/rename should auto-generate a session name based on conversation context #2292
Description
Describe the feature or problem you'd like to solve
/rename requires the user to manually type a session name.
Proposed solution
When running /rename without providing a name, the CLI should use the AI to automatically generate a concise, descriptive
session name based on the conversation history... similar to how Claude handles /rename.
Example prompts or workflows
- User has a long debugging session and wants to save it for later:
- Types /rename with no arguments
- Copilot analyzes the conversation and renames to: "debug-null-pointer-exception"
Additional context
After a long session, users shouldn't have to summarize the conversation themselves. Auto-naming improves session organization and
discoverability without friction.
