g1t/services/work/src/lifecycle.rs
Pick any line to see why it is the way it is: the commit, the pull request and issue it came from, and what the agent was thinking.
| Agents as a team: lifecycle, merge queue, billing and a new shell | 1 | //! Seeing a pull request through. Once a g1t agent has made a change, g1t |
| 2 | //! takes each remaining step itself: the acceptance checks, a review by | |
| 3 | //! another agent, sending the author back to address what either found, | |
| 4 | //! and catching up when the branch it would land on has moved. It stops | |
| 5 | //! when the pull request is ready for a person to merge, or when it has | |
| 6 | //! tried and a person has to decide. | |
| 7 | //! | |
| 8 | //! This service decides what the next step is and claims it. The runner | |
| 9 | //! service asks, on every event that could change the answer, and carries | |
| 10 | //! the step out in a sandbox. | |
