Code Review Habits for AI Code

Code Review Habits for AI Code

Code review habits for AI-generated code are the team routines that make agent output easy to inspect, test, and merge safely. This guide is for Cursor and teams using coding agents, MCP integrations, and GitHub pull requests. The practical answer is to review the diff, the agent instructions, the tool access, and the tests, not the whole chat transcript. Start with one repo rule, one MCP boundary, and one PR checklist before adding heavier governance.

A code review habit is a repeated, lightweight check that catches risk at the same point in the workflow every time. That matters for AI coding training for teams because the hard part is not teaching everyone a prompt. The hard part is making generated code reviewable by people who were not in the agent session.

Start reviews at the instruction boundary

For teams trying to implement code review habits for ai-generated code, the first review target is the instruction boundary. Before a reviewer studies the diff, they should know what the agent was allowed to change, which rules it followed, and which files were out of scope.

In Cursor, this usually means keeping small repo rules close to the code they govern. A frontend package can have a local rule for component patterns. A migrations folder can have a stricter rule that says generated SQL needs human approval before it is run.

A useful lesson from Christopher Burns of Inth, in an AI Engineer YouTube talk about making an open source library legible to language models is that models reward clear public signals. The same is true inside a private repo. Agents behave better when your conventions are written where the tool can find them.

Don't put all guidance into one giant root file. It feels tidy, but reviewers cannot tell which rule mattered for this change. Local scope beats a policy wall.

A small AGENTS.md boundary can be enough:

  • Agents may edit app/**, packages/ui/**, and tests for those files.
  • Agents must not edit infra/**, billing/**, or database migrations without a linked ticket.
  • Generated changes need a test note in the pull request, even when no tests were added.

That is not bureaucracy. It is a map for the next human.

Compare the review habit to the risk

Not every AI-generated change needs the same review path. A typo fix, a component refactor, and an agent that used an MCP server to read private tickets do not carry the same risk.

Use a simple comparison before you standardize the workflow:

Criteria Diff-only PR review Cursor IDE review pass Agent plus MCP boundary review
What reviewers inspect Final code diff, tests, and PR notes Diff plus the relevant Cursor rule, prompt summary, and changed files Diff plus tool permissions, external data touched, and any generated commands
Best fit Small, low-risk changes in familiar code Refactors, test generation, UI changes, and agentic coding work inside the repo Jira, GitHub, Slack, database, Figma, or document-store access through MCP
Concrete artifact PR checklist .cursor/rules/*.mdc rule and reviewer checklist Read-only MCP default, permission table, and handoff receipt
Trap to avoid Trusting the green diff without asking why it changed Replaying the whole chat instead of reviewing the durable instruction Giving the agent write access before the team knows how to audit reads

Verdict: diff-only review wins for small and obvious changes, Cursor IDE review wins when the reviewer needs repo context, and MCP boundary review wins when the agent touched systems outside the codebase. Most engineering team ai adoption programs should start with the middle column, then add MCP checks as integrations become real.

This is also a good place to connect the practice to broader AI coding governance. Governance should show up as reviewable workflow, not as a PDF nobody opens during a pull request.

Make MCP access boring and visible

Model Context Protocol, or MCP is a standard way for coding agents to connect to external tools and data sources. In practice, MCP can let an agent inspect GitHub issues, Jira tickets, design files, docs, databases, or internal services.

That is powerful. It also changes what code review means. The reviewer is no longer only asking whether the code compiles. They are asking whether the agent used the right context, whether that context was allowed, and whether any write action happened outside the repo.

Start MCP integrations as read-only unless there is a strong reason not to. A GitHub issue reader is easier to audit than an agent that can label issues, close tickets, and push commits in the same run.

For a real workflow, add a tiny permission table to the pull request template:

System Access used Why it was needed Write action?
GitHub issues Read Confirmed acceptance criteria No
Figma Read Matched spacing tokens No
Database None Not needed No

Don't treat MCP as invisible plumbing. If the agent used outside context, make that context part of the review record.

For a concrete example of where this is going, see how agent workflows can move from tickets to code in CoolPlugz Turns Jira Tickets Into PRs. The same review question appears there too: what did the agent read, what did it change, and who checked the boundary?

Paste a Cursor review checklist into the repo

The best checklist is short enough that reviewers actually use it. Put it near the work, wire it into Cursor rules, and make it part of pull request review.

Here is a starter .cursor/rules/ai-generated-code-review.mdc rule you can paste into a repo and tune in your next AI coding workshop:

---
description: Use this when reviewing AI-generated changes before merge.
globs: **/*
alwaysApply: false
---

When reviewing AI-generated code in this repo, check:

- [ ] Scope: The PR explains which files the agent was asked to change and which files were off limits.
- [ ] Diff: The reviewer can understand the final diff without replaying the full agent chat.
- [ ] Tests: The PR names the tests run, the tests added, or the reason no test was useful.
- [ ] Architecture: The change follows the nearest AGENTS.md, package rule, or local convention.
- [ ] Security: The agent did not introduce new secrets, unsafe logging, broad permissions, or unreviewed dependencies.
- [ ] MCP: Any external context used by the agent is listed, including read or write access.
- [ ] Commands: Risky commands, migrations, deploy steps, and generated scripts were reviewed by a human before execution.
- [ ] Ownership: A human owner can explain the change and respond to follow-up bugs.

Suggested AGENTS.md boundary:

- Agents may propose changes across this package.
- Agents may not run destructive commands, rotate credentials, edit production config, or apply migrations.
- Any generated dependency change needs a reviewer note explaining why the dependency is needed.

Keep the wording boring. Review checklists fail when they become moral essays. The job is to make the next review five minutes clearer.

The limitation is that a checklist will not save a team from vague ownership. If nobody owns the agent output, the pull request is not ready, no matter how good the tool is.

Common questions

Do AI-generated tests need the same review as AI-generated product code?

Yes, AI-generated tests need review because weak tests can make bad code look safe. Review whether the test would fail before the implementation change, whether it asserts behavior instead of snapshots only, and whether it hides flaky timing or broad mocks. Tests are part of the product contract.
