Best Claude skills for debugging in 2026

Zero to power user in one invoke — detects OS, installs Homebrew/apt/Node.js/Python, sets up Claude Code, authenticates skills-hub CLI, connects MCP servers, and installs recommended skills based on your project. Cross-platform (macOS, Linux, WSL). Idempotent. Use when: 'quickstart', 'setup machine', 'new machine setup', 'install everything', 'get started', 'onboard me', 'setup skills-hub', 'fresh install'.

Scan a codebase for broken links — dead URLs in Markdown/HTML, broken file references, invalid import paths, stale anchor links, and broken cross-doc references — then auto-fix what it can: replace dead URLs with Wayback Machine archives, update moved file paths via git history, remove anchors that no longer exist, and flag what needs human review. Self-healing: learns fix patterns and improves over iterations. Use when: 'fix broken links', 'check links', 'dead links', 'broken urls', 'link rot', 'fix references', 'validate links', 'stale links', 'broken imports'.

Pre-deploy verification gate. Checks git status, build, tests, migrations, secrets, and commit conventions. Reports READY or NOT READY. Read-only, no changes. Trigger words: preflight, pre-deploy check, ready to deploy, deployment checklist.

Set up a single powerful Mac as your entire software company infrastructure — self-hosted CI/CD runners, Remotion video rendering, local LLMs for privacy tasks, TTS inference, and Docker services. Eliminate cloud costs and run everything locally. Use when setting up a local dev server, replacing GitHub Actions with self-hosted runners, configuring Ollama for local AI, building a video pipeline with Remotion and TTS, or optimizing a Mac Studio/Ultra for concurrent workloads.

A comprehensive social media automation skill that monitors platforms like Reddit and other social media sites to generate, post, and reply with relevant content promoting your app. It ensures content relevance, adheres to platform policies, and incorporates best practices for engagement and safety.

Monitor and maintain CI runner health — check disk space, clear stale caches (Flutter, Gradle, npm, Docker), prune old worktrees, and report status. Prevents cache corruption failures.

A comprehensive, automated code quality analysis tool that performs static analysis across multiple programming languages, identifies issues, security vulnerabilities, code smells, and duplications, and generates detailed, actionable reports to improve code \

Analyze game balance by extracting stats from code and running mathematical simulations. Calculates DPS tier lists, TTK matrices, EHP comparisons, and character power rankings. Stress-tests economy earn/spend rates, progression XP curves, and unlock pacing. Runs Monte Carlo simulations on drop rates, loot tables, and crafting RNG. Use when tuning weapon damage, checking if characters are overpowered, validating economy pacing, auditing gacha fairness, or testing PvP matchup balance.

Cross-repo morning briefing -- recent commits, PR status, CI health, blockers, and suggested priorities for today. Use when: 'morning standup', 'what happened yesterday', 'daily briefing', 'repo status', 'what should I work on today', 'standup report', 'team update', 'cross-repo summary', 'CI health check'.
