Every Coding Skill in the Pack

Each runs from one command inside Claude Code. Open a skill for the details, or view it on GitHub.

Brainstorming

Enforces a design-first gate before any implementation. Explores intent, proposes 2–3 approaches with tradeoffs, writes a spec doc for approval, then transitions to code.

DESIGNPLANNINGSPECIFICATION

Code Review

Automated code review across TypeScript, Python, Go, Rust, and 11 more languages. Analyzes PRs for complexity, flags SOLID violations, and scores code quality with Approve/Block verdicts.

Works best with GitHub, GitLab

>/codingkarpathy-guidelines

Karpathy Guidelines

Behavioral guidelines to reduce common LLM coding mistakes, derived from Andrej Karpathy's observations. Four rules: think first, simplicity, surgical changes, and goal-driven execution.

Frequently Asked Questions

Everything you need to know about installing and running these Claude Skills.

Claude Skills for coding are open-source slash commands for Claude Code that turn common software engineering workflows into one-command tasks. The pack covers design-first brainstorming, automated code review across 14+ languages, TDD enforcement, deep PR analysis, architecture diagramming, and Karpathy's coding guidelines, each running inside Claude Code with no dashboards or logins.
Claude Code is Anthropic's CLI tool for running AI-powered commands in your terminal. You need Claude Code installed to use these coding skills. Once the repo is cloned into your project, you run any skill by name, like /coding code-reviewer or /coding senior-architect.
Yes. Every coding skill is open source and free to use, hosted on GitHub and updated regularly. You can read each skill's prompt, fork it, and adapt it to your own codebase, team conventions, and engineering workflows.
They span the full development workflow: design-first specification with brainstorming, automated multi-language code review with scoring, deep pull request analysis with blast radius and security checks, TDD enforcement with Red-Green-Refactor, architecture diagramming and dependency analysis, and Karpathy's behavioral guidelines against common LLM coding mistakes.
Clone the repo into your project, open Claude Code, and type the skill by name, for example /coding brainstorming to design a feature before implementing it, or /coding code-reviewer to review a pull request. Most skills need no setup; skills that integrate with GitHub or GitLab use the respective CLI tools if installed.
The Brainstorming skill enforces a design-first gate: before any code is written, Claude explores your project context, asks clarifying questions, proposes 2–3 approaches with tradeoffs, writes a spec doc, and self-reviews it for contradictions and ambiguity. Only after you approve the spec does implementation begin. It prevents the most common mistake in AI-assisted coding: jumping to implementation without a clear design.
The Iron Law is: no production code can be written until a failing test for that code exists and has been observed failing. The TDD skill enforces this absolutely, walks you through the Red-Green-Refactor cycle, dismantles every common rationalization for skipping the test-first step, and requires a verification checklist before marking any work complete.
Most coding skills run on Claude Code alone with no external dependencies. The PR Review Expert and Code Reviewer skills can use the GitHub CLI (gh) or GitLab CLI (glab) if installed and authenticated to fetch PR diffs and CI status, but they also work on local git diffs without those tools.
The Karpathy Guidelines are four behavioral rules derived from Andrej Karpathy's observations on how LLMs commonly fail at coding tasks: think before coding, simplicity first, surgical changes, and goal-driven execution. They're for any developer using Claude Code for production work who wants to avoid over-engineering, unnecessary scope, and unverified implementation.
Yes, and they're designed to complement each other. A typical workflow might use brainstorming to design a feature, senior-architect to validate the technical approach, test-driven-development to implement it, and then code-reviewer or pr-review-expert to review the final diff before merging.
