Problem

Provider instances using the same driver share its logo, making accounts and upstream vendors difficult to distinguish in the model picker and thread list. Local ACP commands likewise show the generic ACP icon, even when they represent different agents. This addresses only per-instance icons from discussion #7366, point 1.

Change

Add an optional HTTPS image URL to each provider instance, configurable when adding or editing the instance in Settings → Providers. Store it with the environment's settings and apply it to provider snapshots for all drivers, including local ACP commands. Web, desktop, and mobile render the image and fall back to the existing provider icon if it cannot load; Reset removes the override.

Carry the same icon through model selection, the sidebar, command-palette results, subagents, and usage-account displays. Distinct icons avoid unnecessary initials badges while retaining configured accent markers. Existing ACP registry icons remain the default when no override is set. This does not add drivers, file uploads, or a bundled brand catalog.

Scope and approval

Submitted under CONTRIBUTING.md's focused configuration option route: provider instances already support display names and accent colors, and clients already render driver-supplied icons. This option lets an instance override that visual identity without changing provider execution, model routing, authentication, or default icons. The contract, registry, client, tests, and user-guide changes all support that one option.

The linked discussion establishes the use cases; it contains no explicit maintainer approval, and is not presented as approval.

Verification

Focused tests cover icon URL validation, settings persistence and removal, independent instance icons, snapshot reads/refreshes/streams/workspace snapshots, unavailable drivers, local ACP branding, mobile catalog and saved-model entries, and badge disambiguation.
vp run check:changed passed formatting, lint, both unused-code checks, generated GraphQL checks, typechecks for 32 affected packages, and all 321 tests across 20 test files. This includes the five browser test files that were initially blocked; the missing Chromium executable has now been installed. No native device verification has been performed.
Browser verification used T3 Code's Browser panel with isolated demo state on Linux: baseline 0637f876fc65 versus feature commit 070c3c8873. Assigned icons through Settings to Kimi, OpenRouter, and two local ACP instances (Hermes and OMP); confirmed successful image loading, persistence in environment settings, and survival after a full page reload. A deliberately missing OMP image fell back to the generic ACP icon; Reset cleared the setting and restored that icon. Both local ACP instances kept source: local and their original executables/arguments. Providers stayed disabled and no agent turns were run.
The running installation has not been replaced or restarted.

Before / after

Before: Kimi uses Claude's logo, OpenRouter uses OpenCode's logo, and both local ACP commands share the ACP mark. After: each configured instance renders its selected image, and the selected Hermes instance exposes the icon setting and Reset control.

Before (upstream base)	After (this branch)
Provider instances using driver icons	Provider instances with individual icons

Full-resolution evidence is uploaded to GitHub, outside the source tree.

Implemented with GPT-6 Astra through the Codex harness in T3 Code.

Walkthrough

Provider instances now accept optional HTTPS icon URLs. The URLs are saved with instance configuration, included in provider snapshots and client data, and displayed in web and mobile interfaces with fallback icons.

