make-skill-templateCreates new Agent Skills for GitHub Copilot: scaffolds the skill folder under .github/skills, writes SKILL.md with proper frontmatter and adds optional scripts, references and assets.
A meta-skill for authoring other skills. The agent creates the skill directory, generates a SKILL.md with valid frontmatter, writes the body and adds optional scripts, references and assets folders only when they are needed. Its outline includes frontmatter field requirements, description best practices, how to organize the body and a full example of a skill structure.
You attach the file to Copilot Chat when creating or refining a skill under .github/skills/, and it also helps check discoverability before committing. A validation checklist and a troubleshooting section close it out, and it points to sibling skills for reviewing skills, the repository development workflow and PR readiness review. A quick-start route duplicates the template itself as a starting point.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit f3bf20f. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Links to these hosts (documentation or services it may open):
agentskills.ioplatform.claude.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Skill Scaffolding for GitHub Copilot loads about 2.5k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 1,007 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/make-skill-template/SKILL.md (or your agent's skills folder).A meta-skill for creating new Agent Skills. Use this skill when you need to scaffold a new skill folder, generate a SKILL.md file, or help users understand the Agent Skills specification.
Attach this file to your Copilot Chat context, then invoke it when creating or
refining a skill under .github/skills/. Use it to scaffold new skills and to
check discoverability quality before committing.
Create a new folder with a lowercase, hyphenated name:
.github/skills/<skill-name>/
└── SKILL.md # RequiredEvery skill requires YAML frontmatter with name and description:
---
name: <skill-name>
description: '<What it does>. Use when <specific triggers, scenarios, keywords users might say>.'
---| Field | Required | Constraints |
|---|---|---|
name | Yes | 1-64 chars, lowercase letters/numbers/hyphens only, must match folder name |
description | Yes | 10-1024 chars, must describe WHAT it does AND WHEN to use it |
license | No | License name or reference to bundled LICENSE.txt |
compatibility | No | 1-500 chars, environment requirements if needed |
metadata | No | Key-value pairs for additional properties |
allowed-tools | No | Space-delimited list of pre-approved tools (experimental) |
CRITICAL: The description is the PRIMARY mechanism for automatic skill discovery. Include:
Good example:
description: 'Toolkit for testing local web applications using Playwright. Use when asked to verify frontend functionality, debug UI behavior, capture browser screenshots, or view browser console logs. Supports Chrome, Firefox, and WebKit.'Poor example:
description: 'Web testing helpers'After the frontmatter, add markdown instructions. Recommended sections:
| Section | Purpose |
|---|---|
# Title | Brief overview |
## When to Use This Skill | Reinforces description triggers |
## Prerequisites | Required tools, dependencies |
## Step-by-Step Workflows | Numbered steps for tasks |
## Troubleshooting | Common issues and solutions |
## References | Links to bundled docs |
For standards and review skills, rules are mandatory unless explicitly marked
Optional. For advisory skills, distinguish requirements, recommendations, and
examples with consistent labels.
Define named thresholds, modes, phases, or terms before first use, and keep one authoritative definition for each concept.
State each policy definition (what the policy is, its exceptions, their criteria) once, in a single designated authority section, and link to that authority by anchor from every other skill or section that needs the policy. Keep role-specific operational instructions (what to do, flag, or test) inline in the document whose role they serve. Restated definitions silently rot when the authority changes, while a link cannot drift and an instruction stated in only one place cannot drift. A reader executing a workflow or checklist must never need the linked definition to perform an action — they follow the link only to understand why.
Use real markdown headings for durable rule sections. Avoid bold paragraphs as pseudo-headings when the section may need a table-of-contents entry, deep link, or review reference.
| Folder | Purpose | When to Use |
|---|---|---|
scripts/ | Executable code (Python, Bash, JS) | Automation that performs operations |
references/ | Documentation agent reads | API references, schemas, guides |
assets/ | Static files used AS-IS | Images, fonts, templates |
templates/ | Starter code agent modifies | Scaffolds to extend |
Target SKILL.md under 500 lines; review carefully above 600 lines. Exceeding
the target is acceptable when splitting always-needed workflow or review rules
would make the skill less effective. Split situational references first.
Keep these in SKILL.md:
Move these to reference files:
Each reference file should state its purpose and when the agent should load it.
Keep references one level deep from SKILL.md.
When one skill extends another, state what it inherits, overrides, or adds. Link to the parent skill or reference file and keep child-skill overrides narrow.

Creates new Agent Skills for GitHub Copilot: scaffolds the skill folder under .github/skills, writes SKILL.md with proper frontmatter and adds optional scripts, references and assets. A meta-skill for authoring other skills.md with valid frontmatter, writes the body and adds optional scripts, references and assets folders only when they are needed.
Skill Scaffolding for GitHub Copilot fits situations like: creating a new skill for a GitHub Copilot setup; scaffolding a skill folder with scripts, references or assets; improving a skill's description so it is easier to trigger; learning what the Agent Skills specification expects.
Run `npx skills add ruby-git/ruby-git --skill make-skill-template -a claude-code`. Or copy the skill folder (.github/skills/make-skill-template in ruby-git/ruby-git) into .claude/skills/make-skill-template in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ruby-git/ruby-git --skill make-skill-template -a codex`. Or copy the skill folder (.github/skills/make-skill-template in ruby-git/ruby-git) into .agents/skills/make-skill-template in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruby-git/ruby-git --skill make-skill-template -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/make-skill-template, .gemini/skills/make-skill-template, .github/skills/make-skill-template and .opencode/skills/make-skill-template in your project.
SKILL.md names no scripts, command-line tools or credentials: Skill Scaffolding for GitHub Copilot is instructions for the agent only. Our summary lists: GitHub Copilot Chat with the skill file attached.
SKILL.md names 2 domains. As links in the text: agentskills.io and platform.claude.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Skill Scaffolding for GitHub Copilot is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.5k tokens (SKILL.md is roughly 9.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
