What Is Linear Integration for Code Review?

Linear integration for code review connects Linear issues to the pull requests that implement them, so reviewers can see what a change was meant to do. The integration links an issue to its PR through the issue ID in the branch name or PR title, and brings the issue’s description into review.

Linear is a project and issue tracking tool used by many software teams. Linear’s GitHub and GitLab integrations link PRs to issues and update issue status as work moves.

A code reviewer that reads the linked Linear issue can check the change against the request as well as the code.

What Changed in Linear Code Review in 2026

In 2026 Linear moved from linking PRs to issues toward hosting review and coding agents itself, which put the issue closer to the code than before.

Linear added its own agent. Linear Agent launched as an in-product agent that works from workspace context such as issues and roadmaps (March 24, 2026, Linear).

Review moved into Linear. Linear Diffs let teams review PRs inside Linear, with reviews synced to GitHub, guided reviews and a Review Inbox (May 28, 2026, Linear).

Linear kept people accountable. Linear’s own launch note said agents "generate large volumes of code, but individuals are still accountable for the changes that merge" (May 28, 2026, Linear).

Issues started to write code. Coding sessions let Linear Agent write code with Claude Code or Codex and return a diff for review (June 11, 2026, Linear), and Copilot’s cloud agent for Linear became generally available (July 23, 2026, GitHub).

Diffs grew to cover stacks. Linear added stacked PRs to Diffs, with review, CI and merge status for each PR (October 8, 2026, Linear).

Matching code to intent is still hard. 13.2% of surveyed developers said understanding whether code matches its intent is their greatest AI code review challenge (September 23, 2026, Qodo’s State of AI Code Quality report).

When an issue can turn into code with little human writing in between, the issue becomes the best record of intent a reviewer has, which is where Qodo’s take starts.

How the Linear GitHub Integration Links Issues and PRs

The Linear GitHub integration links a PR to an issue when the issue ID, such as ENG-123, appears in the branch name, the PR title or the PR description. Once linked, Linear shows the PR on the issue and can move the issue’s status as the PR is opened, reviewed and merged.

Linear also has integrations for GitLab, Slack and other tools. For code review, the link between issue and PR is the part that matters, because it tells the reviewer which issue to read.

What a Reviewer Gets From the Linked Issue

The linked issue answers questions the diff can’t:

• What was asked for. The title and description say what the change should do.
• What’s in scope. Subtasks and labels show what belongs in this PR and what doesn’t.
• What it should look like. Screenshots and attachments show the expected result.
• What done means. Acceptance criteria, when they’re written down, give the reviewer a checklist.

Linear Integration Options for Code Review

Qodo’s Take: Write Acceptance Criteria Where the Reviewer Can Read Them

A reviewer that reads Linear issues can only check what the issue says. If the acceptance criteria sit in a custom field, a separate doc or someone’s head, the review checks the code against a thinner version of the request.

In Qodo’s enterprise evaluations, teams asked whether review could check intent and acceptance criteria, and how much ticket quality mattered.

The practical answer was simple: put acceptance criteria in the issue description. Qodo reads the issue description, so a short list there gives review something concrete to check.

Qodo reads the linked Linear issue on each PR and reviews the change against it, separate from whichever tool or agent wrote the code. You shouldn’t review code with the same tool that wrote it, and when an agent turns an issue into a PR, an independent check against that issue matters more.

Qodo is the best AI code review platform to integrate with Linear because it reads the linked issue’s description, subtasks, labels and images on every PR, and helps catch gaps between the issue and the code before human review.

Qodo Reads These Linear Fields

Qodo fetches the issue’s title, description, subtasks, attachments (up to three images, plus embedded images) and labels. Custom fields and acceptance criteria fields aren’t fetched (last checked October 2026, Qodo’s docs). Qodo reads from Linear and reports its findings on the PR.

Qodo Finds the Issue From the Branch Name

The issue ID has to appear at the start of the branch name or right after a /, for example PLT-2837 or feature/PLT-2837. Names such as fix-PLT-2837 or [PLT-2837] aren’t matched (Qodo’s docs).

Matching ignores case. Qodo also finds the issue from a Linear link or ID in the PR description, and short IDs and branch-name detection both need linear_base_url under [linear] in the configuration (Qodo’s docs).

Qodo Checks the PR Against the Linked Issue

Requirement-aware review is on by default once the Linear integration is connected. Qodo compares the PR with the linked issue and reports what’s missing as findings rather than explicit compliance statuses (last checked October 2026, Qodo’s docs).

Qodo Checks Linked Spec Pages in a Research Preview

When the PR also links a specification page, the Spec Agent, a Research Preview, adds requirement gap findings against that spec (Qodo’s docs).

Confluence and Notion spec pages are Research Preview integrations. Qodo uses a Confluence page linked in the PR description, or one linked from a Linear issue when the PR description links that issue (last checked October 2026, Qodo’s docs).

Qodo Example: The Issue With the Criteria in the Wrong Place

Context: a product analytics company with about 150 engineers starts many PRs as Linear issues assigned to a coding agent. The company’s engineering manager wants review to check each PR against its issue.

Problem: review comments rarely mention the issue, because the team keeps acceptance criteria in a custom field, and Qodo doesn’t fetch custom fields.

How Qodo helped: the manager asks the team to add a short "Acceptance criteria" list to each issue description. On the next agent PR, Qodo reads the description and flags that the change handles the new export format but skips the error state the issue asks for.

Outcome: the developer adds the missing error state before human review, and the team now writes acceptance criteria where the reviewer can read them.
