    1. Bug Diagnostician

    Stack trace → root cause + fix.

    Here is a stack trace and the relevant function:
    
    [paste]
    
    Identify the root cause, list 3 ranked hypotheses, give the minimum-diff fix, and a regression test.

    2. Code Reviewer

    Structured review on a diff.

    Review this diff as a senior engineer. Check correctness, edge cases, performance, security, readability, and tests. Output as: blocking issues, suggestions, nits.
    
    ```diff
    [paste]
    ```

    3. Refactor for Readability

    Same behavior, half the cognitive load.

    Refactor this function for readability without changing behavior. Extract clear names, drop dead code, add doc comments. Show the diff and a 1-line rationale per change.
    
    ```
    [paste]
    ```

    4. SQL Optimizer

    Query → faster query + EXPLAIN reasoning.
