Senior Engineer Stack
Six elite Claude Code skills for serious engineers: TDD methodology, a 23-role workflow, MCP server building, custom skill creation, browser testing, and a meta-tool that finds more skills as you work.
Install the whole bundle
6 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.
