### Proposed solution

➜ git:(main) copilot --allow-all-tools -p "who are you"
I am **GitHub Copilot CLI**, a terminal assistant built by GitHub. I help with software engineering tasks like:

- Exploring and analyzing codebases
- Making surgical code changes to files
- Running builds, tests, and debugging
- Working with Git repositories
- Executing shell commands and development workflows

I can help you understand the code, make changes, run tests, or perform other development tasks. What would you like me to help with?

### Example prompts or workflows

this would help continue the conversations if i have further non-interactive session while resuming the earlier context.

e.g.

➜ git:(main) copilot --allow-all-tools -p "what's my last question?" --resume 916524aa-24ae-406d-899a-698d2c19dd57
Your last question was "who are you" - which I just answered by explaining that I'm GitHub Copilot CLI, a terminal assistant for software engineering tasks.
