# Wondel.ai Skills

> 50 frameworks from bestselling business and engineering books — StoryBrand, Jobs to Be Done, $100M Offers, Clean Code and 46 more — packaged as free, MIT-licensed AI agent skills, plus 12 guided journeys that run them end to end.

An agent skill is a folder of instructions your AI coding agent loads on demand. These follow the open https://agentskills.io standard, so they work in Claude, Claude Code, Claude Cowork, Codex, Cursor, OpenClaw, Hermes Agent and any other compatible agent.

## Learn
Plain explanations of what agent skills are, how they differ from MCP and subagents, and how to install them. Also available as HTML at https://skills.wondel.ai/learn/<slug>/.

- [What Is an AI Agent Skill?](https://skills.wondel.ai/learn/what-is-an-ai-agent-skill.md): A skill is a folder of instructions your AI agent loads on demand — a SKILL.md plus any scripts it needs. What goes in the folder, how the agent decides to load it, and why that beats pasting the same prompt every session.
- [Claude Skills vs MCP: Which One Do You Actually Need?](https://skills.wondel.ai/learn/claude-skills-vs-mcp.md): A skill teaches an agent how to do something; MCP gives it a live connection to a system. Where each one wins, when MCP is genuinely the right answer, what they cost in context, and how to compose them.
- [Skills vs Subagents vs Slash Commands vs CLAUDE.md: What Goes Where](https://skills.wondel.ai/learn/skills-vs-subagents-vs-prompts.md): Four ways to give a coding agent instructions, and one question that decides between them: what can you afford to have in context on every single turn? A practical map, with the context-window arithmetic.
- [How to Install Claude Code Skills](https://skills.wondel.ai/learn/how-to-install-claude-code-skills.md): The practical install walkthrough: the one-line npx command, what --global really changes, where skills live in Claude, Claude Code, Claude Cowork, Codex, Cursor, OpenClaw and Hermes Agent, how to install by hand, and why a skill sometimes never triggers.
- [SKILL.md, Explained](https://skills.wondel.ai/learn/skill-md-explained.md): The anatomy of the one required file in an agent skill: every frontmatter field, why description decides whether your skill ever loads, how long the body should be — annotated with a real, shipping SKILL.md.
- [The Agent Skills Standard: One Format, Many Agents](https://skills.wondel.ai/learn/agent-skills-standard.md): What agentskills.io is, what a shared skill format solves that per-vendor prompt files never could, what the specification actually defines, and how to tell whether an agent supports it — including what's still unsettled.
- [How to Write an Agent Skill](https://skills.wondel.ai/learn/how-to-write-an-agent-skill.md): A practical guide to authoring a skill that actually fires: choosing a triggerable scope, writing the description as a trigger rather than a summary, keeping the body short with the depth in reference files, and testing whether it changed the output.
- [Claude Code Skills Libraries: An Honest Roundup](https://skills.wondel.ai/learn/claude-code-skills-libraries.md): A fair comparison of the main open skills libraries for Claude Code and other agents — Superpowers, Corey Haines' marketing skills, Anthropic's official repo, book-derived collections, and ours — with straight guidance on which to install for which job.
- [Clean Code vs Clean Architecture: Same Author, Different Altitude](https://skills.wondel.ai/learn/clean-code-vs-clean-architecture.md): Clean Code governs what happens inside a function; Clean Architecture governs which way dependencies point between modules. What each one actually rules on, why neither rescues the other, and which to reach for given a specific symptom.
- [Domain-Driven Design vs Clean Architecture: What Is the Boundary Drawn Around?](https://skills.wondel.ai/learn/domain-driven-design-vs-clean-architecture.md): DDD draws boundaries around meaning — bounded contexts, ubiquitous language, aggregates. Clean Architecture draws them around dependency direction. How they compose, what each one does that the other cannot, and when DDD is genuinely overkill.
- [Lean Startup vs Design Sprint: Which One Should You Run?](https://skills.wondel.ai/learn/lean-startup-vs-design-sprint.md): One is a loop with no end date; the other is five days with a fixed agenda. What each actually produces, when a sprint is the cheaper way to buy the answer, when it is theatre, and how the two compose.
- [Positioning vs Messaging: Which One Is Actually Broken?](https://skills.wondel.ai/learn/positioning-vs-messaging.md): Positioning is the context you choose; messaging is the words that follow from it. Why homepage rewrites so often change nothing, a symptom test that tells you which one is broken, and the order Obviously Awesome and StoryBrand run in.
