# Inspecting Changes

Static analysis of code changes BEFORE execution.

## Workflow Checklist

Copy and track progress:

```
Analysis Progress:
- [ ] Step 1: Parse mode (quick/medium/deep) from arguments
- [ ] Step 2: Detect changes (git diff or explicit path)
- [ ] Step 3: Execute phases for selected mode
- [ ] Step 4: Generate report with findings
```

**Step 1: Parse mode**
- If mode in arguments → use it
- If no mode → use AskUserQuestion with options: Quick, Medium, Deep

**Step 2: Detect changes**
- Default: `git diff --name-status` (uncommitted)
- With path: `git diff --name-status -- <path>`
- With ref: `git diff --name-status <ref1>..<ref2>`

**Step 3: Execute phases by mode**

| Mode | Phases | Use Case |
|------|--------|----------|
| quick | 1, 2, 8 | Pre-commit, small changes |
| medium | 1, 2, 2b, 3, 5.1, 8 | Standard review |
| deep | 1, 2, 2b, 3, 4, 5, 6, 7, 8 | Major features, pre-deploy |

**Step 4: Generate report**
- See [modules/output.md](modules/output.md) for format templates

## Tool Rules

**Read-only analysis.** Never modify files. Never execute code.

Allowed:
- `git diff`, `git log`, `git show` (read-only)
- Read, Grep, Glob tools

Every finding MUST include `file:line` reference.
