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. **Install:** ```bash npx degit https://github.com/davila7/claude-code-templates/tree/main/cli-tool/components/skills/ai-maestro/agent-messaging ~/.claude/skills/agent-messaging ``` ## README # 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](https://github.com/23blocks-OS/ai-maestro) suite. ## Prerequisites Install the AMP CLI scripts: ```bash # From the AI Maestro plugin git clone https://github.com/23blocks-OS/ai-maestro-plugins.git cd ai-maestro-plugins && ./install-messaging.sh -y ``` Scripts install to `~/.local/bin/` (ensure it's in your PATH). ## Quick Start ### 1. Initialize identity (first time) ```bash amp-init --auto ``` ### 2. Send a message ```bash amp-send alice "Hello" "How are you?" ``` ### 3. Check inbox ```bash amp-inbox ``` ### 4. Read a message ```bash amp-read ``` ### 5. Reply ```bash amp-reply "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 ` | Send a message | | `amp-inbox` | Check inbox (add `--all` for read messages) | | `amp-read ` | Read a specific message | | `amp-reply ` | Reply to a message | | `amp-delete ` | Delete a message | | `amp-status` | Show identity and registrations | | `amp-identity` | Show current identity | ## Message Options ```bash # 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.pdf ``` ## Message 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 ## Full AI Maestro Experience This skill provides basic AMP messaging. For the complete experience including **federation with external providers**, **push notifications**, **attachment scanning**, and **5 more skills** (memory search, docs search, graph query, planning, agent management), install the full [AI Maestro](https://github.com/23blocks-OS/ai-maestro) platform.
