From 701ab18d818c37bbaf68f7a0ac0e5e2f8c9c7f34 Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 12 Apr 2026 22:14:45 +0000 Subject: [PATCH] fix(models): block unconfigured models from selection surfaces MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Filter models whose provider has no working API key or OAuth out of every user-facing selection path. Previously, stale defaults and scoped sets could leak unconfigured models into /model, /gsd model, and auto run — the user could "pick" a model that immediately threw on use. - model-selector: filter scopedModels via isProviderRequestReady; default to "all" scope when no scoped model is ready. - model-controller: same filter for getModelCandidates, so exact-match resolution from /model can't return an unauth'd scoped model. - model-resolver: gate findInitialModel step 3 on provider readiness so a stale saved default falls through to the available-models path. - startup-model-validation: check configuredExists against getAvailable instead of getAll, so a configured-but-unauth default triggers the fallback picker and thinking-level reset. - auto-start: validate resolveDefaultSessionModel against the live registry + auth before snapshotting, and warn when PREFERENCES.md names an unconfigured model. https://claude.ai/code/session_015q6b23ap9Pyqdogzz2FXGh --- .../src/core/model-resolver.test.ts | 85 +++++++++++++++++++ .../interactive/components/model-selector.ts | 21 +++-- .../controllers/model-controller.ts | 7 +- src/resources/extensions/gsd/auto-start.ts | 32 ++++++- .../tests/auto-start-model-capture.test.ts | 14 +++ src/startup-model-validation.ts | 9 +- src/tests/startup-model-validation.test.ts | 27 ++++++ 7 files changed, 181 insertions(+), 14 deletions(-) create mode 100644 packages/pi-coding-agent/src/core/model-resolver.test.ts diff --git a/packages/pi-coding-agent/src/core/model-resolver.test.ts b/packages/pi-coding-agent/src/core/model-resolver.test.ts new file mode 100644 index 000000000..d15e93793 --- /dev/null +++ b/packages/pi-coding-agent/src/core/model-resolver.test.ts @@ -0,0 +1,85 @@ +/** + * Regression test for the #unconfigured-models fix: findInitialModel() must + * skip the saved default when its provider has no working auth, rather than + * returning an unusable model that every selector surface would display as + * "current". + */ + +import test from "node:test"; +import assert from "node:assert/strict"; +import { findInitialModel } from "./model-resolver.js"; + +function fakeRegistry(options: { + models: Array<{ provider: string; id: string }>; + readyProviders: Set; +}) { + const fullModels = options.models.map((m) => ({ + ...m, + name: m.id, + api: "anthropic-messages", + baseUrl: "", + reasoning: false, + input: ["text"], + cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 }, + contextWindow: 128_000, + maxTokens: 4096, + })); + const available = fullModels.filter((m) => options.readyProviders.has(m.provider)); + return { + find(provider: string, id: string) { + return fullModels.find((m) => m.provider === provider && m.id === id); + }, + getAvailable() { + return available; + }, + isProviderRequestReady(provider: string) { + return options.readyProviders.has(provider); + }, + }; +} + +test("findInitialModel skips saved default when provider has no auth", async () => { + // User saved xai/grok-4 as default, but XAI_API_KEY is unset so xai is + // in the registry but not ready.
