CI Agent

Every PR, fully tested before you review

Checksum’s CI Agent generates targeted tests for every pull request, specific to the code that changed. By the time a developer asks for review, their code has already been executed and verified.

The Problem

Code review is not code execution.

With AI, every developer is shipping more code than ever before. But PRs still get merged based on code review, not actual execution. Static analysis catches syntax errors only, not logic bugs. That means the bar for merging has not kept up with the pace of shipping, and bugs that should have been caught early are making it into main.

Code review was never designed to catch logic errors at scale. It relies on a reviewer's ability to mentally simulate execution, which breaks down as PRs get larger and more frequent. The result is a growing gap between how fast your team ships and how confident you can actually be that what shipped works. Incidents that could have been caught in CI are instead caught in production.

How the CI Agent works

Analyzes changes, not entire codebase

The CI Agent focuses specifically on the diff in each PR. It identifies the weak points introduced by that change, where things are most likely to break, and builds tests around them.

Generates 50-200 tests per PR

Instead of running a generic suite, CI Agent creates tests purpose-built for the specific change. Coverage that's precise, not broad. Every PR gets its own set of tests.

Sets up test infra automatically

Mocks databases, handles dependencies, and configures everything needed to actually run your code. No manual setup required before tests can execute.

Runs inside your existing pipeline

The CI Agent works with PyTest, Jest, and whatever frameworks your team already uses. Connect it to your CI and it runs on every PR automatically. No rip-and-replace needed.

Surfaces results before review

By the time someone opens the PR, the results are already there—which tests passed, which failed, and exactly what was tested. Every result links back to the specific change that triggered it.

Targeted coverage on every PR, automatically

The CI Agent analyzes what changed, generates tests built for that specific change, and runs them before anyone reviews a line of code.

Bugs caught while the developer has context

The CI Agent runs your code, not just reads it. Static analysis catches syntax errors; the CI Agent catches logic bugs, before they reach review.

No new tools, no new workflows

CI Agent runs inside your existing pipeline using the frameworks your team already uses. PyTest, Jest, whatever your repo uses. Connect it to your CI and it runs on every PR automatically.

Frequently Asked Questions

CI Agent generates new tests specifically for each PR. Your existing tests check that you didn't break old functionality. CI Agent tests that your new code actually works.


No. CI Agent generates tests automatically based on what changed in the PR.


You download the tests and can modify them. They're real code (PyTest, Jest, etc.), not black-box AI.


Yes. CI Agent focuses on unit and integration tests for specific PRs. End-to-end testing covers broader user flows. They complement each other.


CI Agent runs in your infrastructure. Your code never leaves your environment.


CI Agent runs in parallel with your existing CI. Most teams report faster overall cycle time because bugs are caught earlier.
