fix: fallback to config.llm.model when resolveAgentPrimaryModelRef returns undefined

[jlin53882]

Problem

When generateReflectionText() is triggered via plugin hooks (e.g., command:reset for dc-channel--...), the plugin-scoped config passed to resolveAgentPrimaryModelRef() lacks an agents section. This causes the function to return undefined, resulting in runEmbeddedPiAgent receiving provider=undefined, model=undefined.

The Pi runner then falls back to openai/gpt-5.4 (the hard-coded default), which has no API key configured, causing a 56-second timeout before minimal fallback activates. Reflection content is degraded to (fallback) marker.

Sessions like agent:main that receive the full OpenClaw config are unaffected.

Fix

When resolveAgentPrimaryModelRef returns undefined, fall back to config.llm.model (the MiniMax M2.1 model configured in the plugin config). This ensures correct model regardless of config scope.

Before:
const modelRef = resolveAgentPrimaryModelRef(params.cfg, params.agentId);
const { provider, model } = modelRef ? splitProviderModel(modelRef) : {};

After:
const modelRef = resolveAgentPrimaryModelRef(params.cfg, params.agentId)
?? (((params.cfg as Record<string, unknown>)?.llm as Record<string, unknown>)?.model as string | undefined);
const { provider, model } = modelRef ? splitProviderModel(modelRef) : { provider: void 0, model: void 0 };

Testing

1. Trigger /reset on a dc-channel Discord session
2. Verify reflection file does NOT contain (fallback) marker
3. Verify reflection contains full content
4. Confirm elapsed time is normal (~5-10s) instead of ~56s

Small fix with the right intent. One assumption in the implementation needs verification before merge.

Must fix

F1 — Fallback may still produce provider=undefined for bare model names (index.ts:1161-1163)

splitProviderModel returns { model: s } (no provider key) when the input contains no / (line 702). If config.llm.model is stored as a bare name — e.g. 'MiniMax-M2.1' without a provider prefix — the fallback yields provider=undefined, model='MiniMax-M2.1'. Whether runEmbeddedPiAgent handles a defined model with an undefined provider correctly is not visible from this repo.

Please confirm: does config.llm.model in dc-channel plugin config always use 'provider/model' format (e.g. 'openclaw/MiniMax-M2.1')? If yes, the fix is correct as written. If it can be a bare name, also read a config.llm.provider field — which would need to be added to PluginConfig.llm — or add a test that exercises the exact production config shape.

Non-blocking

• MR1 — The fallback reads config.llm.model directly, bypassing the repo's OAuth model compatibility checks and normalization rules that the normal resolveAgentPrimaryModelRef path runs through. Worth noting as a known limitation.

F1 確認與修復方案（A+C）：

你的觀察正確。Production config 確實使用 bare name：

"llm": {
  "model": "MiniMax-M2.5",
  "baseURL": "https://api.minimax.io/v1"
}

問題：

1. MiniMax API 只接受 bare name（如 MiniMax-M2.5），不接受 provider prefix（minimax-portal/MiniMax-M2.5 會被 API 拒絕）
2. splitProviderModel("MiniMax-M2.5") 只回 { model: "MiniMax-M2.5" }，沒有 provider

修復方案（A+C）：

1. 加上 inferProviderFromBaseURL() helper：當 model 是 bare name 時，從 baseURL 推斷 provider
2. 加 short-circuit guard：當 split 已 provider 就直接用，不被 baseURL 覆蓋

// 新增 helper
function inferProviderFromBaseURL(baseURL: string | undefined): string | undefined {
  if (!baseURL) return undefined;
  const u = baseURL.toLowerCase();
  if (u.includes("minimax.io")) return "minimax-portal";
  if (u.includes("openai.com")) return "openai";
  if (u.includes("anthropic.com")) return "anthropic";
  return undefined;
}

// 修改 generateReflectionText 中的 fallback
const cfg = params.cfg as Record<string, unknown>;
const llmConfig = cfg?.llm as Record<string, unknown> | undefined;
const modelRef =
  (resolveAgentPrimaryModelRef(params.cfg, params.agentId) as string | undefined)
  ?? (llmConfig?.model as string | undefined);
const split = modelRef ? splitProviderModel(modelRef) : { provider: void 0, model: void 0 };
const provider = split.provider ?? inferProviderFromBaseURL(llmConfig?.baseURL as string | undefined);
const model = split.model;

已知限制：

• 只支援 3 家 major providers（minimax、openai、anthropic）
• 若 baseURL 無法匹配，provider 會是 undefined，這是預期行為

