What changed

  • Replaced provider-owned static model arrays with a catalog() contract that discovers the current model list and defaults from each CLI or provider.
  • Carries model-specific effort, service tier, tool-use, and provider metadata through bot persistence, validation, individual turns, group turns, and cloud execution.
  • Uses native discovery surfaces, including Codex app-server model/list + config/read, ACP initialization, Kimi provider JSON, Droid CLI help + Factory settings, Claude CLI help + settings, and provider APIs.
  • Keeps the last UI catalog visible, refreshes it in the background every five minutes, and adds a small manual refresh control with an inline spinner.

Why

The picker previously exposed a small hardcoded subset of models. Its Refresh action only rechecked CLI availability, so newly released models and account/config-specific defaults never appeared. Static capability assumptions also allowed unsupported effort or service-tier combinations to reach a driver.

This change makes the installed CLI/provider the source of truth while keeping the picker responsive from cached state.

How it was verified

  • Node 24: pnpm typecheck
  • Node 24: pnpm test -- --reporter=dot — 52 files, 436 passed, 8 skipped; updater suite 11 passed
  • Node 24: pnpm check:electron
  • Node 24: pnpm build
  • Focused provider, registry, selection validation, group-turn, and picker-state tests
  • Real Droid CLI 0.197.0 smoke: discovered 43 models and the native GPT-5.6 Sol effort/default metadata
  • Packaged macOS app smoke: opened the picker, refreshed the catalog, selected effort/service tier, and confirmed only one Fast option is shown
  • GitHub Actions on the identical head SHA: macOS, Windows, Ubuntu, and Ubuntu package/lifecycle smoke all passed

Checklist

  • pnpm typecheck and pnpm test pass locally
  • Server behavior changes come with tests (see CONTRIBUTING.md → Tests)
  • No dist-server/ edits (it's build output)
  • macOS-only code is platform-gated; no shell: true / cmd.exe string-building
  • No secrets in logs, responses, events, or argv

Summary by CodeRabbit

  • New Features
    • Model catalogs now update dynamically with available models, defaults, reasoning effort, processing tiers, and tool support.
    • Added manual catalog refresh with loading and error feedback; catalogs also refresh automatically.
    • Model selection validates availability and supported settings before saving or starting a turn.
    • Tool compatibility is checked for computer and agent tasks.
  • Bug Fixes
    • Improved handling of unavailable models, provider errors, invalid selections, and outdated defaults.
    • The model picker remains open when additional configuration is available and displays clearer instance and catalog statuses.

📝 Walkthrough

Walkthrough

The PR replaces static model lists with dynamic provider catalogs. It adds structured selections with effort and service-tier metadata, validates selections server-side, forwards provider details to adapters, and updates the model picker with refresh and capability controls.

Changes

Dynamic model catalogs and selection

Layer / File(s) Summary
Selection contracts and server validation
server/contracts.ts, server/models.ts, server/index.ts, server/harness/registry.ts
Catalogs now return structured model metadata. Server paths validate model, provider, effort, service tier, cloud compatibility, and tool support before dispatch or persistence.
Provider catalog discovery and forwarding
server/drivers/antigravity.ts, server/drivers/boxagent.ts, server/drivers/claude.ts, server/drivers/codex.ts, server/drivers/grok.ts, server/drivers/acp/*
Providers discover models dynamically from CLIs, APIs, settings, and ACP or app-server protocols. Selected model, effort, service-tier, and provider values are forwarded to provider requests.
Client catalog state and picker controls
src/state/store.tsx, src/components/ModelPicker.tsx, src/components/NoEngines.tsx
The client stores structured catalogs, refreshes them periodically or manually, and displays model errors, effort controls, service tiers, and tool capabilities.
Fixtures and validation coverage
server/testing/*, server/*test.ts, scripts/e2e-server.mjs, README.md
Fake providers and tests cover catalog discovery, selection validation, provider forwarding, communication flows, refresh failures, and updated model-picker behavior. README text documents the catalog flow.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to bf2df

The PR dynamically discovers provider model catalogs and propagates model capabilities, but the current head still contains a localized declaration that violates a repository correctness rule. Merge should wait for that fix or explicit owner acceptance; no broader product risk is indicated.

