Code Review Best Practices
Quick microlearning on writing better code reviews — checklist items, constructive framing, and security focus areas.
Who this is for
Software developers at any level who review pull requests, plus tech leads setting review standards for their team
Learners will be able to
- Apply a prioritised review checklist that puts correctness, tests and security ahead of style nitpicks
- Rewrite blunt review comments into specific, actionable suggestions that name the problem and a way forward
- Spot reviewer anti-patterns such as rubber stamping, nitpick storms and scope creep before they derail a pull request
- Check every diff for the highest-value security issues: unvalidated input, leaked secrets and missing authorisation checks
- Set realistic turnaround and diff-size norms that keep reviews fast without sacrificing depth
Template prompt
“Create a microlearning module on code review best practices for software developers covering review checklist items, constructive comment framing, common anti-patterns to catch, security review focus areas, and review turnaround expectations. Keep it concise and practical.”
This prompt is fully editable. Customise it to match your audience, regulations, and learning objectives before generating.
What the 5 sections cover
- 1
What a good review actually catches
A prioritised reviewer checklist covering correctness, test coverage, readability, security and performance, with guidance on what to check first when time is short.
- 2
Framing comments constructively
Before-and-after flashcards that turn blunt or vague comments into specific, actionable suggestions, including when to prefix a remark as a non-blocking nit.
- 3
Anti-patterns on both sides of the review
A scenario check on spotting rubber stamping, nitpick storms and scope creep, and how each one quietly erodes review value and team trust.
- 4
Security focus areas in every diff
A scored spot-the-issue exercise on a short code diff, hunting for unvalidated input, a hard-coded secret and a missing authorisation check.
- 5
Turnaround, diff size and team norms
Key takeaways on review latency and keeping changes small enough to review well, closing with a final scored check across the whole module.
Structure is representative — the generator adapts sections to your edited prompt and passes every package through interactivity and visual-density quality gates.
Topics covered
Make it yours
- Upload your pull request template or review checklist so the module teaches your team's actual standards rather than generic ones
- Name your primary language and framework in the prompt to get realistic diff examples in the security exercise
- Add your team's agreed turnaround and diff-size norms so the final section states them as policy, not suggestion
Frequently asked questions
How big should a pull request be for an effective review?
Smaller than most teams manage in practice. Widely cited industry research suggests defect-detection rates drop off sharply once a change grows beyond a few hundred lines, so many teams set a soft ceiling of roughly 200 to 400 changed lines. If a change must be bigger, ask the author to split it or provide a guided walkthrough of the diff.
What turnaround time should we expect on code reviews?
A common working norm is first response within one business day, and faster for small changes. Slow reviews are one of the biggest hidden drags on delivery because they force authors to context-switch and encourage oversized batches of work. The module treats turnaround as a team agreement to be made explicit, not an individual virtue.
Should code reviews cover security, or is that a separate process?
Both. Dedicated security testing and tooling still matter, but the review is often the last human check before code ships, so every reviewer should cover a short list of high-value checks: input validation, secrets in the diff, authorisation logic and unsafe dependency changes. This module teaches that baseline; it complements rather than replaces specialist security review.
Can I adapt this module to our own review checklist and stack?
Yes. Upload your team's review checklist, style guide or pull request template with the prompt, and name your language and framework. The generated examples and the spot-the-issue exercise will then reflect the code and conventions your reviewers actually see.
