Copilot Coding Agent (Cloud Agent)

The Copilot Coding Agent lets Copilot autonomously work on GitHub issues:

1. Go to a GitHub Issue in your browser
2. Click "Assign to Copilot" (or mention @github-copilot in a comment)
3. Copilot opens a PR with the solution
4. Review the PR, request changes if needed, and merge

Tips:

• Write clear, detailed issue descriptions — the agent works from the issue text.
• The agent works best on well-scoped, single-concern issues.
• Always review the agent's PR before merging.

Multi-Account Workflow

When working across both accounts (Mac + Windows):

1. Each account has its own Copilot Pro subscription — they work independently.
2. Both accounts can collaborate on the same Hoppe-home organisation repos.
3. Copilot suggestions are personal — they do not sync between accounts.
4. Use GitHub Issues and PRs to hand off work between accounts.

Best Practices

• ✅ Always review Copilot suggestions before accepting
• ✅ Use Copilot Chat to understand unfamiliar code
• ✅ Use the Coding Agent for well-defined GitHub issues
• ✅ Write good commit messages — Copilot can help with these too
• ❌ Don't accept suggestions blindly — Copilot can hallucinate
• ❌ Don't use Copilot to generate secrets, passwords, or credentials
