At a glance

Send and read messages via imsg (iMessage) and wacli (WhatsApp).

  • Tasks that involve Messaging and chat bots
  • SKILL.md covers iMessage & SMS — imsg, WhatsApp — wacli, Usage Guidelines and Notes
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

C Messaging is an agent skill from daxaur/openpaw. Send and read messages via imsg (iMessage) and wacli (WhatsApp). Supports sending to individuals or groups, reading recent conversations, and checking unread messages across both platforms.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Productivity & Automation, covering Messaging and chat bots. It works with WhatsApp. The repository describes itself as: Personal Assistant Wizard for Claude Code — npx pawmode. The licence is MIT.

When your agent uses it

  • Tasks that involve Messaging and chat bots

Example prompts

  • “/c-messaging”

What it can do on your machine

Read from SKILL.md and the folder at commit a2562d1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

C Messaging loads about 568 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 106 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~568

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

iMessage & SMS — imsg

bash
imsg send "Phone or Email" "Message text"  # Send a message
imsg send "+14155551234" "Hello!"
imsg send "user@icloud.com" "Hey there"
imsg list                                   # List recent conversations
imsg list --limit 10                        # Last 10 conversations
imsg read "+14155551234"                    # Read conversation with contact
imsg read "+14155551234" --limit 20         # Read last 20 messages
imsg unread                                 # Show unread messages
imsg group send "Group Name" "Message"      # Send to a group chat
imsg group list                             # List group chats
imsg contacts                               # List contacts

WhatsApp — wacli

bash
wacli send "+14155551234" "Message text"    # Send a message
wacli send "Contact Name" "Hello!"          # Send by name (if in contacts)
wacli list                                  # List recent chats
wacli read "+14155551234"                   # Read conversation
wacli read "+14155551234" --limit 20
wacli unread                                # Show unread messages
wacli group list                            # List WhatsApp groups
wacli group send "Group Name" "Message"
wacli status "Your status text"            # Set WhatsApp status

Usage Guidelines

  • Use imsg for iMessage/SMS to Apple devices or phone numbers.
  • Use wacli for WhatsApp contacts.
  • Phone numbers should include country code (e.g., +1 for US).
  • Check imsg unread or wacli unread before sending follow-ups.
  • If a contact name is ambiguous, prefer using the phone number directly.

Notes

  • imsg requires macOS and an active iMessage account.
  • wacli requires WhatsApp to be linked — run wacli auth to scan QR code on first use.
  • Both tools operate locally; no cloud API credentials required after initial auth.
