Agent Skills

A curated collection of 44+ AI agent skills — structured knowledge files that teach coding agents (Windsurf/Cascade, Claude Code, Cursor, Codex, Gemini CLI) how to accomplish complex tasks. Spanning visual asset creation, platform operations, AI-agent auditing, writing, marketing, and content strategy.

What Are Agent Skills?

Agent skills are structured SKILL.md files that give AI coding agents deep expertise in specific tools and workflows. Instead of relying on generic training data, skills provide:

• Step-by-step instructions tailored for AI agents
• Code templates and scaffolding commands
• Decision trees for choosing the right approach
• Common pitfalls and how to avoid them
• Combination patterns for multi-tool workflows

How to Use

For Windsurf / Cascade

Reference skills in .windsurf/rules/ or instruct the agent directly:

Read the Remotion skill from skills/remotion/SKILL.md and create a product intro video

For Claude Code

cat skills/remotion/SKILL.md  # Load into context

For Cursor

Reference in .cursorrules or load directly.

For Any Agent

Point to the AGENTS.md manifest for automatic skill discovery:

Read AGENTS.md and help me create a [product video / animated presentation / data visualization]
