Module update 

Structs

UpdateParams

Prepared parameters for workflow update — the system prompt, initial user prompt, and the staging path that the agent should edit in place.

Enums

WorkflowKind

File kind on disk — either a plain .zwf TOML file or a zipped .zwfz archive. Determines how the binary stages the workflow for editing and how it writes it back when the agent session ends.

Functions

prepare_update

Prepare an update session without launching zag. Resolves the workflow, copies or unzips it to a tempdir, validates that it parses, and builds the system + initial prompts.

run_update

Launch an interactive zag session for workflow revision.
