The Claude Code Plugin Power-Up Sheet — The 10 Most-Installed Plugins, Ranked by Anthropic's Own Install Data (With What Each One Costs Your Context)
The companion to the full video where every plugin on this list was installed and run on a real machine — nothing quoted from a README. Claude Code downloads a public statistics feed and prints an install count beside every plugin in /plugin → Discover; this sheet is that ranking, current to July 3, 2026, with the measured cost of each one. INSIDE: (1) THE RANKING — all ten with exact install counts: frontend-design (1,017,241), superpowers (913,876), code-review (404,331), context7 (392,837), skill-creator (347,481), code-simplifier (325,031), github (297,738), playwright (293,416), claude-md-management (264,540), feature-dev (242,535) — plus the five just outside the top ten. (2) WHAT THEY ACTUALLY DO, read from the installed source: the skill that names the three looks AI design defaults to and forbids them; the review command that runs five parallel reviewers and then deletes any finding scored under 80 for confidence before you ever see it; the agent that rewrites your code and refuses to say 'done' without proof; the plugin that audits your CLAUDE.md against the codebase as it exists today. (3) THE COST, MEASURED with claude plugin details — every always-on number, the ~1,100-token total for all ten, and the numbers that actually matter: what a skill pulls in when it fires (skill-creator ~8,200, superpowers' subagent skill ~6,900). (4) THE GOTCHA — the top-ten plugin that installs perfectly, reports no error, and never connects until you set GITHUB_PERSONAL_ACCESS_TOKEN, with the exact fix and how to verify it. (5) INSTALL MECHANICS — the one-line install command, the four-plugin starter set, all three install scopes (user / project / local), removal, marketplace refresh, and Claude Code's own verbatim trust warning about what Anthropic does and does not control in plugins. Install counts are Anthropic's published plugin statistics as of July 3, 2026; token costs measured on Claude Code v2.1.219 on July 25, 2026.
