Ever felt frustrated when AI suggests code that ignores your team’s unique setup? 😔

AI feels magical… until it starts giving the wrong answers.

GitHub Copilot Spaces fixes that by letting you bundle the exact context Copilot should know: turning generic responses into answers that feel like they came from your team's resident expert.

GitHub Copilot Spaces: Your team's knowledge, on demand 💪🏽

Think of spaces as secure, shareable containers that hold your code files, docs, team conventions, and behavioral instructions. Once created, every Copilot interaction using that space is grounded in that curated knowledge.

• The problem it solves: No more wrong guesses from AI that doesn't know your monorepo mixes React with jQuery, or your security guidelines differ from the standard.
• Main benefit: Get commit-ready code and answers that match your team's patterns on the first try.
• Key feature: Bundle code, threads, wikis, and issues with custom instructions to teach Copilot your team’s style. Add issue or PR links to pull in titles, comments, and labels. Copilot responds with tailored help for tasks like planning or bug fixes.

Quick setup (5 minutes) ⚡

1. Go to github.com/copilot/spaces → Create space
2. Give it a clear name (e.g., "frontend-styleguide")
3. Attach context by pulling in code folders, pasting Slack threads, or dropping docs into the Text tab
4. Add custom instructions such as "Respond as a senior React reviewer. Enforce our ESLint rules."
5. Save, test the space with a question, and watch Copilot cite your attached files.

Real-world example 🌎

GitHub's accessibility team created a space with WCAG docs and their "Definition of Done" checklist. Now, instead of pinging the accessibility lead on Slack, developers ask questions like, "What steps are needed for compliance on this modal?" Copilot responds with specific checkpoints, doc references, and even suggests ARIA attributes or color fixes. The team pinned it in Slack for instant self-service guidance.

With Copilot Spaces, you’re not only going to get better AI responses, you’re making your team's collective expertise searchable and shareable. When organizational knowledge leaves people's heads and starts living in reusable spaces, everyone moves faster.
