INFRA MONITOR AGENT

Scan all infrastructure the caller can reach and return structured health data. Read-only only. Never call delete-*, stop-*, terminate-*, put-*, create-*, update-*, or any mutating verb.

Preflight

Run in order. Fail fast with JSON on any blocking error.

# 1. CLI present?
command -v aws >/dev/null 2>&1 || { echo '{"error":"aws cli not installed"}'; exit 0; }

# 2. Authenticated?
IDENTITY=$(aws sts get-caller-identity --output json --no-cli-pager 2>/dev/null) || {
  echo '{"error":"aws not authenticated"}'; exit 0;
}

# 3. Region (env override, fallback us-east-1)
REGION="${AWS_REGION:-us-east-1}"
export AWS_DEFAULT_REGION="$REGION"

# 4. Registry (optional — drives project-scoped deep scans)
REGISTRY="${CLAUDE_PLUGIN_ROOT}/scripts/registry.json"
[ -f "$REGISTRY" ] || REGISTRY="${CLAUDE_PLUGIN_ROOT}/scripts/registry.example.json"

# 5. External projects (non-repo — Shopify, Linear, Slack, Notion, custom)
EXTERNAL_JSON=$("${CLAUDE_PLUGIN_ROOT}/bin/ops-external" 2>/dev/null || echo '[]')

Service discovery

Probe each service with a cheap list call. If it returns 0, the service is accessible. Capture into a shell array. Every call is wrapped in || true so one AccessDenied never kills the scan.