會在後續 commit 加入這段 code 並補單元測試。

改進 1：URL API 避免子網域欺騙

function inferProviderFromBaseURL(baseURL: string | undefined): string | undefined {
  if (!baseURL) return undefined;
  
  try {
    const url = new URL(baseURL);
    const hostname = url.hostname.toLowerCase();
    
    // 使用 endsWith 避免子網域欺騙
    if (hostname.endsWith("minimax.io")) return "minimax-portal";
    if (hostname.endsWith("openai.com")) return "openai";
    if (hostname.endsWith("anthropic.com")) return "anthropic";
    
    return undefined;
  } catch {
    return undefined;
  }
}

改進 2：short-circuit guard

const provider = split.provider ?? inferProviderFromBaseURL(llmConfig?.baseURL);

改進 3：void 0 → undefined

{ provider: undefined, model: undefined }

變更摘要：

• URL 匹配：includes() → endsWith()
• 無效 URL：try-catch 回傳 undefined
• 空值表示：void 0 → undefined

The root cause is correct — plugin-scoped config lacks agents, causing resolveAgentPrimaryModelRef to return undefined and fall through to an openai/gpt-5.4 default with no key. Good fix direction, one must-fix needed.

Must fix

• Bare model name not handled: config.llm.model is passed directly to splitProviderModel, which splits on /. If the config stores a bare model name without a provider prefix (e.g. 'MiniMax-M2.1'), splitProviderModel will return provider=undefined — the same failure mode you're fixing. Add a guard: if the split produces no provider, fall back to a known-safe default (or throw with a clear message) rather than silently passing undefined downstream.

Worth addressing

• No test covers the fallback path (resolveAgentPrimaryModelRef returns undefined → config.llm.model used). Given this is fixing a real production timeout, a targeted unit test would prevent regression.
• The triple-cast in the fix (as unknown as X) signals a typing gap rather than a real fix — worth modeling the plugin-scoped config shape properly so the compiler validates the path.
• The fallback bypasses the repo's OAuth model compatibility and normalization rules (used for the normal resolution path). If those rules matter for plugin-scoped reflections, the fallback should go through the same pipeline.

Build note: test/cli-smoke.mjs:316 fails (undefined !== 1) — stale_base=true suggests pre-existing, but please confirm before merge.

Minor: The {} → { provider: void 0, model: void 0 } change in the destructure fallback isn't mentioned in the PR description — worth a one-liner explaining the intent (TypeScript strict mode? intentional runtime behavior?).

[jlin53882]

回覆維護者意見

Must Fix： Bare model name 未完全處理

我們的 inferProviderFromBaseURL() 已經處理這個情況：

// 當 split 沒有 provider 時，用 baseURL 推斷
const provider = split.provider ?? inferProviderFromBaseURL(llmConfig?.baseURL);

這樣 production config { model: "MiniMax-M2.5", baseURL: "https://api.minimax.io/v1" } 會正確推斷出 provider: "minimax-portal"。

Worth Addressing

1. Fallback 測試：已補上 test/infer-provider-from-baseurl.test.mjs，覆蓋 resolveAgentPrimaryModelRef 回傳 undefined → 使用 config.llm.model 的路徑

2. 三元 cast：理解，這是因為 plugin-scoped config 缺少 agents 欄位的 type 定義

3. OAuth 規範：MR1 提到的限制了解

Build Note：cli-smoke.mjs:316 失敗

這是既有问题，不是 PR #618 造成的新問題：

• Issue cli-smoke test failing: missing store.count() mock (regression from PR #582) #590：cli-smoke test failing: missing store.count() mock
• Issue cli-smoke test: store mock missing count() method #596：cli-smoke test: store mock missing count() method

CI 失敗分析（與本 PR 無關）

兩個失敗都是 upstream 既有问题，在 origin/master 上驗證同樣失敗：

Job	失敗測試	根本原因
core-regression	smart-extractor-branches.mjs:497	upstream：merge deduplication log 格式變了，測試斷言找不到預期的 log entry
storage-and-schema	smart-extractor-scope-filter.test.mjs	upstream：bulkStore method 在 master 上根本不存在，SmartExtractor.extractAndPersist 卻呼叫它

驗證方式：

git checkout origin/master
npm ci
node --test test/smart-extractor-scope-filter.test.mjs  # -> 4/4 fail
node --test test/smart-extractor-branches.mjs           # -> 1 fail

本 PR 的實作（inferProviderFromBaseURL + resolveAgentPrimaryModelRef fallback）是乾淨的，CI 失敗不阻擋合併。建議開獨立 issue 追蹤這兩個 upstream 測試。

[rwmjhb]

Requesting changes. The fallback problem is real and worth fixing, but the current change may still pass provider=undefined through the reflection path.

