What it does
Agent Messaging is an agent skill from davila7/claude-code-templates. Send and receive cryptographically signed messages between AI agents using the Agent Messaging Protocol (AMP). Use when the user asks to "send a message to an agent", "check agent inbox", "message another agent", "reply to a message", "notify an agent", or any inter-agent communication task.
Its SKILL.md is about 810 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 Mobile, covering Email management and Mobile testing and debugging. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.
When your agent uses it
- The user asks to send a message to an agent
- Check agent inbox
- Message another agent
- Reply to a message
Example prompts
- “send a message to an agent”
- “check agent inbox”
- “message another agent”
- “/agent-messaging”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 4c82aba. 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
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
github.com
Also links to:
agentmessaging.org
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
Agent Messaging loads about 807 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 244 words of instructions outside code blocks.
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.

Prerequisites
Install the AMP CLI scripts:
# From the AI Maestro plugin
git clone https://github.com/23blocks-OS/ai-maestro-plugins.git
cd ai-maestro-plugins && ./install-messaging.sh -yScripts install to ~/.local/bin/ (ensure it's in your PATH).
Quick Start
1. Initialize identity (first time)
amp-init --auto2. Send a message
amp-send alice "Hello" "How are you?"3. Check inbox
amp-inbox4. Read a message
amp-read <message-id>5. Reply
amp-reply <message-id> "Got it, working on it now"Address Formats
| Format | Example | Delivery |
|---|---|---|
| Local name | alice | Same machine |
| Local qualified | alice@myorg.aimaestro.local | Within mesh |
| External | alice@acme.crabmail.ai | Via provider (requires registration) |
Core Commands
| Command | Description |
|---|---|
amp-init --auto | Create agent identity |
amp-send <to> <subject> <body> | Send a message |
amp-inbox | Check inbox (add --all for read messages) |
amp-read <id> | Read a specific message |
amp-reply <id> <body> | Reply to a message |
amp-delete <id> | Delete a message |
amp-status | Show identity and registrations |
amp-identity | Show current identity |
Message Options
# Set priority
amp-send alice "Deploy" "Ready for prod" --priority urgent
# Set type
amp-send alice "Review PR #42" "Please review" --type request
# Attach files
amp-send alice "Report" "See attached" --attach report.pdfMessage Types and Priorities
| Type | Use Case | Priority | When | |
|---|---|---|---|---|
notification | General info (default) | normal | Standard (default) | |
request | Asking for something | urgent | Immediate attention | |
task | Assigned work | high | Respond soon | |
handoff | Transferring context | low | When convenient | |
status | Progress update |
Security
- Ed25519 signatures on every message
- Private keys stay local -- never sent to providers
