description	Safe isolated testing environment for multi-agent swarm topologies before production deployment

Swarm Sandbox Simulator

When to activate

Before deploying multi-agent swarms with council.js to production
Testing agent interaction patterns, message flows, and error handling
Validating swarm topology configurations (2-agent, 5-agent, council-style)
Experimenting with new agent communication protocols
Sandboxing edge cases and failure scenarios in isolated environments
Validating safety guardrails and rate limits before live deployment

When NOT to use

Single-agent operations without inter-agent communication
Production deployments — use this for testing only, then migrate to live
Simple sequential agent pipelines — standard agent-construction skill is sufficient
One-off quick experiments without formal validation needs
Legacy monolithic systems without agent-based architecture

Instructions

Core concept

Swarm Sandbox creates an isolated, dry-run environment for testing multi-agent topologies. It validates:

Topology structure — agent count, relationships, message flow
Communication paths — request routing, response handling, cycles
Safety guardrails — rate limits, timeout handling, resource isolation
Error propagation — failure modes, recovery strategies, circuit breakers
Integration readiness — environment compatibility before production

Isolation validation checklist

## Pre-Deployment Validation Checklist

### Topology & Structure
- [ ] All agent IDs are unique and non-conflicting
- [ ] Agent role assignments align with responsibilities
- [ ] Communication topology matches documented design (hub-spoke, peer, linear)
- [ ] No circular dependencies in phase sequencing (if applicable)
- [ ] All agents have reachable endpoints in sandbox mock

### Communication & Messaging
- [ ] Message protocol defined and validated (JSON-RPC, gRPC, etc.)
- [ ] Serialization/deserialization tested for all message types
- [ ] Maximum message size limits enforced
- [ ] Routing rules tested for all agent pairs
- [ ] Cycle detection working for peer-to-peer topologies
- [ ] Message queuing and backpressure mechanisms validated

### Safety & Guardrails
- [ ] Rate limits enforced per agent and globally
- [ ] Timeout handling tested (graceful degradation vs. failure)
- [ ] Circuit breakers activate after N consecutive failures
- [ ] Memory isolation per agent sandboxed
- [ ] Resource limits (CPU, memory, token budget) enforced
- [ ] Network access restricted to mock endpoints only

### Error Handling & Recovery
- [ ] Retry logic tested with backoff (exponential, jitter)
- [ ] Fallback paths exist and are validated for critical failures
- [ ] Partial failure scenarios handled (e.g., 1 of 5 agents fails)
- [ ] Error messages logged with sufficient context
- [ ] No sensitive data in error outputs

### Performance & Scale
- [ ] Baseline latency measured for each agent
- [ ] Load test: validate behavior at 2x expected concurrent tasks
- [ ] Load test: validate behavior at 5x expected message rate
- [ ] Queue depth remains within limits under stress
- [ ] No memory leaks observed in extended runs

### Integration Readiness
- [ ] All external dependencies mocked (APIs, databases, file systems)
- [ ] Production environment variables documented
- [ ] Secrets management (API keys, auth tokens) not embedded in configs
- [ ] Agent discovery mechanism (if dynamic) tested in sandbox
- [ ] Graceful shutdown sequence verified

### Compliance & Audit
- [ ] All agent actions logged for audit trail
- [ ] Sensitive data (user IDs, PII) masked in logs
- [ ] Audit retention policy defined and enforced
- [ ] Compliance violations detected and reported
- [ ] Sandbox run reports generated automatically

Running the sandbox validator from CLI

# Initialize sandbox environment
source .swarm-sandbox.env
export SANDBOX_MODE=true

# Run topology validation
python3 swarm_sandbox_validator.py \
  --topology ./council-topology.json \
  --isolation-level strict \
  --output ./validation-report.json

# Run specific dry-run scenario
python3 swarm_sandbox_simulator.py \
  --topology ./council-topology.json \
  --scenario healthy_council \
  --metrics-output ./metrics.json \
  --trace-enabled

# Run chaos test (failure injection)
python3 swarm_sandbox_simulator.py \
  --topology ./council-topology.json \
  --chaos-mode true \
  --failure-rate-percent 10 \
  --failure-modes timeout,malformed_response \
  --output ./chaos-report.json

# Generate deployment readiness report
python3 swarm_sandbox_report.py \
  --validation ./validation-report.json \
  --metrics ./metrics.json \
  --output ./deployment-readiness.md

Integration with council.js

After sandbox validation passes, migrate to production:

// council.js controller integration
const council = require('council.js');
const sandboxReport = require('./.swarm-sandbox-report.json');

// Verify sandbox validation before deploying
if (sandboxReport.readiness !== 'green') {
  throw new Error('Sandbox validation failed. Fix issues before deployment.');
}

// Load production topology (same config as sandbox-validated)
const productionTopology = require('./council-topology.json');

// Initialize with guardrails from sandbox testing
const swarmController = council.create({
  topology: productionTopology,
  
  // Apply safety limits from sandbox
  rate_limits: productionTopology.agents.map(a => ({
    agent_id: a.id,
    requests_per_minute: a.rate_limit.requests_per_minute
  })),
  
  // Use timeout values from sandbox
  timeouts: productionTopology.agents.map(a => ({
    agent_id: a.id,
    timeout_ms: a.timeout_ms
  })),
  
  // Circuit breaker settings from sandbox
  circuit_breaker: productionTopology.communication.retry_policy.circuit_breaker,
  
  // Monitoring from sandbox metrics
  monitoring: {
    enabled: true,
    log_level: 'info',
    metrics_output: './production-metrics.json'
  }
});

// Deploy swarm
swarmController.start();
