Best Claude Code Plugins for Skills

Audit, usage-track and prune installed skills — token-cost split and a swipe-to-delete TUI

Official collection of Anthropic-built skills for Claude Code. Bundles document skills (pdf, pptx, xlsx, docx), memory maintenance (consolidate-memory), skill authoring (skill-creator), and scheduling — everything you need for day-to-day productivity.

Market-statistics skills that report backtested probabilities with their baselines, sample sizes and p-values: five-class day-type probabilities for the session in progress, Weis volume-price wave events with pre-registered win rates (cib_long 51.8% over a 49.3% baseline, n=13,867), options max pain from open interest alone, and estimated dealer gamma exposure. Publishes where the methods fail — crypto, gold, chart patterns — and refuses to present output as trading advice.
