Inside a review

See what you get before you install

See an anonymized Patternis review, its limits, and the steps and costs of running your own.

This example comes from an internal owner test on October 18, 2026. Repository identifiers are replaced with placeholders. It shows one completed review, with its limits; it is not a customer testimonial or a measure of overall accuracy.

The change being reviewed

A pull request changed retry handling in a CI workflow. An owner commented @patternis review. Patternis dispatched the review to that repository's GitHub Actions runner; the result appeared on the run's summary page.

The reviewer received a snapshot of the diff. It did not execute the workflow or inspect the rest of the repository.

Review output · anonymized

Review changes

Complete response

No actionable defects identified in the supplied diff.

Limits reported with the review

Values set earlier in the workflow could not be verified from the supplied diff.
No execution trace was available to confirm the runner's date and timestamp parsing.

How the result is tied to its input

The actual run recorded the pull request, full head and base commit IDs, and a SHA-256 fingerprint of the gathered diff. Those identifiers are omitted here to keep this example anonymous. A later push needs a new review.

The source limit shown on the summary was: “Gather-time snapshot; dispatch head is not supplied. Diff only; surrounding code and execution are not verified. No approval or merge authority.”

How to read that result

“Complete response” describes completion of the provider response and the runner's format checks. It does not certify that the code is correct. Partial or malformed reviews are marked incomplete and fail the run. An empty findings list is valid when the supplied diff does not justify a defect.

The review is evidence for your decision. It does not approve or merge the pull request, and this example does not demonstrate automatic code changes.

Run a review on your own repository

Install the GitHub App on a repository you choose.
Download the runner workflow and commit it as .github/workflows/patternis-runner.yml on the default branch.
Add your Anthropic key as the repository's Actions secret PATTERNIS_PROVIDER_KEY. Your key stays in your runner.
Comment @patternis review on a pull request you are authorized to run. Follow its receipt to the GitHub Actions summary to read the review.

The App installation alone cannot run a review: the workflow and key are also required. The setup guide walks through both.

Know the separate costs

The Patternis plan covers routing and its work allowance. Your AI provider bills inference to your own key. GitHub Actions minutes can also cost money under your GitHub plan.

The current standard review makes one provider request per run, with a response budget of up to 4,096 tokens including thinking. It does not automatically retry that paid request. This is a response limit, not a dollar cap: input size, model choice and provider rates also affect cost.
