mold upgrade¶

Update kit files to the latest version.

Usage¶

mold upgrade [flags]

Description¶

Reads .mold.toml to determine which kit, stack, and tools were used when the project was created, then compares each file against the latest embedded templates. User-modified files are preserved unless --force is used.

Flags¶

Flag	Default	Description
`--dry-run`	`false`	Preview changes without writing
`--force`	`false`	Overwrite user-modified files

Examples¶

Preview what would change:

mold upgrade --dry-run

Upgrade plan (dry run):

  = CLAUDE.md (unchanged)
  ~ .claude/settings.json (updated)
  + .claude/commands/refactor.md (new)
  ! docs/TODO.md (skipped — user-modified, use --force to overwrite)

Apply the upgrade:

mold upgrade

Force-overwrite modified files:

mold upgrade --force

Status indicators¶

Symbol	Meaning
`=`	File is unchanged, nothing to do
`~`	File will be updated to the latest template
`+`	New file that didn't exist before
`!`	Skipped because the file was modified by the user

Requirements¶

The current directory must contain a .mold.toml file, which is created automatically by mold new. Projects created with mold init also get this file.
