Awesome Claude Skills

Anthropic's repository of Agent Skills for Claude, including example skills, the Agent Skills specification, and a template for creating custom skills. Each skill is a self-contained folder with a SKILL.md file containing metadata and instructions that Claude loads dynamically for specialized tasks such as document creation, data analysis, web-app testing, MCP server generation, and communications workflows. The repository's skills can be installed as Claude Code plugins, used in Claude.ai, or accessed through the Claude API. It includes document, PDF, presentation, and spreadsheet skills used in Claude's document capabilities; many examples are Apache-2.0 licensed, while those document-creation skills are source-available rather than open source. The repository presents the implementations for demonstration and educational purposes and notes that their behavior may differ across Claude environments.

A feature of Anthropic's Claude platform that packages reusable instructions, scripts, and reference files into skills that Claude can apply to specific tasks. Skills can be used in Claude applications and through Anthropic's agent-development tools.

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.

claude-red is a curated library of offensive-security skills for Claude, maintained by SnailSploit. Each skill is a structured SKILL.md file covering a particular attack surface, including web vulnerabilities, identity systems, wireless, cloud, mobile, IoT, exploit development, fuzzing, reconnaissance, API security, containers, cryptography, privilege escalation, post-exploitation, and AI security. The files are intended to be installed into a Claude Skills environment, where matching skills load on demand from conversational triggers, or they can be supplied manually as system files or project prompts. The repository includes an installation script with category and target options, a skill index, a roadmap, contribution guidance, and a review-oriented skill template. It is distributed under the MIT license and lists authorized red-team engagements, bug-bounty triage, security research, CTF preparation, and operator training as use cases.

Academic Research Skills for Claude Code is an open-source suite of Claude Code skills for academic research and publication workflows, maintained by Cheng-I Wu. It provides separate deep-research, academic-paper, academic-paper-reviewer, and academic-pipeline skills for literature reviews, systematic reviews, guided research, drafting, citation conversion, revision, peer review, rebuttal auditing, methodology review, and re-review. The suite uses staged, human-in-the-loop workflows with multi-agent orchestration, Socratic checkpoints, style calibration, writing-quality checks, citation formatting, and outputs in Markdown, DOCX when Pandoc is available, and LaTeX/PDF through tectonic. Its pipeline orchestrator connects activities through ten stages, user-confirmation checkpoints, Material Passport handoffs, claim and citation verification, integrity gates, and final process summaries. Citation verification can cross-check references against Semantic Scholar, OpenAlex, Crossref, and arXiv when available.
