crab params
Read or compare flattened parameter maps across Git refs.
Use show to inspect the resolved parameter values for one revision. Use
diff to find values that were added, removed, or changed between two
revisions. Crab flattens nested parameter documents into stable key paths, so
the output is useful for both terminal review and experiment automation.
Synopsis

show | Print the parameter map at a ref |
diff | Emit a structured parameter diff between refs |
crab params show --help
crab params diff --helpChoose a subcommand
Start with the subcommand help because selectors and output options belong to
show and diff, not to the parent command:
crab params show --help
crab params diff --helpA common review compares the current branch with its parent revision:
crab params show
crab params diff HEAD~1 HEADThe command reads parameter files through Git revisions; it does not execute
workflow stages or modify the workspace. Pair the result with
crab metrics diff to connect an input
change with a measured outcome. If a value is absent, confirm that its file is
declared as a workflow parameter source and exists at the selected ref.
