Tutorial update needed: new utility commands /ask, /env, and /statusline not covered

[github-actions]

Summary

Three new slash commands were added in v1.0.25–v1.0.30 and are documented in official sources and the github/copilot-cli-for-beginners course, but none appear in the tutorial.

What changed

• /ask (v1.0.27, 2026-04-15): Ask a quick question without affecting conversation history. Useful for one-off lookups mid-task without polluting your context.
• /env (v1.0.25, 2026-04-13): Show loaded environment details — which custom instructions, MCP servers, skills, agents, and plugins are currently active. Replaces the now-removed --list-env flag (removed in v1.0.30).
• /statusline (alias /footer) (v1.0.30, 2026-04-16): Customise the status bar items shown at the bottom of the CLI (directory, branch, effort, context window, quota).

The github/copilot-cli-for-beginners course added /ask, /env, and /statusline to its Chapter 01 command reference (commits Apr 15–17, 2026).

Note: --list-env was removed in v1.0.30 — if the tutorial mentions it anywhere, that reference must be updated to use /env.

What needs updating

• Lesson 14 (Session Management): Add /ask (ephemeral questions) and /env (environment inspection) to the concepts section and exercise hints
• Lesson 16 (Model Selection & Configuration) or Lesson 14: Add /statusline as a way to customise the CLI's status bar
• Any lesson mentioning --list-env should be updated to use /env instead
