Install & run

Setup Snapshot

git clone https://github.com/zhound420/a2a-agents-skill.git

1
Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

A2A Agents Skill

When to Use

Autonomous agent-to-agent communication
Running multi-agent swarms
Delegating complex tasks that benefit from multiple perspectives
Watching agent activity in real-time

Quick Commands

# Autonomous A2A — agent decides what help it needs
python3 ~/clawd/skills/a2a-agents/a2a_agent.py "Should we use Kubernetes for our startup?"

# Direct delegation to specialist
python3 ~/clawd/skills/a2a-agents/delegate.py researcher "Analyze the EV market"

Key Files

| File | Purpose | |------|---------| | a2a_agent.py | Core — Autonomous agent that calls other agents | | delegate.py | Direct delegation to specialist agents | | router.py | Unified agent calling interface | | kimi_agent.py | HTTP server wrapping Kimi/Ollama | | local_debate.py | Multi-agent debates | | tribunal.py | Structured multi-perspective analysis |

Models

Use for real work:

kimi-k2.5:cloud — Strong reasoning, best quality
deepseek-v3.1:cloud — DeepSeek flagship

Testing only:

llama3:8b — Fast but limited
phi3:mini — Very fast but shallow

Agent Monitor

Real-time dashboard showing agent activity:

open ~/clawd/agent-monitor/index.html

Important Notes

A2A = Autonomous: The agent decides when to call other agents — no human orchestration
Use local models for bulk work to avoid rate limits
All outputs go through QC before delivery to user
