Engineering Essentials
Frontend, API integration, MCP servers, browser testing, and network debugging — the day-to-day software stack.
Install the whole bundle
5 skills into ~/.claude/skills/. Free.
Paste into your terminal. Restart Claude Code afterwards — new skills are picked up on startup.
This copies each skill's full folder (SKILL.md plus any supporting scripts, reference docs, or asset templates) so every skill works out of the box. Safe default.
Faster alternative (instruction-only skills)
Skips the git clone and downloads only each SKILL.md. Avoid if any skill in the bundle ships Python scripts, reference markdowns, or asset templates — they'll be missing and the skill will fail when it tries to load them.