Changes: Provider instance icons

Layer / File(s)	Summary
Icon contract and server snapshots `packages/contracts/src/providerInstance.ts`, `apps/server/src/provider/unavailableProviderSnapshot.ts`, `apps/server/src/provider/ProviderInstanceRegistry.ts`, `apps/server/src/serverSettings.test.ts`, `apps/server/src/provider/ProviderInstanceRegistry.test.ts`, `packages/contracts/src/providerInstance.test.ts`, `packages/contracts/src/server.ts`	The provider configuration accepts optional icon URLs validated for HTTPS, credentials, and length. Server snapshots include configured icons for available and unavailable instances. Tests cover snapshot propagation, reconciliation, and persistence.
Icon settings and provider branding `apps/web/src/components/settings/ProviderIconUrlInput.tsx`, `apps/web/src/components/settings/AddProviderInstanceDialog.logic.ts`, `apps/web/src/components/settings/AddProviderInstanceDialog.tsx`, `apps/web/src/components/settings/ProviderInstanceCard.tsx`, `apps/web/src/providerInstances.ts`, `apps/web/src/components/settings/AcpRegistrySearchStep.tsx`, `packages/provider-acp-registry/src/server/AcpRegistrySupport.ts`, `apps/web/src/providerInstances.test.ts`, `packages/provider-acp-registry/src/server/AcpRegistrySupport.test.ts`, `docs/user/install.md`	Provider settings add and edit an instance icon URL. Derived provider entries use explicit instance icons and resolve official registry icons for ACP Registry providers. Registry search results resolve official icon URLs.
Icon URLs in client data `apps/mobile/src/features/threads/thread-provider-instance.ts`, `apps/mobile/src/lib/modelOptions.ts`, `apps/mobile/src/lib/modelOptions.test.ts`, `packages/client-runtime/src/state/providerInstanceDisplay.ts`, `packages/client-runtime/src/state/providerInstanceDisplay.test.ts`, `packages/contracts/src/providerUsageLimits.ts`, `packages/shared/src/usageLimits.ts`	Model options and badge metadata receive provider icon URLs. Usage-limit account data preserves icon URLs when accounts are created and merged.
Provider stream subscriptions `apps/server/src/provider/ProviderRegistry.ts`, `apps/server/src/provider/ProviderRegistry.test.ts`	Live subscriptions retain their provider instance and fiber. The registry interrupts subscriptions for removed or replaced instances. Tests check streamed updates and subscription cleanup.
Icon rendering across provider interfaces `apps/web/src/components/chat/ProviderInstanceIcon.tsx`, `apps/mobile/src/components/ProviderIcon.tsx`, `apps/web/src/components/CommandPaletteThreadItems.tsx`, `apps/web/src/components/ThreadCommandSubtitle.tsx`, `apps/web/src/components/chat/*`, `apps/web/src/components/Sidebar.tsx`, `apps/web/src/components/sidebar/SidebarThreadRow.tsx`, `apps/web/src/components/onboarding/WelcomeWizard.tsx`, `apps/web/src/components/usage/UsageLimitsPooled.tsx`	Web and mobile provider icon components accept normalized icon URLs, show defaults while images load or after errors, and exclude official ACP Registry URLs from the custom-image path. Provider interface call sites now pass `iconUrl`.

Full details: Title check

Explanation

The title "feat(providers): allow per-instance icons" matches the main change. The PR adds an optional HTTPS icon URL to each provider instance, applies it across snapshots and displays, and supports Reset. It uses a conventional commit format and is specific enough for a teammate to understand the primary change.

Full details: Description check

Explanation

The description follows the template sections (Problem, Change, Scope and approval, Verification). The Problem section explains the shared driver logo issue and links the source discussion. The Change section describes the new per-instance icon option and where it applies. The Scope and approval section cites the focused configuration route and states that the linked discussion is not presented as maintainer approval. The Verification section lists focused tests, a check run, Linux browser verification with before/after evidence, and what was not verified (native devices). The template's opening HTML comment and the closing model-and-harness line are satisfied by the final line naming the model and harness. Coverage is thorough and specific, so the check passes.

Associate the validation message with the input.

When a URL is invalid, the input sets aria-invalid, but the error text has no input association or live announcement. A screen-reader user does not receive the reason for rejection when correcting the URL. Give the message an ID and connect it with aria-describedby; announce it when validation changes.

Pass the configured icon to both secret-related unavailable snapshots.
When secret loading is deferred or a secret cannot be read, these branches omit entry.iconUrl. The resulting unavailable snapshot loses the instance icon, even though the other unavailable branches preserve it. Add iconUrl: entry.iconUrl to both buildUnavailableProviderSnapshot calls. (raw.githubusercontent.com)

Keep instances distinguishable when custom images fail.

If two same-driver instances have different icon URLs and both images fail, ProviderInstanceIcon shows the same default icon for each. This comparison also removes their instance badges. Retain the sibling badge unless a successfully loaded icon distinguishes the instances; the simplest fallback is to count same-driver siblings regardless of URL. (raw.githubusercontent.com)

Keep registry icons on the trusted CDN path.

This branch treats any non-CDN registry icon as a user-configured override. AcpRegistrySearchStep passes registry metadata into this prop, and the server accepts and forwards any HTTPS icon URL. Opening registry search can therefore send requests to catalog-specified hosts and expose the user’s IP address without an override. Preserve the CDN allowlist for registry metadata and distinguish it from explicit overrides. (raw.githubusercontent.com)

Please review the latest head (8e186ede8fcf64512a9d1fa5cafc2dd1222f1fe0) again, including the registry icon CDN restrictions, sibling badge fallback, and icon preservation during secret loading failures. All 7 required checks have passed.

Written by gpt-6.1-sol on behalf of Maria

Verified in a real dev environment

Verified head 8e186ede8fcf64512a9d1fa5cafc2dd1222f1fe0 on Linux with repository Playwright and /usr/bin/google-chrome, against a background vp run dev server. No source changes were needed.

First ran github/main (8760d063e9) in a separate worktree: the Codex instance had its default logo and no icon setting. Created a project pointing at the real checkout through the app, then completed a real Codex gpt-6.1-sol turn.
Stopped main before starting the PR. Used the same app-created project and thread data. Set a custom icon through Settings, reloaded, and restarted the server: the saved icon remained visible in settings, the model picker, composer, and sidebar.
Added a second Codex instance through the app with a different icon. Switched instances through the model picker and completed real gpt-6.1-sol turns on both instances on the latest head.
Checked HTTP and credential-bearing URL rejection, missing-image fallback, Reset, and reset persistence after reload. Changing the second instance did not change the first instance's icon.
Ran five existing contract, client-display, web-provider, server-settings, and provider-registry test files through blacksmith-check: 127 tests passed.

Native iOS/Android and Electron clients were not exercised on this Linux browser pass. Non-Codex provider execution, local ACP commands, registry installation, subagent icon displays, usage-account displays, and remote/relay/tunnel connections were not exercised end to end. The VM's authenticated Codex proxy was used for real provider execution. This is a runtime verification result, not a claim that every PR check is green; the review-bot check was still pending when inspected.

Do not replace an active adapter for an icon-only update.
An icon-only update replaces the provider entry and closes the old adapter scope. The active prompt runs in sessionScope, but it uses the runtime backed by runtimeScope. Closing that scope can make runtime.prompt fail, and the prompt handler finalizes the current turn as failed or interrupted.
Update the live icon metadata without replacing the adapter or its runtime.

@coderabbitai please review the lifecycle fix in 055a39d81a. Icon-only changes now preserve the original adapter and scope, replace only the snapshot icon wrapper, and publish a registry change. Reset restores the original driver snapshot. The regression test failed before the fix and now verifies no scope closes across update, reset, and restore. All check:changed checks pass, including 432 tests across 25 files and 35 package typechecks.

Stop the superseded live-source subscription when an icon change replaces its instance.

An icon-only update builds a new decorated instance with withInstanceIcon and leaves the source scope open. syncLiveSources tracks instances by reference, so the new instance is not carried over and forks its own Stream.runForEach with Effect.forkScoped. The previous fiber is removed from liveSubsRef but never interrupted, so it keeps consuming the same source stream. Each repeated icon edit adds another running subscription. Each source publish can also reach syncProvider from the old fiber with the previous iconUrl, which can race with the current value.

Track the forked fiber for each instance id, and interrupt the previous fiber before forking the replacement when the instance reference changes.

@coderabbitai please review the subscription cleanup fix in 7593233877. ProviderRegistry now tracks each subscription fiber and interrupts it before replacing or removing its source. The regression test failed with two active subscriptions before the fix; repeated replacements now retain one subscription and removal leaves zero. All check:changed checks pass, including 481 tests across 26 files and 35 package typechecks.

