Verifying claude-for-msft-365-install

This plugin is admin CLI tooling, not an app. There is nothing to build and no server to boot. The surface is the terminal: scripts/*.sh on macOS, scripts/*.ps1 on Windows.

Lint gate

python3 scripts/check.py           # from the REPO ROOT, not the plugin dir
bash -n claude-for-msft-365-install/scripts/<script>.sh

check.py lints every manifest and self-installs the pre-commit hook that patch-bumps .claude-plugin/plugin.json. Run it before committing.

Drive the scripts against a fake $HOME

Every macOS script resolves Office paths from $HOME, so overriding it gives a throwaway sandbox — you can exercise the destructive --apply paths without touching real Office data.

S=<scratchpad>/sandbox
for app in Excel Word Powerpoint; do
  mkdir -p "$S/Library/Containers/com.microsoft.$app/Data/Documents/wef"
done
printf '<x/>' > "$S/Library/Containers/com.microsoft.Excel/Data/Documents/wef/aaaaaaaa-1111-1111-1111-111111111111.manifest-a.xml"

HOME=$S ./scripts/clear-addin-cache.sh                      # list
HOME=$S ./scripts/clear-addin-cache.sh --id <GUID>          # dry-run
HOME=$S ./scripts/clear-addin-cache.sh --id <GUID> --apply  # destructive

Seed at least two IDs across two apps, with mixed upper/lowercase. Both properties have caught real bugs: cross-app blast radius, and a case-sensitive glob that reported "already clear" and sent admins to a folder-wide wipe.

Prove storage is retained

The load-bearing claim of this plugin is that clearing a manifest never touches the user's chat history. Verify it by snapshot-diffing both trees around the operation, against the real $HOME:

snap() {
  for app in Excel Word Powerpoint; do
    find "$HOME/Library/Containers/com.microsoft.$app/Data/Library/WebKit/WebsiteData" \
         -type f -exec stat -f '%N %z %m' {} \; 2>/dev/null
    find "$HOME/Library/Containers/com.microsoft.$app/Data/Documents/wef" \
         -type f -exec stat -f 'WEF %N %z' {} \; 2>/dev/null
  done | sort
}
snap > before.txt;  <run the script>;  snap > after.txt;  diff before.txt after.txt
