Google Workspace

Gmail, Calendar, Drive, Contacts, Sheets, and Docs — powered by gws (Google's official Rust CLI). The skill provides a backward-compatible Python wrapper that handles OAuth token refresh and delegates to gws.

Architecture

google_api.py  →  gws_bridge.py  →  gws CLI
(argparse compat)  (token refresh)    (Google APIs)

• setup.py handles OAuth2 (headless-compatible, works on CLI/Telegram/Discord)
• gws_bridge.py refreshes the Hermes token and injects it into gws via GOOGLE_WORKSPACE_CLI_TOKEN
• google_api.py provides the same CLI interface as v1 but delegates to gws

References

• references/gmail-search-syntax.md — Gmail search operators (is:unread, from:, newer_than:, etc.)

Scripts

• scripts/setup.py — OAuth2 setup (run once to authorize)
• scripts/gws_bridge.py — Token refresh bridge to gws CLI
• scripts/google_api.py — Backward-compatible API wrapper (delegates to gws)

Prerequisites

Install gws:

cargo install google-workspace-cli
# or via npm (recommended, downloads prebuilt binary):
npm install -g @googleworkspace/cli
# or via Homebrew:
brew install googleworkspace-cli

Verify: gws --version

First-Time Setup

The setup is fully non-interactive — you drive it step by step so it works on CLI, Telegram, Discord, or any platform.

Define a shorthand first:

HERMES_HOME="${HERMES_HOME:-$HOME/.hermes}"
GWORKSPACE_SKILL_DIR="$HERMES_HOME/skills/productivity/google-workspace"
PYTHON_BIN="${HERMES_PYTHON:-python3}"
if [ -x "$HERMES_HOME/hermes-agent/venv/bin/python" ]; then
  PYTHON_BIN="$HERMES_HOME/hermes-agent/venv/bin/python"
fi
GSETUP="$PYTHON_BIN $GWORKSPACE_SKILL_DIR/scripts/setup.py"

Step 0: Check if already set up

$GSETUP --check

If it prints AUTHENTICATED, skip to Usage — setup is already done.

Step 1: Triage — ask the user what they need

Question 1: "What Google services do you need? Just email, or also Calendar/Drive/Sheets/Docs?"

• Email only → Use the himalaya skill instead — simpler setup.
• Calendar, Drive, Sheets, Docs (or email + these) → Continue below.

Partial scopes: Users can authorize only a subset of services. The setup script accepts partial scopes and warns about missing ones.

Question 2: "Does your Google account use Advanced Protection?"

• No / Not sure → Normal setup.
• Yes → Workspace admin must add the OAuth client ID to allowed apps first.

Step 2: Create OAuth credentials (one-time, ~5 minutes)

Tell the user:

1. Go to https://console.cloud.google.com/apis/credentials
2. Create a project (or use an existing one)
3. Enable the APIs you need (Gmail, Calendar, Drive, Sheets, Docs, People)
4. Credentials → Create Credentials → OAuth 2.0 Client ID → Desktop app
5. Download JSON and tell me the file path

$GSETUP --client-secret /path/to/client_secret.json

Step 3: Get authorization URL

$GSETUP --auth-url

Send the URL to the user. After authorizing, they paste back the redirect URL or code.

Step 4: Exchange the code

$GSETUP --auth-code "THE_URL_OR_CODE_THE_USER_PASTED"

Step 5: Verify

$GSETUP --check

Should print AUTHENTICATED. Token refreshes automatically from now on.

Usage

All commands go through the API script:

HERMES_HOME="${HERMES_HOME:-$HOME/.hermes}"
GWORKSPACE_SKILL_DIR="$HERMES_HOME/skills/productivity/google-workspace"
PYTHON_BIN="${HERMES_PYTHON:-python3}"
if [ -x "$HERMES_HOME/hermes-agent/venv/bin/python" ]; then
  PYTHON_BIN="$HERMES_HOME/hermes-agent/venv/bin/python"
fi
GAPI="$PYTHON_BIN $GWORKSPACE_SKILL_DIR/scripts/google_api.py"

Gmail

$GAPI gmail search "is:unread" --max 10
$GAPI gmail get MESSAGE_ID
$GAPI gmail send --to [e-mail] --subject "Hello" --body "Message text"
$GAPI gmail send --to [e-mail] --subject "Report" --body "<h1>Q4</h1>" --html
$GAPI gmail reply MESSAGE_ID --body "Thanks, that works for me."
$GAPI gmail labels
$GAPI gmail modify MESSAGE_ID --add-labels LABEL_ID

Calendar

$GAPI calendar list
$GAPI calendar create --summary "Standup" --start 2026-03-01T10:00:00+01:00 --end 2026-03-01T10:30:00+01:00
$GAPI calendar create --summary "Review" --start ... --end ... --attendees "[e-mail],[e-mail]"
$GAPI calendar delete EVENT_ID

Drive

$GAPI drive search "quarterly report" --max 10
$GAPI drive search "mimeType='application/pdf'" --raw-query --max 5

Contacts

$GAPI contacts list --max 20

Sheets

$GAPI sheets get SHEET_ID "Sheet1!A1:D10"
$GAPI sheets update SHEET_ID "Sheet1!A1:B2" --values '[["Name","Score"],["Alice","95"]]'
$GAPI sheets append SHEET_ID "Sheet1!A:C" --values '[["new","row","data"]]'

Docs

$GAPI docs get DOC_ID

Direct gws access (advanced)

For operations not covered by the wrapper, use gws_bridge.py directly:

GBRIDGE="$PYTHON_BIN $GWORKSPACE_SKILL_DIR/scripts/gws_bridge.py"
$GBRIDGE calendar +agenda --today --format table
$GBRIDGE gmail +triage --labels --format json
$GBRIDGE drive +upload ./report.pdf
$GBRIDGE sheets +read --spreadsheet SHEET_ID --range "Sheet1!A1:D10"

Output Format

All commands return JSON via gws --format json. Key output shapes:

• Gmail search/triage: Array of message summaries (sender, subject, date, snippet)
• Gmail get/read: Message object with headers and body text
• Gmail send/reply: Confirmation with message ID
• Calendar list/agenda: Array of event objects (summary, start, end, location)
• Calendar create: Confirmation with event ID and htmlLink
• Drive search: Array of file objects (id, name, mimeType, webViewLink)
• Sheets get/read: 2D array of cell values
• Docs get: Full document JSON (use body.content for text extraction)
• Contacts list: Array of person objects with names, emails, phones

Parse output with jq or read JSON directly.

Rules

1. Never send email or create/delete events without confirming with the user first.
2. Check auth before first use — run setup.py --check.
3. Use the Gmail search syntax reference for complex queries.
4. Calendar times must include timezone — ISO 8601 with offset or UTC.
5. Respect rate limits — avoid rapid-fire sequential API calls.

Troubleshooting

Problem	Fix
NOT_AUTHENTICATED	Run setup Steps 2-5
REFRESH_FAILED	Token revoked — redo Steps 3-5
gws: command not found	Install: npm install -g @googleworkspace/cli
HttpError 403	Missing scope — $GSETUP --revoke then redo Steps 3-5
HttpError 403: Access Not Configured	Enable API in Google Cloud Console
Advanced Protection blocks auth	Admin must allowlist the OAuth client ID

Revoking Access

$GSETUP --revoke
