Code Review Focused on One Dimension

    Review the code below for **{{focus}}** issues only (for example: security, performance, readability, correctness, or maintainability). Ignore unrelated concerns so the review stays sharp.

Code:
{{code}}

Context (optional — language, framework, what it's supposed to do, constraints):
{{context}}

Return your findings as a table with these columns:

| Severity (blocker / high / medium / low) | Location (line or function) | Issue | Why it matters | Suggested fix |

Guidelines:
- Cite a specific line or function for every finding — no vague, whole-file remarks.
- Order findings by severity, most serious first.
- If a piece of code is genuinely good and worth keeping as-is, you can note that briefly at the end.
- If something looks wrong but you can't be sure without more context, say so instead of guessing.
