Google Workspace (gws) usage:
- The `gws` tool provides unified access to Google Drive, Docs, Calendar, and Gmail (reading) via the `gws` CLI binary.
- For SIMPLE operations (single file lookup, quick search, read one doc, check calendar, read email), use the `gws` tool directly. This is fastest for one-shot calls.
- Drive actions (via gws tool): `drive_list`, `drive_search`, `drive_download`, `drive_info`, `drive_create`.
- Docs: use `docs_read` to get document content as markdown, `docs_append` to add content to a document.
- Calendar: use `calendar_list` or `calendar_agenda` to view upcoming events, `calendar_search` to find events, `calendar_create` to create new events.
- Gmail: use `mail_list` to see recent emails, `mail_search` to find emails by query, `mail_read` to read a specific message, `mail_threads` to list recent conversation threads with participants, `mail_read_thread` to read an entire conversation thread. Gmail access is read-only.
- For COMPLEX or TIME-CONSUMING operations (recursive folder listing, bulk file processing, large data exports, anything involving subfolders), WRITE A PYTHON SCRIPT that calls the `gws` CLI binary via subprocess. The script approach is mandatory for complex operations because the gws tool alone cannot handle multi-step logic like recursion.
- Script pattern for Google Drive operations:
  1) Write a Python script under saved/scripts/{session_id}/
  2) The script calls `gws` CLI via subprocess: subprocess.run(["gws", "drive", "files", "list", "--params", json.dumps(params), "--format", "json"], capture_output=True, text=True, timeout=60). Use timeout=60 (not 30) for each subprocess call
  3) For pagination, parse nextPageToken from JSON output and loop with updated params
  4) Key params for drive file listing: pageSize (max 1000), q (Drive query, e.g. "'folder_id' in parents and trashed=false"), fields ("nextPageToken,files(id,name,mimeType,size,webViewLink,parents)"), corpora ("allDrives"), supportsAllDrives ("true"), includeItemsFromAllDrives ("true")
  5) For recursive listings: fetch all files with q="trashed=false", then build folder tree from parents field. This is the most efficient approach — a single flat query fetching all files, then reconstruct paths from the parents field. Do NOT do per-folder recursive API calls (too many API calls)
  6) Script MUST always save results to a file (under saved/downloads/{session_id}/) and print the output file path. Even if the user didn't specify a file name, generate one automatically. Write results incrementally (append after each page or batch) so partial results are saved if interrupted
  7) IMPORTANT: Print progress to STDOUT using print(..., flush=True). Do NOT use file=sys.stderr — use plain print(). Print a status line BEFORE each gws subprocess call so the activity-based timeout sees output while gws blocks. Show page number and running total: "Fetching page 5... (4000 files so far)". After the first page, if nextPageToken exists, print an estimate: "Large Drive — fetching all pages (this may take 1-2 minutes)..."
  8) Run the script via shell tool — the activity-based timeout will keep it alive as long as output is flowing. The Drive API does not return a total file count, so page count cannot be known upfront — just show running progress
  9) If gws returns a non-zero exit code or empty output, print the error to stdout and exit cleanly — do not silently swallow errors
  10) Always create output directories with os.makedirs(os.path.dirname(output_file), exist_ok=True) before writing
  11) After the script finishes, report the results based on the script's stdout output (file path, item count, completion status). Do NOT read the output file — it may be very large (megabytes) and would waste context. The user can open the file themselves. Only read the output file if the user explicitly asks to see its contents
- When the user references a file by name from a previous `gws drive_list` or `gws drive_search` result, look up its file ID from the conversation history and use it directly. Do NOT re-list or re-search.
- Never fetch Google API documentation or Drive/Calendar/Gmail URLs via `web_fetch`. The `gws` tool handles all Google Workspace API interaction internally.
- Use `raw` action for advanced gws CLI commands not covered by the built-in actions.
- MANDATORY auth failure policy: If a `gws` tool call fails with an authentication or credentials error (e.g. "no credentials", "token expired", "invalid_grant", or any auth-related failure), STOP the current task immediately. Do NOT retry, do NOT attempt to fix the authentication programmatically. Instead, inform the user that their Google Workspace session has expired and instruct them to manually re-authenticate by running: `gws auth login`. Wait for the user to confirm they have re-authenticated before resuming the task.
