OpenAI Codex CLI is Lightweight coding agent that runs in your terminal
- codexia - Agent workstation for Codex CLI and Claude Code
Agent skills are model-controlled configurations (files, scripts, resources, etc.) that enable Claude Code to perform specialized tasks requiring specific knowledge or capabilities.
- Agents.md - A simple, open format for guiding coding agents, used by over 20k open-source projects.
- Codex Skills - Skills Catalog for Codex
- Codex Skills - Codex Skills by Dimillian
- AgentSys by avifenesh - Workflow automation system for Claude with a group of useful plugins, agents, and skills. Automates task-to-production workflows, PR management, code cleanup, performance investigation, drift detection, and multi-agent code review. Includes agnix for linting agent configurations. Built on thousands of lines of code with thousands of tests. Uses deterministic detection (regex, AST) with LLM judgment for efficiency. Used on many production systems.
- AI Agent, AI Spy by Whittaker & Tiwari - Members from the Signal Foundation with some really great tips and tricks on how to turn your operating system into an instrument of total surveillance, and why some companies are doing this really awesome thing. [warning: YouTube link].
- cc-devops-skills by akin-ozer - A practical agent skill pack for DevOps work in Claude Code and Codex.
- Claude Codex Settings by fatih akyon - A well-organized, well-written set of plugins covering core developer activities, such as working with common cloud platforms like GitHub, Azure, MongoDB, and popular services such as Tavily, Playwright, and more. Clear, not overly-opinionated, and compatible with a few other providers.
- Scientific Agent Skills by K-Dense - "A set of ready-to-use Agent Skills for research, science, engineering, analysis, finance and writing." That's their description - modest, simple. That's how you can tell this is really one of the best skills repos on GitHub. If you've ever thought about getting a PhD... just read all of these documents instead. Also I think it IS an AI agent or something? Awesome.
- Codex Skill by klaudworks - Enables users to prompt codex from claude code. Unlike the raw codex mcp server, this skill infers parameters such as model, reasoning effort, sandboxing from your prompt or asks you to specify them. It also simplifies continuing prior codex sessions so that codex can continue with the prior context.
- Compound Engineering Plugin by EveryInc - A very pragmatic set of well-designed agents, skills, and commands, built around a discipline of turning past mistakes and errors into lessons and opportunities for future growth and improvement. Good documentation.
- Context Engineering Kit by Vlad Goncharov - Hand-crafted collection of advanced context engineering techniques and patterns with minimal token footprint focused on improving agent result quality.

- read-only-postgres by jawwadfirdousi - Read-only PostgreSQL query skill for Claude Code. Executes SELECT/SHOW/EXPLAIN/WITH queries across configured databases with strict validation, timeouts, and row limits. Supports multiple connections with descriptions for database selection.
- Superpowers by Jesse Vincent - A strong bundle of core competencies for software engineering, with good coverage of a large portion of the SDLC - from planning, reviewing, testing, debugging... Well written, well organized, and adaptable. The author refers to them as "superpowers", but many of them are just consolidating engineering best practices - which sometimes does feel like a superpower when working with Claude Code.
- Trail of Bits Security Skills by Trail of Bits - A very professional collection of over a dozen security-focused skills for code auditing and vulnerability detection. Includes skills for static analysis with CodeQL and Semgrep, variant analysis across codebases, fix verification, and differential code review.
- TÂCHES Claude Code Resources by TÂCHES - A well-balanced, "down-to-Earth" set of sub agents, skills, and commands, that are well-organized, easy to read, and a healthy focus on "meta"-skills/agents, like "skill-auditor", hook creation, etc. - the kind of things you can adapt to your workflow, and not the other way around.
- Web Assets Generator Skill by Alon Wolenitz - Easily generate web assets from Claude Code including favicons, app icons (PWA), and social media meta images (Open Graph) for Facebook, Twitter, WhatsApp, and LinkedIn. Handles image resizing, text-to-image generation, emojis, and provides proper HTML meta tags.
