assess options

Run stacktoit assess --help-all for the full option reference of the installed binary. The groups below explain the options commonly used in advanced projects.

Source and dependencies

Option	Meaning
--offline	Prohibit outbound network requests
--input auto|terraform|rvtools|bundle	Specify or detect source input type
--var-file FILE	Read an additional variable file; repeatable
--omitted-inputs FILE	Declare intentionally omitted source inputs
--provider-mirror DIR	Select a local provider mirror or plugin cache
--fetch-timeout DURATION	Set the remote module retrieval time budget
--validate-source	Require source validation with OpenTofu
--validate-proxy-env	Pass explicitly permitted proxy settings to validation and download processes

Target and financial model

Option	Meaning
--target-environment FILE	Supply target environment facts and constraints
--target-evidence ID=FILE	Provide target evidence referenced by the environment; repeatable
--validate	Require draft validation to run
--no-validate	Skip automatic OpenTofu validation
--price-cache DIR	Select a price-cache location
--assumptions FILE	Supply financial-model assumptions

Decisions, ownership and comparison

Option	Meaning
--inputs FILE	Supply typed design answers
--decisions FILE	Supply architect review records
--applications FILE	Supply explicit application groupings
--progress FILE	Supply a migration progress journal
--aws-inventory FILE	Compare source Terraform with a collected AWS inventory
--environment-id ID	Name the environment this source belongs to, so progress records stay bound to it

Project mode

Option	Meaning
--project DIR	Read a project from DIR/stacktoit.yaml
--profile NAME	Select the project profile

Project mode reads its source and relevant input files from the project definition; it cannot be mixed with positional source arguments.

Output and automation

Option	Meaning
--out DIR	Select the output directory
--replace	Replace previous generated content in a reused output folder
--keep-previous	Keep the previous run in OUT/previous-<run id>/ (the default)
--export-permissions private|shared	Control generated file permissions
--format text|json	Select human-readable or JSON Lines console output
--verbose	Print detailed engineering output after the summary
--strict	Return a non-zero code for partial or unverified results
--analysis-only	Write the assessment without the migration package

Older positive options such as --fetch-modules, --allow-incomplete and --convert are still accepted for compatibility with older scripts. For normal assessments, these behaviors are handled by default and do not need to be enabled.

Benchmark options

--units FILE and --blind support controlled benchmarks. They are not needed for a standard customer migration assessment.
