Use this skill when the user wants to send a Signal message or attachment to a person or group, even if they ask in terms of messaging someone rather than using signal-cli explicitly. It also applies when the user needs to set up or troubleshoot Signal CLI access, link Signal on a computer, or inspect Signal accounts, contacts, or groups.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# signal-cli Use the local `signal-cli` binary to send Signal messages and attachments. Account inspection, syncing, and recipient resolution support that primary workflow. ## Default workflow 1. Check whether `signal-cli` is installed and linked: ```bash command -v signal-cli signal-cli listAccounts ``` 2. If the binary is missing or `listAccounts` is empty, read `references/onboarding.md` and complete setup before trying to send anything. 3. Before listing contacts, listing groups, or sending, sync the account once: ```bash signal-cli -u "+15551234567" receive ``` 4. Use the bundled scripts for recipient resolution and sending: ```bash python3 scripts/find_contact.py --account "+15551234567" --query "Alice" python3 scripts/send_message.py --account "+15551234567" --to "Alice" --text "hello" python3 scripts/send_message.py --account "+15551234567" --to "Alice" --text "see attachment" --attachment "/path/to/file" ``` 5. If the user asks for raw CLI usage patterns beyond the defaults here, read `references/commands.md`. ## Defaults - Prefer linking `signal-cli` as a secondary device to the user's existing Signal account. …

How to install
mdr add brenorb/freedom-skills/signal-cli@sha256:523c8f13575e2a1bThe line at the top of this page pins the label git:20260513.275b3fa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
