🛠️ Show & Tell: What Custom Copilot Skills Have You Built? Share Your SKILL.md Files!

[shinybrightstar]

👋 Hey Community!

Custom Skills (SKILL.md) are one of the most powerful, and most under-documented, features in GitHub Copilot. We've seen incredible things being built in this community, from deterministic React UI generators to multi-agent orchestration workflows for full-stack development.

But right now, there's no central place to discover what others have built, learn from their SKILL.md file structures, or get inspired for your next custom skill.

Let's change that. 🚀

Share your custom Copilot Skill!

Reply to this thread with:

1. 🏷️ Skill name -- What does your skill do?
2. 🎯 Problem it solves -- What was flaky, slow, or impossible before this skill?
3. 📄 Your SKILL.md (or a snippet) -- Show us the actual file! Frontmatter, instructions, example references — the more detail, the better.
4. 🖥️ Where it works -- VS Code? CLI? github.com? PR review? All of the above?
5. 💡 One thing you learned -- What surprised you, tripped you up, or took the longest to figure out?

Not sure where to start?

Here are some skill ideas based on what the community has been asking about:

Idea	Who's asking	Source
Code style enforcer — Make Copilot follow your team's exact coding conventions	Teams frustrated with inconsistent AI output	Multiple CLI & Skills threads
Database schema generator — Generate migration files from natural language	Full-stack developers building multi-skill workflows	#192232
PR review checklist — A domain-specific validation skill for code review	Teams using Copilot Code Review	#191616
Test scaffolder — Generate test boilerplate matching your team's patterns	Developers who want consistent test structure	Community pattern
API contract validator — Ensure generated code matches an OpenAPI spec	Backend teams with strict API contracts	Community pattern
Deterministic UI layout — Force consistent React/Vue component structure	Frontend developers (already built! See #189283)	#189283

Quick reference: SKILL.md file structure

For anyone new to custom skills, here's the basic anatomy:

.github/skills/my-skill/
├── SKILL.md          ← The main skill definition
└── examples/         ← Optional: example code for the skill to reference
    ├── good.py
    └── bad.py

Your SKILL.md file typically contains:

• YAML frontmatter — metadata like name, description, and scoping
• Instructions — what the skill should do, in natural language
• Context sections — example patterns, constraints, and references
