🔄 Handoff Procedures

For New Agents/LLMs

Step 1: Read This File

• Start here: This PROJECT_STATE.md file
• Then read: docs/plans/2024-06-22-hostkeeper-design.md (architecture)
• Then read: docs/plans/2024-06-22-hostkeeper-implementation.md (tasks)

Step 2: Check Current Status

# Check git status
git status

# Check recent commits
git log --oneline -5

# Check what files exist
find . -name "*.go" -type f

Step 3: Determine Next Action

1. Look at "Implementation Task Status" above
2. Find first incomplete task
3. Refer to implementation plan for detailed instructions
4. Execute following TDD approach

Step 4: Update This File

After completing any task, update the corresponding status section:

#### ✅ Task X: [Task Name]
- **Status**: Completed
- **Completion Date**: [Date]
- **Notes**: [Any important notes]
- **Commits**: [Relevant commit hashes]

For Returning Agents

Quick Status Check

# What's been done recently?
git log --oneline --since="2 weeks ago" | head -10

# What tests are passing?
make test 2>&1 | tail -20

# What's the current state?
go run cmd/hostkeeper/main.go --version

Resume Work

1. Check "Implementation Task Status" in this file
2. Find last completed task
3. Continue with next incomplete task
4. Update status as you progress

🧪 Testing Strategy

Test Categories

1. Unit Tests - Individual component testing
2. Integration Tests - Cross-component testing
3. E2E Tests - Full workflow testing

Running Tests

# All tests
make test

# With coverage
make test-coverage

# Specific package
go test ./pkg/storage -v

# Watch mode (if installed)
go test ./... -watch

Current Test Coverage

• Target: 80%+ coverage
• Current: 0% (no tests yet)
• Priority: Write tests first (TDD approach)

---

🚨 Known Issues & Limitations

Current Limitations (MVP Scope)

• No encryption (Phase 2)
• No cloud sync (Phase 3)
• No custom terminal emulator (Phase 2)
• Basic SFTP only (native client, no TUI)

Technical Debt

• None yet (project just started)

Security Considerations

• File permissions must be 0600 for sensitive files
• No password/key logging in errors
• Memory clearing for sensitive data (Phase 2)
