Omriariav Workspace CLI Chat

Google Chat (gws chat)

gws chat provides CLI access to Google Chat with structured JSON output.

Disclaimer: gws is not the official Google CLI. This is an independent, open-source project not endorsed by or affiliated with Google.

Dependency Check

Before executing any gws command, verify the CLI is installed:

gws version

If not found, install: go install github.com/omriariav/workspace-cli/cmd/gws@latest

Authentication

Requires OAuth2 credentials. Run gws auth status to check. If not authenticated: gws auth login (opens browser for OAuth consent). For initial setup, see the gws-auth skill.

Note: Google Chat API requires additional setup:

1. Enable the Chat API in your Google Cloud project
2. Configure the OAuth consent screen for Chat scopes
3. For some operations, you may need a service account with domain-wide delegation

Common Mistakes

Recipe: Find a Group Chat by Member Names

Preferred method — use the member cache:

# 1. Build the cache (one-time, or periodically)
gws chat build-cache

# 2. Search by email
gws chat find-group --members "alice@example.com,bob@example.com"

# 3. Get recent messages from the matched space
gws chat messages spaces/AAAApznBCFA --after "2026-02-20T00:00:00Z" --order-by "createTime DESC" --max 25

Alternative — manual search (no cache needed):

# 1. List all spaces, filter to group chats
gws chat list --format json | jq '.spaces | map(select(.type == "GROUP_CHAT")) | .[:10]'

# 2. Check members of candidate spaces
gws chat members spaces/AAAApznBCFA --format json

Key insight: DMs and group chats often have empty display_name — you must check members to identify participants.

Recipe: Create a DM via Contacts

# 1. Resolve email to user resource name
gws contacts resolve --email "user@example.com"

# 2. Check if DM already exists
gws chat find-dm --user users/123456

# 3. If not found, create the DM
gws chat setup-space --type DIRECT_MESSAGE --members "users/123456"

# 4. Send a message
gws chat send --space spaces/DMXYZ --text "Hello!"

Tips for AI Agents

• Always use --format json (the default) for programmatic parsing
• Use gws chat list first to get space IDs
• Space IDs are in the format spaces/AAAA1234
• Message names are in the format spaces/AAAA/messages/msg1
• members auto-resolves display names via People API — first call may be slower, subsequent calls use cache
• Use --order-by "createTime DESC" with messages to get newest first
• Use --filter 'createTime > "YYYY-MM-DDT00:00:00Z"' to scope messages to a date range — more reliable than relying on default ordering
• read-state auto-expands bare space IDs (e.g. AAAA → users/me/spaces/AAAA/spaceReadState)
• events requires a --filter with event types — see API docs
• Chat API requires additional GCP setup beyond standard OAuth — see the gws-auth skill
