references/MANUAL-IMPORT.mdscripts/list_resources.shGuides browser automation with Playwright, Puppeteer, Selenium for e2e testing and scraping. Teaches reliable selectors, auto-waits, isolation to fix flaky tests.
Provides checklists to review code for functionality, quality, security, performance, tests, and maintainability. Use for PRs, audits, team standards, and developer training.
Enforces A/B test setup with gates for hypothesis locking, metrics definition, sample size calculation, assumptions checks, and execution readiness before implementation.
Discover existing cloud resources using declarative queries and generate configuration for bulk import into Terraform state.

BEFORE starting, you MUST verify the target resource type is supported:
# Check what list resources are available
./scripts/list_resources.sh aws # Specific provider
./scripts/list_resources.sh # All configured providers
Identify target resource type (e.g., aws_s3_bucket, aws_instance)
Check if supported: Run ./scripts/list_resources.sh <provider>
Choose workflow:
Note: The list of supported resources is rapidly expanding. Always verify current support before using manual import.
Before writing queries, verify the provider supports list resources for your target resource type.
Run the helper script to extract supported list resources from your provider:
# From a directory with provider configuration (runs terraform init if needed)
./scripts/list_resources.sh aws # Specific provider
./scripts/list_resources.sh # All configured providers
Or manually query the provider schema:
terraform providers schema -json | jq '.provider_schemas | to_entries | map({key: (.key | split("/")[-1]), value: (.value.list_resource_schemas // {} | keys)})'
Terraform Search requires an initialized working directory. Ensure you have a configuration with the required provider before running queries:
# terraform.tf
terraform {
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 6.0"
}
}
}
Run terraform init to download the provider, then proceed with queries.

Provider support for list resources varies by version. Always check what's available for your specific provider version using the discovery script.
# Find all EC2 instances in configured region
list "aws_instance" "all" {
provider = aws
}
# Find instances by tag

Columns: <query_address> <identity_attributes> <name_tag>
The -generate-config-out flag creates:
# __generated__ by Terraform
resource "aws_instance" "all_0" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
# ... all attributes
}
import {
to = aws_instance.all_0
provider = aws
identity = {
account_id = "123456789012"
id = "i-0abc123"
region = "us-west-2"
}
}
Generated configuration includes all attributes. Clean up by:
# Before: generated
resource "aws_instance" "all_0" {
ami = "ami-0c55b159cbfafe1f0"
instance_type = "t2.micro"
arn = "arn:aws:ec2:..." # Remove - computed
id = "i-0abc123" # Remove - computed
# ... many more attributes
}
# After: cleaned
resource "aws_instance" "web_server" {
ami = var.ami_id
instance_type = var.instance_type
subnet_id = var.subnet_id
tags = {
Name = "web-server"
Environment = var.environment
}
}
Generated imports use identity-based import (Terraform 1.12+):
import {
to = aws_instance.web
provider = aws
identity = {
account_id = "123456789012"
id = "i-0abc123"
region = "us-west-2"
}
}
limit to prevent overwhelming output| Issue | Solution |

| Query returns empty | Verify region and filter values |
| Generated config has errors | Remove computed attributes, fix deprecated arguments |
