Pull Request
A mechanism in collaborative software development in which a developer submits code changes to a branch and then opens a merge request, allowing team members to review and discuss before the changes are merged into the main branch.
Core Facts
Pull Requests were standardized by GitHub in 2008 as a core workflow in modern software engineering.
A pull request (PR) is a core mechanism of modern software collaboration, in which a developer completes work on an independent branch and then submits a merge request to the main codebase, which is merged after code review.
OpenHands, formerly known as OpenDevin, is an open-source agent control hub that adopts a sandbox isolation plus multi-tool orchestration architecture, capable of uniformly scheduling browsers, terminals, code editors, and external APIs.

Lauren Tan's Agents are set to fully autonomous mode: each PR triggers a strict verification loop, generating multiple verification Agents to perform fuzz testing, fixing issues on their own and repeating until mergeable.
Lauren Tan reviews merged PRs by sampling spot checks rather than fully blocking review, and focuses on error patterns that Agents repeatedly make in order to fix the environment (such as adjusting lint rules, type constraints, or skills).
Lauren Tan uses a dozen or so coordinator Agents to merge more than 2,500 PRs into production every month.
Common industry approaches to alleviating the PR review bottleneck include: front-loading mechanical checks as automated gates, introducing tiered approval for Agent changes, and using batch review interfaces.
The pace of human PRs is measured in hours or even days, whereas the output pace of Agents may be on the order of minutes, so a merge queue based on manual review will quickly become a bottleneck.
The Pull Request as a delivery form for agents offers isolation, auditability and reversibility; OpenHands's output is a PR awaiting human review, with the final decision remaining in human hands.
The dual-AI relay is feasible because: GitHub issues + PRs provide a natural collaboration interface, the cloud handles design and generation, and the local side handles real-machine verification, forming a closed loop of "make a mistake - feedback - fix".
The two AIs collaborated via GitHub issues and PRs: the cloud AI submitted code, the local agent compiled and tested it and then pasted error logs back into the issue, and the cloud AI made modifications accordingly.
When reviewing the agent's changes, Co-Review reuses the Pull Request inline-comment interaction model: the user comments on a line, the agent replies in the thread and requests changes, and then each comment is fixed as a new commit with a reply in each thread.
A PR is a standard mechanism on code collaboration platforms such as Git/GitHub: after completing changes on a separate branch, a developer submits a merge request to the mainline, which is merged into the main branch only after review and automated tests pass.
