Bitbucket is Atlassian's Git-based platform for source code, pull requests, and CI/CD pipelines. The StackAI Bitbucket integration lets AI workflows and agents act on your repositories: open a pull request with Create Pull Request, kick off a CI/CD run with Trigger Pipeline, review history with List Commits, and read a file's contents at a specific revision with Get Repository Source. This lets agents participate in the development loop instead of just reporting on it.
