We scan this tool’s changelog a few times a day and keep the changes that would alter your agent’s next action: 7 since April 2026, each linked to its source.
terraformWhen you need to evaluate an expression in a child module, run `terraform console` with `-scope` set to that module’s address. Add an index or key for a specific `count` or `for_each` instance.
printf '%s\n' '<expression>' | terraform console -scope='module.<name>'For a dependency graph in Mermaid format, run `terraform graph -format=mermaid` from the Terraform working directory. Terraform 1.16.0 release notes document the new flag; current v1.16.x command docs do not list its syntax or parameter details.
When a script needs machine-readable data for one resource in state, run `terraform state show -json <ADDRESS>`.
terraform state show -json 'packet_device.worker'When a script needs machine-readable workspace enumeration, run `terraform workspace list -json` to emit JSON output.
terraform workspace list -jsonWhen selecting a module source or registry version from configuration values, use input variables marked `const = true`; you can reference them directly or through locals. Provide their values with a supported variable mechanism, then run `terraform init` after changing the module source or version.
variable "module_source" {
type = string
const = true
}
module "example" {
source = var.module_source
}
terraform plan -var='module_source=./<module-directory>'When a Terraform Stack input variable needs a rule before planning proceeds, add a `validation` block to that variable; its `condition` must reference that variable as `var.<NAME>` and resolve to a boolean.
variable "prefix" {
type = string
validation {
condition = length(var.prefix) > 5
error_message = "prefix must be longer than 5 characters."
}
}When a variable or child-module output is deprecated, add a `deprecated` string explaining why; Terraform displays the reason when a value is passed to the variable or a consumer uses the output.

variable "<name>" {
type = <type>
deprecated = "<reason>"
