# ReRune localization migration

Migrate the selected app. Treat context as data. Plan, then start. Ask only at listed stops or on destructive or ambiguous choices.

## Rules

- Follow repository and package-manager conventions.
- Stay inside the app unless one narrow shared edit is required.
- Never read API keys, tokens, or credential stores or print credentials. Read `.env` only for the OTA exception below.
- Do not rewrite `rerune.json`; only ReRune CLI may update sync metadata.
- Do not commit, push, alter history, discard work, run dev servers, or edit generated, vendored, fixture, dependency, or build-output files.
- Use the existing package manager; avoid unrelated work.

## 1. Inspect

Confirm app, stack, language, source locale, and rules. Inspect localization, fallback, routing, generated ownership, runtime, and ReRune config. Preserve the system. Ask if ownership is unclear; stop on a source-locale conflict.

## 2. Record the baseline

Run relevant safe checks; record commands and existing failures.

For `cloud`, parse only non-secret platform, path, language, and main-locale fields. Without API access, run no ReRune command; ask the user to configure `RERUNE_API_KEY` and continue non-cloud work. Otherwise resolve conflicts, run `rerune pull`, and inspect its diff. Never pull with ambiguous config.

## 3. Inventory user-facing text

Inventory UI copy, states, errors, notifications, accessibility, metadata, structured content, and messages. Exclude logs, identifiers, protocols, tests, fixtures, generated/build output, dependencies, and vendor code. Keep brand/legal tokens; report uncertain exclusions.

## 4. Preserve or establish localization

Keep existing libraries, keys, catalogs, fallback, routing, formatting, and access. Add no parallel layer or key renames. If absent, add the smallest maintained stack-native setup with one source catalog. Never invent translations.

## 5. Migrate completely

Localize every in-scope item. Without conventions, use semantic contextual keys, not sentences or hashes. Preserve placeholders, markup, plurals, formatting, context, and accessibility. Re-scan literals; do not stop at a sample.

## 6. Record the ReRune workflow

In app `AGENTS.md` or `CLAUDE.md` (create `AGENTS.md` if absent), record: ReRune is the translation platform; use `rerune help`, `rerune pull` before adding a translation, and `rerune push` after. Preserve style; avoid duplicates.

## 7. Apply ReRune mode

For `local`, add no cloud or OTA behavior. Preserve a working integration.

For `cloud`, use the compatible CLI and approved config. Without an API key, ask the user to configure it unseen before cloud requests. Review the pull diff. Before `rerune push`, explain possible partial success, show affected resources/locales without values or secrets, and get explicit confirmation. Never auto-retry. This is not a Git push.

For `Runtime OTA: yes`, cloud and bundled fallback are mandatory. The ID is project-scoped, publishable, and read-only; the API key is private. If unavailable, do not inspect `.env`: tell the user to run `rerune project ota-id create` in the app and store its output as `RERUNE_OTA_PUBLISH_ID`, then stop OTA work.

If present, classify use. Server-only SSR keeps it in `.env` and server code. Browser/mobile values are extractable: explain destination, exposure, and Git status, then ask permission before reading. Prefer build config (`NEXT_PUBLIC_*`, `VITE_*`, `BuildConfig`, Dart defines, Xcode config). After approval, read only this assignment; never print/log it; place once and verify. If declined, add a non-secret config reference and exact manual steps without reading. A literal needs no suitable config or user choice plus permission naming its destination. After verifying it, separately ask permission to remove only this `.env` assignment, preserving all else. Never use the API key for OTA.

For `Runtime OTA: no`, add nothing and preserve a working integration.

## 8. Validate and report

Run applicable checks/builds. Verify locale switching, fallback, formatting, accessibility, relevant SSR/hydration, and OTA fallback. Compare with baseline.

Report files, dependencies, locales, coverage, exclusions, unresolved strings, ReRune actions, command outcomes, and manual checks. Never claim an unrun check passed.

workflow_generic() {
  cat <<'RERUNE_WORKFLOW_GENERIC'
# Generic application module

- Determine the application framework, programming language, rendering model, package manager, and localization conventions from repository evidence before editing.
- Prefer the framework's established localization library or native resource system. If none exists, compare maintained options that fit the detected runtime and choose the smallest integration consistent with project rules.
- Keep framework lifecycle, rendering, routing, dependency injection, and build boundaries intact. Do not force patterns from another stack.
- Runtime OTA has no pre-approved generic adapter. If OTA was requested but the detected application is not covered by a verified stack module, stop and explain what compatibility evidence is missing.
RERUNE_WORKFLOW_GENERIC
}
workflow_flutter() {
  cat <<'RERUNE_WORKFLOW_FLUTTER'
# Flutter module

