Summary

Two related bugs prevent using non-Claude providers for spec generation:

1. /create endpoint ignores settingsService - User's configured specGenerationModel is ignored, always defaults to Claude opus
2. Structured output assumed for non-Cursor models - Code only checks isCursorModel() but doesn't account for OpenCode, Codex, or other providers

Steps to Reproduce

1. Go to Settings > Model Defaults
2. Set "Spec Generation Model" to a non-Claude model (e.g., opencode/glm-4.7-free)
3. Go to Spec Editor and create a new spec
4. Bug 1: Error: "Claude CLI is disconnected from the app" (even though Claude isn't configured)
5. After fixing Bug 1 manually, Bug 2: Error: "Failed to generate spec: No valid XML structure found in response"

Root Cause

Bug 1: Missing settingsService in /create endpoint

File: apps/server/src/routes/app-spec/routes/create.ts

// Line 19 - missing settingsService parameter
export function createCreateHandler(events: EventEmitter) {

File: apps/server/src/routes/app-spec/index.ts

// Line 20 - settingsService not passed
router.post('/create', createCreateHandler(events));

Bug 2: Incorrect structured output detection

File: apps/server/src/routes/app-spec/generate-spec.ts

// Line 111 - only checks for Cursor, not other non-Claude providers
const useStructuredOutput = !isCursorModel(model);

Should be:

const useStructuredOutput = isClaudeModel(model);

Suggested Fix

Bug 1:

- export function createCreateHandler(events: EventEmitter) {
+ export function createCreateHandler(events: EventEmitter, settingsService?: SettingsService) {

And pass settingsService to generateSpec() call and in index.ts.

Bug 2:

- import { DEFAULT_PHASE_MODELS, isCursorModel } from '@automaker/types';
+ import { DEFAULT_PHASE_MODELS, isClaudeModel } from '@automaker/types';

- const useStructuredOutput = !isCursorModel(model);
+ const useStructuredOutput = isClaudeModel(model);

Environment

• Automaker version: 0.11.0
• Node version: v24.12.0
• OS: Linux

Impact

Users cannot use non-Claude providers (OpenCode, Codex, etc.) for spec generation, even when explicitly configured in settings.
