From a GitHub issue
to a fix you can review.

Give Nine the GitHub issue and intended behavior. It investigates the repository, prepares a focused change, and brings a pull request back for your engineers to review.

A focused pull request, with reasoning and checks.

Investigate the GitHub issue about webhook retries creating duplicate updates. Prepare a pull request with a fix and checks for review.

Illustrative workflow and deliverable.

Fix for duplicate webhook updates

The retry path can apply the same event twice. The proposed change checks the event ID before applying an update.

Found
Repeated delivery reaches the update path without checking whether the event was already handled.
Proposed change
Check the event identifier before applying the update; retain the ability to retry failed processing.
Review focus
When the event is marked complete, and how that interacts with a failed first attempt.

Checks included

  • First delivery
  • Duplicate delivery
  • Failed-attempt retry

Supporting context

  • GitHub issue
  • GitHub retry-path files and commit references
  • Relevant tests and GitHub check results

Illustrative deliverable, for your team’s review.

How Nine gets there.

Trace the failure.

Read the GitHub issue and repository files. Follow repeated delivery through the update path and identify the missing event-ID check.

Connect the cause to the reported symptom.

Prepare a focused change.

Prepare the fix on a GitHub branch and exercise the relevant failure cases in the configured development environment.

Preserve retries when an earlier attempt fails.

Bring it back for review.

Open a GitHub pull request with the reasoning, check results, and review notes.

Keep merge and release decisions with your engineers.

The result starts
a conversation.

A GitHub pull request, with a review summary back in your conversation.

Make sure a failed first attempt can still be retried.

Nine

I’ve included a failed-attempt retry case in the checks and called out when an event is marked complete in the review notes.

Where the work lands

Proposed pull request · GitHub

A GitHub pull request, with a review summary back in your conversation.

Access needed

A GitHub App installation with access to the relevant repository, issue, and checks, plus permission to create a branch and pull request. An appropriate development environment is needed to run the agreed tests; we confirm that setup during onboarding.

Your team’s part

Engineers

Give Nine a bounded issue, the expected behavior, and the context it needs. Get a proposed change with reasoning and relevant checks, so your engineers can focus on review and decide what to merge and release.

Bring the issue you’d like to delegate.

Tell us about the codebase, expected behavior, and reviewable result your engineers need. We’ll discuss GitHub repository access and a bounded first task.
