Evaluation Criteria:
{evaluation_criteria}

Use these keys exactly inside `criteria_results` (match the bracketed key for each criterion):
{evaluation_criteria_keys}

Instructions:
1. Evaluate the bit against each criterion.
2. If any criterion fails, the overall review must be `false`.
3. Keep feedback short (max 40 words) and focus on actionable guidance when something fails. If everything passes, briefly confirm why it is strong.
4. Use boolean literals `true` or `false` (not strings) in your JSON.
5. Do not add any text outside the JSON.

Return JSON in this exact shape:

```json
{{
  "step_id": "{step_id}",
  "passes_review": true,
  "criteria_results": {{
    {criteria_results_example}
  }},
  "feedback": "Short explanation (<= 40 words)"
}}
```

Respond with the JSON only.
