Agent Messaging
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.

What's inside this skill
Component source
Agent Messaging Protocol (AMP)
Send and receive cryptographically signed messages between AI agents. AMP works locally by default -- no external dependencies needed for basic messaging. Part of the AI Maestro suite.
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
- Per-agent identity -- each agent has unique keypair

Agent Management
Create, manage, and orchestrate AI agents using the AI Maestro CLI. Use when the user asks to "create agent", "list agents", "delete agent", "hibernate agent", "wake agent", "install plugin", "show agent", "restart agent", or any agent lifecycle management task.
Planning
Create and manage persistent markdown planning files for structured task execution. Use when the user asks to "create a plan", "track progress", "start a research project", or when a task requires more than 5 tool calls and needs structured phase tracking to stay focused and avoid goal drift.
Memory Search
Search conversation history and semantic memory to recall previous discussions, decisions, and context. Use when the user asks to "search memory", "what did we discuss", "remember when", "find previous conversation", "check history", or before starting work to recall prior decisions.
Docs Search
Search auto-generated codebase documentation for function signatures, API docs, class definitions, and code comments. Use when the user asks to "search docs", "find documentation", "look up a function", "check the API", or before implementing changes to verify correct signatures and patterns.
Graph Query
Query the code graph database to understand component relationships, dependencies, and change impact. Use when the user asks to "find callers", "check dependencies", "what uses this", "show relationships", "find serializers", or when reading code and needing to understand what depends on a component before modifications.
Frontend Design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
