How to use the Copilot Instructions Blueprint Generator agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The Copilot Instructions Blueprint Generator is an agent skill that tells an AI agent to read an existing codebase and write a copilot-instructions.md file. That file guides GitHub Copilot to produce code that follows your project's standards, architecture and exact library versions. This guide explains what the skill does, how to install it, how to trigger it, and how to review the output before you commit it.

- 1Download the ZIP. Download the skill's ZIP from the skill page on this site.
- 2Unzip the skill. Unzip it into ~/.claude/skills/ for personal use, or into the project's .claude/skills/ folder for one project.
- 3Or upload in the Claude apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the skill.
- 4Open your project. Make sure the agent has access to the repository you want to describe.
- 5Ask in plain language. Request a copilot-instructions.md file based on existing code patterns, naming any options you care about.
- 6Review the draft. Check versions, naming and testing rules against your code and edit anything that is generic or wrong.
- 7Commit the file. Once reviewed, save the file where Copilot reads it, such as .github/copilot-instructions.md, and commit it.
What is an agent skill and what does this one do?
An agent skill is a folder containing a SKILL.md file that gives an AI agent instructions for a specific task. This skill is for one task: producing a copilot-instructions.md file for a project.
The skill guides the agent to detect language and framework versions from project files such as package.json, .csproj, pom.xml and requirements.txt, and to look for patterns in existing code rather than inventing conventions. You choose options such as architecture style, code quality focus, documentation level, testing approach and versioning approach, and the generated instructions reflect those choices.
- Detects language, framework and library versions from project files
- Scans existing files for naming, error handling, logging, documentation and testing patterns
- Checks .github/copilot context files (architecture.md, tech-stack.md, coding-standards.md, folder-structure.md, exemplars.md) if they exist
- Offers configuration choices: project type, architecture style, quality focus, documentation level, testing requirements and versioning
How do you install the skill?
You can install the skill in either of two ways. Download the ZIP from the skill's page on this site and unzip it into your personal skills folder, ~/.claude/skills/, or into a project's .claude/skills/ folder so that it applies only to that project.
Alternatively, in the Claude apps, go to Settings, then Capabilities, then Skills, and upload the skill there.
- Personal install: unzip into ~/.claude/skills/
- Project install: unzip into the project's .claude/skills/ folder
- Claude apps: Settings → Capabilities → Skills, then upload
How do you trigger the skill with a natural request?
Once installed, you do not need to type a special command. Describe what you want in plain language while the agent has access to your project. The agent should recognise the request and follow SKILL.md.
Good requests name the output file and the purpose, for example asking the agent to create a copilot-instructions.md file for this repository so that Copilot matches our existing patterns. Mention the options that matter to you, such as a testing approach or documentation level, so the generated rules reflect them.
- "Create a copilot-instructions.md for this repo based on the existing code patterns."
- "Generate Copilot instructions for this project with a Comprehensive documentation level and a Testability focus."
- "Draft .github/copilot-instructions.md from our current architecture and test style, and don't assume any conventions we don't already use."
What do you need before you start?
The skill needs an AI agent that can read your project's files and follow SKILL.md, such as Claude Code or another compatible SKILL.md runtime. It also helps to use GitHub Copilot in a setup that reads .github/copilot-instructions.md files, since that is where the output is meant to be used.
The skill works best on a mature codebase with established patterns. It is not a good fit for a project with little or no existing code, because the generator relies on patterns it can find in the codebase.
- An agent that can read project files and follow SKILL.md
- A GitHub Copilot setup that reads .github/copilot-instructions.md
- An existing codebase with patterns to learn from
What are the safety notes?
According to the skill's listing, it runs no scripts and uses no network access. It consists of a single SKILL.md file. Its effect is that the agent reads your project files and writes a document.
Because the output is only as accurate as the agent's reading of your code, review the generated copilot-instructions.md before committing it. Check every version number, naming rule and testing rule against your repository.
- Runs scripts: no
- Uses network: no
- Files: SKILL.md only
- Review generated rules before committing them
What tips improve the result?
Clean up the codebase signals first. The generator follows the patterns it finds, so inconsistent code produces inconsistent rules. Where patterns conflict, the skill directs the agent to prefer patterns in newer files or files with higher test coverage, so check that this matches what you want.
Treat the output as a draft. Edit it, remove rules that do not reflect your team's real practice, and keep it short enough that Copilot can use it.
- Keep .github/copilot context files up to date, since the skill reads them first
- Pick configuration options that match your real practice
- Review the draft against your code and edit before committing
What people use it for
- Onboarding GitHub Copilot onto a mature codebase so suggestions follow existing naming and error handling patterns.
- Drafting custom Copilot instructions that pin the library versions your project actually uses.
- Producing a starting document for a team to review and refine, rather than writing the file from scratch.
- Aligning Copilot with a chosen testing approach, such as matching the structure of existing unit tests.
Frequently asked questions
Is the copilot instructions blueprint generator free?
The skill is published under the MIT licence, which governs use of the source. Any costs depend on the AI agent or Claude plan you use to run it, which this skill does not set.
What do I need to run this skill?
You need an AI agent that can read your project files and follow SKILL.md, such as Claude Code or a compatible runtime. You also benefit from a GitHub Copilot setup that reads .github/copilot-instructions.md.
How do I install the copilot-instructions-blueprint-generator skill?
Download the ZIP from this page and unzip it into ~/.claude/skills/ or a project's .claude/skills/ folder. In the Claude apps you can instead upload it under Settings → Capabilities → Skills.
Does the skill run scripts or access the internet?
According to the listing, it runs no scripts and uses no network access. It contains only a SKILL.md file.
Will the generated instructions be correct automatically?
Not guaranteed. The file is only as accurate as the agent's reading of your code, so review version numbers and rules before committing.
Does this work on a new project with little code?
It is not recommended. The generator relies on patterns it can find in existing code, so a project with little or no code may get generic or wrong rules.

Our verdict
Use this skill if you maintain a mature codebase and want a reviewable first draft of copilot-instructions.md that reflects your existing versions and patterns. Skip it for new or nearly empty projects, or if you expect the output to be correct without reading it, and write the file by hand or pick a generator that suits your workflow.
