JavaScript loadouts

These loadouts cover JavaScript work where there is no compiler to catch mistakes: Chrome extensions under Manifest V3, with minimal permissions and a skill for getting through Chrome Web Store review; a launch check that catches leaked keys, open databases and missing auth before your app goes live; and Playwright tests that drive a real Electron app and fail if its security settings slip.

Every one installs for Claude Code, Codex CLI, Cursor, Gemini CLI, Antigravity CLI and GitHub Copilot unless its card says otherwise.
