google-workspace — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited google-workspace (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
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/gmail-search-syntax.md — Gmail search operators (is:unread, from:, newer_than:, etc.)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.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:
GSETUP="python ${HERMES_HOME:-$HOME/.hermes}/skills/productivity/google-workspace/scripts/setup.py"$GSETUP --checkIf it prints AUTHENTICATED, skip to Usage — setup is already done.
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?"
himalaya skillinstead — 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.
--services email,calendar during auth so the consent screen only asks for the scopes they actually need.
narrower --services set like calendar,drive,sheets,docs.
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."
allowed apps list before Step 4 will work. Let them know upfront.
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: /home/user/Downloads/client_secret_....json
Once they provide the path:
$GSETUP --client-secret /path/to/client_secret.jsonIf 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.
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 jsonThis 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:
auth_url field and send that exact URL to the user as a single line.http://localhost:1 after approval, and that this is expected.Error 403: access_denied, send them directly to https://console.cloud.google.com/auth/audience to add themselves as a test user.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 jsonIf --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.
$GSETUP --checkShould print AUTHENTICATED. Setup is complete — token refreshes automatically from now on.
~/.hermes/google_token.json and auto-refreshes.~/.hermes/google_oauth_pending.json until exchange completes.gws is installed, google_api.py points it at the same ~/.hermes/google_token.json credentials file.
