At a glance
Guides creating, updating, reviewing and validating GitHub Copilot agent skills, from deciding whether a skill is the right tool to structuring bundled resources.
- Works in 5 steps: Discovery → Architecture → Craft → …
- Creating a new Copilot skill from scratch
- SKILL.md covers What Is a Skill, Skill Anatomy, When to Use and Is a Skill the Right Vehicle?, plus 8 more sections
- Runs Python scripts from its folder; calls python
What it does
This skill helps write SKILL.md files for GitHub Copilot, stored under .github/skills. It explains what a skill is and its three loading levels: metadata that is always in context and acts as the trigger, the SKILL.md body loaded when it triggers and kept under 500 lines, and bundled scripts, references and assets loaded on demand. It also says what to leave out, such as setup guides, changelogs and user-facing documentation.
Before creating anything it asks whether a skill is the right vehicle, comparing it with copilot-instructions entries, file-scoped instruction files, one-off prompt files and dedicated agent files. For a skill, it covers writing the description for reliable triggering, folder structure and bundled resources. Helper scripts initialize a skill and run a quick validation, and references hold output patterns, a quality checklist and workflow patterns.
It is not meant for general coding questions, runtime debugging or MCP server configuration; those fall outside skill authoring and should be handled in the normal way.
When your agent uses it
- Creating a new Copilot skill from scratch
- Turning a repeated workflow into a reusable skill
- Improving an existing SKILL.md description so it triggers reliably
- Deciding between a skill, an instructions file and a prompt file
Example prompts
- “Create a Copilot skill for reviewing our Bicep modules.”
- “Turn the steps we just used to rotate secrets into a reusable skill.”
- “Validate my SKILL.md and tell me what to improve.”
Requirements
- Python 3 for the init and validation scripts
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Discovery
- Architecture
- Craft
- Validate
- Deliver
What it can do on your machine
Read from SKILL.md and the folder at commit 554ac0b. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Copilot Skill Creator loads about 4.1k tokens when it runs, and up to ~7.8k if it reads all its reference files. Until then it costs about 148 tokens; SKILL.md has 1,911 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.
Safety
Auto-check passed
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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,911 words (~4,111 tokens).
“Create high-quality GitHub Copilot agent skills (SKILL.md) that transform the general-purpose agent into a specialized expert.”
