# Next Steps: Testing & Tool Integration

**Created:** 2026-02-12

## ✅ What We Just Completed

### Type Unification (Major Fix!)
- ✅ Unified message format: `role` + `content` everywhere
- ✅ Database schema updated to match CoreMessage
- ✅ All storage providers updated
- ✅ Chat history now loads correctly
- ✅ UI displays messages properly

### Chat History & UI
- ✅ Chat history dropdown with search
- ✅ Tab persistence across restarts
- ✅ Active tab restoration
- ✅ Thinking card (auto-collapse, random phrases)
- ✅ Exploring card for tool calls

### Tools Integration
- ✅ Bash tool integrated with AI SDK
- ✅ Filesystem tools ready
- ✅ Tools registered in AgentService
- ✅ Tools passed to streamText
- ✅ 5 tools available: bash, read_file, write_file, list_directory, search_files

## 🎯 Immediate Next Steps

### Step 1: Test Tools in UI (30 minutes)

**Action:** Start the app and test bash tool

```bash
npm start
```

**Test Cases:**
1. Ask: "What files are in the current directory?"
2. Ask: "Run: git status"
3. Ask: "Show me package.json"
4. Ask: "Create a test file called hello.txt with 'Hello World'"

**Expected Behavior:**
- AI should use bash tool for commands
- File operations should use filesystem tools
- Tool calls should appear in "Exploring" card
- Tool results should be visible in response

---

### Step 2: Update Test Suite (2-3 hours)

**Files to Update:**

#### Priority 1: Core Tests (Update for role/content)
- `tests/storage-manager.test.ts` - Update message format
- `tests/local-storage.test.ts` - Update message format
- `tests/chat-session-manager.test.ts` - Update message format
- `tests/llm-streaming.test.ts` - Update message format

#### Priority 2: Integration Tests
- `test/integration/gateway-storage.test.ts` - Update if exists
- `test/integration/agent-streaming.test.ts` - Update if exists
- `test/integration/websocket-communication.test.ts` - Update if exists

#### Priority 3: UI Tests
- `ui/__tests__/**/*.test.ts` - Verify UI component tests

**Test Update Pattern:**
```typescript
// OLD (wrong)
const message: StoredMessage = {
  message: "test",
  message_role: "user",
  // ...
};

// NEW (correct)
const message: StoredMessage = {
  role: "user",
  content: "test",
  // ...
};
```

### Step 3: Tool Testing & Documentation (1 day)

#### 3a. Create Tool Test Suite
```bash
# File: tests/tools-integration.test.ts
```

**Test each tool:**
- Bash: execution, timeout, errors
- Read file: valid paths, missing files
- Write file: create, overwrite, permissions
- List directory: valid dirs, nested dirs
- Search files: glob patterns, content search

#### 3b. Document Tool Usage
Create `docs/TOOLS.md` with:
- Tool descriptions
- Usage examples
- Best practices
- Error handling
- Security considerations

### Step 4: Missing Features from V1 (Priority Order)

#### 4a. Jobs System (High Priority)
**Status:** Not started  
**Complexity:** Medium  
**Impact:** High (unique Paprwork feature)

**Architecture:**
```
~/papr-jobs/{id}/
├── job.json          # Job config
├── code/             # Python/Node/Swift code
├── venv/             # Python virtual env
├── data.db           # SQLite database
└── logs/             # Execution logs
```

**Tasks:**
1. Design job schema
2. Implement JobsManager in gateway
3. Create UI for job management
4. Add schedule execution
5. Implement job dependencies

#### 4b. Sub-Agents (Medium Priority)
**Status:** Not started  
**Complexity:** Low (uses existing agent)  
**Impact:** Medium

**Types:**
- Research agent (web search, document analysis)
- Code review agent (PR reviews, code quality)
- Writing agent (docs, emails, content)

**Implementation:**
- Use same AgentService with different system prompts
- Run in gateway process
- Communicate results to main chat

#### 4c. Mini-Apps (Medium Priority)
**Status:** Not started  
**Complexity:** Medium  
**Impact:** Medium (unique feature)

**Architecture:**
- TypeScript apps with React UI
- Query job SQLite databases
- Run in separate process
- Display in app window or browser

## 📋 Checklist for Today

- [ ] 1. Test bash tool in UI (ask questions that need commands)
- [ ] 2. Verify tool calls appear in "Exploring" card
- [ ] 3. Audit test files (list what needs updating)
- [ ] 4. Update 3-5 core tests with new message format
- [ ] 5. Run test suite to see current pass rate
- [ ] 6. Document tool usage patterns

---

## 🚀 Current Velocity

**Actual progress:** ~4 weeks into plan  
**Features completed:** Week 1-3 done, Week 4 partial  
**On track for:** Feature parity in 2-3 more weeks

**Blockers:** None - just need to:
1. Test what we built
2. Update test suite
3. Implement remaining V1 features

---

## 💡 Recommendations

### Immediate (Today):
1. **Test tools in UI** - Verify bash/filesystem tools work
2. **Update 5 key tests** - Get test suite green
3. **Document current state** - Update CLAUDE.md with learnings

### This Week:
1. **Complete test suite** - All tests passing
2. **Jobs system design** - Architecture document
3. **Sub-agents** - Simple implementation

### Next Week:
1. **Jobs implementation** - Full system
2. **Mini-apps framework** - Basic setup
3. **Migration tool** - Import V1 data

## 🎯 Success Criteria

**Before moving to jobs:**
- [ ] All tools working in UI
- [ ] Test suite passing (>80%)
- [ ] No TypeScript errors
- [ ] No console errors in UI
- [ ] Chat history fully functional
- [ ] Streaming works with reasoning

**You're 70% done with V2! 🎉**

The foundation is rock solid. Now it's about testing what we built and adding the unique Paprwork features (Jobs, Mini-apps).
