skills for everythingxlsx
Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like "the xlsx in my downloads") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

My Claude Code Settings
Cross-platform AI content repository with a Rust management workspace.
This repository is organized around two top-level areas:
content/: installable skills, commands, agent definitions, runtime files, and external-skill registry datamcs/: the Rust workspace that powers discovery, install, diff, sync, TUI, and Web workflows
Quick start
git clone https://github.com/bahayonghang/my-claude-code-settings.git
cd my-claude-code-settings
# Terminal UI
just mcs
# Web UI + backend
just web
# Documentation site

The curated third-party registry now lives at content/skills/external-skills/.
Skill categories
The first-party catalog under content/skills/ currently uses these categories:
academic-skillsai-llm-skillsdiagram-skillsdocument-skillsgit-github-skillsmedia-skillsskill-meta-skillstech-stack-skillsworkflow-skills
For the browsable catalog, use the docs site or MCS.
MCS workspace
The Rust workspace in mcs/ currently contains:
mcs-core: shared discovery, metadata, install, path, migration, and prompt logicmcs-tui: ratatui/crossterm terminal UImcs-web: Axum backend plus React frontend hosting
Useful commands:
just mcs
just mcs-dev
just mcs-web
just mcs-web-server
just mcs-web-test
Platform model
Platform paths are defined by:
- built-in defaults in
mcs-core platforms.tomlin this repository- optional user overrides in
~/.config/myclaude/platforms.toml
Not every platform has its own independent source tree. For example, commands may install from a fallback source directory even if the target platform installs them to a different folder.
Documentation
The VitePress site in docs/ covers:
- installation
- MCS TUI
- MCS Web
- MCS architecture
- commands
- runtime files
- external skills
- skill catalog pages in English and Chinese
For the Codex CLI skill specifically, see docs/skills/ai-llm-skills/codex.md and docs/zh/skills/ai-llm-skills/codex.md. Those pages track the current Codex CLI syntax and now document the gpt-5.4 default model plus the recommended codex exec / live web-search patterns.
Direct skill-only install
To install all skills non-interactively to specific agents (Universal, Antigravity, Claude Code, iFlow CLI, Kiro CLI, Qwen Code, Trae, Trae CN):
npx skills add bahayonghang/my-claude-code-settings/content/skills --skill '*' -g -y -a universal -a antigravity -a claude-code -a iflow-cli -a kiro-cli -a qwen-code -a trae -a trae-cn
If you only want the first-party skill catalog and do not need the full repository workflow:
npx skills add bahayonghang/my-claude-code-settings/content/skills
