# Dev:interrogate

> Interrogate code changes to surface decisions, alternatives, and confidence levels. Use when user asks to "interrogate", "what decisions", "hardest part", "alternatives", or wants to understand the reasoning behind code changes.

# Interrogate Code Changes

Ask "why" instead of just reading code. Surfaces assumptions, decisions, and confidence levels.

## Workflow

@context/workflows/interrogate.md

## Input: $ARGUMENTS

Parse arguments to determine:
- **Target:** `unstaged` (default), `staged`, `changes` (staged+unstaged), `commit <hash>`, `pr <number>`, or `range <ref1>..<ref2>`
- **Mode:** `--quick` (minimal output) or `--skeptical` (extra validation)

## Gather Context

Based on target, gather the code diff:

### Target: unstaged (default)
```bash
git diff
```

### Target: staged
```bash
git diff --cached
```

### Target: changes
```bash
git diff HEAD
```

### Target: commit <hash>
```bash
git show <hash>
```

### Target: pr <number>
```bash
gh pr diff <number>
```

### Target: range <ref1>..<ref2>
```bash
git diff <ref1>..<ref2>
```

## Execute Interrogation

Apply the three core questions from the workflow to the gathered diff:

1. **What was the hardest decision?**
2. **What alternatives did you reject?**
3. **What are you least confident about?**

## Mode Behavior

- **Default:** Full explanations with confidence levels and structured tables
- **--quick:** Compact table with brief answers only
- **--skeptical:** Full output plus follow-up probes:
  - "Walk me through the logic step by step"
  - "What edge cases could break this?"
  - "If this code has a bug, where is it most likely?"

## Output

Format output per @context/workflows/interrogate.md#Output-Format based on selected mode.
