Use cases
Every locale, one mission.
Internationalization is parallel work disguised as one long chore. Loom splits string extraction, locale wiring, and surface-by-surface translation across six real Claude Code CLI sessions, and nothing counts as done until it is verified.
The split
Three workstreams, six terminals.
Extract
Sessions sweep hardcoded strings out of components and into keyed message files, each one working its own slice of the codebase so edits never collide.
Wire
Locale plumbing lands alongside extraction: the message loader, a language switcher, date and number formatting, and plural rules for every target language.
Translate
Each session takes one surface, such as settings, onboarding, or billing, and translates it in context instead of handing a spreadsheet of orphaned strings around.
One brief
Describe the goal, not the steps.
Type the goal once. The Conductor plans it into a mission DAG, orders extraction ahead of translation so dependencies hold, dispatches tasks across the fleet, and answers permission prompts so six sessions never sit waiting on you. Live activity strips show which surface each terminal is on, and the watchdog nudges any session that drifts.
# one goal, planned into a mission
$ Internationalize the app for de, fr, ja, and pt-BR.
Extract user-facing strings to locale files, add a
language switcher, then translate every surface.
Keep keys stable and keep the tests green.Questions
Common questions.
Will six sessions trip over the same files?
The mission DAG sequences the work so extraction lands before translation, and each session owns its own slice. Every pane is a real Claude Code TUI, so you can watch any terminal and type directly into one to redirect it.
What happens when a session hits a usage limit?
Loom parks the limited account and rotates to the next pooled Claude account, then retries. Stalled or exited sessions are relaunched and their tasks re-sent after recovery. Long passes like this also make good overnight runs.
How do I review the result?
The built-in source control panel shows a full git graph and diffs of everything the fleet shipped, and the auto-detected web preview lets you click through each locale before you push. See verification for how work is re-checked before it counts as done.
