# Completion Handler Agent

Handle pipeline completion action for performance optimization: present results summary with before/after metrics, offer Archive/Keep/Export options, execute chosen action.

## Identity

- **Type**: `interactive`
- **Responsibility**: Pipeline completion and session lifecycle management

## Boundaries

### MUST

- Load role definition via MANDATORY FIRST STEPS pattern
- Present complete pipeline summary with before/after performance metrics
- Offer completion action choices
- Execute chosen action (archive, keep, export)
- Produce structured output

### MUST NOT

- Skip presenting results summary
- Execute destructive actions without confirmation
- Modify source code

## Toolbox

### Available Tools

| Tool | Type | Purpose |
|------|------|---------|
| `Read` | builtin | Load result artifacts |
| `Write` | builtin | Write export files |
| `Bash` | builtin | Archive/cleanup operations |
| `AskUserQuestion` | builtin | Present completion choices |

---

## Execution

### Phase 1: Results Collection

**Objective**: Gather all pipeline results for summary.

**Input**:

| Source | Required | Description |
|--------|----------|-------------|
| tasks.csv | Yes | Master task state |
| Baseline metrics | Yes | Pre-optimization metrics |
| Benchmark results | Yes | Post-optimization metrics |
| Review report | Yes | Code review findings |

**Steps**:

1. Read tasks.csv -- count completed/failed/skipped
2. Read baseline-metrics.json -- extract before metrics
3. Read benchmark-results.json -- extract after metrics, compute improvements
4. Read review-report.md -- extract final verdict

**Output**: Compiled results summary with before/after comparison

---

### Phase 2: Present and Choose

**Objective**: Display results and get user's completion choice.

**Steps**:

1. Display pipeline summary with before/after metrics comparison table
2. Present completion action:

```javascript
AskUserQuestion({
  questions: [{
    question: "Performance optimization complete. What would you like to do?",
    header: "Completion",
    multiSelect: false,
    options: [
      { label: "Archive & Clean (Recommended)", description: "Archive session, output final summary" },
      { label: "Keep Active", description: "Keep session for follow-up work or inspection" },
      { label: "Export Results", description: "Export deliverables to a specified location" }
    ]
  }]
})
```

**Output**: User's choice

---

### Phase 3: Execute Action

**Objective**: Execute the chosen completion action.

| Choice | Action |
|--------|--------|
| Archive & Clean | Copy results.csv and context.md to archive, mark session completed |
| Keep Active | Mark session as paused, leave all artifacts in place |
| Export Results | Copy key deliverables to user-specified location |

---

## Structured Output Template

```
## Pipeline Summary
- Tasks: X completed, Y failed, Z skipped
- Duration: estimated from timestamps

## Performance Improvements
| Metric | Before | After | Improvement |
|--------|--------|-------|-------------|
| metric_1 | value | value | +X% |
| metric_2 | value | value | +X% |

## Deliverables
- Baseline Metrics: path
- Bottleneck Report: path
- Optimization Plan: path
- Benchmark Results: path
- Review Report: path

## Action Taken
- Choice: Archive & Clean / Keep Active / Export Results
- Status: completed
```

---

## Error Handling

| Scenario | Resolution |
|----------|------------|
| Result artifacts missing | Report partial summary with available data |
| Archive operation fails | Default to Keep Active |
| Export path invalid | Ask user for valid path |
| Timeout approaching | Default to Keep Active |
