The current src/i18n/index.ts/src/i18n/locale.ts changes introduce broken imports/exports and a localize() API mismatch that will fail compilation/runtime for existing call sites.

src/i18n/index.ts:15
index.tscurrently changes thelocalize()API and stops exportinggetOpenClaudeCommandDescriptionKey/ i18n types, but the rest of the codebase still imports these from./i18n/index.jsand callslocalize(key, fallback, values?). As-is, this will break compilation and consumers.
Consider restoring the previous exports and localize(key, fallback, values?) signature (you can keep zh-HK support and still add env-based locale detection in locale.ts).
export type Locale = keyof typeof dictionaries;
export function getDictionary(locale: string) {
return dictionaries[locale as Locale] ?? dictionaries.en;

Fix the dictionary type contract before registering zhHK.
I18nDictionary requires every LocalizationKey, but src/i18n/languages/zh-HK.ts contains only a subset of those keys. For example, it does not define commands.add-dir.description. This assignment therefore fails TypeScript checking and blocks the build.
Either complete the zh-HK dictionary or use a partial type that matches the existing English fallback.
Possible registry fix

[P2] Add regression coverage for the environment locale paths
src/i18n.locale.test.ts:13
The production change adds a second locale-selection path: when the saved language is absent or unsupported,detectLocale()now readsLC_ALL, thenLC_MESSAGES, thenLANG, normalizes the locale, and falls back to English. The only new test injectssettings.language = 'zh-HK', which returns before any of that new code runs; it would still pass if environment detection were removed, its precedence were reversed, or its fallback handling regressed.The root cause is that the test covers the pre-existing settings path rather than the behavior introduced by this PR. Please add isolated, preferably table-driven cases for precedence,
zh_HK.UTF-8normalization, non-target values such aszh_CNanden_HK, and unsupported or empty environment values falling back to English. Save and restore onlyLC_ALL,LC_MESSAGES, andLANGaround each case so the suite cannot leak process state. This is the current-head CodeRabbit request and can be addressed without changing settings persistence or UI behavior.

[P2] Use the canonical key for the onboarding translation
src/i18n/languages/zh-HK.ts:19
The production lookup starts incommandDescriptions.ts, where/onboard-githubis assignedcommands.onboard-github.description; the English and Vietnamese dictionaries use that same hyphenated key. This new dictionary instead definescommands.onboard_github.description. When the command is rendered underzh-HK,localize()indexes the dictionary with the canonical key, getsundefined, and silently selects the English fallback. A direct runtime lookup reproduces the English onboarding description even though this file contains a Chinese translation.The root cause is that the new dictionary data was validated with a different happy-path key (
commands.provider.description) rather than through the canonical key requested by the command. String-valued localization keys plus intentional per-key fallback make this class of typo invisible to compilation and smoke testing. Please rename this entry tocommands.onboard-github.descriptionand add a focused regression that selectszh-HKand resolves that canonical key (or renders the actual command description). Keep the fix scoped to this supplied translation: partial dictionaries and English fallback are supported, so this does not require translating every existing key, wiring unrelated UI strings, or redesigning the i18n types.

[P2] Preserve and isolate locale state in the new tests
src/i18n.locale.test.ts:44
The suite does not preserve the state it mutates. The settings-only case never callssnapshotEnv(), so its firstafterEachsees the initially emptysavedEnvand deletes the runner's originalLC_ALL,LC_MESSAGES, andLANG. Every environment case then callsclearLocaleEnv()beforesnapshotEnv(), which guarantees that the saved values areundefined; cleanup can never reconstruct the incoming environment. Because Bun shares process state across tests, later locale-sensitive tests can run under a different environment even though this file itself remains green.There is a second determinism problem in the same setup: after cleanup resets the session cache, the environment cases allow
detectLocale()to callgetInitialSettings(). A developer or CI worker with a supported persistedsettings.languagewill return through the settings branch before the intended environment branch is exercised. The root cause is that setup/teardown controls only selected examples rather than owning both inputs todetectLocale()for every case. Make the shared test lifecycle capture the three variables before any mutation, explicitly arrange an empty settings cache for environment-path cases, and restore/reset both sources afterward. Keep this correction inside the tests; production precedence and unrelated environment or settings state should remain unchanged. This is the current CodeRabbit isolation request and the present implementation does not satisfy it. -
[P2] Use the canonical onboarding localization key
src/i18n/languages/zh-HK.ts:19
/onboard-githubgets its localization key fromsrc/i18n/commandDescriptions.ts, where the canonical value iscommands.onboard-github.description. This new dictionary independently spells itcommands.onboard_github.description.localize()performs an exact dictionary lookup, so a zh-HK session misses the new entry and selects the existing English value; a runtime lookup at this head reproduces the English onboarding description.The root cause is duplicated, free-form string identity without a regression through the real consumer:
LocalizationKeycurrently accepts any string, and the PR's manual check used the unrelated working keycommands.provider.description, so neither TypeScript nor that check could catch this typo. Reuse the existing hyphenated key and add focused coverage that obtains or renders the actual/onboard-githubcommand description under a zh-HK session. Keep the fix scoped to this canonical-key mismatch—partial dictionaries and English fallback are supported, so this does not require redesigning the localization types, translating every command, or wiring unrelated UI.

