Pilot A2a Bridge

Bridge A2A (Agent-to-Agent) protocol messages over Pilot tunnels. Use this skill when: 1. You need to connect A2A agents across different networks 2. You wan...

Security Scan

The skill's requests and runtime instructions are consistent with its stated purpose (bridging A2A messages via the pilotctl daemon) and there are no unexplained credentials, installs, or persistence demands.

Purpose & Capability

Name/description match the requested resources: the skill is an instruction-only bridge that expects the pilotctl binary and a running pilot daemon, which is coherent for bridging A2A messages across networks.

Instruction Scope

Instructions stay within the stated purpose (starting daemon, listen/send/recv/subscribe). Minor omissions: the example scripts assume jq and a process_task function that are not declared; the skill instructs agents to send arbitrary JSON payloads, which is expected for messaging but also means the skill can carry any data the agent provides (normal for a messaging bridge).

Install Mechanism

No install spec and no code files (instruction-only) — nothing is downloaded or written to disk by the skill itself, which is low risk.

Credentials

The skill requires no environment variables or credentials. It only needs the pilotctl binary and a running daemon, which is proportionate to its purpose.

Persistence & Privilege

always:false and no special privileges requested. The skill does not request permanent presence or modify other skills' configs.

Assessment

This skill appears coherent, but review these practical points before installing: 1) Verify pilotctl is the official binary from pilotprotocol.network (a messaging bridge can forward any data, so you must trust the binary and daemon). 2) The examples use jq and reference a process_task function — ensure your runtime has jq or adapt the scripts and implement secure handling of received payloads. 3) Because it enables agent-to-agent messaging, avoid sending secrets or sensitive files through the bridge and consider running it in a network-isolated environment or with strict policies. 4) Confirm you also trust the required pilot-protocol skill and any remote agents you’ll connect to.

Commands

Start A2A Bridge

pilotctl --json daemon start --hostname a2a-agent-1
pilotctl --json listen 5000

Send A2A Message

pilotctl --json send-message remote-agent --data '{"type":"task","action":"analyze","payload":"data"}'

Subscribe to A2A Events

pilotctl --json subscribe remote-agent a2a-events

Receive A2A Messages

pilotctl --json recv 5000

Workflow Example

#!/bin/bash
# Agent A: A2A bridge listener

pilotctl --json daemon start --hostname agent-a
pilotctl --json listen 5000

while true; do
  MSG=$(pilotctl --json recv 5000 --timeout 30s)
  TYPE=$(echo "$MSG" | jq -r '.type')
  SENDER=$(echo "$MSG" | jq -r '.sender')

  case "$TYPE" in
    task)
      RESULT=$(process_task "$(echo "$MSG" | jq -r '.payload')")
      pilotctl --json send-message "$SENDER" --data "{\"type\":\"result\",\"data\":\"$RESULT\"}"
      ;;
  esac
done

Message Format

{
  "type": "task|result|event|status",
  "action": "analyze|process|compute",
  "payload": "arbitrary data"
}

Dependencies

Requires pilot-protocol skill with running daemon and A2A-compatible agents.
