description	Enable the Copilot CLI Cost /cost command and panel by installing the user-scoped SDK extension shim that imports the installed plugin.

Use this skill when the user asks to install, enable, set up, or repair the Copilot CLI Cost /cost command or cost panel after installing the plugin.

Goal:

• Locate the installed copilot-cli-cost plugin under the user's Copilot installed plugins directory.
• Run the plugin's deterministic shim installer script. The shim imports the installed plugin copy; Copilot CLI handles repo-local extension precedence when running inside a checkout.
• Tell the user to enable or reload the copilot-cli-cost user extension in /extensions if it is not already running.

Use the command for the user's shell.

PowerShell:

$installer = Get-ChildItem "$env:USERPROFILE\.copilot\installed-plugins" -Directory -Recurse |
  Where-Object { Test-Path (Join-Path $_.FullName "scripts\install-extension-shim.mjs") } |
  Select-Object -First 1 -ExpandProperty FullName

if (-not $installer) {
  throw "Could not find the installed copilot-cli-cost plugin. Run install.ps1 or install.sh first."
}

node (Join-Path $installer "scripts\install-extension-shim.mjs")

Bash/zsh:

installer="$(find "$HOME/.copilot/installed-plugins" -type f -path '*/scripts/install-extension-shim.mjs' | head -n 1)"
if [ -z "$installer" ]; then
  echo "Could not find the installed copilot-cli-cost plugin. Run install.ps1 or install.sh first." >&2
  exit 1
fi
node "$installer"

After the script succeeds, instruct the user:

1. Run /extensions.
2. Enable copilot-cli-cost under User, or toggle it off and on if it was already enabled.
3. Run /cost help to confirm the command is available.

Do not overwrite unrelated user extensions. If the installer reports that it refused to overwrite an existing non-Copilot-Cost extension, stop and explain that the user already has a user extension named copilot-cli-cost.
