Compare Two Code Review Prompts

'Review my code and be detailed' against a structured review prompt — compared on structure, because review quality follows review structure.

Open in Prompt Comparator

Overview

Code review prompts reward structure more than any other category: a reviewer that checks named categories with severities beats one told to 'be detailed' every time. The loaded pair compares exactly that — an unstructured ask against a prompt with review criteria, an exclusion rule, and an output contract. The structure score tells the story; the rest of the report shows what each version of you would have to clean up afterwards.

How to use this resource

Compare with Structure focus

The loaded pair isolates the structure dimension: named criteria and an output contract versus 'be thorough'.
Read the exclusion rule's effect

'Skip linter-catchable style' is a constraint that removes noise — note how it shows up in B's strengths.
Check the contradiction angle

'Be detailed and don't miss anything' invites exhaustive output with no priorities — the risk section explains why that's a gap, not rigor.
Promote the winner into your workflow

Apply B's remaining suggestions, then save it where the team actually reviews — PR template or saved reply.

Why This Works

Named categories with a priority order make coverage verifiable — 'thorough' doesn't
Severity labels in the output contract turn findings into a triage list instead of an essay
Exclusion rules are as load-bearing as inclusion rules in review prompts: they buy signal by deleting noise

Best for

Teams using AI review as a first pass before human review
Review prompts that will run on security-sensitive code paths
Developers tired of wading through style nitpicks to find the real findings

Not for

Generating the review system prompt itself — the System Prompt Generator covers that
Comparing two diffs or two code versions — this compares the prompts, not the code

Use cases

Picking the review prompt your team pastes into every PR thread
Comparing your ad-hoc review ask against a structured template before standardising
Demonstrating why 'don't miss anything' produces noise instead of coverage

FAQ

What dimension does this comparison actually score the two review prompts on?

It isolates structure, because review quality follows review structure more than any other category. The pair contrasts prompt A's "be detailed and thorough and don't miss anything" against prompt B's named priority order (correctness, security, coverage) with an exclusion rule and a severity output contract. The Prompt Comparator scores and reports; it doesn't run either prompt on code.

Is this for comparing two versions of my code or two prompts?

Two prompts. It weighs prompt A against prompt B — the review instructions themselves — not two diffs or code versions. For comparing code you'd want a different tool. Here the report shows how prompt B's exclusion rule ("skip style issues a linter would catch") and severity contract turn findings into a triage list instead of the essay "don't miss anything" invites.

Review this code and tell me what's wrong with it. Be detailed and thorough and don't miss anything important.

Prompt B

Review this pull request for correctness, security, and missing test coverage — in that priority order.
Flag anything touching authentication or input validation explicitly.
Skip style issues a linter would catch.
Output: numbered findings with severity (high/medium/low), then a short action-item list for the author.
