Academic Research Skills for Claude Code

Skills for Real Engineers is an open-source collection of small, composable agent skills by Matt Pocock for disciplined software development with Claude Code, Codex, and other coding agents. The skills support requirements clarification, project-language setup, test-driven development, debugging, code review, specification, planning, triage, and codebase surveys. The collection includes skills such as `/grill-me` and `/grill-with-docs`, which question the user about a proposed change before implementation, and a setup skill that configures an issue tracker, ticket labels, and documentation storage for a repository. It can be installed as a managed Claude Code plugin or copied into a project as editable files through the `skills` installer; the skills are intended to work with any model and can be adapted by the user.

Everything Claude Code is a Claude Code plugin and toolkit containing configurable agents, skills, slash commands, rules, hooks, contexts, MCP server configurations, scripts, and tests for AI-assisted software development. Its agents delegate tasks such as planning, code review, security review, testing, and build-error resolution. Skills define workflows including test-driven development, security review, continuous learning, and verification; hooks run on Claude Code tool or session events to load and save context, suggest compaction, and evaluate sessions; and rules provide persistent guidance for security, coding style, testing, Git workflow, delegation, and performance. Node.js scripts support Windows, macOS, and Linux and detect a project's preferred package manager from environment settings, project configuration, package.json, lock files, or global configuration. The repository can be installed as a Claude Code plugin or copied into Claude configuration directories manually. It includes a Node.js test suite and is distributed under the MIT license.

An MIT-licensed Claude Code skill that applies concrete design rules from Refactoring UI by Adam Wathan and Steve Schoger when building or reviewing interfaces. It selects spacing, typography, color, shadow, and radius values from fixed scales; creates hierarchy through font weight and color rather than relying on larger text; and translates subjective issues such as an interface looking "off" into specific mechanical fixes. The repository includes a SKILL.md procedure, references for palette construction, diagnosis, depth, typefaces, grids, and images, plus a contrast-verified starter tokens.css file. Claude Code can load it as a personal or project skill, and it does not include the book's text or images.

Marketing Skills is a collection of Markdown-based skills for AI coding agents, built by Corey Haines. It provides specialized workflows for conversion optimization, copywriting, SEO, analytics, advertising, growth engineering, sales, and related marketing tasks, and supports Claude Code, OpenAI Codex, Cursor, Windsurf, and agents implementing the Agent Skills specification. The skills share context and cross-reference one another. The product-marketing skill serves as the foundation, with other skills consulting it for product, audience, and positioning information before handling tasks such as CRO, copywriting, SEO audits, analytics setup, email flows, pricing, or sales enablement. Skills can be installed individually or as a collection through the Skills CLI, Claude Code's plugin system, a repository clone or submodule, or SkillKit. The repository is built and maintained through community contributions, with issues and pull requests welcomed. It is free and MIT-licensed.
