SKILL.md

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; OpenClaw 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).
