agent-skill-case-studies
Take well-designed Claude Agent Skills apart as teaching material and distill reusable design patterns.
There's almost no systematic reference for how to design a good Agent Skill — everyone writes by feel. But great Skills are the best teaching material themselves: how the structure is laid out, how the prompts are organized, how the tools are defined — take it apart and it's all reusable decisions. agent-skill-case-studies takes those good Skills apart, one by one.
What it solves
Common confusions when writing a Skill: how to split the structure, how detailed the prompts should be, how granular the tools, when to break out a subagent. Without examples you're left to trial and error. This repo distills the answers into cases:
| Teardown dimension | What to look at |
|---|---|
| Structure | How the Skill organizes files and trigger conditions |
| Prompt strategy | How to write instructions that stay robust without being verbose |
| Tool design | Tool granularity, how inputs and outputs are defined |
Core mechanism
It picks well-designed Claude Agent Skills from Anthropic's official set and the community (chess / pptx / pdf / artifacts-builder, etc.), takes each apart along structure, prompt strategy, and tool design, then distills reusable design patterns across them. It's a teardown-style collection, true to the "take good things apart and study them" spirit.
How to use
git clone or just read it on GitHub. Pick a Skill that interests you from the case index, walk through the teardown, and carry its design decisions into your own Skill.
In one line
It doesn't teach you to invent from scratch — it teaches you to understand and take away designs others have already validated.
