Automatically analyze Excel data files to generate statistical summaries, detect anomalies, create visual charts, and provide analysis reports and suggestions.

What to consider before installing: - The code performs local analysis only (reads an Excel file, computes stats, detects anomalies, writes a Markdown report). That matches the core description. - The docs advertise chart generation and a chartjs-node-canvas dependency, but neither package.json nor index.js implements charting — the feature appears missing or the docs are out of date. If you need charts, ask the author or inspect/extend the code before relying on it. - SKILL.md contains hidden unicode control characters (prompt-injection signal). Inspect the SKILL.md file in a text editor that can reveal invisible characters; remove them or request a clean copy from the author. - There are no requested credentials or network calls in the code, which limits exfiltration risk, but still run npm install and tests in an isolated sandbox (or CI) before adding to a production agent. - If you plan to use this on sensitive spreadsheets, run it in an isolated environment and review/modify the code to ensure it meets your security and feature requirements. If you need high confidence that nothing external is contacted, search the codebase for network APIs (http/https, child_process, net, fetch) — current files show none.

Type: OpenClaw Skill Name: excel-ai-analyzer Version: 1.0.0 The skill bundle is a legitimate tool for analyzing Excel files and generating Markdown reports. The code in index.js uses the standard 'xlsx' library to perform basic statistical analysis and anomaly detection without any evidence of data exfiltration, malicious execution, or prompt injection. All behaviors align with the stated purpose in SKILL.md and README.md.
