Google Workspace

Gmail, Calendar, Drive, Contacts, Sheets, and Docs — through Hermes-managed OAuth and a thin CLI wrapper. When gws is installed, the skill uses it as the execution backend for broader Google Workspace coverage; otherwise it falls back to the bundled Python client implementation.

References

• references/gmail-search-syntax.md — Gmail search operators (is:unread, from:, newer_than:, etc.)
• references/daily-brief.md — daily/morning brief procedure: schedule + conflicts + meeting prep + urgent mail from Gmail and Calendar. Load it when the user asks for a morning brief, meeting preparation, or "what's on my calendar and what email needs attention."

Scripts

• scripts/setup.py — OAuth2 setup (run once to authorize)
• scripts/google_api.py — compatibility wrapper CLI. It prefers gws for operations when available, while preserving Hermes' existing JSON output contract.

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.

Run the setup script with Python from the Hermes environment, not an unrelated system Python. --install-deps syncs Hermes' declared Google extra through PM; after syncing, restart Hermes and rerun the OAuth command. If Hermes is not importable, use hermes setup first rather than installing packages with pip.

Define a shorthand first:

GSETUP="python ${HERMES_HOME:-$HOME/.hermes}/skills/productivity/google-workspace/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

Before starting OAuth setup, ask the user TWO questions:

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

• Email only → They don't need this skill at all. Use the himalaya skill

instead — it works with a Gmail App Password (Settings → Security → App Passwords) and takes 2 minutes to set up. No Google Cloud project needed. Load the himalaya skill and follow its setup instructions.

• Email + Calendar → Continue with this skill, but use

--services email,calendar during auth so the consent screen only asks for the scopes they actually need.

• Calendar/Drive/Sheets/Docs only → Continue with this skill and use a

narrower --services set like calendar,drive,sheets,docs.

• Full Workspace access → Continue with this skill and use the default

all service set.

Question 2: "Does your Google account use Advanced Protection (hardware security keys required to sign in)? If you're not sure, you probably don't — it's something you would have explicitly enrolled in."

• No / Not sure → Normal setup. Continue below.
• Yes → Their Workspace admin must add the OAuth client ID to the org's

allowed apps list before Step 4 will work. Let them know upfront.

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

Tell the user:

You need a Google Cloud OAuth client. This is a one-time setup:

1. Create or select a project:

https://console.cloud.google.com/projectselector2/home/dashboard

2. Enable the required APIs from the API Library:

https://console.cloud.google.com/apis/library

Enable: Gmail API, Google Calendar API, Google Drive API,

Google Sheets API, Google Docs API, People API

3. Create the OAuth client here:

https://console.cloud.google.com/apis/credentials

Credentials → Create Credentials → OAuth 2.0 Client ID

4. Application type: "Desktop app" → Create

5. If the app is still in Testing, add the user's Google account as a test user here:

https://console.cloud.google.com/auth/audience

Audience → Test users → Add users

6. Download the JSON file and tell me the file path

Important Hermes CLI note: if the file path starts with /, do NOT send only the bare path as its own message in the CLI, because it can be mistaken for a slash command. Send it in a sentence instead, like:

The JSON file path is: ~/Downloads/client_secret_....json

Once they provide the path:

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

If they paste the raw client ID / client secret values instead of a file path, write a valid Desktop OAuth JSON file for them yourself, save it somewhere explicit (for example ~/Downloads/hermes-google-client-secret.json), then run --client-secret against that file.

Step 3: Get authorization URL

Use the service set chosen in Step 1. Examples:

$GSETUP --auth-url --services email,calendar --format json
$GSETUP --auth-url --services calendar,drive,sheets,docs --format json
$GSETUP --auth-url --services all --format json

This returns JSON with an auth_url field and also saves the exact URL to ~/.hermes/google_oauth_last_url.txt.

Agent rules for this step:

• Extract the auth_url field and send that exact URL to the user as a single line.
• Tell the user that the browser will likely fail on http://localhost:1 after approval, and that this is expected.
• Tell them to copy the ENTIRE redirected URL from the browser address bar.
• If the user gets Error 403: access_denied, send them directly to https://console.cloud.google.com/auth/audience to add themselves as a test user.

Step 4: Exchange the code

The user will paste back either a URL like http://localhost:1/?code=4/0A...&scope=... or just the code string. Either works. The --auth-url step stores a temporary pending OAuth session locally so --auth-code can complete the PKCE exchange later, even on headless systems:

$GSETUP --auth-code "THE_URL_OR_CODE_THE_USER_PASTED" --format json

If --auth-code fails because the code expired, was already used, or came from an older browser tab, it now returns a fresh fresh_auth_url. In that case, immediately send the new URL to the user and have them retry with the newest browser redirect only.

Step 5: Verify

$GSETUP --check

Should print AUTHENTICATED. Setup is complete — token refreshes automatically from now on.

Notes

• Token is stored at ~/.hermes/google_token.json and auto-refreshes.
• Pending OAuth session state/verifier are stored temporarily at ~/.hermes/google_oauth_pending.json until exchange completes.
• If gws is installed, google_api.py points it at the same ~/.hermes/google_token.json credentials file. Users do not need to run a separate gws auth login flow.
• To revoke: $GSETUP --revoke
