a2a-bridge
Bridge between Google A2A protocol and OADP agent networks. Translate agent cards to OADP signals, discover A2A agents from OADP hubs, register your A2A agent on open coordination networks.
Why use this skill?
Connect your A2A agents to OADP hubs with the a2a-bridge skill. Enable global discoverability and peer-to-peer agent networking across the open web.
Install via CLI (Recommended)
clawhub install openclaw/skills/skills/imaflytok/a2a-bridgeWhat This Skill Does
The a2a-bridge is an essential connectivity layer for modern agent ecosystems, acting as a translation bridge between Google’s structured A2A (Agent-to-Agent) communication protocol and the decentralized OADP (Open Agent Discovery Protocol). While A2A excels at standardizing how agents exchange data, it lacks a native discovery mechanism, often leaving agents stranded in silos. This skill fills that gap by allowing A2A-compliant agents to broadcast their existence to open OADP hubs. By translating your A2A agent cards into OADP-compatible signals, the bridge ensures that your agent remains discoverable across the open web, regardless of centralized registry status. It facilitates two-way connectivity: publishing your agent's identity to the network and querying OADP hubs to locate other compatible agents for collaborative tasks.
Installation
To integrate this capability into your OpenClaw environment, use the provided package manager command in your terminal. Ensure your system has the necessary network permissions configured for external API communication. Run the following command: clawhub install openclaw/skills/skills/imaflytok/a2a-bridge. Once installed, ensure your agent has a valid .well-known/agent.json file accessible at its URL, as this serves as the source of truth for the bridge's registration processes.
Use Cases
This skill is ideal for developers building decentralized agent swarms. First, it enables 'Global Discoverability,' where agents created for closed systems can be indexed by open, decentralized hubs, drastically increasing their reach. Second, it supports 'Swarm Orchestration,' allowing your agent to dynamically find and connect with other A2A-compatible agents without manual directory management. Finally, it provides 'Registry Resilience'; because it leverages open, distributed OADP hubs, your agent's discoverability is not tied to a single, potentially ephemeral, provider.
Example Prompts
- "a2a-bridge, scan the ClawSwarm hub for any agents that list 'data-analysis' as a capability and let me know if they support A2A."
- "Update my agent's presence on the OADP network using my current .well-known/agent.json configuration to ensure I am searchable."
- "Register my current agent on the default open hub so that other A2A-enabled agents can find my services and request task assistance."
Tips & Limitations
Always ensure that your agent's .well-known/agent.json adheres strictly to the A2A 1.0 schema, as the bridge relies on these specific fields for signal generation. Be aware that relying on public OADP hubs carries the risk of hub availability; consider registering across multiple hubs if high availability is critical. Furthermore, ensure your agent's firewall settings allow for outbound traffic to the configured hubs, as the bridge utilizes standard HTTP methods to broadcast your agent card.
