- Introduced a new setting to enable automatic loading of CLAUDE.md files from project-specific directories.
- Updated relevant services and components to support the new setting, including the AgentService and AutoModeService.
- Added UI controls for managing the auto-load setting in the settings view.
- Enhanced SDK options to incorporate settingSources for CLAUDE.md loading.
- Updated global and project settings interfaces to include autoLoadClaudeMd property.
- Added support for resuming conversations using the Claude SDK session ID.
- Updated the ClaudeProvider to conditionally resume sessions based on the presence of a session ID and conversation history.
- Enhanced the AgentService to capture and store the SDK session ID from incoming messages, ensuring continuity in conversations.
- Enhanced the executeQuery method to better handle conversation history and user messages, ensuring compliance with SDK requirements.
- Introduced a default tools array for allowedTools, simplifying the options setup.
- Updated the getAvailableModels method to use type assertions for model tiers and ensured proper return type with TypeScript's satisfies operator.
- Added error handling during query execution to log and propagate errors effectively.
- Updated model resolution logic to only check for gpt-* models, removing references to unsupported o1/o3 models in both model-resolver and provider-factory files.
- Enhanced comments for clarity regarding model support in Codex CLI.
Created 5 new utility modules in apps/server/src/lib/ to eliminate ~320 lines of duplicated code:
- image-handler.ts: Centralized image processing (MIME types, base64, content blocks)
- prompt-builder.ts: Standardized prompt building with image attachments
- model-resolver.ts: Model alias resolution and provider routing
- conversation-utils.ts: Conversation history processing for providers
- error-handler.ts: Error classification and user-friendly messages
Updated services and providers to use shared utilities:
- agent-service.ts: -51 lines (removed duplicate image handling, model logic)
- auto-mode-service.ts: -75 lines (removed MODEL_MAP, duplicate utilities)
- claude-provider.ts: -10 lines (uses conversation-utils)
- codex-provider.ts: -5 lines (uses conversation-utils)
Added comprehensive documentation:
- docs/server/utilities.md: Complete reference for all 9 lib utilities
- docs/server/providers.md: Provider architecture guide with examples
Benefits:
- Single source of truth for critical business logic
- Improved maintainability and testability
- Consistent behavior across services and providers
- Better documentation for future development

Implements a flexible provider pattern that supports both Claude Agent SDK
and OpenAI Codex CLI, enabling future expansion to other AI providers
(Cursor, OpenCode, etc.) with minimal changes.
## Architecture Changes
### New Provider System
- Created provider abstraction layer with BaseProvider interface
- Model-based routing: model prefix determines provider
- `gpt-*`, `o*` → CodexProvider (subprocess CLI)
- `claude-*`, `opus/sonnet/haiku` → ClaudeProvider (SDK)
- Providers implement common ExecuteOptions interface
### New Files Created
- `providers/types.ts` - Shared interfaces (ExecuteOptions, ProviderMessage, etc.)
- `providers/base-provider.ts` - Abstract base class
- `providers/claude-provider.ts` - Claude Agent SDK wrapper
- `providers/codex-provider.ts` - Codex CLI subprocess executor
- `providers/codex-cli-detector.ts` - Installation & auth detection
- `providers/codex-config-manager.ts` - TOML config management
- `providers/provider-factory.ts` - Model-based provider routing
- `lib/subprocess-manager.ts` - Reusable subprocess utilities
## Features Implemented
### Codex CLI Integration
- Spawns Codex CLI as subprocess with JSONL output
- Converts Codex events to Claude SDK-compatible format
- Supports both `codex login` and OPENAI_API_KEY auth methods
- Handles: reasoning, messages, commands, todos, file changes
- Extracts text from content blocks for non-vision CLI
### Conversation History
- Added conversationHistory support to ExecuteOptions
- ClaudeProvider: yields previous messages to SDK
- CodexProvider: prepends history as text context
- Follow-up prompts maintain full conversation context
### Image Upload Support
- Images embedded as base64 for vision models
- Image paths appended to prompt text for Read tool access
- Auto-mode: copies images to feature folder
- Follow-up: combines original + new images
- Updates feature.json with image metadata
### Session Model Persistence
- Added `model` field to Session and SessionMetadata
- Sessions remember model preference across interactions
- API endpoints accept model parameter
- Auto-mode respects feature's model setting
## Modified Files
### Services
- `agent-service.ts`:
- Added conversation history building
- Uses ProviderFactory instead of direct SDK calls
- Appends image paths to prompts
- Added model parameter and persistence
- `auto-mode-service.ts`:
- Removed OpenAI model block restriction
- Uses ProviderFactory for all models
- Added image support in buildFeaturePrompt
- Follow-up: loads context, copies images, updates feature.json
- Returns to waiting_approval after follow-up
### Routes
- `agent.ts`: Added model parameter to /send endpoint
- `sessions.ts`: Added model field to create/update
- `models.ts`: Added Codex models (gpt-5.2, gpt-5.1-codex*)
### Configuration
- `.env.example`: Added OPENAI_API_KEY and CODEX_CLI_PATH
- `.gitignore`: Added provider-specific ignores
## Bug Fixes
- Fixed image path resolution (relative → absolute)
- Fixed Codex empty prompt when images attached
- Fixed follow-up status management (in_progress → waiting_approval)
- Fixed follow-up images not appearing in prompt text
- Removed OpenAI model restrictions in auto-mode
## Testing Notes
- Codex CLI authentication verified with both methods
- Image uploads work for both Claude (vision) and Codex (Read tool)
- Follow-up prompts maintain full context
- Conversation history persists across turns
- Model switching works per-session
