Pilot Swarm Config

Distributed configuration management for agent swarms with versioned updates. Use this skill when: 1. Multiple agents need to share configuration settings 2. You need to push config updates to all swarm members 3. You want versioned config with rollback capability Do NOT use this skill when: - Configuration is static and set at startup (use local config files) - Each agent has unique config (no sharing needed)

Manage shared configuration across agent swarms with versioning, atomic updates, and rollback support.

Essential Commands

Publish configuration update

CONFIG_VERSION=$(date +%s)
CONFIG_DATA='{"max_workers":10,"timeout_ms":5000,"log_level":"info"}'

pilotctl --json publish "registry-hostname" "config:$SWARM_NAME" \
  --data "{\"type\":\"config_update\",\"version\":$CONFIG_VERSION,\"config\":$CONFIG_DATA}"

Subscribe to configuration updates

pilotctl --json subscribe "registry-hostname" "config:$SWARM_NAME"

Apply configuration locally

LATEST_CONFIG=$(pilotctl --json inbox \
  | jq '[.messages[] | select(.topic == "config:'$SWARM_NAME'" and .payload.type == "config_update")] | sort_by(.payload.version) | last')

CONFIG_VERSION=$(echo "$LATEST_CONFIG" | jq -r '.payload.version')
CONFIG_DATA=$(echo "$LATEST_CONFIG" | jq -r '.payload.config')

echo "$CONFIG_DATA" > /tmp/swarm-config.json
echo "$CONFIG_VERSION" > /tmp/swarm-config-version.txt

Validate configuration

# Basic validation
VALID=$(echo "$CONFIG_DATA" | jq 'has("max_workers") and has("timeout_ms")')

if [ "$VALID" = "true" ]; then
  echo "Config validation passed"
else
  echo "Config validation FAILED"
  exit 1
fi

Rollback to previous version

CURRENT_VERSION=$(cat /tmp/swarm-config-version.txt)
PREVIOUS_CONFIG=$(pilotctl --json inbox \
  | jq '[.messages[] | select(.topic == "config:'$SWARM_NAME'" and .payload.type == "config_update" and .payload.version < '$CURRENT_VERSION')] | sort_by(.payload.version) | last')

PREV_VERSION=$(echo "$PREVIOUS_CONFIG" | jq -r '.payload.version')
PREV_DATA=$(echo "$PREVIOUS_CONFIG" | jq -r '.payload.config')

echo "$PREV_DATA" > /tmp/swarm-config.json
echo "$PREV_VERSION" > /tmp/swarm-config-version.txt

Track compliance

# Agents report applied version
pilotctl --json publish "registry-hostname" "config:status:$SWARM_NAME" \
  --data "{\"agent\":\"$AGENT_ID\",\"applied_version\":$CONFIG_VERSION}"

# Coordinator checks compliance
COMPLIANCE=$(pilotctl --json inbox \
  | jq '[.messages[] | select(.topic == "config:status:'$SWARM_NAME'")] | group_by(.payload.applied_version) | map({version: .[0].payload.applied_version, count: length})')

Workflow Example

Agent config subscriber:

#!/bin/bash
set -e

SWARM_NAME="worker-pool"
CONFIG_CHANNEL="config:$SWARM_NAME"
STATUS_CHANNEL="config:status:$SWARM_NAME"
REGISTRY_HOST="registry.example.com"

pilotctl --json subscribe "$REGISTRY_HOST" "$CONFIG_CHANNEL"

CURRENT_VERSION=0
[ -f /tmp/swarm-config-version.txt ] && CURRENT_VERSION=$(cat /tmp/swarm-config-version.txt)

while true; do
  LATEST=$(pilotctl --json inbox \
    | jq '[.messages[] | select(.topic == "'$CONFIG_CHANNEL'" and .payload.type == "config_update")] | sort_by(.payload.version) | last')

  if [ -n "$LATEST" ] && [ "$LATEST" != "null" ]; then
    LATEST_VERSION=$(echo "$LATEST" | jq -r '.payload.version')

    if [ "$LATEST_VERSION" -gt "$CURRENT_VERSION" ]; then
      echo "Applying config version $LATEST_VERSION"
      CONFIG_DATA=$(echo "$LATEST" | jq -r '.payload.config')

      echo "$CONFIG_DATA" > /tmp/swarm-config.json
      echo "$LATEST_VERSION" > /tmp/swarm-config-version.txt

      # Report compliance
      pilotctl --json publish "$REGISTRY_HOST" "$STATUS_CHANNEL" \
        --data "{\"agent\":\"$AGENT_ID\",\"applied_version\":$LATEST_VERSION}"

      CURRENT_VERSION=$LATEST_VERSION
    fi
  fi
  sleep 5
done
