For each one: copy everything in that GitHub folder into ~/.claude/skills/<name>/ (make the folders if needed; if a folder of that name already exists, ask me before replacing it). Use git or download the files, whichever works on this computer.
Each link points at the exact version Launch7 checked — install that version, not a newer one.
Do not run any scripts from the skills while installing them.
When you're done, list what you installed and remind me to start a new Claude Code session so the skills load.

(From my Launch7 stack: https://launch7.in/stacks/spreadsheets-and-data/)

    Works on Windows, macOS and Linux. Your AI asks before it runs anything.

  2. Start a new Claude Code session. Each skill is used when a task matches it — you don’t have to name it.

For macOS, Linux, or Git Bash on Windows.

All 6 in one download. Every skill’s whole folder, scripts included, to copy into ~/.claude/skills. Steps inside.

launch7-spreadsheets-and-data-for-claude-code.zip

Packed in your browser straight from GitHub — nothing passes through Launch7.

Every link in the message points at the version Launch7 checked, where the skill’s page says it is pinned. Launch7 has not run these end to end.
