Outskill

A two-day, hands-on AI workshop from Outskill covering AI tools, agent building, workflow automation, and image and video generation. The program is advertised as including more than 16 hours of instruction with expert mentors and access to more than 10 AI tools.

Rival Workshop is a downloadable kit of 150 editable instruction files, or skills, for AI coding tools including Codex, Claude Code, and Cursor. The skills cover work across 22 disciplines, including product strategy, accessibility, design, frontend and backend engineering, data, AI engineering, security, testing, delivery, marketing, and operations, and are supplied with working examples and an installer for adding them to a project. Its companion app lists the skills, supports search and filtering, shows which skills an agent loads, and lets users enable, disable, rewrite, or add skills from the web. The included Brief tool turns a code change into a visual report with source references for review before merging. The download also includes an optional image helper; the app requires Node 20 or newer, while the image helper requires Python 3.10 or newer and a compatible image-provider key. The product is sold as a one-time purchase with future Workshop editions included, and the skills can be used and edited in personal or client projects but not redistributed as a competing collection.

Agent Skills is an open-source collection of engineering workflows for AI coding agents, developed by Addy Osmani. It packages senior-engineering practices into skills covering the development lifecycle: defining specifications, planning, incremental implementation, testing and debugging, constraints, code review, web-performance auditing, code simplification, and shipping. Slash commands such as /spec, /plan, /build, /test, /review, and /ship activate the corresponding workflows, while skills can also activate automatically based on the work being performed. The /build workflow can generate a plan and implement its tasks in an approved pass, while retaining test-driven verification, individual commits, and pauses for failures or risky steps. It can be installed with the skills CLI or integrated into supported coding agents including Claude Code, Cursor, Codex, Copilot, and Cline.

self-learning-skills is a meta-skill for AI coding agents, including Claude Code, Cursor, Codex, and agents that read AGENTS.md or similar standing-instruction files. It recognizes hard-won, reusable procedures such as non-obvious commands and recurring operational workflows, then captures them as skills, rules, or project instructions for later sessions. The capture includes known dead ends and excludes one-off details and secret values. The project stores learned procedures as new skills/<name>/SKILL.md files for Claude Code, Codex, and Agent Skills clients; as .cursor/rules/learned/<name>.mdc files for Cursor; or in AGENTS.md or project notes for other agents. It can be installed with the community skills CLI, as a Claude Code plugin, or manually by copying the relevant files.

AI Design Skills is an MIT-licensed collection of Markdown design skills for AI coding tools such as Claude Code, Cursor, Codex, Windsurf, and Cline. Its skills provide coding agents with guidance for landing-page strategy, page structure, conversion copy, typography, spacing, visual systems, border radius, and motion. Each skill is stored as a self-contained folder with a SKILL.md file that can be copied into an agent's project-rules directory, added to a system prompt, or uploaded to a Claude.ai project. The repository currently documents a landing-page-design skill that asks intake questions, builds the page structure and copy, and defines the visual system; its design values are grouped in an editable section so users can change fonts, colors, spacing, and motion. The collection can be forked and used, modified, distributed, or used in commercial work under the MIT license.
