Analyze the specified code for unnecessary complexity and suggest simplifications.

Scope

• If $ARGUMENTS is a file: analyze that specific file.
• If $ARGUMENTS is a directory: scan for the most complex files and prioritize.
• If $ARGUMENTS is empty: analyze recently changed files (git diff --name-only main...HEAD).

What to Look For

1. Premature abstractions — Wrappers, helpers, or utilities used only once. Three similar lines are better than a premature abstraction.
2. Over-engineering — Feature flags, backwards-compatibility shims, or configurability that isn't needed yet.
3. Dead code — Unused imports, unreachable branches, commented-out blocks.
4. Unnecessary indirection — Layers that just pass through, factories that build one thing, interfaces with one implementation.
5. Complex conditionals — Deeply nested if/else, long boolean chains that could be simplified.
6. Duplicated logic — Copy-paste code that should be a function (only if used 3+ times).

Output Format

Write findings to scratch/simplify_latest.md:

## Simplification Report: <scope>

### High Impact
- [file:line] What to simplify and why. Estimated reduction: X lines.

### Medium Impact
- [file:line] Description.

### Low Impact / Nitpicks
- [file:line] Description.

### Summary
- Total opportunities: N
- Estimated net line reduction: X
- Recommendation: [act now / defer / skip]

Return a ≤5 line summary to the main context.

Rules

• Don't suggest changes that would break existing tests.
• Don't remove code that handles real edge cases — only remove genuinely dead paths.
• Simplicity > cleverness. The goal is clarity, not fewer characters.
• Present options — don't apply changes without approval.
