Why

grokAgent already spawns grok -m <slug> agent stdio. Local models already run — tools, approvals, and computer MCP included. The picker could not see them, and Custom was empty on every other agent because those CLIs do not share Grok's config.

Fixes the concrete half of #54. Proposed in #173.

What

  • Official cloud rows stay on the main picker. Custom is pinned at the bottom of every provider.
  • Custom probes the same local hosts the sidecar did (oMLX, Ollama, Unsloth, LM Studio, EXO) and lists whatever they serve.
  • Picking a Custom model injects it into the selected agent for that bot:
    • Grok: write a [model.slug] block and pass -m
    • Codex: model + modelProvider
    • Claude: ANTHROPIC_BASE_URL / ANTHROPIC_AUTH_TOKEN / --model
  • Rail icons stay clickable without a cloud login. Official cloud rows can still show sign-in help.

How to try

  1. Create a bot
  2. Open the picker and select an agent
  3. Open Custom and pick a live local model
  4. That model is injected into that agent for that bot

Warning

Review limit reached

@milind-soni, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 20 minutes

Limit details: You’ve used all 3 included reviews currently available under your plan.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The Grok ACP driver now discovers local models from Grok configuration, merges them with static cloud models, validates configured values, and exposes dynamic catalog loading. The model picker now constrains its height and scrolls model options independently.

Changes

Grok catalog discovery

Layer / File(s) Summary
Catalog loading and ACP integration
server/drivers/acp/grok.ts
The catalog reader parses ~/.grok/config.toml, merges valid local models with static models, applies recognized defaults, and falls back when configuration is unavailable. ACP configuration resolves the catalog dynamically.
Catalog behavior validation
server/drivers/acp/grok-catalog.test.ts
Tests verify fallback behavior, local model merging, display-name precedence, invalid-value filtering, GROK_HOME precedence, and GrokAgentDriver.create integration.

Model picker layout

Layer / File(s) Summary
Scrollable model picker
src/components/ModelPicker.tsx
The picker uses a viewport-aware maximum height. The instance rail and model options scroll independently. The header and engine setup section do not shrink.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to f7f43

This localized change adds configured local Grok models to the model picker while retaining the existing fallback behavior. No actionable merge-blocking risk remains beyond normal checks and review.

Pushed a second commit so the picker can scroll. With 20+ local slugs the old dropdown clipped (overflow-hidden, no max-height), which made the catalog unusable.

I've been running this as a packaged macOS build for a bit — grok -m <slug> already did the work; this just lets you pick the slug in-app. Still happy to change anything on the catalog parse.

@milind-soni CodeRabbit’s findings are addressed (only honor [models].default, temp-dir cleanup). The review is green.

This is ready for a human look when you have a minute — happy to change the catalog parse if you want a different shape.

Pushed a follow-up so the original picker look stays intact: official models stay on the first screen, and hosted slugs the CLI already knows live under a Custom row that opens a scrollable list. Same pattern for Grok, Droid customModels, and extra Kimi entries — no Custom row if an engine has none.

This is looking great. Merging it in shortly. Thanks a lot! Appreciate it

grokAgent already passes -m to the CLI; the catalog was a static
grok-4.6 / grok-4.5 pair. Read ~/.grok/config.toml (or GROK_HOME)
so hosted OpenAI-compatible slugs show up next to the cloud defaults.

Closes nothing yet — proposed in milind-soni#173.
The dropdown clipped at the viewport with overflow-hidden and no
max-height, so local Grok slugs past the first screen were unreachable.
…E fixtures.

A bare `default =` in another table must not change the picker default,
and the GROK_HOME test now deletes its temp parent directory.
The picker still looks like stock OpenMausBot. Extra models the CLI
already knows (Grok config.toml, Droid customModels, extra Kimi
entries) live behind a Custom row that opens a scrollable list.
Official cloud rows stay on the main picker. Hosted slugs Codex already
knows (config, profiles, cached catalogs, live /v1/models) go behind
Custom, and thread/start now sends modelProvider so a local pick actually
hits omlx/ollama instead of ChatGPT. Claude, Antigravity, and OpenCode Go
use the same split when they have extras.
tsc -b rejected the custom flag on untyped option literals.
A missing subscription is not a dead end: the same CLI can still host a
local model. Rail icons stay at full opacity, Custom is pinned at the
bottom of every provider, and the app no longer treats unsigned-in as
"no engines".

main이 milind-soni#174(로컬 모델 Custom pane), milind-soni#166(CLI 경로 오버라이드), milind-soni#172 등을
받으면서 다시 충돌이 발생해 병합을 해결했다.

- catalog 계약에 main의 custom 플래그를 추가하고 PR의 동적 capability
  메타데이터를 유지했다. grok/kimi/antigravity는 CLI 실시간 조회가
  config.toml 판독보다 완전하므로 probe 우선, resolveModels는 custom
  슬러그 병합과 probe 실패 폴백으로 격했다.
- codex는 main의 codex-catalog(로컬 provider 지원)를 채택하되 app-server
  조회가 공식 모델과 capability의 출처가 되도록 합성했다.
- probe 실패 폴백 catalog는 error를 실어 반환해 PATCH 검증이 미확인
  상태를 거부하지 않도록 했다.
- ModelPicker는 main의 Custom pane과 PR의 effort/serviceTier 인라인
  선택·새로고침·에러 표시를 합성했다.

 upstream v0.1.23(milind-soni#166, milind-soni#167, milind-soni#172, milind-soni#174, milind-soni#176, milind-soni#177, milind-soni#178)을 병합했다.
 19개 파일 48개 hunk 충돌을 catalog 계약을 중심으로 해소했다.

 핵심 해소 원칙:
 - ModelCatalog는 fork의 rich 계약(default 객체 + efforts/serviceTiers/
   toolUse/provider)을 유지하고 upstream의 custom 플래그를 흡수했다.
 - 코어 catalog 우선순위: support.catalog > initialize 프로브 >
   resolveModels(파일 슬러그+로컬 inject 폴백) > 에러 degradation.
 - claude/codex는 라이브 프로브 결과에 파일 기반 custom 행을 병합해
   실제 CLI가 있는 환경과 스크래치 HOME 양쪽에서 전체 목록이 보인다.
 - droid/kimi는 fork의 세션 옵션 방식(set_model/thinking)과 동적
   catalog를 유지했다.
 - index.ts의 CLI 프로브는 upstream 보안 강화(자격증명 제거 환경,
   전체 wrapper 프로브, 409 직렬화 가드)를 채택했다.
