer URLs or archive extraction are used.
Credentials
Registry metadata declares no required env vars, but the script checks for TAVILY_API_KEY (and will call Tavily if present). That is an undeclared credential requirement. Aside from that, no unrelated credentials (AWS, GCP, tokens) are requested; persistence is limited to files under the OpenClaw workspace and /tmp.
Persistence & Privilege
The skill is not force-included (always:false). It writes snapshots and cache under ~/.openclaw/workspace/memory/ripe_scanner and /tmp which is consistent with its functionality. Autonomous invocation is allowed by default (normal for skills) — nothing in the package requests system-wide changes or other skills' configs.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install ripe-scanner - After installation, invoke the skill by name or use
/ripe-scanner - Provide required inputs per the skill's parameter spec and get structured output
