Writing code got easy, reviewing code got hard
Mastering Agentic Review is the real advantage

After agents produce 10x code, review quality decides product success. Structured checklists + tools + process turn review into repeatable strength.

Why review became the hardest part

Agents can quickly produce code that appears to run, but often lacks edge cases, implicit assumptions, and long-term maintainability. Humans must shift attention from writing to verification and correction.

Core Agentic Review checklist

Intent & correctness

Was the task goal correctly understood? Is the critical path logic consistent with requirements?

Boundaries & error handling

Exceptions, concurrency, nulls, permissions covered? Agents frequently miss these.

Maintainability & observability

Naming, module boundaries, logging, metrics clear? Can the next person understand quickly?

Security & performance

Injection, privilege escalation, N+1 queries, leaks introduced?

Use QCode to assist review

QCode dashboard can filter call history by session, model and token volume, making it easy to locate suspicious large generated code blocks quickly. Combine with diff and trace for higher efficiency.

Agentic Review FAQ

Isn't the checklist too heavy?

It is a checklist, not a report every time. Teams can turn frequent items into a PR template and complete core checks in 5 minutes.

Are tests generated by agents trustworthy?

Check coverage and boundaries. Prioritize reviewing whether the tests actually exercise business rules, not just happy paths.

What if review speed can't keep up with generation?

Use layering: AI self-check + small sandbox run first, then human high-value review. Low-value changes go to CI gates.

How does QCode help?

Usage visualization + model tags let you quickly find "which model in which session produced this big PR", giving context during review and greatly improving efficiency.
