When is a GitHub Copilot Space the better choice than general or repo-wide chat?
When you need broad discovery across many repositories
When you want consistent, reproducible answers on a tightly scoped topic
When you want Copilot to automatically discover any relevant content in your org
When you have no specific task or domain in mind
Which statement about Space ownership and description is true?
A Space must be organization-owned; personal Spaces aren't supported
The description changes Copilot's answers in the Space
You can choose personal or organization ownership (where available), and the description is for human readers
Ownership can't be changed once set, and descriptions affect answer quality
Which action does NOT add usable context for Copilot in a Space?
Attaching files or folders from a GitHub repository
Pasting URLs of GitHub issues and pull requests
Uploading a local file (for example, a text document or spreadsheet)
@-mentioning a Copilot extension so it can run in Space chat
How do Spaces handle security and access to linked items?
A Space grants temporary read access to all linked private repositories
A Space mirrors GitHub permissions and surfaces only what a viewer can already see
A Space creates a copy of private content that anyone with the link can access
A Space requires repo admins to approved list each viewer manually
You need branch-specific guidance or a historical snapshot in a Space. What should you do?
Change the repository's default branch to lock Space answers to that branch
Rely on general chat to retrieve older versions automatically
Narrow references to relevant files and add a brief example, or attach a text file with the exact content
Paste the sensitive historical content into free-text notes for convenience
Which prompting pattern best supports runnable, verifiable outputs in a Space?
Ask for a summary without constraints to keep the model creative
Confirm intent, add concrete constraints (formats, ranges, file paths), and request executable outputs with references
Use many broad instructions to widen the context as much as possible
Avoid referencing attached sources to prevent overfitting
You notice size warnings and increasingly vague answers from your Space. What's the best next step?
Add more examples to increase context so the model has more to learn from
Reduce sources or split the Space into smaller, single-job Spaces
Start @-mentioning people to pull in their expertise
Turn off repository linking so the Space doesn't change
You must answer all questions before checking your work.
