Use already-installed `gws` or `gog` (gogcli) credentials when Hermes's own Google OAuth setup has not been run. Reuses the refresh token from the working CLI to call Gmail/Calendar/Drive APIs directly via curl, avoiding a full OAuth re-setup. Activates when `$GSETUP --check` returns NOT_AUTHENTICATED but `gws` or `gog` is on PATH and authenticated. Also handles user-shared Google Doc URLs (docs.google.com/document/d/<ID>/edit) — `gws` 403s on personal shared Docs (service-account auth), use `gog docs info` + `gog docs export --format txt` instead.

Use already-installed `gws` or `gog` (gogcli) credentials when Hermes's own Google OAuth setup has not been run. Reuses the refresh token from the working CLI to call Gmail/Calendar/Drive APIs directly via curl, avoiding a full OAuth re-setup. Activates when `$GSETUP --check` returns NOT_AUTHENTICATED but `gws` or `gog` is on PATH and authenticated. Also handles user-shared Google Doc URLs (docs.google.com/document/d/<ID>/edit) — `gws` 403s on personal shared Docs (service-account auth), use `gog docs info` + `gog docs export --format txt` instead.
Reuse an already-authenticated gws or gog (gogcli) install on the same machine instead of running the full Hermes Google Workspace OAuth setup. Useful when:
$GSETUP --check returns NOT_AUTHENTICATED.
The user already has gws or gog installed and authorized (likely from prior work).
You only need to read Gmail, list calendar events, or fetch a Drive/Docs file from a cron job or short-lived agent session.
References
references/daily-digest-cron-recipe.md — verified working recipe for a Gmail + Calendar → Slack morning digest cron (gog v0.10.0, --from/--to workaround for the --days bug).
When this skill applies, the bundled productivity/google-workspace skill's $GAPI wrapper cannot be used because no ~/.hermes/google_token.json exists. This skill provides the working alternative.
Verified 2026-07-09 against a host with both CLIs:
gws is authorized as firebase-adminsdk-…@worldarchitecture-ai.iam.gserviceaccount.com (service account, empty calendar).
gog is authorized as $USER@gmail.com (personal OAuth).
When to activate
Trigger condition: any task needs Gmail / Calendar / Drive / Docs / Sheets and $GSETUP --check says NOT_AUTHENTICATED. Before running the 5-step OAuth setup, check if a working CLI is already on the host:
which gws gog 2>&1
gog auth list 2>&1 # shows accounts + auth type (oauth / service-account)
If gog auth list shows the user account you need, skip Hermes OAuth setup and read the existing credentials file directly.
gog's credentials.json contains client_id, client_secret, and a refresh_token directly in the JSON — no keychain unlock required. Treat as a secret; never paste in chat/logs.
The services array and scopes array tell you which APIs the refresh token can hit (commonly: gmail, calendar, drive, docs).
2. Try the native CLIs first (fastest)
gog (gogcli) — preferred for personal Gmail/Calendar
GOG="-a $USER@gmail.com --enable-commands=gmail calendar"$gog$GOG gmail search "is:unread newer_than:3d" --max 15
$gog$GOG calendar calendars # list calendar IDs and roles
gws (googleworkspace/cli) — preferred for Workspace / service-account
calendarId in the URL must be URL-encoded (@ → %40). Use gog calendar calendars to enumerate the IDs the user can see; the OAuth default may be a service-account calendar that is empty by design — that's not a bug, just not the one you want.
Drive / Docs / Sheets / People
Same Bearer token + the appropriate https://www.googleapis.com/{drive|docs|sheets|people}/v3/... endpoints, provided the refresh token's services list includes them (it usually does for drive, docs).
4. When to write back to Hermes-managed credentials
Use the curl/gog path as a stopgap. If the user wants long-term canonical access from Hermes, run the bundled google-workspace skill's first-time setup once (Steps 2–5 in that skill's SKILL.md). You can speed it up by reusing the client_id/client_secret/refresh_token triple already in ~/Library/Application Support/gogcli/credentials.json — write it as a Desktop OAuth JSON, then $GSETUP --client-secret … against it. Step 4 (auth-code exchange) may not even be needed if the refresh token was minted against the same client_id.
After this, $GAPI gmail search … and $GAPI calendar list … work normally and should be used in place of the curl fallback.
5. Drive corpus search (find + read a constellation of Google Docs)
When the user asks "find all my old X campaigns / Y documents / Z shared notes" and the answer lives as a constellation of Google Docs (not a single one), use the Drive search pattern. Verified 2026-07-20 against $USER@gmail.com while finding the god-of-tyranny Aizen campaign corpus (16+ Google Docs spanning 2025-06-14 → 2026-02-09).
Drive search — the right gog subcommand is drive search, NOT docs search
Drive download — Google Docs export as PDF is automatic
# Google Doc → auto-exports as PDF (preserves structure, fonts, images)
gog drive download --file-id 1L1sOStC7rVjCzE8KHhpMf55TarmvNXNuEx-RH2vwO-0 \
--output ~/tmp/aizen_origin.pdf -a $USER@gmail.com
# Plain text file (.txt) → downloads as .txt directly
gog drive download --file-id 1HnRXmsl8rcB5_ZNmO7WkDIxhTTZCZw0n \
--output ~/tmp/aizen_godhood_3.txt -a $USER@gmail.com
# PDF (e.g. "Aizen god campaign book 2.pdf") → downloads as PDF
gog drive download --file-id 1hkW_iJZCy7CoOZfCuuj__Q_qz6IGPEE7 \
--output ~/tmp/aizen_book2.pdf -a $USER@gmail.com
Then pdftotext <pdf> - to extract text. Some PDFs (especially older Google Docs) fail pdftotext cleanly — fall back to pdfinfo for metadata + the Drive webViewLink for manual read.

Why this exists
gws403s on personal shared Google Docs (it's authorized to a service account). gog drive search + gog drive download is the working path for the user's own account, and it preserves the Google-Doc-as-PDF auto-export behavior. Verifying a Google Doc was correctly retrieved means: download size > 50 KB (Google Docs PDFs are ~100KB+ even for short docs) + pdftotext returns non-empty output + first paragraph matches the user's recollection.
Pitfalls
Multiple-account confusion.gws and gog may be authorized to different accounts on the same host (gws → service account; gog → personal). The active credentials vary by CLI. Confirm which account answered by reading the response's user.email (Gmail) or summary (Calendar) field, not by which CLI you invoked.
Service-account calendars show no events. A "calendarId=primary" call to gws returning items: [] and a firebase-adminsdk-… summary is the service account's empty calendar — not an auth error. Query the user's personal $USER@gmail.com calendar instead.
gog positional arg gotcha.gog calendar events list primary --days 2 parses primary as a subcommand. Use no positional arg for the default, or pass --calendar=… if supported; fall back to curl.
Don't paste the access token into logs. Echo ACCESS_TOKEN_LEN=${#ACCESS_TOKEN} instead of the raw value when running through a logged tool.
Don't run the full 5-step OAuth setup if gog/gws already work — read the stored credentials and use them. The user shouldn't have to re-authorize twice.
The bundled google-workspace skill is locked. You cannot patch its SKILL.md from a cron session. This skill is the user-editable mirror for the "Hermes not set up but a CLI is" branch.
