Design a system that turns Jira tickets into pull requests

Design an automated system that picks up a Jira ticket, uses an AI coding agent to write the change in the right repository, and opens a pull request for review.

Cover how tickets are selected and turned into a task, how the agent gets repository context, sandboxed execution and tests, how results are checked before a PR is opened, human review and feedback loops, permissions and secrets, and how you measure whether it helps.
