spaget vs writing copilot instructions by hand
Compare hand-writing GitHub Copilot instruction files vs generating them with spaget's visual builder.
How Copilot instructions work
GitHub Copilot uses .github/copilot-instructions.md to customize how it assists you in a repository. This file contains natural language instructions that tell Copilot about your project’s conventions, preferred patterns, and things to avoid.
It’s straightforward: write markdown, save it, and Copilot uses it as context when generating suggestions.
The limitations of manual instructions
Simple format, complex decisions
The file format is easy — it’s just markdown. But deciding what to write is the hard part. What instructions actually improve Copilot’s output? How specific should you be? How do you structure instructions so Copilot weighs them correctly?
Limited ecosystem
Compared to Claude Code and Cursor, GitHub Copilot’s instruction system is simpler. There’s no equivalent of Cursor’s per-file glob rules or Claude Code’s structured sections. This simplicity makes it easy to start but harder to build sophisticated configurations.
No templates or community resources
There’s no official gallery of Copilot instruction templates. You’re writing instructions based on GitHub’s documentation and your own experimentation.
Platform lock-in
Instructions written for Copilot only work with Copilot. If you also use Claude Code or Cursor — which is increasingly common as developers use different AI tools for different tasks — you’re maintaining separate instruction sets.
spaget vs manual Copilot instructions
| Copilot Instructions (Manual) | spaget | |
|---|---|---|
| Format | Simple markdown | Visual builder |
| Starting point | Blank file | Templates + skills |
| Validation | None | Built-in |
| Export targets | Copilot only | Copilot + Claude Code + Cursor |
| Community content | Limited | Skill library |
| Maintenance | Edit markdown | Update once, re-export |
| Cost | Free | Free |
Visual building for simple configs
Even though Copilot’s instruction format is simple, the visual builder makes configuration faster. Pick your tech stack, add relevant skills, and export. spaget generates clean, well-structured instructions optimized for Copilot’s parsing.
Cross-platform consistency
The real value for Copilot users is cross-platform support. Many developers use GitHub Copilot alongside Claude Code or Cursor. With spaget, one configuration serves all three:
- GitHub Copilot —
.github/copilot-instructions.md - Claude Code —
CLAUDE.md - Cursor —
.cursor/rules/*.mdc
Same rules, same conventions, every tool.
Community skills for Copilot
Browse skills created by other developers and add them to your Copilot configuration. React patterns, testing conventions, API design guidelines — skills that would take research and iteration to write from scratch.
When manual instructions make sense
Stick with manual instructions when:
- You only use GitHub Copilot and your instructions are short and simple.
- Your instructions are minimal — a few lines of project context.
- You want to keep things lightweight without adding another tool to your workflow.
When spaget adds value
Use spaget when:
- You use Copilot alongside other AI tools — one config, every platform.
- You want a stronger starting point than a blank file — templates and community skills.
- Your team needs shared instructions — everyone exports from the same source.
- You want to build a comprehensive configuration with skills, conventions, and patterns that go beyond basic instructions.
