Best Claude skills for performance in 2026

A comprehensive autonomous web research agent that performs targeted searches, fetches and parses web content, summarizes findings, and generates structured reports, adhering to industry best practices for accuracy, security, and robustness.

Reconstructs the development cycle from git history, distills sequential/parallel patterns, and produces actionable insights for improving future iterations. Triggers: recall, retrospective, development analysis, what happened, dev cycle analysis.

Analyze frontend bundle size, detect heavy dependencies, find duplicates, evaluate tree-shaking, recommend code splitting, and generate size budget configs. USE THIS SKILL WHEN: user mentions bundle size, JavaScript bundle, webpack analysis, slow page load from large bundles, tree-shaking, code splitting, heavy dependencies, duplicate packages, vendor chunk, DIM weight of JS, or performance budget. Trigger phrases: "analyze bundle size", "why is my bundle so big", "find heavy dependencies", "reduce bundle size", "code splitting opportunities", "tree-shaking not working", "duplicate packages in bundle", "set up size budget", "vendor chunk too large", "initial load too slow", "optimize webpack output", "vite build analysis".

Analyzes mobile app binary size -- asset audit for unused images and font subsetting, code stripping with ProGuard and tree-shaking, on-demand resources, dynamic feature modules, and app thinning strategies. USE THIS SKILL WHEN: - Your app's download size is too large or growing unexpectedly - Someone asks "why is our app so big?" or "how do we reduce app size?" - You need to audit assets (images, fonts, videos) for waste or optimization - App store reviewers flag your app for exceeding cellular download limits (200MB) - You want to check if ProGuard/R8, tree-shaking, or resource shrinking is properly configured - Someone mentions ABI splits, dynamic feature modules, or on-demand resources - You are preparing for a release and want to minimize download size - Users are complaining about storage space or download times - You need to audit dependencies for size bloat or lighter alternatives TRIGGER PHRASES: "app size", "binary size", "reduce app size", "APK size", "IPA size", "unused ass

Autonomous SEO + AI-search optimization agent for 2026. Audits and fixes technical SEO, on-page metadata, structured data, Core Web Vitals (LCP/INP/CLS), llms.txt, Generative Engine Optimization (GEO) for ChatGPT/Perplexity/AI Overviews, E-E-A-T author signals, programmatic SEO for catalog sites, and AI-crawler config. Reports findings + applies fixes.

Audits and implements mandatory image resizing and compression for all uploaded user images to reduce storage costs while preserving visual quality.

Generate MLS-compliant property listing copy in five length variants (tagline, MLS-short ≤250 char, MLS-long ≤4000 char, marketing description ~600-800 words, social caption) PLUS schema.org RealEstateListing JSON-LD for SEO/AEO syndication. Auto-runs HUD Fair Housing Act compliance check (catches discriminatory language patterns — "perfect for families", "walking distance", "exclusive", "safe neighborhood", "Christian community", etc.). TRIGGER on phrases like "MLS listing", "property listing description", "listing copy", "real estate description", "Zillow listing", "compelling listing", "write the listing", "MLS remarks", "marketing copy for [property]", "open house copy". Saves agents 30-60 minutes per listing — and prevents the fair-housing violations that cost agents licenses.

Add rate limiting to APIs — configure per-user and per-IP limits, sliding window algorithms, tiered quotas, retry-after headers, and progressive abuse detection.

Analyze project dependencies for health, security, and bloat — audit outdated, deprecated, vulnerable, duplicate, heavy, and unused packages across npm, pip, cargo, go mod, and more. Produce a dependency health score, CVE inventory, license compatibility matrix, bundle size impact assessment, and a prioritized update plan with migration paths.

Analyzes asset lifecycle planning systems for capital expenditure forecasting, replacement scheduling, total cost of ownership modeling, depreciation tracking, and facility condition assessments using IFMA standards and Facility Condition Index scoring. USE THIS SKILL WHEN: - You are reviewing facilities management or asset management software - Someone asks about capital planning, replacement scheduling, or deferred maintenance - You need to evaluate Facility Condition Index (FCI) calculations or condition assessments - A project involves total cost of ownership (TCO) or life cycle cost analysis (LCCA) - You are auditing an asset registry, CMDB, or equipment database - Someone mentions Maximo, SAP EAM, Archibus, TRIRIGA, or similar platforms - You need to assess depreciation tracking or fixed asset register accuracy - A facility portfolio has growing deferred maintenance or declining FCI scores - Capital budget requests need data-driven prioritization TRIGGER PHRASES: "asset lifecycle
