SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill acts as the sole intermediary for all communication within the SeedClaw agent swarm, preventing direct skill-to-skill interaction and enforcing a secure, auditable communication channel.

Core Features & Use Cases

  • Centralized Routing: Manages all message traffic between skills and the SeedClaw core.
  • Sender Validation: Ensures messages originate from authenticated skills.
  • Schema Enforcement: Validates incoming messages against a defined JSON structure.
  • Immutable Auditing: Logs every transaction for a transparent audit trail.
  • Network Isolation: Enforces strict network policies, blocking all outbound internet access and direct inter-container communication.
  • Use Case: When the 'coder' skill needs to send a generated code snippet to the 'llm-caller' skill, it sends the message to the 'message-hub', which then validates and forwards it, ensuring all communication adheres to the platform's security protocols.

Quick Start

Instruct the message hub skill to route a JSON message containing a 'task' payload from 'user-agent' to 'llm-caller'.

Frequently Asked Questions about Message Hub Skill

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I centralize inter-skill communication routing in an agent swarm?

Centralize inter-skill communication routing by using a control plane gateway that acts as the sole intermediary, mandating all messages pass through it rather than allowing direct skill-to-skill interaction. This enforces secure, structured JSON messaging.

How does sender validation work for IPC routing?

Sender validation for IPC routing works by verifying that every incoming structured JSON message originates from an authenticated skill before forwarding it. This ensures unauthorized agents cannot inject traffic into the agent swarm.

How do I log inter-skill communication for auditing purposes?

Log inter-skill communication for auditing by routing all transaction traffic through a central message hub that records every message to an immutable audit trail, ensuring a transparent and verifiable history of all interactions.

Can I block outbound internet access for inter-skill communication?

Yes, you can block outbound internet access by enforcing strict network isolation policies within the message hub. This prevents direct inter-container communication and restricts all external network egress for security.

What is the best way to enforce JSON schema validation across skill messages?

The best way to enforce JSON schema validation is to route all payloads through a centralized IPC router. The router validates incoming messages against a defined JSON structure before forwarding them to the target skill.

Why prevent direct skill-to-skill communication in an agent platform?

Preventing direct skill-to-skill communication eliminates unmonitored network paths, ensuring all interactions adhere to platform security protocols. This centralized routing enables strict sender validation and comprehensive transaction auditing.
