agent-skills: a set by addyosmani

code-review-and-quality addyosmani skill Five review axes and a limit on diff size, so an agent checks a change before merge instead of after. Claude Code CX Codex Cursor +1 72,500installs security-and-hardening addyosmani skill Guides threat modeling and security checks for code that handles user input, authentication, sessions, or external services. Use it when building a feature that accepts untrusted data or reviewing code before release. Claude Code CX Codex Cursor +1 69,400installs frontend-ui-engineering addyosmani skill Enforces production standards for component architecture, WCAG 2.1 AA accessibility, and design systems. Stops AI models from defaulting to purple buttons, heavy shadows, and arbitrary spacing. Claude Code CX Codex Cursor +1 66,600installs performance-optimization addyosmani skill An agent skill that measures before it changes code: Core Web Vitals budgets, N+1 queries, missing indexes and slow endpoints. Claude Code CX Codex Cursor +1 64,500installs spec-driven-development addyosmani skill Enforces writing a structured specification before coding. Useful when starting new features, tackling vague requirements, or making architectural decisions. Claude Code CX Codex Cursor +1 64,300installs planning-and-task-breakdown addyosmani skill Breaks specifications into small, testable tasks with clear acceptance criteria. Prevents agents from jumping straight into coding before dependencies and risks are mapped. Claude Code CX Codex Cursor +1 63,600installs documentation-and-adrs addyosmani skill Captures architectural decisions (ADRs) and the context behind code changes. Useful for tracking design choices, API updates, and trade-offs. Claude Code CX Codex Cursor +1 63,200installs code-simplification addyosmani skill Clarifies code and removes unnecessary complexity without altering behavior. Useful when refactoring working features that feel harder to maintain than they should. Claude Code CX Codex Cursor +1 62,200installs debugging-and-error-recovery addyosmani skill This skill guides an agent from reproducing a failure to checking the fix. Use it when tests fail, a build breaks, or runtime behavior differs from expectations. Claude Code CX Codex Cursor +1 62,200installs api-and-interface-design addyosmani skill Guides API and module-boundary design with explicit contracts, validation, and consistent errors. Use it for REST, GraphQL, or public interfaces. Claude Code CX Codex Cursor +1 61,900installs incremental-implementation addyosmani skill Directs agents to deliver code in thin, verified vertical slices instead of bulk edits. Fits multi-file refactoring and feature work behind flags. Claude Code CX Codex Cursor +1 61,300installs test-driven-development addyosmani skill This skill guides work through red-green-refactor: write a failing test, add the smallest passing code, then refactor. Use it for logic, bugs, and behavior changes. Claude Code CX Codex Cursor +1 61,300installs context-engineering addyosmani skill Helps you set up agent context: which rules, specs and files to feed the agent, and when. Use it at the start of a session, when output quality drops, or when switching tasks. Claude Code CX Codex Cursor +1 60,900installs git-workflow-and-versioning addyosmani skill A skill that sets git discipline for coding agents: atomic commits, short-lived branches, worktrees for parallel work. Useful when the agent commits faster than you review. Claude Code CX Codex Cursor +1 58,900installs idea-refine addyosmani skill Turns raw concepts into sharp, actionable plans through structured divergence and stress-testing. Creates a concise MVP one-pager. Claude Code CX Codex Cursor +1 58,600installs using-agent-skills addyosmani skill A meta-skill that tells the agent which skill from the agent-skills collection fits the task in front of it, and which behaviour rules apply all the time. Claude Code CX Codex Cursor +1 58,500installs browser-testing-with-devtools addyosmani skill Connects your coding agent to Chrome via DevTools MCP. Helps inspect the live DOM, catch console errors, check network payloads, and visually verify UI fixes. Claude Code CX Codex Cursor +1 57,900installs shipping-and-launch addyosmani skill Walks your agent through a production launch: pre-launch checklist, monitoring, staged rollout and a rollback plan. Useful when a feature reaches real users. Claude Code CX Codex Cursor +1 57,800installs source-driven-development addyosmani skill Grounds agent coding decisions in official documentation. It helps verify framework APIs against detected versions and avoids outdated patterns from model training data. Claude Code CX Codex Cursor +1 57,600installs ci-cd-and-automation addyosmani skill Builds a GitHub Actions CI/CD pipeline for a repo: lint, type check, tests, build and dependency audit chained as gates on every pull request. Claude Code CX Codex Cursor +1 57,500installs deprecation-and-migration addyosmani skill Guides the retirement of old systems, APIs, and features and moves users to a replacement. It also covers production database migrations without downtime. Claude Code CX Codex Cursor +1 56,800installs interview-me addyosmani skill Conducts a one-question-at-a-time interview to extract actual project intent before any code or specs. Useful when a task is underspecified. Claude Code CX Codex Cursor +1 56,700installs doubt-driven-development addyosmani skill This skill sends non-trivial decisions to a fresh-context reviewer looking for flaws. Use it before changes that are hard to undo or costly to debug later. Claude Code CX Codex Cursor +1 56,100installs observability-and-instrumentation addyosmani skill Instruments code with structured logs, RED and USE metrics, and distributed tracing. Use it when shipping features to production so issues are diagnosable. Claude Code CX Codex Cursor +1 54,200installs constraint-driven-development addyosmani skill Turns a project's quality bar into CONSTRAINTS.md with real numbers, then watches the diff for weakened checks and deleted tests.
