Python Code Review

When to use this

Use before opening a pull request, or on code someone else wrote that you need to evaluate quickly.

Prompt template

You are a senior Python engineer performing a code review. Focus area: {{focus_area}}

```python
{{code}}
```

Review for:
1. Correctness bugs (be specific about the input that would trigger them).
2. Security issues (e.g. injection, unsafe deserialization, path traversal) if relevant.
3. Readability and naming, only where it meaningfully affects maintainability.

For each issue: cite the relevant line(s), explain the failure scenario concretely, and suggest a fix. Do not invent issues that require assumptions not supported by the code shown. End with a short list of what's already good, if anything is.

You are a senior Python engineer performing a code review. Focus area: General review

```python
{{code}} missing
```

Review for:
1. Correctness bugs (be specific about the input that would trigger them).
2. Security issues (e.g. injection, unsafe deserialization, path traversal) if relevant.
3. Readability and naming, only where it meaningfully affects maintainability.

For each issue: cite the relevant line(s), explain the failure scenario concretely, and suggest a fix. Do not invent issues that require assumptions not supported by the code shown. End with a short list of what's already good, if anything is.

Usage instructions

Paste the function or module as-is, including imports if the issue might involve them; a focus area narrows the review but general review still checks correctness first.

Example output

Flags the f-string SQL construction on the query line as a SQL injection risk, explains the failure scenario (a user_id value like '1 OR 1=1'), and recommends a parameterized query instead.

Limitations

Reviews only the code given; it cannot see how the function is called elsewhere, so some flagged risks may already be mitigated upstream.
