wacli
Send WhatsApp messages to other people or search/sync WhatsApp history via the wacli CLI (not for normal user chats).
Why this skill is useful
Provides specific commands and workflows for sending messages and syncing WhatsApp history that the AI wouldn't reliably generate on its own.
What it needs
Requires wacli installed locally. About 1k tokens when loaded. Last updated 2026-03-07. 639 stars on the source repository.
What this skill does
wacli Use wacli only when the user explicitly asks you to message someone else on WhatsApp or when they ask to sync/search WhatsApp history. Do NOT use wacli for normal user chats; Clawdbot routes WhatsApp conversations automatically. If the user is chatting with you on WhatsApp, you should not reach for this tool unless they ask you to contact a third party. Safety Require explicit recipient + message text. Confirm recipient + message before sending. If anything is ambiguous, ask a clarifying question. Auth + sync wacli auth (QR login + initial sync) wacli sync --follow (continuous sync) wacli doctor Find chats + messages wacli chats list --limit 20 --query "name or number" wacli messages search "query" --limit 20 --chat <jid> wacli messages search "invoice" --after 2025-01-01 --before 2025-12-31 History backfill wacli history backfill --chat <jid> --requests 2 --count 50 Send Text: wacli send text --to "+14155551212" --message "Hello! Are you free at 3pm?" Group: wacli send text --to "1234567890-123456789@g.us" --message "Running 5 min late." File: wacli send file --to "+14155551212" --file /path/agenda.pdf --caption "Agenda" Notes Store dir: ~/.wacli (override with --store). Use --json for machine-readable output when parsing. Backfill requires your phone online; results are best-effort. WhatsApp CLI is not needed for routine user chats; it’s for messaging other people. JIDs: direct chats look like <number>@s.whatsapp.net; groups look like <id>@g.us (use wacli chats list to find).
