fix(branding): replace remaining user-facing "Roo" strings with "Zoo" by proyectoauraorg · Pull Request #343 · Zoo-Code-Org/Zoo-Code

proyectoauraorg · 2026-05-27T09:19:59Z

What & why

Several user-visible strings still showed the upstream "Roo" brand instead of "Zoo". The most visible one was the missing-tool-parameter retry notice in chat:

Roo tried to use read_file without value for required parameter 'path'. Retrying...

That message was hardcoded in Task.ts (unlike its siblings unknownToolError / invalidJsonArgument, which are already localized to "Zoo"). The editor tab and several other surfaces had the same leftover.

Changes

Task.ts — the missing-parameter notice is now localized via new keys tools:missingToolParameter / tools:missingToolParameterWithPath, added and translated across all 18 locales (mirroring the existing unknownToolError pattern).
Titles — the editor tab title (createWebviewPanel), the webview <title>, the diff editor label (DIFF_VIEW_LABEL_CHANGES), and the integrated terminal name.
Commands/output — the "Cannot find any visible … instances" output-channel line.
Notifications — the credit-balance message and the LM Studio context-length error.
Router/cloud — the removal/sign-in messages in common.json (18 locales) and the fallback constants in routerRemoval.ts.

Tests updated to assert the new strings.

Intentionally not changed

To avoid breaking internals or rewriting history, these "Roo" occurrences are left as-is:

the legacy provider id roo and .roo* config file references;
i18n key paths (e.g. errors.roo.*);
OpenRouter X-Title attribution headers and MCP/checkpoint client names (sent to external services, not shown in the VS Code UI);
the deliberate fork-history announcement that references the original "Roo Code" project;
console/debug logs.

Note: the router/cloud group names a feature inherited-and-removed from upstream; if maintainers prefer to keep "Roo Code Router/Cloud" wording there, that group can be dropped without affecting the rest.

Verification

node scripts/find-missing-translations.js → ✅ all locales complete
tsc --noEmit on the changed files → clean
eslint → clean
vitest on the affected specs → 131 passing

Summary by CodeRabbit

New Features
- Added localized retry/error messages for missing tool parameters across 18 locales.
Documentation
- Updated user-facing branding from "Roo" to "Zoo" (Zoo Code, Zoo Code Cloud, Zoo Code Router) across UI copy and translations.
Tests
- Updated and added tests to reflect the new branding and missing-parameter message texts.

Several user-visible strings still showed the upstream "Roo" brand instead of "Zoo": - the missing-tool-parameter retry notice (was hardcoded in Task.ts; now localized via tools:missingToolParameter / missingToolParameterWithPath across all 18 locales, matching the existing unknownToolError pattern) - the editor tab title and the webview <title> - the diff editor label and the integrated terminal name - the "no visible instances" output-channel line - the credit-balance and LM Studio context-length error notices - the router/cloud removal messages (common.json + routerRemoval.ts) Internal identifiers are intentionally left unchanged: the legacy provider id "roo", .roo* config file references, i18n key paths, OpenRouter X-Title attribution headers, MCP/checkpoint client names, and console logs.

📝 Walkthrough

Walkthrough

Replaces user-facing "Roo" branding with "Zoo" across UI strings, webview titles, diff/terminal labels, router removal messages, LM provider messages, and adds localized missing-parameter messages across locales; tests updated to match.

Changes

Branding rename: Roo to Zoo

Layer / File(s)	Summary
I18n contract and Task implementation `src/i18n/locales/en/tools.json`, `src/core/task/Task.ts`	Adds `missingToolParameter` + `missingToolParameterWithPath` in English and updates `Task.sayAndCreateMissingParamError` to use i18n lookups with placeholders for `toolName`, `paramName`, and `relPath`.
Locale translations (18 languages) `src/i18n/locales//common.json`, `src/i18n/locales//tools.json`, `.changeset/*`	Adds the new `tools.json` keys for missing-parameter retry messages and replaces Roo→Zoo branding text in each locale's `common.json` entries (authenticationRequired, routerRemoved, signInUnavailable). Includes the changeset metadata.
Application UI and provider messages `src/activate/registerCommands.ts`, `src/core/webview/ClineProvider.ts`, `src/integrations/editor/DiffViewProvider.ts`, `src/integrations/terminal/Terminal.ts`, `src/core/webview/webviewMessageHandler.ts`, `src/core/config/routerRemoval.ts`, `src/api/providers/lm-studio.ts`, `src/api/providers/vscode-lm.ts`	Updates webview HMR/production titles, diff editor label, default terminal name, webview error payloads, router removal messages, LM Studio thrown error texts, and VS Code LM justification text to reference "Zoo" instead of "Roo".
Tests aligned to branding `src/activate/__tests__/`, `src/core/webview/__tests__/`, `src/core/config/__tests__/*`, `src/integrations/terminal/__tests__/TerminalRegistry.spec.ts`, `src/core/task/__tests__/Task.spec.ts`	Test expectations and mocks updated to expect "Zoo" branding; new tests added to validate Task missing-parameter messaging and i18n usage.

Poem

🐰 I hopped through strings from Roo to Zoo,
Titles and tests now wear brand‑new hue,
Locales whisper "Zoo" in every tongue,
A tiny rabbit hums — the work is done,
Cheers, little paws, a change well sprung!

Warning

There were issues while running some tools. Please review the errors and either fix the tool's configuration or disable the tool if it's a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

ESLint skipped: missing config or dependency (missing-dependency). The ESLint configuration references a package that is not available in the sandbox.

nice thanks for tackling there some feedback regarding legit Roo instances that should stay.

+			expect(saySpy).toHaveBeenNthCalledWith(1, "error", expect.any(String))
+			expect(saySpy).toHaveBeenNthCalledWith(2, "error", expect.any(String))


Could these also check that the resolved string actually contains the tool name or param name? If t() returns the key (or falls back to an empty string) in the test env, expect.any(String) still passes — so a silent i18n regression would go undetected here.

 const ROUTER_REMOVAL_I18N_KEY = "common:errors.roo.routerRemoved"
 const ROUTER_REMOVAL_DEFAULT_MESSAGE =
-	"Roo Code Router has been removed. Please select and configure a different provider."
+	"Zoo Code Router has been removed. Please select and configure a different provider."


this should stay as Roo - this whole file is referencing the old Roo router, but this should probably be i18n keyed, not sure why we'd need a default message.

+						toolName,
+						relPath: relPath.toPosix(),
+						paramName,
+					})
+				: t("tools:missingToolParameter", { toolName, paramName }),


nice - what does this render as?

edelauna · 2026-05-28T01:44:59Z

 				type: "rooCreditBalance",
 				requestId,
-				values: { error: "Roo credit balance is no longer available." },
+				values: { error: "Zoo credit balance is no longer available." },


leave this as Roo - wonder if this should be i18n keyed though

edelauna · 2026-05-28T01:45:25Z

router Removed should stay roo

same with this - this is an error message when trying to access roo as a provider

proyectoauraorg · 2026-05-28T04:12:16Z

Good catch @rrewll! That's a leftover string in vscode-lm.ts:398 — the justification message still says "Roo Code". I'll add it to the PR.

Let me push a fix now.
