Personal Codex Skills

This repository collects the Codex skills I use across machines. It is designed to be cloned into a normal Git workspace and then synced into the local Codex skills directory.

Skills

Skill	What it does
arxiv2md	Converts arXiv papers into clean Markdown through the online arxiv2md REST API, then runs a local cleanup pass for common conversion artifacts.
global-stock-value-analysis	Investigates company operations through public sources and connects the evidence to equity valuation across US, China A-share, HK, and global markets.

Each skill folder is self-contained and can be copied into a Codex skills directory.

Agent Conventions

This repository includes an AGENTS.md file for Codex/agent behavior. The main convention is:

• Use uv for Python installation, virtual environments, dependency resolution, script execution, and package management.

Install Or Sync On Windows

Clone this repository, then run:

.\scripts\sync-to-codex.ps1

By default the script syncs these skill folders to:

$env:USERPROFILE\.codex\skills

To sync somewhere else:

.\scripts\sync-to-codex.ps1 -Destination "D:\path\to\.codex\skills"

The sync replaces only the matching skill folders in the destination. Other skills in the destination are left untouched.

Manual Install

Copy the desired folders into your Codex skills directory:

%USERPROFILE%\.codex\skills\arxiv2md
%USERPROFILE%\.codex\skills\global-stock-value-analysis

Restart Codex or reload skills after copying.

Notes

• arxiv2md is intentionally trimmed to the skill instructions, cleanup script, and license. It uses the public arxiv2md.org API rather than vendoring the upstream service project.
• global-stock-value-analysis routes from SKILL.md to focused references. Its operating research workflow investigates products, customers, suppliers, competitors, industry data, and project/regulatory records alongside financial reports. It includes asset/depreciation checks for capital-intensive businesses and requires evidence when judging whether a profit or cash-flow scenario is achievable.
• These skills are research and workflow helpers. The stock analysis skill is not personalized financial advice.

License

Unless a skill folder contains its own license file, the contents are published under the repository license. The arxiv2md folder includes its own MIT license.