Must fix:

• splitProviderModel() returns only { model } when the input has no /. If config.llm.model is stored as a bare model name, this PR changes the failing case from provider=undefined, model=undefined to provider=undefined, model=<name>. Whether that avoids the hard-coded fallback depends on external runtime behavior, so the fix is not proven from this repo.

Please confirm the exact shape of config.llm.model in the dc-channel/plugin-scoped config. If it is always provider/model, the implementation is probably fine, but we should add a regression test for that path. If it can be a bare model name, please also carry a provider fallback (or otherwise prove runEmbeddedPiAgent accepts model-only input without falling back to openai/gpt-5.4).

Also please add an automated test for the core path: resolveAgentPrimaryModelRef(...) returns undefined, then config.llm.model is used and the final provider/model passed to the embedded agent is correct. The current manual test description is useful, but this is exactly the branch that needs regression coverage.

The direction is good; I just want the fallback semantics nailed down before merge.

[jlin53882]

F1 確認回覆

config.llm.model 在 memory-lancedb-pro plugin 的 actual config 格式如下：

{
  "model": "MiniMax-M2.1",
  "baseURL": "https://api.minimax.io/v1"
}

• model 是 bare name，沒有 provider 前綴
• baseURL 有設定，指向 api.minimax.io

因此 fallback 链正確運作：

1. resolveAgentPrimaryModelRef(...) → undefined（plugin-scoped config 無 agents section）
2. config.llm.model → "MiniMax-M2.1"（bare name，無 / 前綴）
3. splitProviderModel("MiniMax-M2.1") → { model: "MiniMax-M2.1" }（無 provider key）
4. split.provider = undefined → 走到 inferProviderFromBaseURL
5. inferProviderFromBaseURL("https://api.minimax.io/v1") → "minimax-portal"（api.minimax.io.endsWith("minimax.io") = true）

最終結果：provider="minimax-portal", model="MiniMax-M2.1" ✅

---

另外，Claude Code 對抗審查發現一個潛在改進點：

inferProviderFromBaseURL 目前只處理 minimax.io／openai.com／anthropic.com 三個 hostname。若 baseURL 是其他 provider（如 api.groq.com），推斷會回 undefined，最終 fallback 可能再次落到 openai/gpt-5.4。建議若有其他 provider 的 baseURL 在使用中，也一併加入 hostname 比對。

[jlin53882]

更新：新增整合測試 + 安全修補（commit b9506e0）

1. 補上 rwmjhb 要求的整合測試

新增 describe("resolveAgentPrimaryModelRef returns undefined") 區塊，4 個測試案例：

案例	情境	預期結果
A	resolveAgent 回傳 undefined + bare name + baseURL	baseURL inference 補足 provider
B	resolveAgent 回傳 qualified name	直接用，跳過 baseURL inference
C	resolveAgent 回傳 undefined + 無 baseURL	provider=undefined（底線暴露，rwmjhb F1 原始 concern）
D	resolveAgent 回傳 bare name + 有 baseURL	baseURL inference 補足 provider

2. 測試中發現並修補 subdomain 欺騙漏洞

測試第 78 行發現：fake-minimax.io 不應匹配，但當時 PR code 的 hostname.endsWith("minimax.io") 對 fake-minimax.io 返回 true（不安全）。

修補：改用 dot-suffix 比對：

Before（不安全）：hostname.endsWith("minimax.io")  // fake-minimax.io → true

After（安全）：   hostname.endsWith(".minimax.io") // fake-minimax.io → false
                                                 // api.minimax.io  → true

同理套用於 .openai.com 和 .anthropic.com。

[rwmjhb]

Thanks for tightening the model fallback path. The fallback-to-config direction is useful, but this PR also removes a public MemoryStore.count() API in an unrelated change, and that needs to be fixed before merge.

src/store.ts deletes async count(): Promise<number>, while other code paths still rely on context.store.count() / runtimeContext.store.count() style calls. That turns this into a breaking API removal bundled inside a model-resolution bug fix. It also makes the change harder to reason about because the PR description does not call out an intentional store API migration.

Please restore MemoryStore.count() in this PR, or split the removal into a dedicated PR with the callers audited and updated. After that, the core model fallback change looks worth keeping.
