Purpose
This project provides a collection of 18 prompt-based frameworks and analysis templates designed for US stock market evaluation. It integrates with AI platforms and coding environments (like Claude Code, Cursor, and Gemini) to help guide an LLM's financial analysis.

Security Assessment
Overall Risk: Low. The tool primarily consists of Markdown prompt templates rather than executable code. There are no hardcoded secrets, no dangerous permissions requested, and no evidence of arbitrary shell command execution. The only warnings relate to standard file system access found within its automated GitHub Actions workflows (for testing and deployment), which is normal and does not pose a threat to the end user. It functions locally and does not inherently access sensitive user data unless explicitly provided by the user during an LLM session.

Quality Assessment
The project demonstrates strong quality and active maintenance. It is updated frequently, uses the permissive and standard MIT license, and has solid community trust with 30 GitHub stars. Comprehensive documentation, setup guides, and a test suite are provided, indicating a reliable and well-structured open-source project.

Verdict
Safe to use.
