signal-cli – OpenClaw Skill

---

name: signal-cli description: Send Signal messages and look up Signal recipients via the local signal-cli installation on macOS. Use when the user asks to message someone on Signal, send a Signal text/attachment, list Signal contacts, or resolve a recipient by name/nickname/phone number.

signal-cli (Signal Messaging)

Use the local signal-cli binary.

Preconditions

• signal-cli is installed and already linked/registered.
• For safety: confirm recipient + final message text with the user before sending.

Quick patterns

Discover available accounts

signal-cli listAccounts

List contacts (JSON)

signal-cli -o json -u "+386..." listContacts

Find a contact by name/nickname/number

Prefer the bundled script (handles fuzzy-ish matching + multiple matches):

python3 scripts/find_contact.py --account "+386..." --query "Name"

Send a message

Prefer the bundled script (resolves contact names to numbers):

python3 scripts/send_message.py --account "+386..." --to "Name" --text "Heyo ..."

If --to is already a phone number in E.164 (e.g. +386...), it sends directly.

Safety checklist (always)

• If resolving by name returns multiple matches, present options and ask the user which one.
• If message contains sensitive info, ask explicitly before sending via Signal.
• Default to --service-environment live (signal-cli default) and normal trust behavior.
