language

Run the language-checker agent to verify all foreign language phrases in your manuscript.

## What This Does

1. Scans all chapters for non-English text
2. Identifies the language of each phrase
3. Verifies grammatical correctness
4. Checks period/historical appropriateness
5. Validates dialect and register (formality level)
6. Confirms translation accuracy where translations are provided
7. Resolves author markers (`**check**`, `[verify]`, etc.)

## Usage

```
/fiction:language                    # Check all chapters
/fiction:language 5                  # Check chapter 5 only
/fiction:language swedish            # Focus on Swedish phrases only
/fiction:language 3-7                # Check chapters 3 through 7
```

## What It Catches

- **Grammatical errors** — Spelling, agreement, conjugation, case endings
- **Anachronisms** — Modern phrases in historical settings
- **Dialect mismatches** — Stockholm Swedish used where Gotland dialect expected
- **Register errors** — Wrong formality level (du/ni, tu/vous, du/Sie)
- **Translation issues** — English translations that miss nuance
- **Diacritical marks** — Missing or incorrect accents (o, u, e, etc.)

## Parallel Processing

2. Aggregate findings
3. Verify each unique phrase (avoids duplicate research)
4. Generate comprehensive report
