Feedback from a test run on Rocky Linux (x86_64)

Environment: Rocky Linux / x86_64, non-sudo user

What worked ✅

• gh via webi — already installed, idempotent (v2.92.0)
• uv install — clean and fast (v0.11.15)
• Homebrew clone to ~/.linuxbrew — worked; subsequent runs correctly skip the clone
• VS Code portable tar.gz install — downloaded and extracted fine (~202MB)
• Python 3.12 via uv python install 3.12 — installed cpython-3.12.13 without issue

Notes ⚠️

• Step 6 (Copilot extension) is outdated for gh v2.92.0+: gh extension install github/gh-copilot fails with "copilot" matches the name of a built-in command or alias. As of gh v2.x, gh copilot is a built-in — no extension install needed.
• Copilot binary location changed: The built-in gh copilot downloads the binary to ~/.local/share/gh/copilot/copilot (not ~/.local/share/gh/extensions/gh-copilot/gh-copilot). The symlink path in step 6a should be updated to:

  COPILOT_BIN="$HOME/.local/share/gh/copilot/copilot"

Suggested fix for steps 5–6a

Replace the Copilot extension install + symlink block with:

# Trigger gh to download the built-in copilot binary
gh copilot --version

# Symlink to ~/.local/bin
COPILOT_BIN="$HOME/.local/share/gh/copilot/copilot"
COPILOT_LINK="$BIN_DIR/copilot"
if [ -f "$COPILOT_BIN" ]; then
    ln -sf "$COPILOT_BIN" "$COPILOT_LINK"
    echo "✅ copilot symlink created: $(ls -la "$COPILOT_LINK")"
else
    echo "⚠️  Copilot binary not found at $COPILOT_BIN"
