## P0 - Critical Priority (Week 1-2)

**Total**: 6 tasks, 22-33 hours

### Architecture Issues

| ID | Task | Effort | Impact |
|----|------|--------|--------|
| ARCH-01 | [Refactor Large CLI Module](p0/ARCH-01-refactor-cli.md) | 8-12h | HIGH |
| ARCH-02 | [Add Abstract Base Classes](p0/ARCH-02-add-abstract-base-classes.md) | 4-6h | HIGH |

**Why Critical**:
- ARCH-01: 1,989-line file blocks contributors, violates SRP
- ARCH-02: Enables extensibility, required for plugin architecture

### Performance Issues

| ID | Task | Effort | Impact |
|----|------|--------|--------|
| PERF-01 | [Fix Unbounded Performance Tracker Cache](p0/PERF-01-fix-tracker-cache.md) | 2-3h | CRITICAL |
| PERF-02 | [Cache Agent Definition Files](p0/PERF-02-cache-agent-definitions.md) | 1-2h | HIGH |

**Why Critical**:
- PERF-01: OOM risk in production with 10K+ executions
- PERF-02: 1-2ms overhead on every execution (50-100% speedup possible)

### UX Issues

| ID | Task | Effort | Impact |
|----|------|--------|--------|
| UX-01 | [Add Quiet Mode for CI/CD](p0/UX-01-add-quiet-mode.md) | 3-4h | HIGH |
| UX-02 | [Add Interactive Setup Wizard](p0/UX-02-interactive-setup.md) | 4-6h | HIGH |

**Why Critical**:
- UX-01: Blocks CI/CD integration
- UX-02: 15min → 5min onboarding time (67% improvement)