203-203: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Avoid a CLI round trip on every turn that omits a model.

configureSession runs on the turn path. When turn.model is empty, this line spawns droid exec --help and waits up to 20 seconds before the prompt is sent. A transient CLI failure now fails the turn, where the previous static default did not. Consider caching the catalog per instance with a short TTL, or reading only sessionDefaultSettings.model for this fallback.

Inline comments:
In `@README.md`:
- Around line 64-66: Update the model picker description to state that catalogs
may come from installed CLIs or supported provider APIs, while preserving the
existing details about defaults, effort levels, processing tiers, caching,
refresh behavior, and validation.

In `@server/drivers/acp/core.ts`:
- Line 645: Update the applySelection invocation in the turn handling flow to
use the same timeout-applying request wrapper as configureSession, with
SESSION_CONFIG_TIMEOUT as the default. Ensure the wrapped request is passed to
support.applySelection so its underlying session/set_model and
session/set_config_option calls cannot remain pending indefinitely.

In `@server/drivers/claude.ts`:
- Around line 160-163: In server/drivers/claude.ts lines 160-163, update the
CLI-default option created in the configuredModel fallback so the empty model id
does not include provider metadata or otherwise pass cloud compatibility checks;
preserve provider metadata for concrete models. In server/drivers/claude.test.ts
lines 125-132, update the CLI-default expectation to assert that the empty
option has no cloud provider metadata.

In `@server/drivers/codex.ts`:
- Around line 66-71: Set UTF-8 encoding on both stdout and stderr before
attaching data handlers in readCatalog at server/drivers/codex.ts:66-71 and in
the catalog probe at server/drivers/acp/core.ts:213-214, preventing multibyte
characters split across chunks from being corrupted.
- Around line 159-174: Update the default model selection and lookup in the
catalog-building flow so hidden models cannot become the default: resolve the
listed default only if its id exists in options, otherwise fall back to
options[0].id. Ensure option is always obtained from the same validated options
list before accessing defaultEffort or defaultServiceTier, and remove the unsafe
non-null assumption in the option lookup.

In `@server/index.test.ts`:
- Around line 298-307: Extend the rejected PATCH cases in the bot update test to
fetch the bot after each request and assert that modelSelection remains
unchanged from its original value. Add these persistence assertions for both the
malformed and unavailable requests while retaining the existing response checks.

In `@server/testing/fake-codex-app-server.ts`:
- Line 110: Update the fake server’s model/list handling to follow nextCursor
across all pages, aggregating models until the cursor is null before selecting
the default model. Adjust the fake model/list response to expose two pages with
a non-null cursor on the first and null on the second.

In `@src/components/ModelPicker.tsx`:
- Around line 206-207: Update the ModelPicker selection value to distinguish
absent serviceTier from explicit null: use option.defaultServiceTier when
selection.serviceTier is undefined, while retaining the empty-string Standard
representation for explicit null. Keep the existing onChange behavior in
updateOption unchanged.

모델 선택 요청에 기본 timeout을 적용하고 Droid가 로컬 기본 모델을 사용할 때 불필요한 CLI 실행을 피했습니다. Catalog probe의 UTF-8 스트림 처리도 함께 보완했습니다.

빈 모델 ID가 Claude CLI 내부 기본값을 뜻하는 경우 provider metadata를 제거해 클라우드 실행 대상으로 오인되지 않도록 했습니다.
model/list의 모든 cursor 페이지를 합치고 숨김 모델이 기본값으로 보고되어도 첫 표시 모델을 사용하도록 했습니다. Catalog JSON 스트림에는 UTF-8 decoding을 명시했습니다.

Constraint: Codex model/list는 cursor 기반으로 여러 페이지를 반환할 수 있음

저장값이 없을 때는 모델 기본 처리 등급을 표시하고 명시적인 null은 Standard로 유지하도록 했습니다.
잘못된 모델 선택 요청이 실패 응답만 반환하고 기존 bot 선택값은 보존하는지 각 거부 경로에서 확인했습니다.
모델 목록이 설치된 CLI뿐 아니라 지원되는 provider API에서도 올 수 있음을 현재 동작에 맞춰 설명했습니다.