CcoderabbitaiBot11d ago

@nozamdavid I’ll review the subscription cleanup fix in 7593233877. I’ll focus on interruption before source replacement or removal, plus the regression test for one active subscription after replacements and zero after removal.

I’ll use your reported check:changed results as context: 481 passing tests across 26 files and 35 package typechecks.

@coderabbitai review

Please review current head 7593233877d013b48af3b9123db94f21f68c0159. Automatic reviews paused during the recent fixes, and the earlier review was cancelled because the head changed. The subscription cleanup fix is now pushed and ready for review.

CcoderabbitaiBot11d ago

@nozamdavid I’ll review the lifecycle fix in 055a39d81a. I’ll check that icon-only changes preserve the original adapter and scope, replace only the snapshot icon wrapper, and publish a registry change. I’ll also check that Reset restores the driver snapshot and that the regression test covers update, reset, and restore without closing the scope.

I’ll use your reported results as context: 432 passing tests across 25 files and 35 package typechecks.

Written by gpt-6.1-sol on behalf of Maria
Verified in a real dev environment
Verified head 8e186ede8fcf64512a9d1fa5cafc2dd1222f1fe0 on Linux with repository Playwright and /usr/bin/google-chrome, against a background vp run dev server. No source changes were needed.
First ran github/main (8760d063e9) in a separate worktree: the Codex instance had its default logo and no icon setting. Created a project pointing at the real checkout through the app, then completed a real Codex gpt-6.1-sol turn.
Stopped main before starting the PR. Used the same app-created project and thread data. Set a custom icon through Settings, reloaded, and restarted the server: the saved icon remained visible in settings, the model picker, composer, and sidebar.
Added a second Codex instance through the app with a different icon. Switched instances through the model picker and completed real gpt-6.1-sol turns on both instances on the latest head.
Checked HTTP and credential-bearing URL rejection, missing-image fallback, Reset, and reset persistence after reload. Changing the second instance did not change the first instance's icon.
Ran five existing contract, client-display, web-provider, server-settings, and provider-registry test files through blacksmith-check: 127 tests passed.
Runtime transcript:
1 main: serverPort=16733 webPort=8693
2 Codex / gpt-6.1-sol -> provider icon verification ok.
3 PR: serverPort=13773 webPort=5733
4 Codex Second / gpt-6.1-sol -> latest head codex second ok.
5 Codex / gpt-6.1-sol -> latest head codex original ok.
Before, same Codex instance on main:
main provider settings without an icon override
After, original instance plus a separately configured second instance:
PR settings with independent Codex instance icons
URL validation, image fallback, reset, and restoring the second icon URL validation, image fallback, reset, and restoring the second icon
real Codex turns completed on both instances on the latest head

Hhan6696699d ago

This comment gives the case that this PR unblocks. Issue #19192 was closed as a duplicate of the local ACP part of #7366.

Case. A local ACP command starts a vendor CLI. The agent is not in the ACP Registry. The instance connects, lists models, and runs turns. But every surface shows the generic ACP glyph. If you configure two such bridges, the picker and the thread rows show the same icon. Only the two-letter badge tells them apart. Built-in logos do not cover private bridges. A per-instance image URL gives each instance its own mark.

Diff at 0562713. These parts work for this case:

iconUrl is optional on the instance config. The schema accepts https only. It rejects credentials and limits the length.
entryEqual ignores iconUrl. The iconsChanged path rebuilds from sourceInstance with withInstanceIcon. So an icon edit does not restart the provider runtime. That is the failure mode I expected.
Web keeps the old icon when the image fails to load. Mobile shows the custom image without a tint. A colored mark stays colored.
Registry agents keep the validated CDN path. An instance without an icon looks the same as today. The change only adds behavior.

One optional note. The custom icon renders as a plain <img>. It does not use the image/*, 512 KB, and redirect: "error" checks that registry icons use. A URL that the user typed is a different trust case. One sentence in the PR body will answer the question before a reviewer asks it.

I can test a build on a local ACP instance and report the result.

Written by my agent, manually posted here by me. Best, Han