[error] 24-30: Recursive/iterative merge copies attacker-controllable keys from a source object into a target via a computed property assignment without rejecting dangerous keys, allowing prototype pollution. Skip or block "proto", "constructor", and "prototype" keys (e.g. if (key === "__proto__" || key === "constructor" || key === "prototype") continue;), use a null-prototype object (Object.create(null)), or use a safe merge utility instead.
Context: for (const key of ['LC_ALL', 'LC_MESSAGES', 'LANG'] as const) {
if (ORIGINAL_ENV[key] === undefined) {
delete process.env[key]
} else {
process.env[key] = ORIGINAL_ENV[key]
}

I found one code issue that needs to be addressed before this is ready, plus two merge-readiness items. I have kept this review bounded to contracts established by this PR and the repository; the previously corrected items are not being reopened.
Merge readiness

[P2] Rebase the branch onto current
main
src/i18n/locale.ts:1
The PR head is still based onaceacf0e590a7d84447a8c44f3aa61eba781a542, while livemainis0ea8eefbd0d48735ddb9e6b8c9e7ee6957dc9b98. The branch is currently mergeable and the two intervening target commits do not overlap these i18n changes, so this is not evidence of a code conflict. It is here because the repository's explicit contribution policy requires follow-up branches to be rebased before their next push/merge. Please rebase first, then run the final validation batch against that exact result so the evidence applies to the branch that will actually merge. -
[P2] Encode the requested locale-variable precedence as an invariant
src/i18n.locale.test.ts:111
The current environment tests prove thatLC_ALL,LC_MESSAGES, andLANGare each recognized when they are the only populated source. They do not prove the requested orderLC_ALL > LC_MESSAGES > LANG: an implementation that checked those variables in reverse would still pass every case. Add at least one case in which all three variables contain different supported locales—for example,LC_ALL=en_US.UTF-8,LC_MESSAGES=zh_HK.UTF-8, andLANG=vi_VN.UTF-8, expecting English—and preferably table-drive the adjacent fallthrough cases where a higher-priority variable is empty. Keep the existing snapshot/restore isolation and empty settings cache so host state cannot decide the result. The production selector atsrc/i18n/locale.ts:17-21already has the intended order; this asks for the missing regression, not a rewrite.

/usage's plan-limit contract in the zh-HK description
src/i18n/languages/zh-HK.ts:23
The new text describes/usageas showing API usage and token consumption. The canonical command description isShow plan usage limits, and invoking it opens the Usage settings tab, whose provider-specific views show plan allowance and rate-limit windows. Session token/cost accounting lives in separate status/state surfaces. Because the command registry maps the actualusagecommand to this localization key and the formatter substitutes the translated value, zh-HK users are promised functionality this command does not provide. Change this entry to retain the existing plan/provider-limit meaning; do not expand/usageto implement token accounting. Then protect the contract with a consumer-driven test that starts from the actual/usagecommand metadata, obtains its canonical description key, and renders it through the production localization path. A test that hand-selects the dictionary key and supplies a hand-written fallback can confirm lookup mechanics while missing exactly this semantic divergence.
Root-cause guidance for this follow-up
The number of review rounds does not point to a need for another localization redesign. It comes from fixing individual reported examples while the tests still describe examples rather than the underlying contracts:
- The locale tests ask whether each environment source works alone, rather than whether conflicting sources obey their precedence invariant.
- The command-description tests ask whether a dictionary key can be translated, rather than whether the translated text remains faithful to the real command that consumes it.
- As a result, narrow fixes can all pass while a reordered selector or semantically incorrect command description remains undetected.
Please address these together as one bounded correction: rebase; fix the one /usage string; add the conflicting-variable precedence matrix; and add the real-consumer /usage regression. Before pushing, compare the other translated command descriptions that this PR actually makes reachable against their canonical command metadata, then run the repository's full required validation once over the complete rebased change. That adjacent comparison is meant to prevent another semantic finding from dripping out later; it is not a request to complete the dictionary or localize unrelated UI.
Scope boundary
No change is requested for platform/Intl locale fallback, zh-Hant-HK or other additional BCP-47 forms, GitHub Models versus Copilot naming, localization-key types, currently inert model/buddy/repomap entries, or broader UI wiring. Those either lack an accepted contract in this PR, predate it, or would expand its scope. The closure target is exactly one code correction, one missing contract test, the policy-required rebase, and a final validation run.