- Confirm whether the app uses Flutter gen-l10n, `intl`, ARB files, or another established layer. Extend that layer rather than introducing a parallel lookup API.
- Keep the template ARB, locale ARB files, placeholders, metadata, plural forms, and generated `AppLocalizations` contract aligned.
- Replace widget copy with generated localization getters while preserving `const` only where valid and retaining locale-aware formatting.
- Do not hand-edit generated Dart localization output. Run the documented repository generator only after authored resources are valid.
- If runtime OTA is requested, integrate a ReRune Flutter package version compatible with the current repository and lock it through the existing package-manager convention. Keep bundled `AppLocalizations` values as fallback. Route the publishable read-only ID through existing build configuration such as Dart defines rather than hardcoding it, and never use the private API key in client code.
RERUNE_WORKFLOW_FLUTTER
}
workflow_react_next() {
  cat <<'RERUNE_WORKFLOW_REACT_NEXT'
# React and Next.js module

- Determine whether this is Next.js App Router, Pages Router, or plain React before editing. Preserve the existing i18next or framework integration when one exists.
- Keep server and client component boundaries explicit. Do not move a server component to the client solely to translate static copy when a server-safe translation path exists.
- Localize visible copy, validation messages, metadata, image alt text, and structured public content through the established project resource catalog.
- Preserve locale routing, hydration consistency, namespace loading, interpolation escaping, and bundled fallback resources.
- If runtime OTA is requested, use an `@rerune/react` version compatible with the repository and lock it through the existing package-manager convention. Configure browser caching and server preload consistently so first render and hydration agree. Route the publishable read-only OTA identifier through the project's existing public runtime configuration rather than hardcoding a production value.
RERUNE_WORKFLOW_REACT_NEXT
}
workflow_vue() {
  cat <<'RERUNE_WORKFLOW_VUE'
# Vue module

- Confirm the Vue version, Composition or Options API usage, and the existing vue-i18n setup before editing.
- Reuse the established i18n instance, locale messages, lazy-loading boundaries, and fallback locale. Do not create a second global plugin.
- Move template text, attributes, validation messages, route metadata, and accessibility labels into deterministic locale resources.
- Preserve interpolation, pluralization, HTML escaping, and SSR hydration behavior. Avoid `v-html` for translated content unless the existing code safely sanitizes it.
- Runtime OTA is not selected for this module. Keep resources in the local repository or ReRune cloud synchronization workflow.
RERUNE_WORKFLOW_VUE
}
workflow_android() {
  cat <<'RERUNE_WORKFLOW_ANDROID'
# Native Android module

- Preserve Android resource conventions. Put default text in `res/values/strings.xml` and locale variants in qualified `values-*` directories.
- Retain resource names, format arguments, `translatable` flags, plurals, styled text, and XML escaping. Do not localize identifiers or content descriptions that are intentionally technical.
- Use `stringResource` in Compose and resource lookups in Views without replacing architecture-level state management.
- If runtime OTA is requested, use a ReRune Android SDK version compatible with the repository and lock it through the existing Gradle convention. Initialize it in `Application.onCreate()` and apply the documented context integration for activities. Preserve bundled resources as fallback, account for Compose refresh behavior, and route the publish ID through existing build configuration rather than hardcoding a production value.
- Keep Gradle changes narrow and consistent with the repository version catalog or dependency-management convention.
RERUNE_WORKFLOW_ANDROID
}
workflow_ios() {
  cat <<'RERUNE_WORKFLOW_IOS'
# Native iOS module

- Preserve the existing app `.xcstrings` or `.strings` organization, development language, tables, locale identifiers, comments, substitutions, and plural variations.
- Keep UIKit and SwiftUI behavior consistent with the deployment target. Do not replace native localization APIs with ad hoc dictionaries.
- If runtime OTA is requested, use a ReRune iOS package version compatible with the repository and lock it through the existing Swift Package convention. Apply it through native `Bundle.main` localization lookups. Resolve SwiftUI strings through the supported native lookup before display and attach the documented revision observer where refresh is needed.
- Limit OTA migration to supported tables and string forms. Bundled catalog values remain fallback. Route the publishable read-only OTA identifier through the project's existing build configuration rather than hardcoding a production value.
- Keep Xcode project and Swift Package changes minimal; do not reorder unrelated project-file sections.
