# Subtasks Execution Guide: Agentic AI Coders
**Generated**: 2025-01-28
**Context Package**: [`/requests/agentic-ai-coders/context/`](./context/)
**Task Files**: [`/requests/agentic-ai-coders/tasks/`](./tasks/)
## Execution Overview
This guide provides the execution strategy for implementing the "agentic AI coders in a tab in the TUI" feature through 8 atomic subtasks. The implementation follows a tmux-style interactive design where AI coders run as persistent sessions that users can attach to and detach from, with real-time error reporting from Brummer to the AI.
**Design Vision**: "This design makes AI coders feel like pair programming sessions where Brummer acts as the development environment providing real-time feedback to both the human and AI."

## Risk Mitigation
### High-Risk Integration Points
**Risk**: TUI integration complexity
**Mitigation**:
- Implement TUI components incrementally
- Test each component independently
- Use existing TUI patterns as templates
**Risk**: Event system coordination
**Mitigation**:
- Implement event types before handlers
- Test event flow with simple payloads first
- Monitor for event loops and performance issues
**Risk**: Process manager integration
**Mitigation**:
- Use existing process patterns
- Implement bridge pattern for loose coupling
- Test with mock AI coder processes first
### Dependency Management
**Critical Dependencies**:
1. **Task 01 → Tasks 02, 04, 05**: Core service interface
2. **Task 01 → Task 06**: Event emission patterns
3. **Tasks 01-06 → Task 07**: Complete implementation for testing
4. **Tasks 01-07 → Task 08**: Working system for documentation
**Contingency Plans**:
