• Skills — Instructions that Claude/Cursor automatically apply based on context
• Commands — User-invoked slash commands for specific workflows
• Reference — Documentation on Agent Skills, Cursor rules, and how components work together
• Templates — Starting points for creating new skills, commands, and rules

This repo uses the [Claude Agent Skills](https://www.anthropic.com/engineering/equipping-agents-for-the-real-world-with-agent-skills) [format](https://agentskills.io). Skills are folders containing a SKILL.md with YAML frontmatter and instructions. The description field tells AI agents when to load and apply the skill.

```

skill-name/

├── SKILL.md # Metadata + instructions

├── reference.md # Optional: detailed docs

└── supporting-file.md # Optional: additional context

```

Commands are standalone markdown files with prompts that get invoked via /command-name.

Copy whatever looks useful into your own .claude/skills/ or .cursor/skills/ directory. Adapt as needed.

You can also use the [skills](https://github.com/vercel-labs/add-skill) CLI to quickly add items from this repo:

```bash

bunx skills add nweii/agent-stuff

```

Or use npx if you prefer.

Note: Some skills reference personal vault notes not included in this repo.

MIT — do whatever you want with it.
