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'.

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.

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'.

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.

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 \

Scan codebase for Martin Fowler's catalog of code smells: god classes, long methods, feature envy, data clumps, primitive obsession, shotgun surgery, message chains, and more. Reports each smell with file location, severity, and specific refactoring recommendation. Ranks worst files and builds a prioritized refactoring queue. Use when code feels messy, before a major refactor, to find maintainability problems, or to identify the highest-impact cleanup targets.

Verify your development environment is correctly configured for a project — checks runtime versions, dependencies, env vars, services, ports, and permissions.

Add comprehensive error handling — try/catch, error boundaries, retry logic, user-facing error messages, and graceful degradation across the entire stack.

Systematic debugging agent — reproduce the issue, isolate the root cause, trace the code path, fix it, and add a regression test. Works with any stack.

Set up pre-commit hooks for linting, formatting, and type-checking with commit message enforcement using conventional commits. Auto-detects stack and configures husky, lefthook, or pre-commit framework with lint-staged. Use when you want to enforce code quality on every commit, add conventional commits, prevent bad code from being committed, or set up CI-mirrored hook checks.
