feat(mobile): support configurable Quick Chat backends by iscekic · Pull Request #7322 · Kilo-Org/cloud

iscekic · 2026-10-09T00:22:19Z

Changelog for users

Configure Quick Chat backends with Chat Completions, Responses, or Messages. Kilo remains the default.
Add models manually, discover models when supported, and test a real inference request before saving.
Choose modern max_completion_tokens or legacy max_tokens for Chat Completions endpoints.
Keep each conversation's backend separate, including concurrent chats and queued questions.
Confirm context transfer before changing backends. Text-only models receive no tools.
Edited or deleted backends require a new explicit selection. Failed questions retain their original target through Retry and restoration.
Sign-out and account changes remove backend profiles and credentials.
HTTPS remains the default. Local HTTP needs endpoint-specific approval; Android release builds remain HTTPS-only.

Changelog for maintainers

Add the focused @kilocode/harness-sdk/plugins/remote-model entry. The SDK continues to own history, compaction, and tools.
Share SSE parsing with Kilo while retaining direct-provider authentication and wire differences.
Preserve interleaved tool identities, direct assistant reasoning, and cancellation of pending stream reads.
Route each request through an immutable backend ID, revision, and upstream model ID.
Keep custom authentication separate from Kilo authentication. Block Kilo headers, redirects, and ambient cookies.
Clear backend credentials durably before publishing another account's credentials.
Persist failed question text and target together. Migrate old text records explicitly and remove records when conversations are deleted.
Add translated backend settings in all 87 catalogs. Keep the generated store changelog unchanged.

Verification

Built and installed the Android debug app on the owned GCE emulator with isolated backend services and two approved fake accounts.
Exercised discovery, real connection checks, streaming chat, all three protocols, and identical upstream IDs on distinct backends.
Confirmed explicit handover preserves the ORBIT conversation context. Cancel retained the draft and original backend.
Confirmed edit/delete recovery, explicit deleted-target errors, draft retention, profile persistence after relaunch, and account cleanup.
Held one inference request while another backend completed its own chat. Released the first request and observed its correct response.
Exercised modern and legacy token fields through the native settings and connection check. Observed checked radio states and saved selection.
Ran a disposable SDK consumer on the VM with real HTTP inference, local tool execution, reasoning replay, and tool-result replay.
SDK: 70 focused tests, typechecks, lint, build, all 11 built entry points, and platform/dependency checks passed.
Mobile: 166 focused tests, three auth lifecycle tests, typecheck, lint, unused-code check, and all 87 catalog checks passed.
Provider fixtures use synthetic credentials. No production model calls or real account changes.
Native iOS behavior is not exercised in this PR. The iOS configuration adds only the local networking exception.

Stack

Base: feat(mobile): agent-callable settings tools and remote MCP server management (part 1/1) #6706, above feat(mobile): rebuild the chat tab on the harness SDK #5895 and feat(harness-sdk): the kilo harness SDK #5878.
This PR implements configurable remote backends. The remaining planned PRs add Apple Foundation Models, Android Gemini Nano, and llama.rn/GGUF support.

Android native evidence: explicit context-transfer approval, independently routed chat, and accessible completion-token field selection. These screens use isolated fake accounts and synthetic provider credentials.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental change guards the pre-send target check on stored-backend load state, letting the registry validate a not-yet-loaded custom target instead of falsely reporting it deleted; the registry path (registry.ts:107) awaits waitForChatBackends and re-resolves via resolveChatTarget at stream time, and the test-only backend-store mocks match the real clearChatBackends wiring.

Previous review (commit `b69cb54`)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental commit b69cb54 only extends the case-guard allowlist with three backend files whose bare toLowerCase() calls normalize HTTP header names and compare hostnames, so no display text is re-cased; all three sites are verified non-display and the guard stays sound.

Previous review (commit `a510d83`)

Status: No Issues Found | Recommendation: Merge

Executive Summary

The incremental commit a510d83 makes Retry re-enter the chat before retrying, so a chat whose open failed now does recover; enterChat is a no-op for an already-open chat, and the previously reported inert-Retry suggestion is resolved.

Status: 1 Issue Found | Recommendation: Address before merge

Executive Summary

All seven findings from the previous review are resolved by 5ef970d50b; the one new issue is a failure row whose Retry is inert when a chat fails to open rather than when a tool change fails.

Previous review (commit `e4a6c42`)

Status: 7 Issues Found | Recommendation: Address before merge

Executive Summary

Backend target staleness and credential retention dominate the remaining findings: a queued question can be silently dropped when its custom backend is deleted, sign-out does not durably delete backend credentials, and the chat list can start on a stale backend.

main landed the Quick Chat stack as squash merges (#7322-#7342), so the branch's stack history conflicted on 141 files. Resolve by keeping main's integrated content for the stack files, and reapplying this branch's own change on top: - turns.ts keeps main's image support and question shapes, drops the model input, and exports askedMessageId. - turns.test.ts drops the model input and uses Question[] waiting. Verified: turns.test.ts (11) and chat-screen.mounted.test.tsx (14) pass.

main landed the Quick Chat stack as squash merges (#7322-#7342). Resolve the 141-file conflict by keeping main's integrated content and reapplying this branch's mode-chip change on top: - chat-toolbar.tsx keeps main's per-chip disabled dimming and gains the optional modeControl (modeSelector is null without it). - chat-composer.tsx takes modeControl and keeps main's image picker import. - chat-composer.test.ts drops the mode props (no leftover imports). - session-detail-content.test.ts reads customOptions through modeControl. Verified: chat-composer, chat-composer-attachment-send, chat-toolbar, session-detail-content, new-session-configure-form, chat-toolbar-model-name, chat-composer-send-once, chat-screen mounted, and oxlint on the changed files.
